SOFTWARE ENGINEER, SECURITY

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.

RESPONSIBILITIES:

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

Strong opinions on secure defaults, but can balance pragmatism with rigor
Enjoy working on small, high-talent teams where impact is magnified
Motivated by protecting developers and users, and you see security as an enabler
