Job details

Senior Mechanical Engineer - Thermal

What You Will Be Doing:

You will own thermo-mechanical hardware designs for Helion's fusion generator. You will solve multidisciplinary engineering problems that are necessary for deploying fusion energy to the world and act as a culture driver on a growing team. You will report directly to our Senior Manager of Mechanical Engineering at our Everett, WA office.

You Will:

  • Own and understand designs related to thermal, fluids, and structural subsystems – and improve their requirements.

  • Learn from historical engineering approaches, design novel hardware, and test your solutions

  • Design fusion hardware within 3D CAD software (e.g. NX)

  • Perform analysis (1D, 2D, 3D) with in-house and out-of-house tools (e.g. ANSYS) and hold design reviews to gather feedback and iterate to a fully functioning system

  • Learn from experts to expand your engineering skillset and domain knowledge

  • Work hands-on alongside experienced technicians to implement your hardware designs

  • Troubleshoot hardware issues as they arise on integrated fusion generators

Required Skills:

  • Bachelor's degree in engineering

  • 7+ years of professional experience delivering on full-scope engineering projects (including schedule ownership)

  • Experience applying engineering first-principles and method-based thinking to challenging problems

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

  • Advanced experience with CAD software (e.g. NX, Solidworks)
