About the Role Join an early-stage construction technology team as a Founding Engineer focused on applied AI. You will build the intelligence layer behind tools that interpret construction blueprints and support faster, more affordable construction workflows. What You'll Do • Develop and improve computer vision, machine learning, and AI systems, with a focus on object detection and coordinating models. • Explore and apply current computer vision techniques, large language models, and other AI systems to practical problems. • Build and ship early prototypes quickly, then refine them using user feedback. • Contribute to pragmatic early-stage work beyond core modeling when needed. What We're Looking For • Hands-on applied computer vision and machine learning experience, including Python and deep learning; the role is open to a broad range of experience levels. • Experience building an AI system from 0 to 1 and deploying it in production. • Comfort working through ambiguous, challenging problems and taking on practical work beyond modeling. • A growth mindset and an empathetic, candid communication style. • Motivation to use AI to help make housing more affordable. • Construction or social-impact experience is useful, as is having built a product or project adopted or paid for by users. • Must be a U.S. citizen. Compensation & Benefits Salary range: $120,000 to $180,000 annually. Visa sponsorship is not available. Location Full-time, on-site in San Francisco, California.
