Tips For Hiring The Best Dedicated Kotlin Developers For Your Project

As end users' wants and aspirations change, so do information and technology. With so many programming languages on the horizon, we must consider our needs before employing a programmer. With the introduction of Kotlin, android app development has undergone a revolution. With Google becoming more Kotlin-oriented, most organizations want to build using only Kotlin. There are several reasons for this, including that Kotlin speeds up the production of legible, maintainable, and expressive code.

Furthermore, Kotlin's popularity has surged due to its breakneck speed and first-rate features such as multi-platform mobile support, more type-safe, brilliant casting, and higher order function, among other things that make Kotlin succinct. Kotlin is also the world's fourth most popular programming language. However, locating and hiring the correct Kotlin developer can be one of the most crucial and challenging tasks for most businesses because they will drive your Android projects.

What does a Kotlin developer do?

The responsibilities of an Android developer and a Kotlin developer are similar in nature. The significant distinction is that Kotlin developers spend most of their time producing business-critical Android applications with good backend integration, which is an important task. The following are some of the other primary responsibilities of a Kotlin Developer:

  • Analyze requirements, transform them into wireframes, and develop code. Work with APIs and data resources.
  • Write more expressive and concise code to create a great mobile app from the ground up.
  • Complete security measures implementation
  • Analyze and optimize app performance regularly.
  • Code re-testing to ensure error-free software and the most incredible user experience.
  • Identify and resolve problems to improve app performance.

How to hire the best Kotlin Developer

Consider Kotlin required skills

When recruiting professional Kotlin developers for your project, you must consider their Kotlin skills. Look for applicants who grasp key Kotlin concepts, including null safety, coroutines, lambdas, and extension functions. They should have experience writing robust and fast Kotlin code that uses the language's expressive syntax and functional programming features.

Furthermore, developers will be able to create maintainable and scalable Kotlin apps if they have a solid understanding of object-oriented and functional programming principles and knowledge of common design patterns. Assessing applicants' knowledge of Kotlin-specific tools, such as Gradle and Kotlin DSL, can help assure their ability to create and deploy Kotlin projects efficiently.

Excellent knowledge of Kotlin and Java

When recruiting specialized Kotlin developers for your project, ensure they are well-versed in Kotlin and Java. The ideal applicant should be well-versed in Kotlin syntax, features, best practices, and its interoperability with Java. Java proficiency is also significant since it allows developers to work smoothly with existing Java codebases and libraries. Look for developers who understand object-oriented programming, functional programming, and the Java Virtual Machine (JVM).

Furthermore, knowledge of popular Kotlin frameworks and libraries like Ktor, Spring Boot, and Retrofit can be beneficial. Assessing candidates' knowledge of Kotlin and Java via coding tests or studying past projects might help accurately measure their technical ability.

Experience with SQL and Linux

When hiring specialized Kotlin engineers for your project, it is critical to prioritize individuals with SQL and Linux knowledge. SQL (Structured Query Language) is a fundamental language for maintaining and manipulating relational databases, which makes it essential for backend development. SQL knowledge enables developers to connect with databases more efficiently and optimize data retrieval. Furthermore, knowledge of Linux, a widely used operating system, benefits server-side development and deployment.

Linux knowledge allows developers to configure servers, manage security, and use various tools and technologies typically used in Kotlin application development. Ensuring candidates' SQL and Linux experience will help your project's backend infrastructure succeed.

Check problem-solving abilities

Look for people who can display good analytical thinking and logical reasoning skills. A professional Kotlin developer should be able to deconstruct complex challenges into manageable components and offer efficient solutions. They should have a strong understanding of data structures and algorithms and prior expertise in efficiently solving coding issues. Examine their abilities to optimize code for efficiency and scalability and their knowledge of Kotlin-specific libraries and frameworks.

Additionally, assess their debugging and troubleshooting skills, which are critical for maintaining and increasing code quality. Candidates with a track record of handling complex problems and delivering sturdy solutions in Kotlin should be prioritized.

Review Experience And Projects

Look for applicants with relevant experience working with Kotlin and delivering Kotlin-based projects. Examine the scope and complexity of their previous projects to verify they can handle the demands of your project. Please take note of the technologies, frameworks, and libraries they've used, such as MVVM architecture, Coroutines, Dagger, or Room.

Additionally, consider their ability to optimize code, handle performance issues, and integrate third-party APIs. A thorough review of their experience and projects will provide valuable insights into their technical expertise and the quality of their work.

Conduct Thorough Interviews And Technical Assessments

During interviews, ask specific questions on language features, standard libraries, and best practices to delve into their Kotlin knowledge. Investigate their knowledge of Kotlin's compatibility with Java and their experience with JVM internals and memory management. Consider coding challenges that test their ability to write clean and efficient Kotlin code to measure technical skills.

Pairing programming tasks also allows you to observe their problem-solving methodology, code readability, and teamwork skills. By following these steps, you can ensure that the developers you choose have the technical skills to succeed in your Kotlin project.

Clearly Define Your Project Requirements

This includes establishing your project's scope, objectives, and technical specifications. A detailed project description assists potential applicants in understanding the exact skills and experience needed. It's critical to specify whether you require knowledge of specific Kotlin frameworks or libraries, such as Ktor or Room. Furthermore, mentioning any linkages with Java or other technologies can aid in attracting developers with relevant skills. You may successfully explain your expectations and ensure that the candidates you evaluate correspond with the unique demands of your project by clearly describing your project criteria.

Ensure They can Write Clean Code.

Clean code is critical for your project's long-term maintainability and scalability. Look for developers who stick to naming conventions, produce modular and reusable code, and are concerned with code readability. Examine their knowledge of solid principles, design patterns, and clean architecture concepts. Consider candidates familiar with tools such as Kotlin Lint or Detekt, which can assist in enforcing code quality standards. A developer who regularly writes clean, well-structured code can help your project's overall efficiency and success.


Hiring the best dedicated Kotlin developers requires a thorough evaluation of their Kotlin and Java knowledge, problem-solving abilities, experience with relevant frameworks and libraries, and communication skills. Technical assessments and interviews are vital in assessing their proficiency and suitability for your project's requirements and technical demands. By following the above-mentioned steps, you can make sure that the Kotlin Developer you hire is going to be an asset rather than a liability.
