Job 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.

This position is expected to participate in an on‑call rotation.

What You’ll Do

• Serve as a senior technical escalation point, troubleshooting the hardest infrastructure and platform issues down to the hardware, driver, or kernel level when needed

• Quickly and accurately distinguish between hardware failures, driver issues, kernel‑level problems, and customer workload misconfiguration, so issues get resolved correctly the first time

• Proactively identify process, tooling, and documentation gaps, and go fix them, not just wait for them to be assigned

• Use AI tools effectively to build scripts, automations, or small internal tools that close real operational gaps (no professional development background required)

• Perform root‑cause analysis across distributed systems, clusters, and GPU infrastructure

• Craft clear documentation of solutions and contribute to evolving support procedures

• Collaborate closely with engineering teams to turn recurring customer pain points into permanent fixes

• Take escalations from peers while training and mentoring them in the process

• Participate in a rotating on‑call schedule, owning major incidents and major customer issues

• Be ready to roll up your sleeves and pitch in wherever needed, especially during fast, high‑volume deployments

You

• 3+ years of hands‑on HPC experience in an administration, support, or engineering role.

• Very strong understanding and experience supporting Linux in a system administration role.

• Proven experience in HPC environments, showcasing your expertise in Linux cluster administration, with strong preference for Kubernetes and/or Slurm for cluster orchestration.

• Strong coding ability and CI/CD experience, with a track record of using AI‑assisted tools to move fast.

• Proficiency with monitoring/logging tools (Prometheus, Grafana, Datadog).

• Strong skills in log analysis, debugging kernel‑level issues, and performance profiling.

• Experience with CUDA, NCCL, NVLink, GPUDirect RDMA.

• Experience with high throughput networking technologies(IB/RoCE).

• Knowledge of distributed AI/ML or HPC workloads.

• Knowledge of TCP/IP, VPN, and firewalls in cloud environments.

• Ability to work independently and mentor junior support engineers.

Nice to Have

• Experience with virtualization and container (Docker, Kubernetes) technologies.

• Experience with neoclouds/GPU cloud providers.

• Flexible availability for potential shifts outside of normal working hours/weekends.

• Experience with high performance storage systems.

• Familiarity with infrastructure‑as‑code tools (Terraform, Ansible, etc.)

• Experience with Nvidia GPUs and Infiniband.

Salary Range Information

This is a salaried exempt role. The annual salary range for this position has been set based on market data and other factors. However, a salary higher or lower than this range may be appropriate for a candidate whose qualifications differ meaningfully from those listed in the job description.
