Senior Manufacturing Engineer

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)
