Founding AI Engineer at Semble AI

We're building AI agents that design building-systems (fire, HVAC, plumbing, security) instantly and code-compliantly. The $600B building-system integration industry still runs on spreadsheets and manual drawings, even as building codes rapidly evolve and become more localized. It’s a massive blind spot for the tech world. We are transforming building-system design from a months-long, error-prone process into an instant, automated workflow. Semble AI is becoming the industry standard for top quality commercial building design. As a founding engineer, you’ll work directly with the founders to own and build systems such as: Vision pipelines that segment rooms, walls, and architectural elements from noisy PDFs/CAD files LLM + RAG workflows that interpret building codes and produce compliant designs Full-stack features across our React/Node/Postgres platform You’ll have massive ownership and help set the technical direction of a company in a market that’s about to undergo a once-in-a-generation transition. Typescript / React / Node / Express / PostgreSQL Python (PyTorch, NumPy, etc.) Vision models : object detection, instance + semantic segmentation AI Agents: multi-agent reasoning, wo
