AI Evaluation & Model Risk Lead @ Bellevue WA

Title: AI Evaluation & Model Risk Lead

Location: Bellevue WA

Engineer, AI — AI Evaluation & Model Risk Lead

Are you ready to join the Un-carrier movement?

This role leads how T-Mobile decides which AI models it can trust — the behavioral and model-risk evaluation that lets teams adopt new models fast and with evidence. You'll own model risk end to end: the initial clearance that gates a model into use, the ongoing evaluation that re-checks it on every version change and watches it in production, and the model cards that make the results durable — what was tested, what it's cleared for, and where its risks sit. Your scope is every model the enterprise makes available to use or build on: the models in our GenAI tools (Claude, OpenAI, Glean), the model gardens in Bedrock and other clouds, and models that come through SaaS platforms. You'll build and run the evaluation harness to the bar Safety Standards sets, alongside Cyber — who owns the security testing — and Responsible AI. Success looks like teams getting cleared access to new models quickly because the risk is measured, documented, and current.

If you want to help bring AI to T-Mobile in a way that's fast, safe, and easy to use, we'd like to hear from you.
