Research Engineer, Frontier Red Team (Autonomy)

The Frontier Red Team at Anthropic is a small, focused technical research team focused on researching and ensuring safety with self-improving, highly autonomous AI systems — especially ones with cyberphysical capabilities. As a Research Engineer, you'll build and eval model organisms of autonomous systems and develop defensive agents needed to counter them. This is applied research with real-world stakes. Note: This role is exclusively hiring in San Francisco. Salary: $320,000–$850,000 USD.

You May Be a Good Fit If You • Have strong software engineering skills, particularly in Python • Have experience building and working with LLM-based agents or autonomous systems • Are driven to find solutions to ambiguously scoped, high-stakes problems • Design and run experiments quickly, iterating fast toward useful results • Thrive in collaborative environments • Care deeply about AI safety Strong Candidates May Also Have • Experience with reinforcement learning, self-play, or multi-agent systems • Experience with robotics, hardware interfaces, or cyberphysical systems • Track record of building demos or prototypes that communicate complex technical ideas • Experience working with external stakeholders (policymakers, government, researchers)
