Senior Diagnostics Mechanical Engineer (Fusion Energy)

Location: Devens, Massachusetts, US; onsite

Salary: USD 134,000–205,000 per year

Company

hirify.global is developing commercially viable fusion power plants and assembling the SPARC high-field tokamak to demonstrate net fusion energy.

What you will do

• Shepherd approximately 40 SPARC diagnostic subsystems through mechanical design closeout, analysis, procurement, testing, and installation.
• Integrate technical input from scientists, designers, analysts, and engineers so diagnostic systems withstand harsh environments and support SPARC’s scientific mission.
• Coordinate with manufacturing engineers on build and test strategies for complex integrated systems.
• Support field builds and installation while maintaining quality and execution speed.
• Contribute to a strong safety culture.

Requirements

• Bachelor’s degree in mechanical, aerospace, civil, nuclear, or another relevant engineering field.
• 5+ years of relevant experience designing and delivering mechanical systems.
• Demonstrated cradle-to-grave mechanical design delivery involving nuanced environmental or performance requirements.
• Experience designing for manufacturing and assembly and collaborating with partners on integrated builds.
• Ability to apply engineering intuition, technical rigor, first-principles reasoning, and engineering–physics tradeoff analysis to create robust designs.
• Strong communication skills for gathering inputs and distributing information across partner teams.
• Ability to occasionally lift up to 50 lbs and perform extended climbing, typing, standing, or sitting.
• Willingness to occasionally travel or work required nights, weekends, or on-call shifts.
• Ability to work in a facility with industrial hazards including heat, cold, noise, fumes, strong magnets, lead, high voltage, high current, pressure systems, and cryogenics.

Nice to have

• Experience with Siemens NX, Teamcenter, or Ansys.
• Software development experience, particularly in Python.
• Experience designing large equipment requiring lifting or rigging tools for assembly.
• Experience designing systems exposed to high stress, ultra-high vacuum, high temperature, high magnetic fields, or radiation.

Culture & Benefits

• Fast-paced environment guided by integrity, execution, impact, and self-critique.
• Integrated collaboration with fusion scientists and engineers across diagnostic systems.
• Commitment to diverse perspectives and equal opportunity employment.
• Employment is contingent on compliance with U.S. Export Control Laws governing controlled or protected technologies and information.
