Tips for Hiring Kotlin developers


Kotlin developers are at the forefront of modern Android development. This language takes the robustness of Java and combines it with a concise syntax that boosts productivity and reduces the potential for error. By choosing Kotlin for mobile and server-side applications, businesses leverage technology endorsed by Google. As a preferred language for Android, it ensures future-proof, cutting-edge development.

The rise of Kotlin is a response to the need for more streamlined, safer codebases that facilitate both development velocity and maintainability. The adoption of Kotlin often propels a company forward by enabling faster time-to-market for mobile applications.

Despite Kotlin's rapidly growing popularity, finding experienced developers is a difficult hurdle, as it is a relatively new language. This scarcity poses a challenge for businesses eager to capitalize on the efficiency and safety Kotlin offers. Companies must, therefore, be strategic in their search to hire Kotlin developers who not only understand the language's potential but also translate the potential into competitive and forward-thinking solutions.

Navigating this tight talent market calls for a strategic approach to attract and retain professional Kotlin developers who truly leverage the language's capabilities.

What Is Kotlin Development?

Kotlin was released in 2016 as a Java alternative. As an open-source, cross-platform, and general-purpose language, Kotlin is highly flexible and can be used on Windows, Linux, or Mac environments.

Although it’s relatively new, Kotlin is one of the fastest-growing languages. In 2017, Google announced it was an official language of Android development. Some well-known apps developed with or migrated to Kotlin are Coursera, Evernote, and Pinterest.

Java remains popular in Android development, but due to Kotlin’s more modern functionality and concise syntax, it’s a popular choice for app development. Additionally, Kotlin's advanced characteristics, like null safety and extension functions, make it ideal for businesses looking for robust app development with reduced chances of bugs.

Why Kotlin Development?

At the heart of any successful tech organization is a strategic selection of programming languages, and Kotlin has emerged as an increasingly popular choice. This statically typed language was designed with practicality in mind, providing a combination of both object-oriented and functional programming features. It ensures reliable and type-safe code, which significantly reduces application crashes and system failures, thereby improving user experience.

From a business perspective, Kotlin paves the way for faster product development without compromising quality or performance. The language's clear syntax and simplicity translate to less code, which means less room for errors and reduced time spent on debugging. For businesses seeking to leverage technology to gain competitive advantage or enhance operational efficiency, adopting Kotlin development could be a vital step forward.

Benefits of Kotlin Development

Kotlin development offers a compelling blend of efficiency, interoperability, and robustness. The unique features of this cutting-edge technology significantly enhances the software development process. Here are some of the main benefits of Kotlin development:

  • Interoperability with Java: The general compatibility between Kotlin and Java is a standout benefit. This allows developers to migrate gradually from Java to Kotlin, minimizing disruption during the transition.
  • Reduced boilerplate code: One of the pain points in software development is the creation and management of boilerplate code. Kotlin has been designed with a focus on reducing such redundancies, resulting in cleaner and more maintainable code.
  • Enhanced safety measures: Kotlin's design includes built-in null safety measures that minimize common programming errors, thus increasing application stability.
  • Support for functional programming: Kotlin supports functional programming paradigms alongside object-oriented features. This provides developers with flexibility when choosing the best approach for their project.

What Does a Kotlin Developer Do?

Kotlin developers bring a special blend of expertise to the table, specializing in a language designed for interoperability and modern features. Their skills are essential for creating seamlessly integrated, concise, and safe Android applications.

Kotlin programmers have a range of responsibilities related to developing, maintaining, and updating Kotlin applications — particularly Android apps with solid background integration. On any given day, a Kotlin developer may:

  • Design and develop Android apps using Kotlin
  • Use wireframes from designers to build code that conforms to project requirements
  • Find and fix bugs in existing code
  • Optimize the performance of apps built on Java and Kotlin
  • Integrate apps with appropriate APIs and data sources
  • Learn and integrate new technologies into the development process
  • Evaluate and maintain code quality and usability
  • Conduct unit testing to ensure high-performing, bug-free, dependable code

Required Skills and Qualifications

When hiring Kotlin developers, certain skills and qualifications are key. Naturally, a deep understanding of the Kotlin language, including concepts such as null safety, coroutines for asynchronous programming, and extension functions is crucial. Familiarity with frameworks like Ktor for building connected systems should also be considered.

Technical proficiency in Java is often useful due to its interoperability with Kotlin. Similarly, experience in Android app development is beneficial. Kotlin developers should have experience with Android Studio IDE, or other mobile development IDEs as necessary, and the Android SDK.

Knowledge of object-oriented programming (OOP) principles and design patterns is important for crafting functional code. On the non-technical side, good communication skills prepare developers to effectively collaborate with team members and explain complex concepts to non-technical stakeholders.

A degree in computer science or a related field provides foundational knowledge but isn't always necessary due to today's vast learning resources. Instead, a strong portfolio and a proven track record delivering software projects using Kotlin often outweighs formal education.

Popular Kotlin Related Languages and Libraries

Kotlin is a versatile language that shares similarities and interoperability with a variety of other languages. Developers who are fluent in these related languages further are able to enhance app security, efficiency, and performance. There are also numerous libraries that extend Kotlin's functionalities and make the development process more productive.

Related Languages

Kotlin's versatility is enhanced when developers have a grasp of complementary languages that enrich its utility in diverse development environments. Here are some popular related languages:

  • Java: As a statically typed language designed to run on the Java Virtual Machine (JVM), Kotlin shares many features with Java, but offers more concise syntax and additional safety features.
  • Scala: Like Kotlin, Scala is also interoperable with Java and runs on the JVM. However, Scala leans more heavily into functional programming concepts.
  • Groovy: Groovy is another JVM language that has similarities with Kotlin. It emphasizes scripting and ease of use but lacks some of Kotlin's safety features.

Related Libraries

A suite of dedicated libraries elevates Kotlin's effectiveness, equipping developers with tools to produce more robust and versatile applications. Libraries that complement Kotlin include:

  • Ktor: This is a lightweight framework for building asynchronous servers and clients in connected systems. Ktor allows the creation of web applications using idiomatic Kotlin in an easy-to-understand manner.
  • Spring Boot: This popular library facilitates building standalone Java applications swiftly. With Spring Boot providing support for Kotlin alongside Java, developers effectively leverage its quick startup capabilities combined with less boilerplate code.
  • Jetpack Compose: This library is mainly utilized for developing native UIs in Android projects using Kotlin. Jetpack Compose takes advantage of the declarative programming model offered by modern UI frameworks, making UI development more productive.

Understanding these related languages and libraries helps teams better grasp the versatility of Kotlin in different development scenarios.

Popular Kotlin Programming Tools

Kotlin developers have access to a variety of sophisticated tools that streamline the coding process, enhance productivity, and improve code quality.
