Job Description

What You Will Be Doing: 

As a Diagnostics Engineer on the Science team at Helion, you will help advance the design and development of next-generation diagnostic instrumentation that supports our mission to achieve fusion energy. Sitting at the intersection of mechanical design, prototyping, and scientific exploration, you'll transform early-stage concepts into robust mechanical systems that enable groundbreaking plasma diagnostics and research. This is an onsite role that reports directly to the Director of Experimental Science at our Everett, WA office.

You Will: 

  • Collaborate with interdisciplinary teams that include scientists, engineers, and product designers, to develop novel mechanical solutions for experimental diagnostic devices 

  • Own the mechanical design of diagnostic systems: define and refine requirements, troubleshoot hardware issues, and drive continuous improvements 

  • Design, prototype, and iterate mechanical components and assemblies using CAD tools (e.g., NX, SolidWorks); perform structural and thermal analysis (e.g., ANSYS); and lead design reviews 

  • Conduct experimental testing, collect and analyze performance data, and support root-cause analyses of mechanical failures or performance deviations 

  • Apply lessons from historical designs, develop innovative hardware, and integrate your solutions into ongoing fusion research experiments 

  • Continuously expand your skills and domain knowledge by learning from Helion’s technical experts and engaging with cutting-edge science and engineering 

Required Skills: 

  • Advanced degree in Mechanical Engineering with experience in plasma, laser, aero, or similar specialty 

  • 5+ years of hands-on industry experience with diagnostic equipment, laboratory instrumentation, precision sensing, or similar technologies 

  • 5+ years of experience with CAD software (e.g. NX, SolidWorks) and FEA software (e.g. ANSYS, FEMAP) 

  • Experience applying engineering first-principles and method-based thinking to challenging first-of-a-kind designs 

  • Hands-on exposure to a variety of engineering disciplines (mechanical, electrical, fluids)
