About the role

Senior-level systems generalist role focused on building an automated inference optimization platform and control planes for multi-hour to multi-day campaigns, integrating hardware, compilers, runtimes, and secure partner workflows across OpenAI and external environments.

Responsibilities

  • Design, build, and operate durable APIs and control-plane services for multi-hour or multi-day optimization campaigns, including scheduling, retries, budgets, checkpoints, artifact lineage, and observability.
  • Build secure partner-side runner and grader software that can compile, execute, verify, and benchmark candidate artifacts on third-party accelerator hardware.
  • Integrate hardware profiles, ISA and toolchain context, compilers, runtimes, and inference-serving engines into a repeatable optimization workflow.
  • Turn research prototypes into reliable product surfaces with clear contracts, debuggable failure modes, reproducible outputs, and excellent developer ergonomics.
  • Develop correctness and performance evaluation systems spanning latency, throughput, memory use, utilization, and cost efficiency.
  • Build artifact, provenance, and qualification workflows that make optimized kernels, binaries, configurations, and reports safe to review and deploy.
  • Collaborate with Research, Inference Engineering, Infrastructure, Security, Product, and Strategic Partnerships to deliver production-ready solutions.
  • Drive technical architecture and execution across ambiguous, cross-functional initiatives that connect OpenAI systems with partner environments.

Qualifications

  • 8+ years of professional software engineering experience building large-scale distributed systems, infrastructure platforms, or cloud services, or equivalent depth of experience.
  • Strong programming skills in one or more of C++, Python, Go, or Rust.
  • Experience designing and operating highly available backend systems, APIs, job orchestration systems, or durable workflows for production workloads.
  • Strong understanding of distributed systems, Linux, networking, storage, containers, and modern cloud architectures.
  • Experience debugging complex systems and using measurement, profiling, and benchmarks to guide engineering decisions.
  • Proven ability to lead complex technical initiatives as a senior individual contributor and work effectively across organizational boundaries.
