Mechanical Engineer - Pulsed Power

Why This Role Matters

We are seeking a highly motivated Mechanical Engineer to design, build, operate, and advance our pulsed power systems - the core of our experimental fusion platform. This role is deeply hands-on and multidisciplinary, requiring expertise across high-voltage systems, controls, diagnostics, and data analysis. The ideal candidate combines strong technical depth with the ability to lead R&D workflows, collaborate across disciplines, and take ownership of system performance and development.

• Design, build, and operate pulsed power systems, including high-voltage and high-current architectures, control systems for pulsed power operation, safety, and automation.
• Operate pulsed power systems during testing and data acquisition campaigns, including occasional work outside regular business hours.
• Ensure safe, reliable operation of high-energy systems in accordance with company safety protocols.
• Acquire, process, and analyze data from pulsed power experiments to evaluate system performance and stability.
• Develop tools and workflows for data collection, visualization, and interpretation.
• Translate experimental results into actionable insights for next-generation pulser design.
• Take ownership of pulsed power subsystem advancement and roadmap execution.
• Lead design reviews, experimental planning, and technical documentation.
• Collaborate with mechanical, electrical, and plasma physics teams to iterate and improve designs.
• Drive continuous improvement in reliability, efficiency, and diagnostic capability.

What You Bring

• Bachelor's degree in Mechanical Engineering, Applied Physics, or a related field.
• 2+ years of demonstrated experience designing complex systems.
• Experience designing, developing, testing and building prototype mechanical/electrical systems.
• Proven ability to deliver complex R&D projects on schedule, from concept to prototype to validation.
• Strong background in electronic design, control systems, and PLC software development.
• Proficiency in circuit simulations (e.g., SPICE, PSCAD, COMSOL, or similar) and data analysis using Python, MATLAB, or equivalent tools.
• Familiarity with engineering modeling and CAD software (e.g., SolidWorks, ANSYS, or COMSOL Multiphysics).

Bonus Points For

• Advanced degree (M.S. or Ph.D.) in Mechanical Engineering, Applied Physics, or a related field.
• Prior experience with high-voltage pulsed systems for fusion, plasma research, or accelerator applications.
• Hands-on experience integrating diagnostics and controls for high-energy experiments.
• Knowledge of safety standards and best practices in high-voltage or high-energy environments.
