Software Engineer - Compute

In 2012, Lambda started with a crew of AI engineers publishing research at top machine-learning conferences. We began as an AI company built by AI engineers. That hasn't changed. Today, we're on a mission to be the world's top AI computing platform. We equip engineers with the tools to deploy AI that is fast, secure, affordable, and built to scale. Whether they need powerhouse GPU hardware on-site or the flexibility of cloud-based solutions, we've got the horsepower to make it happen. Lambda’s AI Cloud has been adopted by the world’s leading companies and research institutions including Anyscale, Rakuten, The AI Institute, and multiple enterprises with over a trillion dollars of market capitalization. Our goal is to make computation as effortless and ubiquitous as electricity.

If you'd like to build the world's best deep learning cloud, join us.

• Note : This position requires presence in our San Francisco office location 4 days per week; Lambda’s designated work from home day is currently Tuesday.

What You’ll Do

Join a functional sub-team of Compute at Lambda which is responsible for the development of a critical internal testing system that manages AI testloads across large GPU compute clusters.

Improve code quality, internal validation, and support for new topologies in the testing system.

Work on scalability challenges, enabling the testing system to support very large-scale clusters.

Transition communication mechanisms from SSH to node agents, exploring ZeroMQ or Redis streams.

Fix bugs and operational blockers to enable smoother handoff to non-engineering teams.

Contribute to the implementation efforts, and collaborate with the team  on high-level architecture or strategic direction.

Work closely with the HPC-Ops and other internal consumers of the testing system.

You

Have strong proficiency in Python, backed by 3-5 years of professional software development experience, ideally leaning towards 5 years.

Solid understanding of Go, with the capability to develop efficient and maintainable code.

Have hands-on experience with containers (Docker preferred).

Have familiarity with Kubernetes (K8s is a plus but not required).

Are comfortable working with Linux-based systems in a distributed environment.

Have experience working with large, complex codebases and improving their maintainability.

Have learned from past large-scale technical mistakes and grown from them.

Can take ownership of an internal tool and drive it forward.

Are eager to learn on the job, especially regarding the testing system’s architecture.

Are adaptable and enjoy working in fast-moving, high-impact environments.

Communicate well with cross-functional teams and collaborate effectively on large-scale engineering efforts.

Nice to Have

Experience with Slurm or Kubernetes-based cluster management.

Familiarity with high-performance computing (HPC).

Understanding of GPU compute environments (CUDA knowledge is not required).

Interest in validating AI workloads in customer environments for debugging or preventative maintenance.

Salary Range Information

Based on market data and other factors, the annual salary range for this position is $170,000-$230,000. 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.
