Nuclearn.ai builds AI-powered software for the nuclear and utility industries - tools that keep critical infrastructure reliable, efficient, and safe. Our platform integrates AI-driven workflow, documentation, and research automation and is already used at 60+ nuclear reactors across North America. We’re looking for a Staff Engineer to take on the hardest technical problems across our stack and help scale our systems, reliability, and security. This is a hands-on, deeply technical role for someone who can lead architecture, mentor engineers, and deliver production-grade AI in regulated environments. You’ll partner with leadership but remain an individual contributor—your impact is through technical design, code, and cross-team influence, not direct people management.
