Founding Engineer (Applied AI)

About the Role This is a founding engineering role at an early-stage AI startup applying computer vision and large language models to automate blueprint analysis and cost estimation in construction. You'll own the intelligence layer — building and shipping CV/ML systems that real users rely on — as a core member of a small, high-impact team. What You'll Do Drive R&D and development on the intelligence layer, not the application layer. Apply cutting-edge computer vision, LLM, and AI systems to real construction workflows. Ship working prototypes quickly, then iterate based on direct user feedback. What We're Looking For Hands-on applied CV/ML experience with Python, machine learning, deep learning, and computer vision. Demonstrated 0-to-1 builder who has shipped AI to production. Growth mindset — you prioritize trajectory and learning over credentials. Clear, empathetic communicator who is honest about what's working and what isn't. Comfortable doing "schlep" work — whatever it takes to move an early-stage product forward. US citizenship required (no visa sponsorship available). Bonus: experience building a product people used or paid for (founder or early startup experience). Bonus: background in construction or construction technology. Compensation & Benefits Base salary $120,000 – $180,000 USD annually. Equity offered as part of the founding team package. No visa sponsorship available. Location On-site, full-time in San Francisco, CA. Candidates must be based in SF or willing to relocate.
