Why This Role Matters

As a Sr. Manufacturing Engineer on the Pulser Module Assembly team, you'll be on the shop floor every day — owning the processes, tooling, and workflows that bring our core fusion hardware to life. You'll work alongside a small team of technicians, drive continuous improvement across the build line, and work closely with design engineering to make sure our pulser modules are built right, every time.

This is a hands-on, high-ownership role at the center of Pacific Fusion's production operations. If you thrive in a fast-moving environment where the hardware is unlike anything built before, this is your seat.

What You'll Do

  • Own end-to-end manufacturing processes for pulser module assembly, from work instruction development through build completion and acceptance
  • 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, fixturing, 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

What You Bring

  • 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

Bonus Points For

  • 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 Industrial Engineering (or equivalent experience)
