Principal Manufacturing Engineer

A career-defining opportunity rarely offers all of the following:

Direct connection to the mission.  Gain a clear understanding of the business and see how your work directly shapes outcomes. With no unnecessary layers, silos, or bureaucracy, every team member contributes meaningfully to the company's success and has the responsibility to drive real impact.

Growth beyond a single role.  At Boston Materials, you are not defined by your past experience or limited by a job description. Working alongside leading experts in the field, you will take on new challenges, broaden your expertise, develop new capabilities, and take ownership of projects that matter – while contributing to the broader success of the organization.

Work on problems that matter.  Help solve some of the most pressing challenges in the Advanced Semiconductor, AI Infrastructure, and Advanced Materials industries.  Boston Materials offers a rare combination of purpose, autonomy, and impact. We invite you to join us.

Boston Materials is looking for a Principal Manufacturing Engineer to serve as the technical lead for commissioning our high-volume manufacturing line at a pivotal moment. We are rapidly scaling our Liquid Metal ZRT thermal interface material from bench-scale to high-volume production. You'll be embedded on the shop floor and own the manufacturing process end-to-end: commissioning the line, defining the process windows and controls, and building the production and quality systems that make aggressive ramp targets achievable. You'll partner closely with our equipment and process engineering teams to turn novel materials processes into controlled, repeatable manufacturing.

This is a senior, hands-on technical role, not a supervisory one. You'll set the technical standard for how we manufacture, and you'll still be the person who responds when production needs you. The ideal candidate has been here before. They have personally navigated the move from pre-pilot to production for a novel materials process, likely with a small team, and they have the judgment to know when to build a system and when to just solve the problem in front of them. You bring a rigorous, data-driven mindset and fluency with modern manufacturing execution and statistical tools. If you want your work to directly impact one of the most critical thermal management problems facing next-generation AI infrastructure, this is the place to do it.
