Senior Software Engineer, AI Infrastructure

About this role

Mirantis is building a new enterprise AI infrastructure product that lets organizations run and govern large language models on their own Kubernetes clusters. You will join a small senior team early, with broad ownership of the model-serving layer and its path to production. What you'll do Design and build LLM serving infrastructure on Kubernetes: deployment, GPU scheduling, scaling, and model lifecycle management. Package the platform for enterprise environments: Helm-based installs, upgrades, and restricted/offline networks.

Integrate the serving layer with the platform's API gateway, identity, and metering services. Build the observability for operating GPU inference in production (serving metrics, GPU telemetry). Contribute across a multi-service codebase and help set engineering direction through design docs and reviews. What we're looking for: 5+ years of software engineering experience in infrastructure, platform, or distributed systems.

Deep hands-on Kubernetes experience: building and operating production workloads and Helm charts, not just consuming managed clusters. Experience with GPU workloads or LLM inference, or strong adjacent systems experience and a track record of learning fast. Strong Go programming skills; solid CI/CD and infrastructure-as-code skills. Fluency with AI-assisted development tools (Claude Code, OpenAI Codex) as part of your daily engineering workflow.

Comfortable with high autonomy on a small, remote-first, written-culture team. Nice to have: Inference performance work (quantization, batching, caching) or distributed serving frameworks. Enterprise deployment experience: air-gapped installs, SSO/OIDC, supply-chain security. UI development experience (e.g. React/TypeScript), useful as the product's management surfaces grow. Open-source contributions in the Kubernetes or ML-infrastructure ecosystems What does Mirantis offer you?
