5 Best Practices When Shortlisting Kotlin Developers
Consider these 5 best practices when you shortlist candidates to find the best Kotlin developers.
a. Prioritize Industry-Specific Experience
A Kotlin developer with experience in your industry will adapt faster to project needs. If you’re building a fintech app, for example, look for candidates who have worked with banking APIs and security protocols. Review their past work for industry relevance rather than just their years of experience.
b. Assess Problem-Solving Through A Live Task
Instead of generic coding tests, give candidates a small, real-world problem related to your project. For example, ask them to refactor an inefficient Kotlin function or optimize an API call. This helps measure how they think, debug, and improve code under real conditions.
c. Verify Code Simplicity & Scalability In Previous Projects
Kotlin’s expressiveness allows for both concise and scalable code, but not all developers leverage it well. Request samples of their past projects or review their GitHub repositories. Look for clean, maintainable code that balances performance with readability.
d. Look For A Proactive Mindset & Continuous Learning
Kotlin evolves rapidly, and the best developers keep up with changes. Check if they contribute to open-source projects, write about Kotlin best practices, or engage in developer communities. A proactive developer will bring long-term value, not just short-term deliverables.
e. Make Sure They Can Communicate Technical Concepts Clearly
Strong Kotlin skills mean little if a developer can’t communicate solutions effectively. Ask them to explain a complex coding decision in simple terms during the interview. Collaboration with your team might become a challenge if they struggle to articulate their thought process.
Conclusion
You want to hire a Kotlin developer without turning the process into a time sink. Now you have these 17 platforms that offer Kotlin developers who not only write Kotlin but also architect scalable, high-performance applications—without the headaches of sifting through hundreds of resumes or rolling the dice on unverified candidates.
Genius takes it a step further with elite-level Kotlin developers. We offer a 12-step vetting process, on-the-ground recruitment teams, and access to the top 1% of talent in Latin America and the Philippines at 80% less cost than local hiring to all our clients.

FAQs
What industries commonly use Kotlin developers?
Kotlin developers are highly sought after in mobile app development, fintech, healthcare, SaaS, gaming, and IoT industries because of their efficiency and Android-native capabilities.
Do I need a full-time Kotlin developer, or can I hire on a contract basis?
It depends on your project scope. A full-time hire makes sense for long-term development. A contract-based or freelance developer may be more cost-effective for short-term fixes, maintenance, or MVP builds.
What is the difference between a Kotlin backend developer and an Android Kotlin developer?
An experienced Android developer develops Android mobile applications using Jetpack, Compose, Android SDK, and the Android ecosystem. A Kotlin backend developer works with frameworks like Ktor and Spring Boot for server-side development.
What security best practices should a Kotlin developer follow?
A skilled Kotlin developer should understand secure API handling, encryption protocols, authentication mechanisms like OAuth, and protection against SQL injection and data leaks.
