The role is accountable for the architecture, reliability, scalability, security and cost of every layer beneath the platform's applications, from the cloud, network and compute foundation to the serving, orchestration and streaming systems that workloads run on. This engineering leader partners closely with the AI Platform Software and Safety leads to own and develop the AI/ML platform. This role architects, builds and operates AI infrastructure as software, supporting large language models, predictive models, agentic systems and traditional software applications across the MLOps lifecycle. This is a hands-on engineering role that requires a technical leader to demonstrate ownership, accountability and leadership. This role is based in Madison, WI. Essential Duties Include, but are not limited to, the following: Design and own the platform's cloud and Kubernetes foundation, including account and network topology, VPC and subnet design, private connectivity, ingress and egress control, DNS and certificates, and the provisioning, upgrade, migration, multi-tenant isolation and security of production clusters. Lead the platform's expansion across clusters and regions, covering topology, identity federation, state and data placement, traffic management and failure domains, and evaluate multi-cloud where business need warrants it. Own infrastructure-as-code and GitOps for the platform, including module design, state management, environment promotion, drift control, and the testing and rollback of infrastructure changes; build and operate the CI/CD and deployment tooling that platform software releases run on in partnership with the AI Platform Software lead. Architect, build and operate production model serving and GPU infrastructure for large language and predictive models, including scheduling, multi-tenancy, autoscaling, low-latency serving, inference optimization (quantization, batching, graph compilation), and capacity planning and cost attribution for shared compute. Partner with the AI Platform Software and Safety leads on the model lifecycle by providing the infrastructure it runs on, including reproducible data, feature and training pipelines with dataset-to-model lineage, promotion environments, the traffic-shifting and rollback mechanisms behind canary, shadow and A/B rollout, and pipeline enforcement of the evaluation and promotion gates. Architect, build and operate workflow orchestration and event-streaming infrastructure, including workflow and state-machine design, event-driven triggers and scheduling, retries and idempotency, topic and partition design, schema management, delivery semantics and cross-region replication. Own the observability stack and service level objectives for infrastructure services, with proactive detection across the platform; lead disaster-recovery strategy as a business tradeoff between cost and recovery time and recovery point objectives; and serve as the escalation point for complex infrastructure incidents, leading the post-incident analysis that drives systemic reliability improvements.
