Senior Scala Engineer

Technologies we use

About the project

Your responsibilities

Our requirements

• Strong Scala skills, with production experience using an effect system (Cats Effect, ZIO, or Akka/Pekko) — we care more about depth of understanding than years on your CV.
• Experience designing or significantly contributing to event-driven systems in production — comfortable reasoning about ordering guarantees, idempotency, replay, and failure modes.
• Strong working knowledge of Apache Kafka — not just as a consumer API, but understanding partitioning, delivery guarantees, consumer groups, rebalance issues, and consumer lag.
• Hands-on Kubernetes skills sufficient to independently diagnose pod issues, resource limits, HPA behavior, and networking.
• Experience with both SQL and NoSQL databases, with a clear sense of when each is the right tool.
• Experience with microservices architecture, including awareness of common pitfalls (distributed transactions, eventual consistency, contract versioning).
• Ability to design for scale and growth — partitioning, sharding, tenant isolation, backpressure.
• Strong debugging and troubleshooting skills in distributed environments.

Optional

• Solid grasp of JVM internals — GC behavior, profiling, heap and thread dump analysis.
• Experience with observability: distributed tracing (OpenTelemetry, Jaeger), structured logging, metrics — for us this is core to daily work.
• Experience working in a cloud environment (Azure / GCP) — our stack runs primarily on AKS.

What we offer

• Work on a production-grade, large-scale system used by enterprise customers worldwide.
• Real technical challenges around performance, data volume, and distributed systems.
• Opportunities for continuous technical growth and deeper ownership over system design.
• Support from experienced engineers and a strong engineering culture.
• Influence on architectural and technical decisions within your team.
