Clockwork.io – Software Driven Fabrics to increase GPU cluster utilization

Clockwork Systems was founded by Stanford researchers and veteran systems engineers who share a vision for redefining the foundations of distributed computing.

As AI workloads grow increasingly complex, traditional infrastructure struggles to meet the demands of performance, reliability, and precise coordination.

Clockwork is pioneering a software-driven approach to AI fabrics by delivering cross-stack observability to catch and quickly resolve problems, workload fault tolerance to keep jobs running through failures, and performance acceleration that dynamically routes and paces traffic to avoid congestion.

We are looking for a Software Development Engineer in Test who thrives in fast-paced startup environments and is excited to own our entire testing and CI/CD infrastructure.

You will play a critical role in ensuring the quality and reliability of every release before it reaches our customers.

This is a hands-on engineering role , not a manual QA position.

You’ll be deeply embedded in our engineering team, responsible for building robust automation, maintaining pipelines, and contributing directly to the product during quieter times.

• Design, build and maintain integration and regression tests for distributed systems
• Own and maintain the CI/CD testing infrastructure and pipeline
• Ensure all code releases meet high quality standards before shipping to customers
• Collaborate closely with engineers to identify gaps in test coverage and build tools or frameworks to fill them
• Investigate and diagnose build failures, flaky tests, and regressions.
• Contribute to engineering efforts beyond QA when appropriate (feature development, tooling, etc.)
