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.
