OpenAISan Francisco, CALead ML engineering on OpenAI's Integrity team to build, deploy, and optimize LLMs and classifiers for content understanding, abuse prevention, and platform safety. Requires advanced degree, deep learning expertise, and LLM fine-tuning experience.
Build and operate an automated inference optimization platform spanning control planes, secure partner-side runners, compilers, and evaluation systems for new accelerator hardware. Requires 8+ years building large-scale distributed systems with strong performance and systems expertise.
As a Software Engineer, you will build and design the machine learning infrastructure for OpenAI's monetization and ads systems. This involves developing large-scale data pipelines, model training platforms, real-time inference systems, and experimentation frameworks to support high-throughput, low-latency advertising workloads.
Research Engineer/Scientist shaping personalities and behaviors of personalized AI models like ChatGPT using RL, reward modeling, synthetic data, and post-training methods. Requires strong ML engineering and research experience with large models.
Train frontier models to generate polished artifacts (docs, spreadsheets, slides) by owning post-training improvements across RL, data, evals, and alignment. Requires strong ML fundamentals and hands-on LLM/RL experience.
Train frontier models to operate computers, browsers, and desktops. Design experiments, build evals, own post-training pipelines (RL, data, graders), and ship improvements into OpenAI agents.
