• Experience mentoring technicians on a production floor.
• Ability to read engineering drawings, schematics, and GD&T.
• Strong knowledge of mechanical assembly processes and documentation.
• Familiarity with quality systems and non-conformance processes.
• Experience with high voltage/pulsed power hardware is a plus.

Responsibilities

• Own end-to-end manufacturing processes for pulser module assembly from instructions to acceptance.
• Manage transition of new components from design to production for NPI.
• Work with technicians to provide fast solutions to keep builds progressing.
• Support production docs handoff and issue resolution.
• Manage build schedule using Microsoft Project and communicate across teams.
• Provide manufacturing feedback to design engineering and drive DFm improvements.
• Identify root causes of non-conformances and implement corrective actions.
• Define tooling, fixtures, and equipment requirements for safe, repeatable assembly.
• Track production metrics and drive initiatives to hit targets.

Job description

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

This role will drive transitioning prototype components to production-ready pulser systems.

What You'll Do

• Own end-to-end manufacturing processes for pulser moduleassembly, from work instruction development through buildcompletion and acceptance
  
• Manage the transition of new electrical components fromthe design and prototyping phase into full-scale productionand integration for new product introduction
  
• Work alongside the technicians to provide fast solutions thatcan be quickly executed to keep the build progressing
  
• Support documentation handoff to the production team forthe build processes as well as issues and their respectiveresolutions
  
• Manage build schedule using Microsoft project to communicate within the company
  
• Partner with design engineering to provide manufacturingfeedback, drive DFM improvements, and support first articlebuilds
  
• Identify and resolve production non-conformances, leadingroot cause analysis and implementing corrective actions toprevent recurrence
  
• Define and develop tooling, fixtures, and equipmentrequirements to support safe, efficient, and repeatableassembly operations
  
• Track and report production metrics — cycle time, yield, firstpass rate — and drive initiatives to hit and exceed targets
• Support the scale-up of assembly operations as PacificFusion transitions from low-rate initial production to highervolume output
  
• Support schedule management by clearly defining steps tocompletion

What You Bring

• 3–7 years of manufacturing or process engineeringexperience in a hands-on production environment
  
• Demonstrated experience leading or mentoring technicianson a production floor
  
• Strong understanding of mechanical assembly processes,work instruction development, and productiondocumentation
  
• Hands-on experience with complex electromechanicalassembly — high voltage, pulsed power, precisionmechanical, or similarly demanding hardware preferred
  
• Familiarity with quality management systems, non-conformance processes, and root cause analysismethodologies (8D, 5-Why, Fishbone)
  
• Ability to read, interpret, and create engineering drawings,schematic, and GD&T
  
• Comfortable working in an early-stage, fast-movingenvironment where processes are still being defined
  
• Hands on experience working at a startup building theprototype units
  
• Familiarity with standard machining processes and capableof running equipment

Bonus Points For

• Experience with a focus on vacuum seals and systems, including rough, high, and ultra-high vacuum environments
• Experience in aerospace, defense, energy, or other high-complexity hardware industries
  
• Familiarity with Lean manufacturing, Six Sigma, or othercontinuous 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 IndustrialEngineering (or equivalent experience)
• Experience using CREO
