Associate Computational Scientist

About the role

Realta Fusion is a rapidly growing start‑up developing compact magnetic‑mirror fusion energy systems to address global climate change while ensuring a sufficient energy supply for at least ten billion people. 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, who are curious, collaborative, adaptable, and eager to work across multiple technical areas.

Responsibilities

• Perform simulations to answer key questions about plasma dynamics in magnetic mirror traps.
• Assist in the development of modeling infrastructure to accurately reproduce experimental observations.
• Support analysis and interpretation of simulation and experimental data using scientific programming tools.
• Collaborate with scientists and engineers across theory, experiments, controls, and systems teams.
• Maintain clear documentation of research activities and results.
• Participate in technical discussions and project‑planning activities.

Qualifications

Required:

• BS in Physics or a closely related field.
• Strong foundation in classical physics, electromagnetism, and modern physics.
• Exposure to both theoretical and experimental physics through coursework, research, or internships.
• Experience with scientific programming and data‑analysis tools (Python, Julia, or similar).
• Strong problem‑solving and communication skills.
• Ability to work effectively in a collaborative, multidisciplinary environment.

Preferred:

• Undergraduate research experience in plasma physics, fusion, electromagnetics, or related fields.
• Familiarity with numerical methods or simulation tools.
• Experience using high‑performance computing clusters.
• Experience working in team‑based research environments.

Benefits

• Competitive compensation package, including equity stock options.
• Comprehensive health, dental, and vision insurance, plus a 401(k) plan.
• Flexible paid time off (PTO) to support work‑life balance.
• Opportunity to work and live in Madison, Wisconsin—a highly livable and vibrant city.
