Infrastructure Mechanical 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 Infrastructure Mechanical Engineer, you will be responsible for overseeing the integration of mechanical building system requirements for our nuclear fusion demonstration system. You will work across several teams to develop the building systems which enables us to achieve net facility gain. During construction you will work with design consulting engineering and contractors to ensure a quality installation which can be safely maintained. Following construction, you will be responsible for the operation, maintenance, and future upgrades of the building systems. 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 during the design and permitting process. 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.

• Develop facility mechanical equipment requirements and guidelines for building systems including HVAC, fire protection, plumbing, and other infrastructure systems.

• Assist in the design and development of utility systems including pneumatic, fluid, and vacuum systems.

• Interface with engineers, scientists, and technicians to obtain facility mechanical inputs.

• Work with the Infrastructure Design Team to ensure building mechanical systems are documented and designed appropriately for permitting design, construction, commissioning, and operations.

• Develop building systems commissioning, maintenance, and operations plans.

What You Bring

• Minimum BS, Mechanical Engineering

• Minimum 7+ years of experience working in design, construction, facility operations, and commissioning for industrial, manufacturing, or research facilities
