ML Engineer, Lead
Sandbar is seeking a Lead ML Engineer to architect, build, and deploy a new conversational interface called Stream. This role involves leading the strategy for ML-based products, designing user-facing model experiences, and optimizing inference pipelines for real-world ML deployment and human-in-the-loop agentic interactions.
Sandbar is an interface company in New York City. We aim to augment individuals so we can each think, act, and move more freely. Our team has built SW, ML, and HW products across Meta, CTRL-labs, Google, Apple, Fitbit, Peloton, and Equinox.
Our first product, Stream, is a self extension—a private voice ring and conversational interface. Stream has been featured in WSJ, Bloomberg, & Wired, and begins shipping in Summer '26.
