About the team + role

We are building an elite team, applying frontier technologies to the world’s biggest financial problems. We’re looking for bold thinkers. Sharp problem-solvers. Builders who are wired to make an impact. Robinhood isn’t a place for complacency, it’s where ambitious people do the best work of their careers. We’re a high-performing, fast-moving team with ethics at the center of everything we do. Expectations are high, and so are the rewards.

The AI Infrastructure team’s mission is to provide a robust, agile, and centralized AI platform—empowering teams across Robinhood to rapidly build, deploy, and iterate on high-quality Machine Learning (ML) and Generative AI (GenAI) applications at scale.

As a Senior Software Engineer, you’ll help evolve our ML platform and services to support scalable, reliable, and secure model development and deployment. You’ll work closely with Data Scientists and Applied ML Engineers to build foundational systems that accelerate experimentation, improve model observability, and drive business impact through AI.

This role is based in our Menlo Park, CA or Bellevue, WA office(s), with in-person attendance expected at least 3 days per week.

At Robinhood, we believe in the power of in-person work to accelerate progress, spark innovation, and strengthen community. Our office experience is intentional, energizing, and designed to fully support high-performing teams.
