About the role

Responsibilities

  • Push massive compute clusters to their limits as a core contributor to a novel in-house container orchestration platform that scales beyond Kubernetes.
  • Develop and maintain FastAPI and gRPC APIs serving as the interface for agentic infrastructure in training and production.
  • Use Terraform to stand up and evolve complex infrastructure for research and production.
  • Collaborate with research teams to stand up and optimize systems for novel AI training runs and experimental applications.

Requirements

  • Deep experience working on large-scale machine learning infrastructure, reasoning about training at scale, identifying bottlenecks, and engineering optimization solutions.
  • Ability to build new things from 0-1 quickly and scale them 1,000,000x.
  • Keen eye for performance and optimization in complex, globally-distributed systems.
  • Experience with cloud platforms and infrastructure-as-code like Terraform.
  • Driven by solving complex, ambiguous problems at the intersection of infrastructure scalability, virtualization efficiency, and agentic capabilities.
  • Deep technical expertise in virtualization and containerization technologies (e.g. Kata, Firecracker, gVisor, Sysbox) and passion for optimizing runtime performance.
