Sr. Staff Machine Learning Systems Engineer
Hims & Hers, US - Remote
The role
How do we make advanced AI/ML not just powerful but trustworthy enough to run in a regulated healthcare environment? We're looking for a Senior Staff engineer who can own that question end to end: the data pipelines that feed our models and evaluations, and the evaluation infrastructure — judges, scorers, statistical regression gates, red-team testing — that decides whether AI models are effective and safe to ship to patients.
This is a leadership role for someone who works comfortably across disciplines. You'll set technical direction for how we build, version, and trust the data and judgments that our AI products are evaluated against. Your scope will expand from raw data ingestion and feature/dataset pipelines, through evaluation methodology and statistical rigor, to the reporting surfaces that let clinical and product teams act on what we learn.
