The opportunity
The Platform Systems team at OpenAI operates at the intersection of cutting-edge AI and large-scale distributed systems. We build the engineering and research infrastructure required to train OpenAI’s flagship models on some of the world’s largest, custom-built supercomputers.
What you'll do
Design and build distributed failure detection, tracing, and profiling: systems for large-scale AI training jobs
Develop tooling to identify slow, faulty, or misbehaving nodes and provide: actionable visibility into system behavior
Improve observability, reliability, and performance across OpenAI’s training platform
Debug and resolve issues in complex, high-throughput distributed systems
Collaborate with systems, infrastructure, and research teams to evolve platform capabilities
Extend and adapt failure detection systems or tracing systems to support new training paradigms and workloads
What they're looking for
- Care deeply about performance, stability, and observability in distributed systems
- Enjoy finding and fixing issues in large-scale systems and automating operational workflows
- Have experience writing low-level software where system details matter
- Understand hardware, operating systems, networking, concurrency, and distributed systems
