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 Senior 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 Albuquerque, NM, and will require up to 50% travel to
our San Leandro, CA facility for the first year to embed with the design team
during the critical engineering phase.

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:
$120,000$170,000 USD
