Responsibilities

• At 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…
• The 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…
• Day to day, you will
• Design, build, and operate backend services that decide what a customer is entitled to and what their usage costs.
• Own flows end to end, from ingesting licensing and purchase data from upstream systems to enforcing quotas and recording consumption.
• Evolve our domain model to handle new commercial structures, combining seat-based plans and usage-based models.
• Design integrations with external systems, ensuring correctness through idempotency, ordering, reconciliation, and eventual consistency.
• Plan and execute live data migrations using feature flags, dual writes, backfills, and verification at every stage.
• Build observability into our systems by defining invariants, metrics, and alerts to catch silent divergence before customers do.
• Design internal APIs with explicit focus on versioning, backward compatibility, and developer experience for other JetBrains teams.
