You will focus on designing backend services, keeping complex commercial flows correct, and tackling hard distributed systems challenges on the critical path of every paid request.\nAbout JetBrains\nWe create intelligent software development tools for developers and teams. More than 15 million users, over 300,000 companies, and 88 of the Fortune Global Top 100 rely on our products to solve real, complex problems. Our mission is simple: make development teams more productive and AI adoptable at scale.\nWhat you’ll do\nAt JetBrains, the Cloud Platform department builds the underlying infrastructure that powers authentication, paid capabilities, usage metering, and accounting. Within this department, the Licensing & Billing team sits right at the center of our commercial model, turning what a customer buys into what they are actually allowed to use, and accounting for that consumption accurately enough to bill on.\nThe complexity of our entitlement, quota, and metering systems continues to grow. In this role, you will own the correctness and evolution of these backend services, take full ownership of end-to-end data flows, tackle distributed consistency across unreliable upstream systems, and ensure revenue-affecting data migrations happen cleanly without taking services offline.\nDay to day, you will:\nDesign, build, and operate backend services that decide what a customer is entitled to and what their usage costs.\nOwn flows end to end, from ingesting licensing and purchase data from upstream systems to enforcing quotas and recording consumption.\nEvolve our domain model to handle new commercial structures, combining seat-based plans and usage-based models.\nDesign integrations with external systems, ensuring correctness through idempotency, ordering, reconciliation, and eventual consistency.\nPlan and execute live data migrations using feature flags, dual writes, backfills, and verification at every stage.\nBuild observability into our systems by defining invariants, metrics, and alerts to catch silent divergence before customers do.\nDesign internal APIs with explicit focus on versioning, backward compatibility, and developer experience for other JetBrains teams.\nImprove system performance and reliability under continuous production load while decommissioning legacy subsystems.\nWrite integration tests against real dependencies and maintain reliable test infrastructure.\nInvestigate production incidents, find root causes, and follow through on lasting fixes.\nWhat you’ll bring\nAn engineer’s dedication to accuracy, especially in domains where system errors have direct financial impact.\nPragmatic judgment when designing distributed systems where correctness under unreliable delivery is the main constraint.\nA habit of trusting metrics, traces, and logs to understand production behavior rather than relying on assumptions.\nComfort navigating and simplifying large existing codebases containing legacy decisions.\nClear, direct communication skills to agree on API contracts across teams with different priorities.\nA focus on testing as an essential design tool rather than an afterthought.\nWhat you’ll need\nA proven track record of building and operating backend services on the JVM platform using Kotlin or Java.\nA solid working knowledge of relational databases, including transactions, isolation levels, locking, indexing, and live schema migrations (PostgreSQL preferred).\nA deep understanding of distributed systems patterns, such as idempotency, retry strategies, eventual consistency, and data reconciliation.\nPractical experience making live data migrations or system changes without downtime using feature flags and staged rollouts.\nExperience designing versioned, backward-compatible APIs for other engineering teams.\nHands-on experience with event-driven architectures and message brokers like Kafka.\nThe ability to diagnose, debug, and resolve production incidents in complex environments.\nProficiency in both written and spoken English.\nWhat success looks like\nSuccess in this role means building a bulletproof entitlement and metering foundation that product teams can trust without hesitation. You will have successfully migrated live commercial systems to support new billing models without downtime or data divergence. Silent errors will be caught automatically by system invariants before affecting users, and internal teams will integrate seamlessly with your clean, versioned APIs.\n\nWhy join JetBrains? \nStrong base salary.
