Staff Software Engineer

Strong expertise with Java/JVM, building scalable, high-performance backend systems; open to leveraging other languages when appropriate.

Solid understanding of distributed systems concepts, including high availability, CAP theorem, and fault tolerance.

Deep experience with relational databases (PostgreSQL) and key–value / non-relational storages (Redis).

Practical experience with containerization and cloud-native environments, including Docker and Kubernetes.

Hands-on experience with message brokers such as RabbitMQ or Kafka.

Wrike’s Backend Reliability (BRE) team is the backbone of our backend infrastructure and the guardian of our uptime.

Our mission is to achieve and sustain 99.99% availability while building the tools, components, and safety nets that the entire engineering organization relies on.

As a Senior / Staff Backend Engineer on this team, you won’t just close tickets - you’ll architect core reliability solutions that shape how Wrike scales, performs, and recovers from failure.

Design, build, and maintain critical reliability components such as HTTP rate limiters, internal DB schema migration tools, circuit breakers, and distributed Redis-based caching.

Troubleshoot complex production issues, optimize PostgreSQL usage, and ensure our distributed systems remain performant and stable under high load.

Lead preliminary investigations during severe production incidents: identify likely root causes, assess impact, and propose mitigation options.
