For unincorporated Los Angeles County workers: we reasonably believe that criminal history may have a direct, adverse and negative relationship with the following job duties, potentially resulting in the withdrawal of a conditional offer of employment: protect computer hardware entrusted to you from theft, loss or damage; return all computer hardware in your possession (including the data contained therein) upon termination of employment or end of assignment; and maintain the confidentiality of proprietary, confidential, and non-public information. You will investigate how misaligned behavior emerges across extended trajectories - including when models persist toward the wrong objective, take unsafe shortcuts, lose track of instructions, exploit weaknesses in their environment, or circumvent constraints - and translate these insights into behavioral policies, evaluations, monitoring, and safeguards.

The job rewards a founder mentality and extreme ownership, including going into unfamiliar domains, from chemical engineering to complex legal logic, and getting to ground truth fast on problems others have written off. Partner with the world’s most advanced AI research teams on datasets and benchmarks that shape how frontier models behave, focused on alignment, safety, and reward signal design.

Member of Technical Staff, Research

Over time, optimization should become a repeatable operating loop: production traces reveal failure modes; failure analysis generates candidates; evaluations identify promising changes; controlled rollouts validate them; and production feedback informs the next iteration. Build and operate systems that continuously search for better AI configurations across prompts, model selection, routing, reasoning budgets, context construction, tool use, agent workflows, retries, caching, parallelism, and workflow-specific policies.
