Software Engineer, Security
Cursor, San Francisco, CA +1
The role
You form hypotheses about why data is helping or misleading the model, build the systems to test them, run ablations, and read the rollouts to find the bug, shortcut or mismatch behind a result. Every flaw you catch, or miss, shows up in what the next Grok models learn.
What you will do
- Build AI augmented code review to get involved in important systems at the right time
- Build a least-privilege and JIT system for cloud access that enables engineers and enforces least privileges
- Implement a safe environment for agents to engage with code
- Implement a framework for securely handling agent manipulation of user systems (e.g., MCP tool calls and command execution)
- Implement a paved road for preventing inappropriate data from being logged
What you need
Basic qualifications
- Experience building or scaling secure systems in fast-moving environments
