About the job
We’re looking for software engineers to join the Human Data team and build the platforms, prototypes, tools, and infrastructure that power how our AI models are trained, aligned, and evaluated. You’ll partner with researchers and cross-functional teams to bring alignment ideas to life, influence future model training, and shape how models interact with the real world.
Responsibilities
Build and maintain robust full-stack systems for feedback collection, data labeling, and evaluation pipelines, while maintaining high levels of security.
Translate experimental alignment research into scalable production infrastructure, including inference and model training stacks.
Design and iterate on user-facing tools and backend services to support high-quality data workflows
Partner with researchers, engineers, and program leads to shape feedback loops and model interaction paradigms
Drive infrastructure improvements that enable faster iteration and scaling across OpenAI’s frontier models, from internal research tooling all the way to production ChatGPT.
Qualifications
Minimum
Have strong software engineering fundamentals and experience building production systems at scale
Preferred
Enjoy full-stack development with end-to-end ownership — from backend pipelines to user interfaces
Are motivated by high-impact collaboration with research teams and solving novel, ambiguous problems
Are excited to shape how AI systems learn from human preferences and reflect a broad range of human values
Care deeply about inclusive tooling and building systems that enhance model safety, reliability, and usefulness
