Details
OpenAI’s Infrastructure organization builds and evaluates the systems that power advanced AI workloads. This team focuses on understanding workload behavior across evolving hardware platforms and bridging the gap between theoretical capability and observed system performance.
This role is based in San Francisco, CA and uses a hybrid work model (3 days in the office per week). The company offers relocation assistance for eligible employees.
Responsibilities
- Port and enable benchmarks and real-world workloads on new hardware platforms.
- Evaluate system performance across compute, memory, storage, and networking subsystems.
- Identify and analyze performance bottlenecks and inefficiencies.
- Adapt and optimize workloads to better utilize hardware capabilities.
- Develop and run performance experiments and profiling workflows.
- Compare expected vs. observed performance and provide feedback to hardware architecture teams, performance modeling teams, and system/software engineers.
- Debug issues across the stack, including software, runtime, and hardware interactions.
- Provide actionable insights to guide platform readiness and deployment decisions.
Requirements
- Experience with performance analysis, benchmarking, or workload optimization.
- Strong understanding of system architecture, including CPU/GPU, memory, and I/O subsystems.
- Experience porting or adapting workloads across different hardware platforms.
- Familiarity with profiling tools and performance debugging techniques.
- Ability to identify root causes of performance issues across hardware/software boundaries.
- Experience working in large-scale or distributed system environments.
Preferred Skills
- Experience with AI/ML workloads, including training or inference systems.
- Familiarity with GPU or accelerator-based systems.
- Experience working with low-level performance tools (profilers, tracing, microbenchmarks).
- Background in systems software, compilers, or runtime optimization.
- Experience collaborating with hardware and architecture teams on performance validation.
Benefits
- Medical, dental, and vision insurance with employer contributions to Health Savings Accounts.
- Pre-tax accounts for Health FSA, Dependent Care FSA, and commuter expenses.
- 401(k) retirement plan with employer match.
- Paid parental leave and paid medical/caregiver leave.
- Paid time off (flexible PTO for exempt employees; specified days for non-exempt employees) and 13+ paid company holidays.
- Mental health and wellness support, employer-paid basic life and disability coverage.
- Annual learning and development stipend.
- Daily meals in offices and meal delivery credits as eligible.
- Relocation support for eligible employees and additional taxable fringe benefits.
