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.\nTo learn more, visit www.clockwork.io.\nSummary\nWe are looking for a Software Development Engineer in Test who thrives in fast-paced startup environments and is excited to be a co-owner and major contributor to our testing and CI/CD infrastructure. You will play a critical role in ensuring the quality, performance, and reliability of every release before it reaches our customers.\nOur software runs on production GPU and CPU clusters across Ethernet, RDMA/RoCE, and InfiniBand networks. Testing here means standing up real multi-node clusters, running real workloads against them, and measuring what happens. This is a hands-on engineering role, not a manual QA position. You will be deeply embedded in our engineering team, responsible for building robust automation, maintaining pipelines, and contributing directly to the product during quieter times.
