Principal, Analysis/Systems Engineering

Own the system-level vision that turns first-of-a-kind fusion hardware into a cohesive, scalable reality—leading the integration of breakthrough science and engineering on the path to commercial fusion energy. The Head of Systems Engineering will lead the systems engineering function at Realta Fusion,  establishing technical requirements, driving system integration, and ensuring our magnetic mirror fusion devices meet performance, safety, and operational  objectives . This senior technical leadership role demands  expertise in complex system architecture, requirements management, and integration of multidisciplinary subsystems. You will bridge plasma physics, mechanical, electrical, nuclear, and  controls engineering teams to ensure coherent system design and successful execution from experimental devices through commercial deployment. The ideal candidate combines deep systems engineering  expertise with strategic leadership, thriving in a first-of-a-kind hardware environment where disciplined systems thinking directly  impacts our ability to deliver commercial 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 .
