How to Apply for Fullstack Engineer Safety Engineering

at Open AI

🏢 About Open AI

OpenAI is a leading AI research and deployment company with a mission to ensure artificial general intelligence benefits all of humanity. What makes OpenAI unique is its dual focus on cutting-edge AI research and real-world safety applications, creating an environment where engineers directly contribute to shaping the future of AI in responsible ways. Working here means being at the forefront of AI safety while collaborating with world-class researchers and engineers.

About This Role

As a Fullstack Engineer on the Safety Engineering team, you'll build full-stack tooling that directly improves the safety and reliability of OpenAI's models, particularly in sensitive areas like mental health and vulnerable-user protections. Your work will accelerate the team's ability to identify and fix safety issues while tightening feedback loops between policy, data, and model training cycles. This role is impactful because you'll be creating the platforms that ensure AI systems are safe for real-world deployment.

💡 A Day in the Life

A typical day involves collaborating with safety researchers to understand their tooling needs, then designing and implementing full-stack solutions using React/Python/Postgres. You might spend the morning building a new dashboard for monitoring model safety metrics, then work on backend APIs that help policy teams analyze safety data, all while participating in code reviews and safety discussions with cross-functional partners.
