A Kotlin Developer designs, builds, tests, and maintains software where Kotlin is a primary programming language.
Many Kotlin Developers specialize in Android, although the language is also used for JVM backends and Kotlin Multiplatform products.
Typical Kotlin Developer responsibilities can include:
The exact scope depends heavily on the position.
An Android-focused Kotlin Developer might work primarily with:
A multiplatform developer might work more heavily with:
A backend Kotlin Developer may instead work with:
Make the specialization explicit before you start screening candidates.
A dedicated Kotlin Developer becomes particularly valuable when Kotlin already sits at the center of your mobile, backend, or multiplatform architecture.
Kotlin is widely used across modern Android development.
A developer with direct Android experience can work across:
A growing mobile roadmap may include:
A dedicated Kotlin Developer can expand your native-development capacity.
Many established Android applications contain Java alongside newer Kotlin modules.
An experienced Kotlin Developer can migrate code incrementally while maintaining interoperability with existing Java functionality.
Older Android applications may rely heavily on XML layouts and Views.
A developer comfortable with both approaches can introduce Compose gradually instead of requiring the entire UI to be rewritten.
Mobile applications regularly coordinate:
A Kotlin Developer experienced with coroutines and Flow can help structure that work more safely.
If your iOS and Android teams repeatedly implement the same:
Kotlin Multiplatform may allow selected functionality to be shared.
A developer with genuine KMP production experience can help determine which code is worth sharing.
Companies already invested in JVM infrastructure may choose Kotlin for backend services.
A Kotlin Developer with Spring Boot or Ktor experience can build APIs while retaining access to Java libraries and infrastructure.
Performance issues may involve:
A strong Android-focused Kotlin Developer should profile the application before making optimization decisions.
Mobile applications have more lifecycle complexity than ordinary backend systems.
Poor lifecycle handling can create:
Someone experienced with modern Android architecture can help reduce those problems.
The qualifications should match whether you're hiring for Android, multiplatform, or backend development.
Several Kotlin fundamentals matter across all three.
Candidates should understand:
Candidates should understand:
Ask them to explain how coroutines actually change execution rather than simply listing coroutine builders.
For reactive or Android roles, experience with:
can be particularly useful.
Candidates should understand when a continuous stream is more appropriate than a one-time suspending function.
Many Kotlin applications still interact with substantial Java code and libraries.
Candidates should be comfortable moving between both languages where required.
For Android positions, evaluate:
Modern Android roles increasingly require Compose.
Look for experience with:
Don't remove traditional Android UI experience from the requirements if your existing application still contains substantial XML or Fragment-based architecture.
Relevant Android experience may include:
Backend Kotlin positions may use different dependency-injection patterns.
Candidates should be comfortable with:
Tools may include Retrofit or Ktor.
Android positions may require:
Multiplatform applications may use technologies such as SQLDelight.
If your role involves KMP, evaluate actual production experience with:
Don't treat ordinary Android Kotlin experience as equivalent to deep Multiplatform expertise.
For backend positions, match framework requirements directly.
Spring Boot fits many established JVM organizations.
Ktor provides a Kotlin-oriented asynchronous framework.
Candidates may need experience with:
Kotlin projects rely heavily on Gradle.
Candidates should be comfortable working with build files, plugins, dependencies, and multi-module structures.
Relevant experience may include:
Look for someone who can explain why a pattern improves the product rather than applying architecture mechanically.
Senior Android candidates should understand how to investigate:
Candidates should be comfortable with pull requests, code review, build automation, and release pipelines.
Kotlin Developers often collaborate with:
Strong communication helps keep behavior consistent across platforms and services.
Kotlin Developer compensation depends on seniority, Android experience, Kotlin Multiplatform depth, backend specialization, and the complexity of the product.
South's current Kotlin Developer page lists an average U.S. salary of approximately $10,600 per month and an average Latin American salary of approximately $3,800 per month.
That's potential savings of around 64%.
The exact cost will depend on the profile you need.
Junior Kotlin Developers can contribute to:
They work best when experienced engineers provide architectural guidance and code review.
Mid-level developers can generally own complete product features.
They may handle:
Senior developers can own broader technical decisions.
They may:
KMP specialists may take ownership of:
This is a more specialized profile than a standard Android Kotlin Developer.
Backend specialists may require:
Make the backend scope explicit because many Kotlin résumés are primarily Android-focused.
A Kotlin Developer interview should test language fundamentals, coroutines, architecture, testing, debugging, and the platform the person will actually work on.
An Android interview and a backend Kotlin interview shouldn't be identical.
Ask:
Walk me through the most complex Kotlin application you've worked on.
Then ask:
Ask:
What's the difference between String and String?, and how do you avoid turning nullable code into a collection of !! operators?
Strong candidates should talk about modeling nullability intentionally.
Ask:
How would you represent a screen that can be loading, loaded with data, empty, or failed?
Sealed classes or interfaces may provide a clean model.
Ask:
A screen needs data from three independent APIs. How would you structure the requests?
Look for understanding of:
Ask:
The user leaves a screen while its API request is still running. What should happen?
For Android positions, this can reveal understanding of lifecycle-aware scopes.
Ask:
When would you return a Flow instead of a suspend function?
Strong candidates should distinguish one-time results from values that change over time.
For an Android position, ask:
Where would you keep screen state during configuration changes?
Look for modern architecture awareness.
Ask:
A Compose screen keeps recomposing more often than expected. How would you investigate it?
Candidates may discuss:
Ask:
How would you introduce Kotlin into a large existing Java project?
Look for incremental migration rather than an unnecessary rewrite.
For KMP positions, ask:
Which parts of a mobile application would you share between Android and iOS, and which would you keep platform-specific?
Good candidates should treat code sharing as an architecture decision rather than a goal of 100%.
For backend positions, ask:
Why would you choose Kotlin over Java for an existing Spring Boot environment?
Strong candidates should discuss interoperability, developer experience, type safety, coroutines where relevant, and team expertise.
Useful questions include:
Choose questions based on the role.
An Android Developer, KMP specialist, and Kotlin Spring Boot Developer need different technical interviews.
These roles overlap heavily.
An Android Developer specializes specifically in Android.
Their expertise may include:
A Kotlin Developer is defined more broadly by the programming language.
They may work across:
If you're specifically building a native Android application, Android Developer may describe the requirement more precisely.
If the person needs to work across several Kotlin targets, Kotlin Developer may fit better.
A Java Developer specializes in Java and the wider JVM ecosystem.
A Kotlin Developer uses a language that interoperates closely with Java but adds features such as:
Companies with existing JVM products may use both languages within the same codebase.
A Swift Developer typically works across Apple's development ecosystem.
Kotlin Developers frequently work across Android.
For a fully native mobile team, a company may hire both roles:
Kotlin Developer → Android
Swift Developer → iOS
Kotlin Multiplatform can also allow selected code to be shared between those applications.
A Kotlin Developer may build native Android applications or Kotlin Multiplatform products.
A Flutter Developer uses Flutter and Dart to create cross-platform applications.
Hire according to the mobile architecture your company has already chosen rather than selecting based solely on how much code can theoretically be shared.

Android, backend, or Kotlin Multiplatform requirements should match the actual role.
Only when the position involves Android.
Kotlin is also used for backend, multiplatform, desktop, web, and other software-development workloads.
Deep Java expertise isn't mandatory for every Kotlin position, but practical Java interoperability experience is valuable in many JVM and Android codebases.
Kotlin Multiplatform developers work with shared Kotlin code that targets several platforms.
For mobile products, that often involves sharing business logic between Android and iOS while preserving platform-specific functionality where required.
Android Developer is a platform-specific role.
Kotlin Developer is language-focused and may work across Android, JVM, backend, or multiplatform environments.
Consider hiring one when Kotlin is central to your Android or JVM stack, you're modernizing Java code, adopting Jetpack Compose, introducing Kotlin Multiplatform, or building backend applications with Kotlin.
Yes. Latin America has Kotlin Developers with experience across Android, Jetpack Compose, coroutines, Kotlin Multiplatform, Java, Ktor, Spring Boot, Room, Retrofit, and modern application architecture, with working hours that can align closely with U.S. teams.

The region has the perfect mix of everything you want in remote employees: English skills, shared time zones, hard-working, and depth of talent. They are already accustomed to working remotely for top US startups and Fortune 500 companies.
Absolutely! The US and Latin America have basically the same time zones. No Latin American city is more than two hours ahead of EST.
Every hire is sourced based on your exact needs. They will arrive ready to support your business right away. They can do basically any tasks done remotely, but we recommend starting them as support so your team has more bandwidth for high-value strategic tasks.
All types of roles - customer service, executive assistant, sales, accounting, email marketing, lead generation, content writers, operations, social media marketing, and more!
You can pay directly through us (most popular) or we can connect you with one of our payroll partners.
You don't have to deal with any American labor laws / taxes when hiring full-time remote contractors. They aren't US-based, so no visas or sponsorships to deal with either.
Pricing is one flat monthly rate per hire. The rate includes your teammate's compensation and South's service in a single consolidated invoice. It covers sourcing, vetting, payroll, compliance, ongoing support, and a free replacement if you ever need one. Rates vary by role and seniority. See our savings by role page for typical ranges, then we'll confirm an exact rate for your role.
There are no cancellation fees or minimum commitments, and you only pay if you make a hire.
Yes, we only recruit for full-time and we strongly recommend full-time hiring if you can. Stability (full-time & long-term) is highly sought after abroad. The top caliber candidates are only looking for full-time work.
You're also going to spend time training and getting them up to speed on your processes. It would be a waste to do that over and over again with new people all the time.
We recommend training new hires on one thing at a time.
For example, once they get up to speed on lead generation, you can add the next role writing blog posts or whatever you'd like. You can definitely overlap roles until you have enough work for multiple people.
The cost of living is much less in Latin American countries. Many of our employees are able to own homes, raise families, provide for their parents, and have in-home help of their own with their salaries.
If you aren't happy with your hire in the first 120 days, we will work with you to conduct a second round of search for the same role for free.
