As a Principal Engineer with Deep Engineer archetype in Kubernetes Platform, you will own technically complex, high-impact outcomes from problem definition through production. You will bring deep expertise in agent infrastructure and distributed systems to shape the platform's architecture and technical direction. You'll make sound trade-offs across security, isolation, performance, scalability, portability, cost, and developer experience, while remaining close to the code and operational reality.

• Define and deliver the technical strategy for secure, low-latency compute infrastructure for AI agents and untrusted workloads.
• Lead architecture and implementation of isolation, scheduling, lifecycle management, networking, policy enforcement, observability, and control-plane capabilities.
• Own end-to-end outcomes for ambiguous, cross-team initiatives, from design and prioritisation to launch, adoption, and measurable operational results.
• Advance portable, cloud-native execution across GCP and AWS while balancing platform consistency with regional and workload needs.
• Champion operational excellence for a tier-0 platform: reliability, security, privacy, incident learning, performance, and cost efficiency.
• Improve the developer experience through self-service APIs, automation, paved paths, and clear platform contracts.
• Set direction through written proposals and thoughtful technical decisions; mentor engineers and help grow an inclusive, high-performing team.
