Hire Kotlin developers

Companies hire Kotlin developers because the Kotlin programming language is one of the most reliable options for Android and server-side development. The main reason is that Kotlin is both safe and expressive. It fixes Java’s problems while still working with existing Java code, so you can switch over gradually without starting from scratch. It’s officially supported by Google for Android and runs seamlessly on the JVM (Java Virtual Machine), making it perfect for building Android apps, REST APIs, or backend systems that require scalability and stability.

Kotlin’s concise syntax and active community help startups launch MVPs and new features faster. For enterprises, its static typing and null safety reduce crashes and maintenance costs. It also supports modern approaches like reactive programming and coroutines, enabling smooth, responsive user experiences.

Before deciding, we usually help our clients evaluate technical feasibility through short consultations. We analyze:

• their stack

• the scope of their project

• their long-term plans to confirm if Kotlin is the best fit

For most Android and JVM-based solutions, it’s not just a strong choice, it’s the most future-proof one.

You can hire Kotlin developers across multiple profiles: 

• Android-focused

• Backend

• Full-stack JVM engineers

When it comes to mobile app development, our developers bring deep experience with Jetpack Compose, Android SDK, Firebase, and Material Design principles to deliver high quality Android apps. They handle everything from performance optimization to implementing scalable architectures like MVVM or MVI. If you’re building on the backend, our Kotlin specialists are skilled in frameworks like Spring Boot or Ktor and can architect distributed systems, APIs, and microservices with ease.

Some of our clients prefer mixed Kotlin development teams where Kotlin developers work both on Android and server-side systems, ensuring faster iteration and fewer dependencies between departments. We can also provide Kotlin Multiplatform Mobile (KMM) specialists who build shared logic for both iOS and Android, cutting software development time without compromising app quality. This flexibility helps you adapt your team setup to the project’s lifecycle, and it doesn’t matter if you’re just starting out or scaling existing products.

Every candidate goes through both technical and HR screening before joining your shortlist. We evaluate their technical depth, communication style, and collaboration habits so that when you onboard someone, they already fit into your workflow. That’s how we make sure you don’t just hire a developer, but a team player ready to contribute immediately.

Definitely. Kotlin is now used widely for backend and cloud-native development. Our Kotlin backend engineers work with frameworks like Ktor and Spring Boot to build lightweight, high-performance services that scale efficiently. They can work on custom Kotlin app development, design APIs, manage databases, integrate queues like Kafka, and deploy on cloud providers such as AWS or GCP. 

We’ve helped clients build admin dashboards, SaaS platforms, and microservices using Kotlin, where stability and scalability were key. Our developers bring a good balance between backend structure and user-facing awareness, ensuring data flows seamlessly between layers. They pay special attention to performance bottlenecks, security best practices, and maintainable architecture.

Beyond coding, we provide architectural consulting and DevOps support when needed. This means your Kotlin developers can work alongside your existing backend team or take ownership of full modules. Whether it’s integrating APIs or modernizing old codebases, we’ll make sure your backend stays clean, efficient, and easy to maintain.

We support both and support a wide range of app development services.  If you need a developer for a quick refactor, we can connect you with someone available immediately. But if you’re looking for a long-term collaboration, we specialize in maintaining stable, ongoing relationships between clients and engineers. 

Long-term partnerships allow us to build continuity and protect your delivery process from disruption. We maintain open communication with both the developer and your management team, helping address potential issues early, before they impact delivery. Our HR and delivery specialists stay involved through regular feedback and performance check-ins to make sure your team continues to work smoothly.

We also support scaling your Kotlin team as your roadmap changes. When you need additional hands or senior-level support, we already have a clear understanding of your goals and processes, allowing us to add new members quickly without compromising the development process. 

Yes, and we’ve done this successfully for multiple clients. Migrating from Java to Kotlin is one of the best decisions you can make for your Android project, but it’s not an easy process. Our Kotlin developers have experience performing gradual migrations, starting by converting smaller, standalone modules before updating the whole codebase. This approach minimizes risks and keeps your app stable during the transition.

The main benefits of migrating are:

• cleaner code

• fewer runtime crashes

• easier maintenance

Kotlin cuts down boilerplate and works seamlessly with modern libraries like Jetpack Compose, Hilt, and Retrofit. We keep testing and CI/CD pipelines running smoothly during migration to ensure steady delivery and stability.

Before we start, we conduct a technical audit to identify dependencies, outdated libraries, and potential blockers. This lets us create a migration roadmap that fits your product timeline. Once the migration is complete, your team will have a more flexible, future-proof codebase that’s easier to maintain and extend.

Every developer we hire goes through a multi-step vetting process. It includes a technical interview, during which we check their skills in:

• Architecture

• Version control

• Tools like Git, Docker, and CI/CD 

All interviews are conducted by senior Kotlin engineers or our CTO to keep the process relevant and rigorous.

However, technical skill is just one part. We pay attention to soft skills, such as communication, reliability, and problem-solving approaches to find best Kotlin developers. Every candidate goes through an HR interview to assess how they collaborate, handle feedback, and adapt to new teams. 

Once hired, even skilled Kotlin developers continue to receive mentorship and regular evaluations from our technical leads. We provide ongoing performance reviews, training sessions, and education (relevant courses, individual development plans, etc.). This ensures that the people you hire don’t just meet today’s requirements, they keep growing as your project evolves.
