You will play a critical role in ensuring the quality, performance, and reliability of every release before it reaches our customers. Our 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. A meaningful part of this role is DevOps work, not just test authoring., * Design, build, and maintain integration, regression, and end-to-end tests for distributed systems running on Kubernetes, Slurm, and bare-metal GPU/CPU clusters * Extend our in-house end-to-end test automation framework and share ownership of the CI/CD testing infrastructure and pipeline * Build and run performance and scale benchmarks, and catch regressions before they ship * Automate cluster lifecycle and environment management across cloud and bare-metal environments * 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.) ## Related Videos - [Running Secure Life Science Research at Scale using Hybrid GPU HPC and Kubernetes 🧬](https://www.wearedevelopers.com/videos/100355-running-secure-life-science-research-at-scale-using-hybrid-gpu-hpc-and-kubernetes) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Continuous testing - run automated tests for every change!](https://www.wearedevelopers.com/videos/190-continuous-testing-run-automated-tests-for-every-change) - [Testing .NET applications a Tool box for every developer](https://www.wearedevelopers.com/videos/704-testing-net-applications-a-tool-box-for-every-developer) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) - [Discover the open source trio you didn’t expect: .NET and PostgreSQL on Linux](https://www.wearedevelopers.com/videos/2042-discover-the-open-source-trio-you-didn-t-expect-net-and-postgresql-on-linux) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 137 - AI'm not sure about this](https://www.wearedevelopers.com/magazine/485-dev-digest-137-ai-m-not-sure-about-this) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers)
