Facilities Engineer

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. You can read more about us in this letter from our founders.

As the Facilities Engineer, you will be the primary technical bridge between our fusion demonstration system design team and the facility infrastructure. This is a high-impact role responsible for the integration of complex mechanical and electrical systems that power and support our fusion demonstration system. You will manage the interface where cutting-edge science meets industrial-scale engineering, overseeing design consultants to develop bespoke hardware and ensuring the facility's infrastructure is perfectly synchronized with the machine’s operational requirements. This position is based in San Leandro, California, and will require up to 25% travel to our Los Lunas, New Mexico facility for the first 2 years to embed with the design team during the critical engineering phase. The role will transition to Los Lunas, New Mexico in 2028, after which the expectation is relocation to New Mexico or near 100% presence in New Mexico.

• Oversee the interface between the fusion demonstration system design and the facility infrastructure, ensuring M&E systems (power, cooling, and utilities) meet stringent scientific requirements

• Manage relationships and technical deliverables with external design consultants to develop large-scale mechanical and electrical hardware supporting the system

• Work with the Infrastructure Design Team to ensure facility systems are documented and designed appropriately for permitting, construction, and long-term operations

• Support the physical assembly and construction of the fusion demonstration system, coordinating the installation of critical subsystems within the facility

• Support the development of utility systems including high-voltage electrical distribution, specialized cooling loops, and vacuum system infrastructure

• Support the commissioning and transition of building systems from construction into full-scale research operations

What You Bring

• Minimum BS in Mechanical or Electrical Engineering (Dual-discipline familiarity is a significant plus)

• 10+ years of experience in the design, construction,
