Customer Success Engineer

About the role

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 are looking for a Customer Success Engineer (CSE) to help engineering teams successfully adopt Kotlin Multiplatform (KMP) in real-world production environments. This role owns the end-to-end success of customers navigating their KMP adoption journey, ensuring they achieve tangible business and engineering outcomes through expert guidance. You will act as a trusted technical advisor, bridging deep Kotlin expertise with customer business goals to drive confidence and long-term platform adoption. You will translate complex technical concepts into actionable strategies that align with organizational maturity and product vision. Ultimately, you will enable teams to move from initial evaluation and experimentation to stable, scalable production usage of Kotlin Multiplatform.

Key facts

What you'll do

Investigate and clarify intricate customer use cases to frame feasible Kotlin Multiplatform adoption paths aligned with current architecture. Partner with stakeholders to evaluate technical constraints and co-define realistic adoption roadmaps that balance speed, quality, and risk. Diagnose migration and integration challenges within existing projects, guiding teams from fragmented prototypes toward consolidated shared codebases. Facilitate cross-functional workshops that align iOS, Android, and backend teams on common goals and interface contracts. Assess build performance and runtime behavior, then recommend targeted optimizations to resolve bottlenecks in KMP compilation and testing. Collaborate with product and engineering teams to channel customer feedback directly into the KMP tooling and runtime roadmap. Mentor technical leads on best practices for structuring multiplatform modules, dependency management, and API design. Track adoption metrics and success indicators, translating qualitative feedback into measurable insights for internal stakeholders. Act as the primary escalation partner for complex technical issues, coordinating with JetBrains specialists to unblock critical production scenarios. Represent JetBrains in customer forums and advisory sessions, shaping the narrative around Kotlin Multiplatform best practices.
