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

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

Engineering at Lambda is responsible for building and scaling our cloud offering. Our scope includes the Lambda website, cloud APIs and systems as well as internal tooling for system deployment, management and maintenance.

About the Role

We are seeking a Senior Software Engineer to join our Managed Kubernetes (Mk8s) team. You will play a crucial role in shaping the architecture, reliability, and automation of our Kubernetes-based infrastructure, which powers mission-critical workloads across our global platform.

What You’ll Do

- Design, build, and maintain scalable control plane services, operators, and custom Kubernetes controllers, while developing automation in Python/Go for end-to-end cluster lifecycle management — including provisioning, upgrades, patching, and deletion.

- Identify gaps and develop internal tools, APIs, and command-line interfaces (CLIs) that enable customers and ML/AI teams to deploy and effectively monitor inference services.

- Write resilient systems that gracefully handle failure across large-scale distributed environments.

- Develop automated tests to ensure quality and stability, and validate the clusters to identify and address hardware issues before delivery.

- Support and debug production issues through on-call rotation.

You

- Have 6+ years of experience in software engineering, 3+ years leading large-scale complex projects, or tech lead.

- At least two years of experience working on orchestration and deployment systems

- Experience using Kubernetes and third-party operators (CRDs, CSI, CNI, etc.).

- Strong programming skills in Go and Python; ability to collaborate effectively on shared codebases

- Take pride in owning and delivering core components of products and platforms.

- Experience with infrastructure-as-code tools (e.g. Terraform, Pulumi).

- Solid knowledge of Linux systems, networking, containers, and cloud infrastructure.

Nice to Have

- Deep Kubernetes and Linux expertise

- Experience operating the control plane and low-level pieces of large-scale Kubernetes clusters

- Experience with user-level restrictions and hardening (e.g. AppArmor)

- Experience with HPC clusters, environments & tooling

- Experience with machine learning/AI frameworks

- Expertise with hybrid or multi-cloud Kubernetes environments.

- Familiarity with GPU, Infiniband, or high-performance computing on K8s.

- Past contributions to CNCF projects or Kubernetes SIGs a plus.

If you don’t meet all of these requirements but believe you may be a good fit, please still apply and provide a cover letter that helps us understand your experience and readiness for this role.
