Software Engineer in Systems

Openai
San Francisco, CA

About the Team

The Platform Systems team operates at the intersection of cutting-edge AI and distributed systems. We do the engineering and research required to train our flagship models on our largest custom built supercomputers.

We build our own model training software, and focus on the lower layers of the stack including collective communication, scheduling, compute efficiency, parallelism strategies, fault tolerance, and observability.

The models we train are key ingredients to the AI research progress at OpenAI and the field as a whole, and we continually incorporate learnings from our entire research org into our training platform.

About the Role

As a software engineer in systems, you will design and build distributed systems used to train our next generation models.

San Francisco preferred. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees.

In this role, you will:

  • Build systems to distribute work across massive GPU clusters efficiently.

  • Design and implement methods to make our training stack more efficient & scale up to our next generation super computers.

  • Design and implement methods to robustly train models in the presence of hardware failures.

  • Build tooling to help us better understand problems in our largest training jobs.

You might thrive in this role if you:

  • Love getting into low level details about performance.

  • Are passionate about building stable and highly efficient distributed systems.

  • Have a background in high performance computing and/or low level systems.
