Mechanical Engineer, Engineering Design & Technologists
Lead the design and development of groundbreaking fusion technologies that will help power the future of clean energy.
The Senior Mechanical Engineer will work closely with Realta's engineering and scientific teams to provide technical leadership, engineering expertise, and critical design input that advances Realta's technology development roadmap. This individual will play a key role in the design, development, and execution of Hammir-Realta's reactor‑scale simple magnetic mirror and primary technology development platform, and Realta's first‑of‑kind fusion pilot plant. The Senior Mechanical Engineer will be expected to drive complex engineering initiatives, mentor junior engineers, and contribute to strategic decisions that support the commercialization of fusion energy.
Realta Fusion is a rapidly growing start‑up developing compact magnetic mirror fusion energy systems to address the biggest challenge of our time - tackling global climate change while ensuring a sufficient energy supply for at least ten billion people on (and off) earth. We are building a team with diverse talents dedicated to making fusion energy a real solution to humanity’s most pressing problem.
