Define the Role: Avoid Incomplete or Unclear Descriptions

When job descriptions are vague – like "Looking for a mobile developer with experience" – they often lead to a flood of unqualified applicants and mismatches. This wastes time for both employers and candidates.

According to a Monster survey, 64% of job seekers won’t respond to ads with unclear or poorly written titles. While 72% of hiring managers believe their job descriptions are clear, only 36% of candidates agree. This disconnect can result in attracting the wrong candidates, slowing down the hiring process, and making it harder to pinpoint the skills you actually need. And when expectations aren’t aligned, new hires may quickly become dissatisfied, leading to turnover and wasted resources.

The key to fixing this? Be specific. Instead of generic phrases, craft a description that clearly outlines the role, the required platforms, and the scope of work. This helps candidates evaluate their fit before they even apply.

State Platform Requirements

One common mistake in mobile developer job postings is failing to specify the platforms involved. Are you looking for someone to build for iOS, Android, or both? Does the role require experience with cross-platform frameworks? These details not only shape the candidate pool but also set expectations for the technical challenges ahead.

For example, if you need native development, clarify whether the candidate should know Java/Kotlin for Android or Swift/Objective-C for iOS. If cross-platform expertise is required, mention frameworks like React Native, Flutter, or Xamarin. Keep in mind that Android development often involves handling device fragmentation, while iOS development is generally more straightforward due to a smaller range of devices.

Also, think about your target audience. iOS users typically have higher incomes and spend more on in-app purchases, whereas Android reaches a broader and more diverse audience. If your project involves cutting-edge technologies like Apple Vision Pro, augmented reality, or machine learning, make sure to highlight these requirements. Similarly, if cross-platform frameworks are part of your tech stack, be upfront about it.

By clearly defining the platform requirements, you help candidates understand the role’s technical expectations and ensure they align with your needs.

List Project Scope and Goals

Beyond the platforms, spell out what the role entails so candidates can determine if their skills match. Is the position focused on building a new app from scratch? Maintaining an existing codebase? Or maybe adding features to an established product? Each of these scenarios requires different expertise and approaches.

For instance, hiring someone to develop a minimum viable product (MVP) demands speed and pragmatism, while bringing in an expert to optimize a high-traffic app requires deep knowledge of memory management, caching, and scalability.

Additionally, clarify the project timeline. Is this a short-term gig to launch a product quickly? Or a long-term role where the developer will grow alongside the app?

Context matters. Whether it’s a healthcare app requiring HIPAA compliance, a gaming app that needs performance tuning, or an e-commerce platform with secure payment integration, these details allow candidates to assess whether their experience aligns with your goals. By outlining the project scope and objectives, you attract candidates who not only meet the qualifications but are genuinely excited about the opportunity.

Technical Requirements: Avoid General Statements

Vague requirements not only confuse candidates but also waste valuable time and resources. In fact, unclear job descriptions contribute to 64% of tech roles remaining unfilled and lead to costly project setbacks – 51% go over budget, and 47% fail to meet their objectives.

To attract the right talent, be precise about the technical skills you need. For instance, instead of saying "mobile development experience", specify whether you’re looking for expertise in Swift (iOS), Kotlin (Android), or React Native (cross-platform). This level of detail helps qualified candidates identify themselves while discouraging unqualified applicants. Clear requirements lay the groundwork for defining both essential and preferred skills.

List Required Skills

Start by outlining the programming languages and frameworks crucial for your project. For native iOS development, specify Swift proficiency and, if relevant, experience with SwiftUI for UI design. For Android projects, highlight Kotlin expertise and mention whether familiarity with Jetpack Compose is necessary.

Since many mobile apps rely on backend services, emphasize API integration skills. Specify whether candidates need experience with tools like RESTful APIs, GraphQL, OAuth authentication, or cloud-based integrations. Database management is another key area – clarify whether knowledge of SQLite, Room (for Android), Core Data (for iOS), or cloud solutions like Firebase is essential.

Security is critical, especially for applications handling sensitive data. Make it clear if candidates must understand practices like data encryption and secure token handling.

When listing these skills, define the expected proficiency level. For example, instead of broadly stating "Swift experience", specify whether you require basic familiarity or advanced expertise gained through years of production work. This ensures candidates’ qualifications align with your project’s demands.

Add Preferred Skills and Tools

To further refine your candidate pool, include a section for preferred skills. These are not mandatory but can help attract highly skilled professionals. For example, mention advanced technologies like 3D scanning, augmented reality, or machine learning integration, which could add value to your project.

"Preferred is something we would like to have. If we have multiple people who can all do the Required Skills then Preferred Skills will serve as a way to differentiate them."

  • Ed Ahrenhoerster, Manager of web developers

Highlight technologies that align with your future goals. For instance, an e-commerce app might benefit from candidates experienced with payment processing APIs or fraud detection systems, while gaming apps could value expertise in graphics optimization or real-time multiplayer frameworks.

Don’t forget to mention relevant development tools and workflows. Specify familiarity with IDEs like Android Studio or Xcode, version control systems, continuous integration tools, or testing frameworks. Additionally, soft technical skills – like proficiency in code review processes, automated testing, performance optimization, or accessibility standards – can signal a candidate’s ability to create maintainable and scalable applications.

Set Clear Responsibilities and Expectations

Unclear job descriptions can lead to hiring mistakes that cost your company thousands. For instance, when job postings use vague phrases like "rise to new challenges" without specifying actual responsibilities, 64% of job seekers won’t even apply. On top of that, unclear expectations are linked to 80% of employee turnover, with mismatched hires costing between $15,000 and $17,000 each. These missteps not only drain resources but also add to the broader issue of disengaged employees, which costs U.S. businesses nearly $350 billion annually. Each disengaged employee alone represents at least $2,246 in losses for your business.

To prevent these pitfalls, your job description needs to clearly define how the mobile developer will integrate into your team. This level of transparency ensures candidates can self-assess their fit for the role and sets realistic expectations from the outset. Additionally, outlining daily tasks in detail will help solidify these expectations.

Define Daily Tasks

Be specific when describing the role’s daily responsibilities. Instead of using broad phrases like "develop mobile applications", break it down into actionable tasks. For example, will the developer spend mornings writing and reviewing code in Swift or Kotlin? Are they expected to join daily stand-up meetings or contribute to sprint planning sessions?

Frequency matters too. Mention that they’ll collaborate with UI/UX designers twice a week for wireframe reviews, debug and optimize app performance, and integrate backend services for feature releases. If maintaining technical documentation is part of the job, spell it out – whether it’s documenting code changes for pull requests or updating API references.

Don’t forget research and learning. Mobile developers often dedicate time to staying current with platform updates, such as the latest SDKs from Apple and Google. If the role involves automated testing or conducting code reviews, make sure that’s clear as well.

Communication tasks are another key area to highlight. Will they provide weekly progress updates to stakeholders or translate technical details for non-technical team members? Including these specifics helps candidates understand the full scope of their responsibilities beyond just coding. Also, clarify how they’ll collaborate with the team on a daily basis.

Explain Team Collaboration Requirements

Mobile development is rarely a solo endeavor, so it’s crucial to outline how the developer will work with others. Teams that collaborate effectively are five times more likely to excel compared to those with poor collaboration practices. Be clear about which teams the developer will interact with. For example, will they work closely with product managers to refine features or partner with QA engineers during testing? If your process involves design handoffs, explain how developers will receive and implement design specifications.

Address both technical and non-technical collaboration. For technical tasks, include activities like code reviews, pair programming, or architecture discussions. Companies that define these processes often see a 50% reduction in integration issues when using version control systems.

For non-technical collaboration, describe how developers will engage with business stakeholders, marketing teams, or customer support. Will they attend sprint retrospectives, participate in user feedback sessions, or contribute to product planning meetings? Specifics like these help candidates understand how they’ll contribute beyond their technical expertise.

Also, outline the tools and processes your team uses to communicate. Whether it’s Slack for daily updates, weekly video calls, or project management tools like Trello or Jira, being upfront about these details helps candidates visualize their day-to-day workflow.

Lastly, clarify the developer’s role in team dynamics. Will they mentor junior team members, assist in technical decision-making, or lead particular projects? Including these points gives candidates a clear picture of their responsibilities and how they’ll fit into the overall team structure.

Communication and Team Fit Factors

When it comes to hiring mobile developers, technical expertise is only part of the equation. The ability to connect and collaborate within a team is just as critical. In fact, 92% of hiring managers believe soft skills are as important, if not more so, than hard skills. Yet, many companies fall into the trap of focusing solely on technical qualifications, overlooking the communication and teamwork abilities that often make or break a project.

Clear communication and teamwork are the glue that holds a team together. Misalignment on these fronts can have serious consequences. For example, 47% of federal hiring failures are due to poor team dynamics rather than skill gaps. In mobile development, where collaboration with designers, product managers, and stakeholders is essential, hiring someone who struggles to communicate effectively can derail progress.

Focus on Problem-Solving and Teamwork

Your job description should go beyond generic phrases like "strong problem-solving skills." Instead, paint a picture of the real challenges developers will face. Will they need to debug performance issues on outdated devices? Or resolve integration problems when third-party APIs suddenly change? These specifics help candidates understand the role and prepare for the realities of the job.

Good communication is key in these situations.

"If you can not effectively communicate with your team then the project will fail. PERIOD FULL STOP"

This underscores the need to hire developers who can explain technical problems to non-technical stakeholders or work closely with QA teams to squash bugs.

Another critical quality is empathy. Mobile developers must grasp the frustrations users feel when apps don’t function as expected. They need to turn user feedback into actionable technical improvements and collaborate with UX designers to create seamless, user-friendly interfaces. A survey shows that 75% of hiring managers value emotional intelligence (EQ) more than IQ, making EQ a must-have trait for mobile development roles.

Teamwork expectations should also be clearly defined. Will developers mentor junior colleagues, lead architecture discussions, or spearhead key technical initiatives? Highlighting these responsibilities helps candidates see how they’ll contribute to the team. After all, interdisciplinary collaboration boosts project success rates by 20%.

And don’t forget adaptability. Mobile development moves fast, with new tools and frameworks constantly emerging. Developers must be ready to embrace change, learn continuously, and adjust their technical strategies to keep up.

Address U.S. Business Practices

For developers working in the U.S. or with American companies, understanding workplace norms is essential. Your job description should touch on communication styles that align with U.S. business practices, such as direct feedback, structured meetings, and adherence to deadlines.

According to LinkedIn, 57% of business leaders value interpersonal skills alongside technical expertise. This means you should outline how developers will engage in activities like sprint planning, stakeholder presentations, and cross-departmental meetings. Will they need to present updates to executives? Join client calls or participate in user research? Be specific about these expectations.

If your team operates across time zones or works with international clients, make sure to clarify scheduling flexibility and time zone considerations. Clear communication about these logistical details can prevent misunderstandings.

Strong communication skills can also drive productivity. Teams that prioritize clear communication and active listening see productivity gains of up to 25%. This makes it important to highlight expectations for written communication through tools like Slack or email, verbal presentations during team discussions, and documentation standards that align with U.S. compliance requirements.

For leadership roles, cultural alignment becomes even more critical. While diversity in executive teams boosts performance – companies with diverse leadership are 36% more likely to outperform their peers – shared communication practices and work styles are essential for success. If the role involves leading projects or mentoring others, explain how candidates will navigate American management styles and team dynamics.

To assess cultural understanding, consider including scenarios in the hiring process. For instance, how would they handle disagreements in technical discussions? What’s their approach to work-life balance in a fast-paced startup? These questions not only help candidates evaluate their fit but also give you valuable insight into their adaptability and mindset.

Language Matters: Avoid Unclear Terms and Jargon

When it comes to job descriptions, the words you use can make or break your hiring process. Clear communication is essential, especially when you consider that 66% of young people struggle to understand the roles they’re applying for due to unclear job descriptions, and over one-third of postings include jargon, acronyms, or technical terms that discourage applicants.

This isn’t just about confusion – it’s about accessibility. With 20% of surveyed individuals expressing a dislike for corporate buzzwords and 71% of remote workers feeling excluded due to excessive business jargon, using plain language can give your organization a real edge. Clear communication not only helps candidates understand the role better but also improves recruitment outcomes.

"Understanding jargon is not a measure of a young person’s potential or indication that they are a better candidate. We’re concerned that the prevalence of ‘business speak’ in job adverts aimed at first jobbers is a major barrier that could inadvertently screen out young people without access to working role models and networks."

  • Grace Mehanna, Youth Employment Campaign Director, Business in the Community

The goal isn’t to oversimplify your requirements – it’s to make them understandable. John Salt, Group Sales Director at totaljobs, emphasizes this point:

"By including jargon in their jobs ads, employers can end up discouraging the very candidates they want to attract. Eliminating jargon can significantly boost recruiter success."

Use Clear and Specific Job Titles

A job title is often the first thing a candidate sees, so it needs to be straightforward and descriptive. Overly creative titles like "Mobile Code Ninja" or "App Development Rockstar" might sound fun, but they fail to convey the actual responsibilities of the role. Instead, opt for titles that clearly reflect the position and its requirements. For example:

  • "Senior iOS Developer" specifies the platform, experience level, and core function.
  • "Mobile Application Developer – React Native" highlights both the role and the primary technology stack.

Most candidates search for standard terms like "Android Developer" or "Mobile Software Engineer", so sticking to search-friendly titles ensures your posting reaches the right people.

Let’s compare two approaches:

Vague and Creative: "Mobile Innovation Specialist – Join Our Digital Transformation Journey"
Clear and Specific: "Senior Android Developer – E-commerce Applications"

The second title immediately tells candidates what the role involves – platform (Android), experience level (Senior), and industry focus (E-commerce) – making it easier for them to determine if they’re a match.

Write a Clear Job Summary

A well-written job summary connects your company’s mission to the role’s purpose, using language that’s easy to understand. Avoid buzzwords and vague descriptions that obscure what the job actually entails.

Here’s an example of how clarity can transform a job summary:

Before (Unclear and Wordy):
"We are looking for someone who will handle multiple tasks, work with various teams, and contribute to company projects."

After (Clear and Concise):
"We seek a Project Manager to:

  • Oversee cross-departmental projects from planning to completion
  • Coordinate with teams to ensure timely delivery
  • Enhance client satisfaction through consistent communication and results-driven strategies."

For technical roles like mobile developers, replace phrases like "synergize interdisciplinary units" with straightforward tasks such as "collaborate with cross-functional teams." Instead of saying "leverage modern mobile frameworks", specify, "build modern mobile applications using current frameworks." By describing the day-to-day responsibilities – whether it’s building new features, creating applications from scratch, or improving performance – you help candidates visualize the role and decide if it aligns with their career goals.

"Speak plainly and say what you mean. Just about any message – regardless of how difficult – can be delivered respectfully and professionally. Don’t hide behind words that sound impressive if they don’t clearly convey what needs to be said. Speak in a way that brings people in and helps connect them with you and your message."

  • Fern M. Hernberg, Managing Director of People Strategy at Brighter Strategies, LLC
