Benefits
  • Competitive Compensation & Meaningful Equity: We value talent and back it with fair, founder-level alignment. You’ll own a real stake in the company’s future.
  • High-Impact, High-Ownership Role: You won’t be a cog in the machine. You’ll own initiatives end-to-end and help shape the core of our AI stack and company direction.
  • Work Directly with the CEO & Founding Team: Collaborate daily with the CEO and technical leadership to drive product, strategy, and long-term vision.
  • Build What Doesn’t Exist (Yet): We’re working on first-principle AI infrastructure that doesn’t exist elsewhere. If you’re here to do original, meaningful work — this is it.
  • Zero Bureaucracy, Maximum Autonomy: We move fast, stay lean, and keep decision-making close to the builders. Your input drives the roadmap.
  • Flexible, But In-Person Matters: We’re remote-first, but we believe in the power of face-to-face time. We hold monthly gatherings/hackathons in SF and Europe, to stay aligned and build real momentum together. Results still matter more than hours — but we show up when it counts.
