- You thrive in ambiguity and can own projects with minimal guardrails from day one
- You prefer on-site, synchronous collaboration and believe in startup chaos
- You need remote flexibility or hybrid arrangements-Assembly is on-site only
- You're a specialist (pure engineer or pure marketer); this role demands T-shaped depth and breadth
