Senior QA Engineer - Distributed Systems & Automation

We are seeking a Senior QA Engineer to help ensure the quality, reliability, scalability, and operational readiness of our automatic network operations platform. This role goes far beyond traditional functional testing. You will validate complex distributed systems, networking workflows, APIs, infrastructure automation, and large-scale deployment scenarios that power modern AI infrastructure environments.

This is a phenomenal opportunity to join a small, senior engineering team where you can directly influence product architecture and release confidence. You will collaborate closely with backend developers, infrastructure engineers, and network architects to build a world-class quality engineering practice focused on automation, observability, and robust testing frameworks. If you thrive on breaking complex backend environments and building continuous validation pipelines for high-performance scale, this is your next step.
