About Pacific Fusion

Pacific Fusion was founded in 2023 with the mission to power the world with abundant, affordable, clean energy.

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.

This role is critical to transitioning prototypes components to production into our pulser systems.

• Own end-to-end manufacturing processes for pulser module assembly, from work instruction development through build completion and acceptance
• Manage the transition of new electrical components from the design and prototyping phase into full-scale production and integration for new product introduction
• Work alongside the technicians to provide fast solutions that can be quickly executed to keep the build progressing
• Support documentation handoff to the production team for the build processes as well as issues and their respective resolutions
• Manage build schedule using microsoft project to communicate within the company
• Partner with design engineering to provide manufacturing feedback, drive DFM improvements, and support first article builds
• Identify and resolve production non-conformances, leading root cause analysis and implementing corrective actions to prevent recurrence
• Define and develop tooling, fixtures, and equipment requirements to support safe, efficient, and repeatable assembly operations
• Track and report production metrics — cycle time, yield, first pass rate — and drive initiatives to hit and exceed targets
• Support the scale-up of assembly operations as Pacific Fusion transitions from low-rate initial production to higher volume output
• Support schedule management by clearly defining steps to completion

• 3–7 years of manufacturing or process engineering experience in a hands‑on production environment
• Demonstrated experience leading or mentoring technicians on a production floor
• Strong understanding of mechanical assembly processes, work instruction development, and production documentation
• Hands‑on experience with complex electromechanical assembly — high voltage, pulsed power, precision mechanical, or similarly demanding hardware preferred
• Familiarity with quality management systems, non-conformance processes, and root cause analysis methodologies (8D, 5‑Why, Fishbone)
• Ability to read, interpret, and create engineering drawings, schematics, and GD&T
• Comfortable working in an early‑stage, fast‑moving environment where processes are still being defined
• Hands on experience working at a startup building the prototype units
• Familiarity with standard machining processes and capable of running equipment

• Experience in aerospace, defense, energy, or other high‑complexity hardware industries
• Familiarity with Lean manufacturing, Six Sigma, or other continuous improvement frameworks
• Experience supporting first‑of‑kind or prototype‑to‑production transitions
• Exposure to high voltage or pulsed power systems
• BS in Mechanical, Manufacturing, Electrical, or…
