Simulation Applications Engineer

About this role

OpenAI is seeking a Simulation Applications Engineer to build production-grade pipelines that automate robotics model training, evaluation, and hardware validation. You'll own CI/CD systems, orchestration infrastructure, and metrics tooling that enable large-scale simulation runs and seamless hardware-in-the-loop integration.

What you'll do

• Build and maintain CI/CD pipelines and presubmit checks for simulation code, environments, and tasks
• Implement end-to-end automation for model evaluation in simulation (SIL) and hardware-in-the-loop (HIL) runs with metric computation and reporting
• Design APIs and connectors for research and training systems to schedule, seed, and batch simulations
• Build scheduling and orchestration infrastructure to run tens of thousands of concurrent rollouts with GPU optimization
• Create metrics, dashboards, and presubmit tests to detect simulation health regressions and measure fidelity
• Implement artifact versioning, environment immutability, experiment provenance, and resource quota management

What they're looking for

• CI/CD pipelines and infrastructure at scale
• Distributed compute and cloud GPU workload orchestration
• Hardware-in-the-loop (HIL) and software-in-the-loop (SIL) systems
• Python, C++, or Rust
• Container orchestration (Kubernetes) and distributed task queues
• System observability, metrics, and alerting
• API design and developer ergonomics
• Reinforcement learning tooling or large-scale data pipelines (bonus)
