Kotlin Developer Salaries Rose by 20%: Market Analytics 2025

Kotlin Developer Salaries Rose by 20%: What's Behind This Growth?

The labor market for Kotlin developers continues to show impressive dynamics. According to the latest data from the analytical service Habr Career and job aggregators, the median salary of Kotlin specialists in Russia has increased by 20% over the past year, reaching 250,000–280,000 rubles for Middle level and above. This is one of the highest growth rates among all programming languages in 2025.

Key Figures and Trends

Analysts attribute this surge to several key factors:

• Active adoption of Kotlin in backend. Kotlin has long ceased to be a "language for Android only." Large companies (including banks and fintech startups) are actively migrating their microservices to Kotlin, valuing its conciseness and safety compared to Java.
• Shortage of talent. The number of vacancies for Kotlin developers has grown by 35%, while resumes have grown by only 10%. The market is in dire need of specialists, especially in the Senior and Team Lead segments.
• Corporate projects. The financial sector, e-commerce, and telecom are actively rewriting legacy code from Java to Kotlin, offering higher rates for this.

Regional Differences

The salary growth has affected not only Moscow and St. Petersburg. In the regions (Novosibirsk, Kazan, Yekaterinburg), Kotlin developer salaries have increased by an average of 15-18%. However, the median difference between the capitals and the regions is still about 70,000–80,000 rubles in favor of Moscow.

Interestingly, for Junior Kotlin developers, starting salaries have risen to 80,000–100,000 rubles, which is 25% higher than a year ago. This makes Kotlin one of the most attractive languages for entering the profession.

What Do You Need to Know to Qualify for a High Salary?

Employers are willing to pay above market rates if the candidate possesses the following skills:

• Kotlin Coroutines and Flow — a mandatory standard for asynchronous programming.
• Ktor or Spring Boot — backend frameworks.
• Kotlin Multiplatform Mobile (KMM) — cross-platform development experience increases the salary offer by 10-15%.
• Knowledge of Java — for working on hybrid projects (Kotlin + Java).
• Docker and Kubernetes — for Senior positions and above.

Forecasts for the Next Six Months

Experts expect the growth trend to continue. Kotlin is actively replacing Java in Android development (over 95% of new projects are already written in Kotlin) and is gaining momentum in backend. If you are planning to change your tech stack or start a career in IT, Kotlin is one of the most promising options in terms of income.
