More about this role
Artificial intelligence is rewriting every industry it touches — but construction, the second largest sector in the global economy, has barely felt it yet. That's not a problem. That's an opening. ZeroRFI is the AI company building the intelligence layer for the built environment — the platform that makes every building project smarter, faster, and more predictable than the last. We're looking for a Principal Software Engineer to architect the systems that put AI at the center of how buildings get designed, built, and operated. This isn't AI as a feature. It's AI as the foundation.
We are seeking a Principal AI Engineer - Full Stack to architect our technology foundation and lead our engineering team in building next-generation solutions for the AEC industry. You'll define our technical strategy, establish engineering excellence standards, and mentor a growing team of engineers while remaining hands-on with critical systems. This role requires both deep technical expertise and the ability to translate complex architectural decisions into practical, scalable solutions that transform how buildings are designed, built, and operated.
