Associate Computational Scientist

We are looking for motivated early-career scientists who are excited to contribute across both theoretical and experimental efforts in a fast-paced fusion startup environment. 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. The Associate Scientist will support ongoing research and development activities related to plasma physics, fusion systems, diagnostics, and modeling. This role is designed for recent graduates with a strong foundation in physics and computational experience. The ideal candidate is curious, collaborative, adaptable, and eager to work across multiple technical areas.
