Feldera is looking for a Software Engineer: Reliability and Performance to ensure our platform runs flawlessly under real-world conditions. You will push our engine and control plane to its limits by designing automated tests, validating correctness under stress, and ensuring smooth upgrades and recovery.

What You'll Do

Design and run long-lived workloads that mimic production environments, including sustained load, skewed data distributions, and upgrade workflows.
Build metrics and dashboards to continuously measure throughput, latency, and resource efficiency to guide system improvements.
Run chaos and fault injection experiments involving node failures, crashes, network partitions, resource contention, and rolling upgrades.
Own and evolve CI/CD pipelines to make them faster, more reliable, and more reflective of production conditions.
Work closely with core systems engineers to pinpoint bottlenecks, identify regressions, and improve reliability mechanisms.

What We're Looking For

Strong background in systems engineering, performance testing, or site reliability engineering.
Fluency in Python and Linux fundamentals.
Experience with distributed systems and database concepts (consistency, fault tolerance, transactions).
Experience with CI/CD pipeline engineering (GitHub Actions, Docker, Kubernetes).
Hands-on experience running large-scale and long-running workloads, preferably in a cloud-native environment.
Curiosity, rigor, and the ability to design experiments that simulate messy real-world conditions.
