Engineering One - Nuclear

The Nuclear Company is the fastest growing AI tech-enabled startup in the nuclear and energy space, pioneering a fleet‑scale approach to building the next generation of nuclear reactors. Through our design‑once, build‑many model, we're accelerating the deployment of safe, reliable, and affordable nuclear energy. We operate with an AI‑first mindset. Every employee is expected to leverage AI, technology, and the Nuclear Operating System (NOS) as integral components of their role to improve the quality, speed, and impact of their work.

We expect every team member to continuously identify opportunities to automate workflows, enhance decision‑making, improve processes, and contribute to the ongoing evolution of NOS as a strategic operating capability that enables The Nuclear Company to scale with excellence. We hire people who are driven by purpose, thrive in ambiguity, and are energized by building what has never been built before.

Our team combines intellectual curiosity with high agency, embraces candid feedback and continuous learning, and holds themselves and others to exceptional standards. Our values— Transparency, Responsibility, Unity, Scrappy, and Tenacity —guide how we hire, collaborate, and make decisions every day. They are not words on a wall; they are the standard by which we operate. TRUST is the foundation of our safety culture, fostering intellectual honesty, accountability, and open communication, while our values challenge every team member to execute with urgency, humility, resilience, and an unwavering commitment to our mission.

The Engineering One Programis The Nuclear Company’s early‑career engineering program for exceptional graduating seniors who want to help build the next generation of nuclear infrastructure. We are hiring students graduating in Spring
2027for full‑time roles beginning in Summer
2027. The program provides broad exposure across the nuclear project lifecycle while building deep technical capability in an assigned discipline. Depending on your background and project needs, you may work across mechanical engineering, civil and structural engineering, construction and project delivery, nuclear licensing, systems engineering, or related technical functions.
