About The Role

We're seeking a contractor to run technical feasibility experiments during a transitional period.

Design and execute rapid technical feasibility experiments (hours to days, not months)
Build lightweight prototypes to validate technical assumptions
Evaluate and advise on technology choices, architecture approaches, and feasibility
Document findings and recommendations clearly for non-technical stakeholders
Move quickly and pragmatically - optimize for learning, not perfection

What You’ll Bring

Required Experience & Skills

Prototyping speed: 5+ years of hands-on engineering experience with a track record of building quickly
Technical breadth: Comfortable across the stack. You don't need to be expert in everything, but you should be able to evaluate feasibility across frontend, backend, databases, APIs, and third-party integrations
AI fluency: Experience with LLMs, AI APIs, and modern AI-powered development tools
Startup context: Previous experience in early-stage environments where speed and pragmatism matter
Communication: Ability to translate technical findings into clear recommendations for product partners Ideal Candidate Has:
Worked as a founding engineer, first technical hire, or in rapid R&D environments
Built disposable prototypes to answer "can we build this?" questions
Comfort with ambiguity and incomplete requirements
