OpenAI의 Foundations 팀에서 대규모 AI 모델을 위한 고성능 추론 시스템을 설계하고 구축할 리드급 엔지니어를 찾습니다. GPU 성능 엔지니어링 및 분산 시스템에 대한 깊은 이해가 필수적이며, 연구 아이디어를 실제 시스템 제약 조건 내에서 구현하는 역할을 수행합니다. 모델 아키텍처와 최적화의 교차점에서 연구를 가속화하는 핵심적인 시스템을 개발하게 됩니다.
The Foundations team focuses on how model behavior changes as we scale models, data, and compute. The team studies the interactions between model architecture, optimization, and training data, and uses those insights to guide how new models are designed and trained.
In this role, you will build the systems that enable advanced AI models to run efficiently at scale. You will operate at the intersection of model research and systems engineering, translating new architectural ideas into high-performance inference systems that surface real tradeoffs in performance, memory, and scalability.
Your work will directly influence how models are designed, evaluated, and iterated on across the research organization. By developing and evolving high-performance inference infrastructure, you will enable researchers to explore new ideas with a clear understanding of their computational and systems implications.
This is not a product-serving role. Instead, it is a research-enabling systems role focused on performance, correctness, and realism - ensuring that AI research is grounded in what can actually scale.
Design and build high-performance inference runtimes for large-scale AI models, with a focus on efficiency, reliability, and scalability.
Own and optimize core execution paths, including model execution, memory management, batching, and scheduling.
Develop and improve distributed inference across multiple GPUs, including parallelism strategies, communication patterns, and runtime coordination.
Implement and optimize inference-critical operators and kernels informed by real-world workloads.
Partner closely with research teams to ensure new model architectures are supported accurately and efficiently in inference systems.
Diagnose and resolve performance bottlenecks through profiling, benchmarking, and low-level debugging.
Contribute to observability, correctness, and reliability of large-scale AI systems.
Have experience building production inference systems, not just training or running models.
Are comfortable with GPU-centric performance engineering, including memory behavior and latency/throughput tradeoffs.
Have worked on multi-GPU or distributed systems involving batching, scheduling, or runtime coordination.
Can reason end-to-end about inference pipelines, from request handling through execution and output streaming.
Are able to understand research ideas and implement them within real system and performance constraints.
Enjoy solving hard, ambiguous systems problems that only emerge at scale.
Prefer hands-on technical ownership and execution over abstract design work.
