Principle Manufacturing Engineer

Principal Manufacturing Engineer

Cooling performance limits AI infrastructure, semiconductor equipment, photonics, power electronics, defense systems, and other high‑powered compute applications. The Stack Forging™ process creates single‑piece, leak‑tight metal parts with complex internal microgeometries for stronger cooling performance, lower pressure drop, and high reliability.

This role generally requires 4 days onsite per week.

• Manufacturing system design: Design, develop, and commission scalable assembly systems for high‑volume thermal system production.
• Testing system development: Develop and implement automated testing systems (e.g., performance, reliability, and leak testing) for cold plates and thermal systems.
• Vendor selection and management: Own the technical selection, procurement, and qualification of high‑value capital equipment required for automated testing and assembly.
• Program management: Lead the manufacturing scale‑up project for thermal system production, including defining resourcing, setting timelines, and establishing milestones.
• Technical leadership: Act as a subject matter expert on manufacturing for cold plates and thermal systems. Set and maintain the technical standards for manufacturing quality, process control (e.g., PFMEAs), and reliability.
• Mentorship: Mentor and provide technical guidance to junior engineers, production engineers, and production staff.

You are a seasoned manufacturing professional and take pride in the quality and reliability of the system you build. You are driven and hands‑on, and can confidently navigate the question of what to build yourself and what to outsource. You want to know how the systems you are responsible for work, because you believe that is the only way to know that you’ve done things correctly.

• Bachelor’s degree in Mechanical, Industrial, or a related Engineering field.
• 8+ years of experience in manufacturing.
• 3+ years of experience with commissioning capital equipment.
• 2+ years of experience with thermal‑fluid systems.

• Proven expertise with Lean Manufacturing principles.
• Direct experience with metal joining and fitting processes, preferably in a thermal management context.
• Experience in high‑volume mass production environments (e.g., automotive, consumer electronics, or high‑power computing/data center).
• Experience working in a fast‑paced, high‑growth startup environment.
• Proficiency with 3D software tools for design, inspection, or CAM.
