About the Role

The Infrastructure team builds and operates the backbone of Physical Intelligence, supporting AI model training, large-scale simulation, and reliable deployment of intelligence across robot fleets. This role involves owning and scaling AI-native infrastructure, driving security and cost-awareness, hardening platform foundations, and improving developer experience.

Responsibilities

  • Own and scale AI-native infrastructure, including Kubernetes clusters and microservice platforms.
  • Operate and evolve Kubernetes clusters and service deployment patterns.
  • Build a scalable microservice platform for internal systems.
  • Support safe rollouts, upgrades, and rollback strategies.
  • Drive security, observability, and cost-aware infrastructure.
  • Build systems that surface reliability and performance issues early.
  • Improve cost visibility and enable cost-aware decision-making.
  • Harden platform foundations with multi-cloud considerations.
  • Design authentication/authorization flows, networking architecture, and quota/rate-limiting services.
  • Reduce infra churn by standardizing patterns, abstractions, and interfaces.
  • Improve developer experience by building clear, documented interfaces for platform infrastructure.
  • Support consistent local vs. remote development workflows.
  • Improve self-serve infrastructure usage.
  • Collaborate with researchers and engineers to understand requirements.
  • Translate fast-moving needs into reusable infrastructure.
  • Own systems end-to-end, from design through operation.

Requirements

  • Extremely strong first-principles thinking.
  • Familiarity with agent infrastructure, observability, security and sandboxing.
  • Deep experience with cloud platforms (GCP, AWS) and distributed systems.
  • Ability to reason about system bottlenecks, performance tuning, and cost optimizations.
  • Comfort with Kubernetes, cluster-level reliability, and service-oriented architectures.
  • Solid intuition around scalability, performance, and failure modes.
  • Experience with infrastructure-as-code (e.g. Terraform), containerization, and modern platform engineering practices.
  • Familiarity with logging, metrics, tracing, incident response, SLOs, and debugging complex distributed systems.
  • Strong cross-functional communication and ownership mindset.
  • Experience (4-6 years) working in fast-moving or early-stage environments with demonstrated growth trajectory.
  • Ability to spin up quickly on unfamiliar and ambiguous domains.
  • Strong sense of ownership.
  • Deep care about the company mission.
