About Sandbar

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.

Join us in creating technology that extends human thinking.

About

We’re looking for an experienced software product engineer to help build Stream, a new conversational interface. We aspire to make technology as easy as thinking—fast, intuitive, and always available. This role will extend Stream to new surfaces and use cases, and is perfect for someone who sits at the intersection of software engineering, interaction design, and consumer products.

• Collaborate with iOS, firmware, and backend engineers to maintain a seamless cross-platform experience

• Work with product, design, and GTM to ship releases, gather insights, and iterate

Qualifications

• 3+ years building and shipping consumer-facing software products

• Strong proficiency in modern web technologies (TypeScript, React or similar) and desktop frameworks (Swift, Electron)

• Comfort working across the stack—backend services, APIs, and frontend

• Track record of building 0-to-1 products or features with ambiguity

• Excellent attention to interaction details

• Experience with real-time or interactive applications is a plus

• Experience with audio/media APIs is a plus

• Strong interdisciplinary communication

• Strong ownership, comfort with ambiguity, and high technical output

• Passion for human-computer interfaces
