Senior Software Engineer, AI Infrastructure

Company Description Mirantis, an IREN company, is the Kubernetes-native AI infrastructure company, enabling organizations to build and operate scalable, secure, and sovereign infrastructure for modern AI, machine learning, and data-intensive applications. By combining open source innovation with deep expertise in Kubernetes orchestration, Mirantis empowers platform engineering teams to deliver composable, production-ready developer platforms across any environment—on-premises, in the cloud, at the edge, or in sovereign data centers. As enterprises navigate the growing complexity of AI-driven workloads, Mirantis delivers the automation, GPU orchestration, and policy-driven control needed to manage infrastructure with confidence and agility. Committed to open standards and freedom from lock-in, Mirantis ensures that customers retain full control of their infrastructure strategy. https://www.mirantis.com/ Job Description 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 producti on. 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. Qualifications 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. Additional Information What does Mirantis offer you? - Work with an established Silicon Valley leader in the cloud infrastructure industry; - Work with exceptionally passionate, talented and engaging colleagues, helping Fortune 500 and Global 2000 customers implement next-generation cloud technologies; - Be a part of cutting-edge, open-source innovation; - Thrive in the high-energy environment of a young company where openness, collaboration, risk-taking, and continuous growth are valued; - Professional development and training; - Attend conferences and working groups; - Company outings, happy hours, hackathons, and tech talks; - Receive a competitive compensation package with a strong benefits plan.
