Join us and help build the platform engineers turn to to ship AI products. THE ROLE As Senior Manager of Cloud Platform and Site Reliability, you will lead and grow the org responsible for the infrastructure that powers Baseten's machine learning platform. This is a manager-of-managers role: you will lead team leads across our Cloud Platform and Site Reliability Engineering functions, setting the technical direction, defining reliability standards, and building the organizational muscle to scale our infrastructure alongside the product. You will own the end-to-end health of our cloud infrastructure and SRE practice — from coaching your leads through complex incident response and enterprise customer escalations, to shaping the multi-year roadmap for multi-cloud capacity, GPU inference infrastructure, and observability platforms. You operate at the intersection of people, strategy, and systems: you know how to build and develop strong teams, hold a high bar for engineering excellence, and make principled tradeoffs between long-term investment and short-term operational demands. This role requires someone who can zoom out to set org-level direction while remaining technically credible enough to engage meaningfully in architectural decisions across Kubernetes, multi-cloud infrastructure, and reliability engineering. RESPONSIBILITIES - Lead, grow, and develop team leads across the Cloud Platform and Site Reliability Engineering orgs, building a culture of ownership, technical excellence, and continuous improvement. - Set the technical direction and roadmap for infrastructure, reliability, and platform engineering at the org level — balancing near-term operational needs with long-term strategic investments. - Own the reliability posture of the platform end-to-end, establishing and enforcing org-wide standards for SLOs/SLIs, incident response, observability-as-code, runbooks, and post-incident reviews. - Drive cross-functional collaboration with product, engineering, and customer-facing teams to ensure infrastructure capabilities and reliability investments align with product goals and enterprise customer requirements. - Oversee incident management and escalation processes for high-severity production issues, ensuring clear communication, rapid resolution, and systemic follow-through. - Translate recurring operational pain points and customer feedback into roadmap priorities, product improvements, and runbook enhancements across both teams. - Ensure best practices for CI/CD, infrastructure-as-code, GitOps, Kubernetes, and cloud resource management are consistently adopted and maintained across the org. - Partner with forward-deployed and customer success teams to support enterprise accounts with strict SLAs and complex infrastructure requirements. - Navigate ambiguity and make sound architectural and organizational tradeoffs, avoiding unnecessary complexity while enabling your teams to move fast. - Demonstrate accountability, pride of ownership, and high standards — and expect the same from your leads and their teams. REQUIREMENTS - Bachelor's, Master's, or Ph.D. degree in Computer Science, Engineering, Mathematics, or a related field. - Proven experience managing managers and leading multiple high-performing infrastructure, platform, or SRE teams in a fast-paced, high-growth environment. - Deep technical expertise in Kubernetes (multi-cloud across EKS, GKE, or similar), cloud infra
