At JetBrains, code is our passion. Ever since we started, back in 2000, we have strived to make the strongest, most effective developer tools on earth. By automating routine checks and corrections, our tools speed up production, freeing developers to grow, discover, and create.

We’re now looking for a Customer Success Engineer (CSE) to help engineering teams successfully adopt Kotlin on the backend in real-world production environments.

Currently, this role is focused on adoption – helping Java teams introduce Kotlin into existing applications. You’ll work directly with organizations to guide migration, integration, troubleshooting, and scaling, ensuring they move from initial experiments to successful production use.

In addition, you’ll proactively communicate with prospective users to help them understand the Kotlin adoption process, as well as design and implement the migration path. 

• Track and maintain visibility into organizations and their stage of Kotlin adoption (e.g., not started, evaluating, experimenting, production)
• Proactively engage with organizations across different phases of their Kotlin adoption journey
• Develop and recommend high-level adoption strategies tailored to each organization’s context
• Identify and document blockers that hinder progress and propose ways to address them
• Establish and manage feedback loops with development teams to ensure continuous alignment and improvement

Technical expertise

• Extensive hands-on experience with Kotlin, Java, and the JVM ecosystem
• Proven experience migrating Java backend codebases to Kotlin
• Experience with the Spring (Boot) ecosystem or similar frameworks (e.g., Quarkus, Micronaut, Ktor)
• Solid understanding of build tools and project structuring, including Maven and Gradle

Communication and customer engagement

• Experience in customer-facing technical roles such as Solutions Engineering, Developer Advocacy, or Technical Consulting
• Strong English communication skills, both written and spoken
• Ability to lead workshops, demos, talks, meetups, and other public-facing activities
• Comfort with outbound engagement, including identifying target companies, articulating value propositions, and building relationships with engineering teams
• Ability to effectively communicate with engineers, tech leads, and business stakeholders

System design and architecture

• Ability to design and guide Kotlin adoption strategies for backend applications
• Experience designing backend systems using common architectural patterns (e.g., monolith, modulith, microservices)
