TerraPower is a nuclear technology company based in Bellevue, Washington. At its core, the company is working to raise living standards globally through a more affordable, secure, and environmentally friendly form of nuclear energy along with innovations in medical isotopes to improve human health. In 2006, TerraPower originated with Bill Gates and a group of like-minded visionaries who evaluated the fundamental challenges to raising living standards around the world. They recognized energy access was crucial to the health and economic well-being of communities and decided that the private sector needed to take action and create energy sources that would advance global energy deployment. TerraPower's mission is to be a world leader in new nuclear technologies, while developing innovators and future leaders in the nuclear field. As a result, the company's activities in the fields of nuclear energy and related sciences are yielding significant innovations in the safety and economics of nuclear power, hybrid energy and medical applications -- all for significant human health benefits.

TerraPower is seeking to hire highly motivated and forward-thinking professionals who are interested in focusing on advanced nuclear reactor research and development and influencing change within the nuclear power landscape and bringing forward the critical production of medical isotopes.

Digital Twin Principal Engineer, Lead

We are seeking a Digital Twin Principal Engineer / Technical Lead to design and build the foundational architecture for our Digital Twin initiative, enabling next-generation insights across reactor design, construction, and operations. This role is responsible for translating the digital twin strategy into technical execution --- establishing system architecture, leading technical development, and building the early prototypes that will define the program's technical direction. You will lead the hands-on design and integration of high-fidelity simulation, engineering, and operational data into a cohesive digital twin ecosystem. The role requires deep technical expertise, strong systems thinking, and the ability to guide both internal teams and external partners in developing validated, scalable digital solutions for advanced nuclear systems.

Reporting directly to the Director of Digital Products and AI, you'll be part of a small, mission-driven team building foundational digital systems that will define how advanced nuclear reactors are designed, built, and operated. As one of the first technical leaders on the Digital Twin initiative, you will directly influence architecture, standards, and long-term technical direction---working alongside industry-leading engineers and partners in AI, HPC, and simulation.

Responsibilities:

• Technical Leadership
• Define and uphold the technical vision and architecture for the Digital Twin program, spanning data infrastructure, model integration, simulation, and analytics layers.
