Senior Controls Infrastructure 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.

We are looking for a Senior Controls Infrastructure Engineer to design, deploy, and operate the network, storage, and compute infrastructure supporting our facility's 24/7 operations. This is a regulated environment where security and segmentation are design requirements from day one.

• Lead the design, implementation, and optimization of the facility infrastructure network and data storage architecture, spanning on-premises systems, cloud integrations, and remote connectivity.

• Design network segmentation and Zero Trust access patterns for scientific equipment and data management systems.

• Own performance, availability, and security of facility systems for 24/7 operations, including monitoring, backup, recovery, and capacity planning.

• Implement infrastructure controls consistent with NIST SP 800-171 and applicable export control regulations (ITAR/EAR) in partnership with the IT and security teams, and support risk assessments and audits.

• Provide hands-on technical leadership: mentor a small team as it grows, partner with scientific, facility, and corporate IT stakeholders, and manage vendors and procurement for facility infrastructure.

What You Bring

• 6+ years in network or infrastructure engineering with direct ownership of production network architecture at facility or campus scale, including routing, switching, firewalls, and segmentation.

• Experience supporting 24/7 operational environments with defined availability targets, including cloud networking and hybrid connectivity.

• Ability to lead projects end to end: requirements, design, deployment, verification, documentation.

Bonus Points For

• Experience in research, energy, or other high-consequence environments, lab or scientific equipment networks (instrument connectivity, OT/IoT segmentation), NIST SP 800-171 or CMMC exposure, professional-level certifications such as Security+, CCNP or equivalent, and infrastructure automation (IaC, configuration management).
