Description
Lambda, The Superintelligence Cloud, is a leader in AI cloud infrastructure serving tens of thousands of customers. Our customers range from AI researchers to enterprises and hyperscalers. Lambda's mission is to make compute as ubiquitous as electricity and give everyone the power of superintelligence. One person, one GPU. If you'd like to build the world's best AI cloud, join us.
What You'll Do:
- Build and operate monitoring and alerting for cluster health , fabric, GPU, power/thermal, and job-level signals , to detect and respond to issues proactively
- Remotely deploy and configure large-scale HPC clusters for AI workloads using automation wherever possible
- Automate cluster lifecycle: operating systems, firmware, drivers, and networking, managed as code (Ansible, Terraform) rather than by hand
- Create runbooks and automated remediations for common cluster failure modes, designed so Support and HPC Support can run them safely
- Troubleshoot and resolve cluster issues across InfiniBand/RoCE, NCCL, GPU-direct, fabric, switching, and power , working closely with on-site deployment teams
- Participate in on-call rotations and lead incident response for cluster-level problems
- Contribute to and maintain Standard Operating Procedures, and feed clear requirements back to other engineering teams on simplification, stability, and operational efficiency
Requirements:
- 7+ years of experience in Site Reliability Engineering, HPC Engineering, DevOps, or a similar role
- Strong understanding of modern AI infrastructure, from GPU architectures to hardware performance optimization
- Strong understanding of Linux-based systems in a distributed environment
- Experienced configuring and troubleshooting InfiniBand (IB), RoCE, CLOS fabrics, 100GbE, Ethernet/switching, GPU-direct, and NCCL environments
- Solid understanding of Python and Go, with experience working with SWE teams to improve internal tooling
- Experience with monitoring and alerting tools (e.g., Prometheus, Grafana, Clickhouse)
- Proficiency in automation and configuration management tools (e.g., Ansible, Terraform)
- Excellent problem-solving and troubleshooting skills and an innate attention to detail
- Passion for continuous improvement and innovation
Nice to Have:
- Experience with machine learning / deep learning frameworks (PyTorch, TensorFlow) and benchmarking tools (DeepSpeed, MLPerf)
- Knowledge of containerization and orchestration technologies (e.g., Docker, Kubernetes)
- Experience building and/or operating HPC resources
- Depth in the NVIDIA hardware and firmware ecosystem
- Experience with data center power and thermal design
- Background in chaos engineering or similar reliability testing methodologies
- Understanding of compliance frameworks (SOC 2, ISO 27001, etc.)
Benefits:
- Generous cash & equity compensation
- Health, dental, and vision coverage for you and your dependents
- Wellness and commuter stipends for select roles
- 401k Plan with 2% company match (USA employees)
- Flexible paid time off plan
