Why work at Sandbar
- Mission-Driven & Cutting-Edge: The opportunity to work on a genuinely new computing paradigm—a conversational interface that could fundamentally change how people interact with technology in their daily lives.
- Talent Density & Pedigree: The team is small (16 people) but composed of engineers and operators from top-tier companies like Meta, Apple, Peloton, and Equinox, offering a high-velocity, high-impact environment.
- Full-Stack & Multi-Disciplinary: Engineers and designers work across a wide stack (hardware, firmware, software, ML, AI) on challenging real-time problems.
- Culture: The company describes itself as "small," with a focus on speed, iteration, and craft. The founders are active and visible, sharing the company’s technical philosophy publicly.
- Location & Flexibility: The company is headquartered in New York City (HQ) with a presence in Germany. While office presence is implied (hardware development), there is a distributed element to the team. Perks or specific policy (remote/hybrid) are not explicitly stated but are likely high-flexibility given the small team and talent profile.
