Software Engineer, Frontier Systems

New Today

About the Team The Frontier Systems team at OpenAI builds, launches, and supports the largest supercomputers in the world that OpenAI uses for its most cutting edge model training. We take data center designs, turn them into real, working systems and build any software needed for running large-scale frontier model trainings. Our mission is to bring up, stabilize and keep these hyperscale supercomputers reliable and efficient during the training of the frontier models. About the Role On the Frontier Systems team, you’ll build critical infrastructure that keeps our supercomputers running reliably for cutting-edge AI research. Even a single hardware failure can derail a large-scale training run, so minimizing disruptions is core to the mission. Engineers here own their work end-to-end and are trusted to make a real impact. This role is for someone who goes deep - who thrives on root-causing system-level issues and building automation to catch and fix problems at scale. In this role, you will: Own and improve the system health checks that keep our hyperscale supercomputers stable during model training.
Lead deep dives into hardware failures and system-level bugs to understand how things break at scale.
Build automation that monitors and fixes issues across thousands of machines - so researchers can keep moving without interruption.
You might thrive in this role if you have: 7+ years of industry experience in software engineering
Proficiency with Python and shell scripting
A high degree of comfort digging into noisy data with SQL, PromQL, and Pandas or any other tool necessary
Experience developing reproducible analyses
A balance of strengths in building and operationalizing
Prior hardware expertise is not required for this role. Bonus if you have: Experience with low level details of hardware components, protocols, and associated Linux tooling (e.g., PCIe, Infiniband, networking, power management, kernel perf tuning)
Experience with visualization of large data centers and networks.
Expertise with network operations and tooling
Expertise with power management and stabilization
