đź“‹ Description
- • As a Software Engineer on the Workload Enablement team within OpenAI’s Scaling organization, you will play a critical role in ensuring that cutting-edge AI workloads run reliably and efficiently on emerging hardware platforms, directly enabling the deployment of next-generation models.
- • You will be responsible for porting, validating, and optimizing key inference and training workloads on new and early-access systems, building comprehensive test harnesses and stress benchmarks that reflect real-world end-to-end behavior, and diagnosing performance bottlenecks across compute, memory, networking, and storage subsystems.
- • The Scaling team designs and delivers the architectural and engineering foundation for OpenAI’s AI infrastructure, spanning system software, high-speed networking, platform architecture, fleet monitoring, and performance optimization to support the training and deployment of frontier models.
- • You will collaborate closely with systems bring-up engineers, vendor partners, and internal ML teams to ensure platforms are not only performant but also operationally robust, scalable, and observable—integrating with Kubernetes, telemetry systems, and failure triage workflows.
- • In this role, you will deepen your expertise in high-performance computing, distributed systems, and AI infrastructure, gaining hands-on experience with the latest accelerators, interconnect technologies (like NVLink and RDMA), and software stacks while contributing to the reliability and scalability of OpenAI’s AI platform.
🎯 Requirements
- • BS in Computer Science, Electrical Engineering, or equivalent practical experience
- • 5+ years of experience in ML systems, performance engineering, distributed systems, or HPC
- • Strong hands-on experience with PyTorch and modern LLM training/inference stacks, large-scale distributed training concepts (data/model/pipeline parallelism), and RDMA-based communication libraries (NCCL or RCCL)
🏖️ Benefits
- • Opportunity to work on cutting-edge AI infrastructure at the forefront of technological innovation
- • Collaborative, mission-driven culture focused on safe and beneficial AI development
- • Access to advanced hardware and software tools for performance analysis and system optimization
