Nuclear Engineer I

The Nuclear Company is the fastest-growing AI-enabled startup in nuclear energy, bringing together experienced nuclear professionals, technologists, engineers, and builders to deliver the next generation of nuclear power. Through our design-once, build-many approach, we are creating a repeatable model for deploying nuclear fleets—combining the industry’s highest standards for safety, quality, and regulatory rigor with the speed and innovation required to meet the world’s growing energy needs. We are building the future of nuclear work. Every employee is expected to use AI, technology, and our Nuclear Operating System (NOS) to strengthen engineering and operational decision-making, improve quality, eliminate inefficiencies, and accelerate execution without compromising safety. Our nuclear expertise shapes the continued evolution of NOS, enabling us to capture institutional knowledge, standardize best practices, and deliver complex projects with greater consistency and certainty. We hire people who believe nuclear energy is essential to human progress. Our team is made up of mission-driven experts who respect the rigor of the industry while challenging outdated ways of working. They bring deep technical judgment, intellectual curiosity, high agency, and the humility to learn from others. Our values— Transparency, Responsibility, Unity, Scrappy, and Tenacity —guide how we hire, collaborate, and make decisions. Together, they form TRUST , the foundation of our safety culture and our commitment to intellectual honesty, personal accountability, open communication, and operational excellence. About the role The Engineering I Program is 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 i n Spring 2027 for full-time roles beginning in Summer 2027 . Engineering One is designed for engineers who want more than a traditional entry-level position. Participants will work alongside experienced engineers, constructors, licensing professionals, project leaders, and Members of Nuclear Staff on real problems tied directly to the development and deployment of nuclear projects. 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, Supply Chain and Procurement, systems engineering, or related technical functions . From your first day, you will be expected to learn quickly, ask good questions, work rigorously, and contribute to meaningful work. Responsibilities Engineering I participants will typically begin in one of the following areas while gaining exposure to the broader nuclear project lifecycle. Mechanical Engineering You may contribute to: Mechanical systems and equipment used in nuclear and conventional power facilities Piping, pumps, valves, heat exchangers, pressure vessels, and rotating equipment System design and engineering calculations Equipment specifications and vendor technical evaluations Piping and equipment layout Thermal-hydraulic and mechanical analysis Design reviews and interdisciplinary coordination Equipment installation, testing, startup, and commissioning <span data-contras
