Must-haves
- 3+ years of professional ML experience (model design through operation)
- Implementation skill in Python / PyTorch, etc.
- Ability to translate problem definition into models
- A track record of going further than most people would, and the ability to explain the circumstances and your own decisions concretely (any field)
- Experience seeing something through in an unreasonable situation, or breaking through after being turned down repeatedly
- Experience building trust single-handedly with a first-time client or a senior counterpart on site

- Concrete examples of building tools or automation to spare yourself repetitive work, of fixing slowness or defects you could not leave alone, and of producing work you are proud to show others
Nice to have
- Experience with CV, drawings, and 3D data
- Experience with MLOps, distributed training, and optimization
Our strengths
- Industry focus — all-in on shipbuilding, compounding deep domain knowledge
- AI-agent native — built for real-world adoption, not PoC theater
- Speed & flexibility — a startup's agility and execution
- Social impact — solving skill succession × shorter build times
Who we're looking for
