Pacific Fusion was founded in 2023 with the mission to power the world with abundant, affordable, clean energy. Backed by General Catalyst and Lightspeed.
About the role
Pacific Fusion is seeking a Senior Mechanical Engineer to lead the mechanical design, structural analysis, and physical implementation of core components and assemblies for our nuclear fusion demonstration system. In this role, you will take ownership of complex hardware from concept through detailed 3D CAD modeling, rigorous structural analysis, and final system integration.
What they're looking for
- Bachelor’s Degree in Mechanical Engineering required, Master’s or PhD is a plus
- 5+ years of hands-on experience in mechanical design and structural/thermal analysis for complex hardware systems
- Advanced proficiency in 3D CAD modeling software (e.g., Creo, SolidWorks)
- Extensive practical experience applying Finite Element Analysis software (e.g., ANSYS, Abaqus, or Creo Simulate) to evaluate stress, fatigue, thermal effects, and structural integrity
- Deep understanding of GD&T (ASME Y14.5), tolerance stack-up analysis, and material selection for demanding environments
- Strong knowledge of advanced manufacturing techniques (machining, additive manufacturing, precision welding) and DFM/DFA principles
More about this role
Pacific Fusion was founded in 2023 with the mission to power the world with abundant, affordable, clean energy.
We are rapidly designing and building a pulser-driven inertial fusion system to achieve net facility gain (more fusion energy output than stored energy input). In parallel, we are developing the key components required to build affordable fusion systems.
Our plans are ambitious. We have raised over $900M so far from incredible investors, resourcing us to deliver on these plans. We are bringing together the best scientists, engineers, and operators from the fusion community, hard tech industry, and other sectors. We are united by a shared sense of urgency to provide clean power for the world, particularly managing climate change while meeting growing global energy demand.
