Descripción del empleo

At Valar Atomics, we're redefining what's possible in energy. Our mission is to make clean, high-temperature nuclear power scalable—unlocking abundant energy for industry, hydrogen, and next-generation manufacturing. We are a team of builders, engineers, and operators who believe nuclear energy should be fast to deploy, factory-made, and built for the real world. Our first pilot plant in Orangeville, Utah will demonstrate how advanced nuclear systems and fuel fabrication can power the future. Joining Valar Atomics means becoming part of a company where autonomy, ownership, and impact exist at every level.

The Team

As part of the Engineering organization, Power Con v ers ion develops the technologies that efficiently transform reactor-generated heat into usable electrical power . The team focuses on maximizing system performance, reliability, and commercial viability.

The Role

Valar Atomics is seeking a turbomachinery aerodynamics engineer to join the turbomachinery team and advance power generation capability. In this role, you’ll be responsible for thermal analysis of cutting edge turbomachinery rotors and static structures. You’ll be working with cross-functional team members to define a high efficiency, highly producible cycle design. As an early hire in turbomachinery, you will be able to directly influence design decisions on the system architecture.

Key Responsibilities

• Analyze rotating and static components to define their maximum operating temperature
