Workload Porting & Performance Engineer | OpenAI
Careers
Workload Porting & Performance Engineer
Hardware - San Francisco and Seattle
OpenAI’s Infrastructure organization builds and evaluates the systems that power advanced AI workloads. We work closely with hardware, modeling, and architecture teams to ensure that new platforms deliver real-world performance aligned with workload needs.
Our team focuses on understanding workload behavior across evolving hardware platforms—bridging the gap between theoretical capability and observed system performance.
We are seeking a Workload Porting & Performance Engineer to evaluate new hardware platforms by porting benchmarks and real-world workloads, analyzing performance, and identifying system bottlenecks.
In this role, you will bring up workloads on new systems, characterize performance behavior, and adapt workloads to better utilize hardware capabilities. You will play a critical role in validating new platforms and ensuring that performance aligns with expectations across compute, memory, and networking subsystems.
This role requires strong hands‑on experience with performance analysis, workload optimization, and system‑level debugging across hardware and software boundaries.
This role is based in San Francisco, CA. We use a hybrid work model of 3 days in the office per week and offer relocation assistance.
Key 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
system and software engineers
Debug issues across the stack, including software, runtime, and hardware interactions.
Provide actionable insights to guide platform readiness and deployment decisions.
Qualifications
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.
Compensation
$342K – $555K
