Top Kotlin Developer Jobs in 2025: Trends, Salaries, and Tips

Kotlin has confidently secured its place in the top three fastest-growing programming languages. If just a few years ago it was associated exclusively with Android development, by 2025 its scope of application has become much wider. We analyzed the job market and identified key areas where Kotlin developers are currently most in demand.

1. Android Developer (Kotlin) — The Classic Genre

Google officially declared Kotlin the priority language for Android, and in 2025 this is the standard. More than 70% of vacancies are still related to mobile development. Employers are looking for specialists proficient in Jetpack Compose, Coroutines, and MVVM/MVI architecture. Average salary in Russia: 250,000 – 450,000 RUB (in Moscow up to 600,000 RUB).

2. Backend Developer on Ktor and Spring Boot

Kotlin is actively replacing Java in the backend. The Ktor and Spring Boot frameworks with Kotlin support are in huge demand. Companies value code conciseness and null-safety. Knowledge of microservices, Docker, Kafka, and PostgreSQL is required. Salary: 300,000 – 500,000 RUB. Remote positions in international projects pay from $5,000/month.

3. Kotlin Multiplatform (KMP) Developer

KMP is the main trend of 2025. This technology allows writing shared code for Android, iOS, and the web. Vacancies are appearing in startups and large product companies. Knowledge of Swift, iOS SDK, and experience integrating with native platforms are needed. Salaries are 20–30% higher than those of regular Android developers: from 350,000 RUB.

4. Data Engineer / Kotlin for Data Processing

An unexpected but growing segment. Kotlin is used for writing pipelines in Apache Spark (via the Kotlin API) and creating ETL processes. Specialists with experience in Big Data and knowledge of Kotlin earn from 400,000 RUB and above.

5. Full-stack Developer (Kotlin + JS/TS)

With the advent of Kotlin/JS and Compose for Web, the demand for full-stack engineers who write both the server and client parts in one language is growing. Knowledge of React, TypeScript, and experience creating SPAs are required. Salaries: 300,000 – 550,000 RUB.

Key Skills for a Successful Job Search in 2025

Coroutines and Flow — a mandatory standard for asynchrony.
Jetpack Compose — for Android and Desktop (Compose Multiplatform).
Ktor and Spring Boot — for the backend.
Kotlin Multiplatform — as a competitive advantage.
Docker, Kubernetes, CI/CD — DevOps competencies increase salary.
English — most top vacancies require an Upper-Intermediate level and above.

Advice for Beginners

Don't limit yourself to just Android. Learn Ktor for the backend and KMP for cross-platform. In 2025, companies are looking for versatile specialists capable of working at multiple application levels.
