Stream Processing Engineer (Apache Flink Internals) at BairesDev
We are seeking a Stream Processing Engineer with experience in Apache Flink internals to work on the engine itself, not jobs that run on top of it. The work covers Flink runtime, scheduler, state backend, checkpointing infrastructure, and SQL/Table API at petabyte scale. The technology stack centers on the open source Apache Flink project and the wider streaming ecosystem (Kafka, Iceberg, Hadoop), with ample scope for upstream contribution.
We're looking for engineers who have worked on engine-level code in Flink or comparable distributed streaming systems and are comfortable with stateful processing, event-time semantics, and fault-tolerant execution.
What You'll Do
Contribute production-grade code to the Apache Flink project.
Debug and optimize Flink internals — runtime, scheduler, state backend, checkpointing, backpressure — at petabyte scale.
Improve performance and scalability of stateful stream processing in production environments.
Profile and tune JVM behavior (GC, memory layout, concurrency) at the engine level.
Collaborate with cross-functional engineering teams and open source committers on integrations and ecosystem work.
Mentor senior engineers and raise the engineering bar through code reviews and design critiques.
What We Are Looking For
6+ years of experience in software development.
Strong Java skills.
Experience with dist
