About Pacific Fusion

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.

Why This Role Matters

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.

What You'll Do

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, and

commissioning of large-scale industrial or scientific research facilities

Proven track record managing complex M&E infrastructure, including

high-voltage power, process piping, and industrial cooling

Significant experience managing engineering consultants and large-

scale hardware procurement contracts

Proactive, "DOer," and self-starter capable of navigating the ambiguity

of a first-of-a-kind research project

A positive attitude and the ability to influence cross-functional teams of

scientists, engineers, and contractors

Bonus Points For

Previous experience at a National Laboratory (e.g., SNL, LANL, LLNL)

or similar highly-regulated research environments

Experience overseeing construction or facilities involving radiological

shielding, hot cells, or other high-energy physics hazards

Knowledge of pulsed-power infrastructure, ultra-high vacuum (UHV)

environments, or cryogenic systems

PE (Professional Engineer) license
Experience working closely with PhD scientists and R&D organizations

to translate theoretical needs into physical hardware

Pay Range:

$138,100—$207,100 USD
