Senior Full-Stack Engineer (Generalist)

What you'll do

• Build, harden, and deploy features across the entire stack — data and geometry processing through to the interfaces our customers and internal teams use.
• Take real ownership of features from start to finish, while staying flexible enough to jump in and help anywhere so we're never blocked on a single contributor.
• Help shape and execute the product roadmap, and contribute directly to product intuition — not just implement tickets.
• Work closely with other engineers and interface with the business to understand requirements and priorities.
• Help define our engineering process as we grow, in a team that ships to production weekly.

Must-haves

• U.S. citizenship (required).
• This role works with sensitive government Controlled Unclassified Information (CUI) and is subject to government contract requirements.
• In San Francisco, in person — 3–4 days/week at our co-working space (Friday remote optional).
• Startup-pace mindset — comfortable prioritizing product velocity over stability while we move fast.
• Strong CS fundamentals — data structures, algorithms, and systems design.
• A real debugging and problem-identification approach — you can find and reason through the root cause yourself, not just produce AI-assisted output.
• Sound judgment with AI tooling — you use AI tools to go faster without over-relying on them.
• Domain fit (strongly preferred): Experience with 3D analysis, CAD models, the software/hardware interface, or manufacturability.
• Direct experience is exceptional; strong, genuine interest is acceptable.
• Comfort owning features across every layer of the stack and shipping production code at a fast cadence.

Communication & culture

• Can explain technical work clearly to a non-technical person — this is a key culture-fit signal for us.
• Strong communication, organization, and a thoughtful problem-solving approach.
• You thrive in a lean, high-ownership environment with minimal structure.

Nice to have

• Familiarity with 3D printing and CAD/manufacturing file formats (STL, STEP, OBJ, and friends).
• Exposure to defense or government work — familiarity with secure data environments and procurement-ready outputs is a plus, though not required.
