How do we hire mobile app developers

1. Initial evaluation

The process begins with a thorough examination of the applicant’s resume to assess their qualifications and experience. Then, we invite the selected candidates to an online interview with one of our HR specialists, who will provide a detailed overview of the company and the position. Our prescreening process helps us identify talented developers who are experts in mobile app development and possess corresponding soft skills.

2. English proficiency assessment

The second step of the candidate app developer for hire is to pass the English language evaluation test that aims to assess their speaking skills and grammar knowledge. Our professional in-house English teachers check the candidate’s ability to clearly convey complex ideas to ensure they have strong language skills to communicate effectively with our clients.

3. Technical interview

Our goal is to identify top-tier candidates and hire an application developer with the technical skills and expertise to excel in their roles. That’s why we engage the experts in their respective domains - senior developers, project managers, and team leads - to conduct tech interviews and assess each candidate’s technical knowledge and problem-solving skills. We apply theoretical and practical tasks to accurately evaluate the developer’s capabilities and choose the most qualified talents.

Where can I find and hire app developer?

Finding the right app programmers for hire depends on your project’s requirements and size. Here are three types of developers and where you can find them:

  • Freelance app developers might be a perfect fit for small projects. Go to Upwork, Freelancer, Codementor, or Toptal - the most popular platforms where you can find specialists with different levels of expertise and varying rates. They offer cost-efficient and flexible solutions but may lack long-term commitment and involve increased managerial overhead. 
  • Remote Employees are ideal for medium to long-term projects. They provide long-term commitment and retain expertise within your company but may involve hiring challenges and productivity assessments.  The best websites to find them include Remote.com, Hired, and YouTeam. 
  • Outsourcing companies and agencies. For complex projects, consider partnering with IT outsourcing companies or app development agencies like Relevant Software. They offer access to experienced teams of tech specialists tailored to your project's needs. 
Where can I find a mobile app developer for hire?

Freelancers, remote employees, or IT outsourcing companies? It depends. Below, we’ll explain in what case each type of mobile app developers for hire might work best, and will give a list of websites where to look for them.


If you have a small project that doesn’t need an app development team, designers, and testers (like creating a WordPress website), finding a freelance developer will be enough.

Upwork and Freelancer are the most popular platforms for hiring mobile app developers. Both Upwork and Freelancer function as liaisons between freelancers and employers, processing all the payments and protecting both parties from possible fraud.

Codementor is a commercial IT tutoring platform, connecting engineering mentors and mentees. It’s a go-to website if you want to find experts in a particular field to help you acquire new skills. Codementor will also match you with independent contractors if you need to have a small project or assignment done.

Pros of choosing freelancers:

  • Hiring freelancers is often the most cost-efficient way to gain access to a worldwide base of knowledge and skills.
  • You don’t have to pay for workplace appliances, perks, and benefits, etc. — you only pay for the job itself.
  • There are fewer responsibilities as an employer; once the project is delivered, the work relationship is either ended or paused until you collaborate on some project in the future.

Cons of choosing freelance developers:

  • The managerial overhead of keeping track of multiple tasks done by separate contractors.
  • Potential data security issues created by providing complete outsiders with access to mission-critical systems.
  • Unless they are long-term partners deeply engaged in the company events and strategy, freelancers are less personally invested in the long-term success of your endeavor due to the temporary nature of their employment.

Remote employees

When it comes to medium- and long-term projects that require specific training, consider hiring a remote employee. An RE is more like an extension to your team, rather than an independent player.

Places to find remote employees:

Of course, you can hire a mobile app developer on your own, using LinkedIn, for example. But you’ll have to weed out candidates who are not currently looking for a job or those who seek office-based positions. Instead, consider platforms specializing in remote mobile app developers for hire, such as Remote.com, Hired, and YouTeam.

Remote.com is a go-to platform for finding full-time and part-time remote contractors from around the globe. On Remote, you can either search for candidates manually or rely on the AI algorithm that finds the best talent based on the project duration, skills, and the payment model.

On Hired, you can find both freelancers and full-time mobile app developers for hire. The platform is industry- and location-specific (some regions of the US, Canada, and France). With a 5% admission rate, Hired accepts only IT talents with degrees from leading universities and backgrounds in leading companies (Facebook, Apple, etc.). At Hired, you can also hire a mobile app developer from your city.

YouTeam connects individual mobile app developers for hire from agencies and clients. All agencies and their developers have to pass a thorough screening and will be banned if their skills differ from what they advertise. If you need a team of developers, YouTeam is an ideal option. The platform offers multiple teams working in the same office and used to collaboration.

Gun.io utilizes their own network of high-quality independent developers to tackle any software engagement — whether it requires a few hours of work from a senior engineer — or the combined year-long efforts of an entire engineering team. Gun.io only accepts fully vetted developers who have passed their technical assessments, and collected endorsements from previous colleagues to verify their skill and seniority. They present candidates based on your project specifications and set up interviews with candidates you like best. Book your freelancer for the monthly hours that you need, and swap talent as your roadmap requires.

Pros of choosing to work with remote teams:

  • You form productive and engaged teams ready for a long-term commitment.
  • The expertise gained during the project stays within the company.
  • Employees working remotely often cost less, as they don’t require office expenses and other benefits.

Cons of choosing to work with remote teams:

  • It involves all the pains and hurdles of hiring employees and forming teams out of them.
  • If they fall ill, go on vacation, or quit, corresponding parts of your project are halted.
  • It can be difficult to accurately review developers’ performance and productivity.
  • Outsourcing companies and agencies

If you have a complex project, consider an IT outsourcing company or an app development agency. This gives you the privilege of hiring mobile app developers with a unique experience of work on top projects. It also guarantees that the deadlines will be met, the quality will shoot off the charts, and the management headache won’t be yours.

For example, Relevant Software offers mobile app developers for hire, as well as UI/UX designers, business analysts, security specialists, project managers, and QA experts. Having provided 200+ effective solutions, we are proud to be listed as one of the top software development companies, according to Clutch and GoodFirms.

Pros of outstaffing/outsourcing:

  • Instant access to ready teams possessing the needed expertise.
  • Ready solutions to minimize time-to-value for your projects.
  • The technology vendor takes care of the team’s motivation, perks, benefits, and replacement if need be.

Cons of outstaffing/outsourcing:

  • You might experience management difficulties.
  • Cultural differences may set teams apart.
How to hire an app developer?

  • Assess developers based on their skills, experience, portfolio, and client testimonials
  • Interview shortlisted developers and discuss budget, timeline, and communication preferences
  • Select the best fit and start collaboration.
How much does it cost to hire an app developer from an agency?

The cost of hiring an app developer from an agency varies based on factors such as location, expertise, project complexity, and required services. Rates can range from $30 to $150 per hour or more. To estimate the total cost, consider development hours, additional services (e.g., design, testing, deployment), and ongoing maintenance. Research multiple agencies, compare their offerings, and request a custom quote to find a partner that aligns with your budget without compromising quality.
