IOS Developer

SandbaR is building a conversational interface to expand human expression. Our first products are Stream, a self extension for building ideas, and Stream Ring, the mouse for voice. Our team has built new interfaces & consumer products across Meta, CTRL-labs, Google, Apple, Fitbit, Peloton, Dior, and Equinox. If our work resonates, we would love to hear from you.

We’re looking for an experienced Staff iOS engineer to help build Stream, the bedrock of a new conversational interface. The Stream iOS app touches every aspect of our user experience; including wearable & cloud connectivity, on-device processing, UI, and more. You’ll work closely with design, firmware, and backend engineers to create a technically rigorous experience that ultimately feels simple.
