Remote Kotlin Developer Jobs

Kotlin is a modern, statically typed programming language that combines object-oriented and functional features into one powerful tool. It can be used for developing applications for Android, web, desktop, and server environments.

As Kotlin continues to gain popularity, the demand for developers with Kotlin skills has increased. Kotlin jobs can range from mobile app development to server-side development, and many companies are actively seeking remote Kotlin developers with experience.

With its growing popularity among the tech community, the demand for experienced Kotlin developers has seen an uptick over recent years. This makes it a great opportunity for those looking to get into freelance or remote work as a developer in this field.

Skills Needed For Kotlin Jobs

Technical Skills:

Some of the critical technical skills needed for Kotlin jobs include:

Kotlin Programming

Proficiency in writing Kotlin code, including object-oriented and functional programming concepts, data structures, algorithms, and design patterns.

Android Development:

Experience developing mobile applications for Android using Kotlin, including knowledge of Android SDK, Android Studio, and Android development best practices.

Web Development

Experience developing server-side applications using Kotlin, including knowledge of web frameworks such as Spring Boot, Ktor, or Vert. x.

Familiarity with Java

Kotlin is interoperable with Java, so familiarity with Java syntax and Java libraries is essential for Kotlin developers.

Debugging and testing

Experience with debugging techniques, testing frameworks such as JUnit or Mockito, and continuous integration and deployment tools like Jenkins or Travis CI.

Git and version control

Proficiency in using Git for version control and collaboration with other developers.

Database management

Familiarity with SQL and experience working with databases, such as MySQL, PostgreSQL, or MongoDB.

Familiarity with software engineering principles

If you're a software engineer and you know about principles and practices such as Scrum, Kanban, your chances to land a remote Kotlin job are much higher.

Soft Skills

Here are some of the vital soft skills that are valuable for Kotlin developers:

Communication skills

Communicating effectively with team members, stakeholders, and customers. This includes active listening, clear and concise verbal and written communication, and conveying technical information to non-technical stakeholders.


Identifying problems, analyzing data, and developing practical solutions. Kotlin developers should be able to think creatively and approach issues from different angles to find the best solution.


The ability to adapt to changing technologies, project requirements, and work environments. Kotlin developers should be able to work in an agile and fast-paced environment and be open to learning new tools and technologies.


Kotlin developers should be able to collaborate with team members, share knowledge, and contribute to the team's success.

Time Management skills

Managing time effectively and prioritizing tasks based on project deadlines and requirements.

Specialized Skills

Here are some examples of specialized skills that may be required for Kotlin jobs:

Android SDK

Knowledge of Android SDK and Android development best practices is critical for mobile app developers. This includes familiarity with Android architecture components, Material Design guidelines, and performance optimization techniques.

Spring Boot

For server-side developers, familiarity with Spring Boot is essential. This includes knowledge of Spring Boot's core features, such as dependency injection, configuration, and data access.

Reactive Programming

For developers working with asynchronous applications or high-throughput systems, familiarity with reactive programming frameworks like RxJava or Reactor may be necessary.

Test-driven Development

Some Kotlin job roles may require experience with test-driven development (TDD) or behavior-driven development (BDD), including knowledge of testing frameworks like JUnit, Mockito, or Cucumber.

Domain-driven Design

Familiarity with domain-driven design (DDD) principles may be valuable for developers working on complex projects. This includes knowledge of DDD concepts such as bounded contexts, aggregates, and entities.

Cloud Technologies

For developers working on cloud-based applications, knowledge of cloud technologies such as AWS, Azure, or GCP may be necessary. This includes an understanding of cloud architecture, serverless computing, and containerization.


Knowledge of best security practices and standards is essential for developers working on sensitive data applications. This includes familiarity with authentication and authorization mechanisms, encryption, and secure coding practices.

Specialized skills may vary depending on the specific Kotlin job role and industry, but having expertise in these areas can make a Kotlin developer more valuable to potential employers.

Top 5 Interview Questions for Kotlin Developer

Explain the difference between val and var in Kotlin?

The question of the difference between val and var in Kotlin is important because it is a fundamental concept in the language and understanding it is crucial for writing correct and efficient Kotlin code.

The ideal answer should explain that val declares an immutable variable, while var declares a mutable variable, and provide an example of each.

Explain the concept of data classes in Kotlin?

Data classes in Kotlin are used to represent simple, immutable data models. The candidate should be able to discuss the benefits of using data classes, such as auto-generated equals(), hashCode(), and toString() methods, as well as the copy() function. They should also be aware of when and how to use data classes effectively.

What is a sealed class in Kotlin & how can it be useful in practice?

The question of what a sealed class is in Kotlin and how it can be useful is important because sealed classes are a unique and powerful feature of the language that can be used to enforce data modeling constraints and improve code safety.

A strong answer should explain that a sealed class is a class that a fixed set of classes can only extend, and that this can be useful for creating data models or state machines with a finite number of possible states.

How does Kotlin support coroutines?

This question is important to ask since coroutines are a powerful feature in Kotlin that enables asynchronous programming.

The candidate should be able to explain the basic concepts of coroutines, including suspending functions, launch vs. async, and how to handle exceptions in coroutines. A strong candidate will also be familiar with the various coroutine scopes and context.

Can you explain how the lateinit keyword works in Kotlin, and when it should be used?

The question of how the lateinit keyword works in Kotlin and when it should be used is important because it is a unique feature of the language that can help improve code efficiency and flexibility.

A good answer should explain that lateinit is used to declare a non-null variable that can be assigned a value later, and that it should be used sparingly and only when you know for sure that the variable will be initialized before it is used.
