Mechanical Engineering Manager

What You Will Be Doing:

You will lead the thermo-mechanical hardware design efforts for Helion's fusion devices. Your role will focus on solving complex, high-impact problems that influence system performance, while also growing a high-performing engineering team. You will establish technical standards, drive execution, and shape design processes to increase the speed and quality of innovation. You will report to the Senior Manager of Mechanical Engineering and this is an onsite role located at our Everett, WA office.

You Will:

• Grow and mentor a team of multidisciplinary thermo-mechanical engineers
• Oversee the design, development, and optimization of thermal management strategies across the machine
• Drive high-level architectural decisions on thermal processes, energy recovery, and plant design schemes
• Lead validation of thermal models through subscale testing, instrumentation design, and correlation of experimental data
• Drive integration of thermal subsystems within vacuum environments, cryogenic systems, and high-heat-flux components

Required Skills:

• Bachelor's degree in Engineering
• 5+ years of thermal/mechanical engineering experience, including 2+ years in an engineering management role
• Demonstrated ability to hire and grow engineers providing impactful career development
• Experience leading multidisciplinary teams with full-scope project ownership
• Proven ability to manage complex engineering projects with schedule accountability
• Hands-on exposure to multiple engineering disciplines such as mechanical, thermal, and fluids
• Ability to apply engineering first-principles and structured problem-solving to technical challenges
