Résumé du poste

Boston Materials is seeking a Principal Manufacturing Engineer to lead the commissioning of a high-volume line, from installation to full production readiness. You will own process windows, QC systems, and MES/SCADA integration to support a rapid ramp of Liquid Metal ZRT materials.

The role is senior, hands-on, data-driven, and requires experience moving a materials process from pre-pilot to production, partnering with equipment and process teams to ensure robust, repeatable manufacturing.

Qualifications

• Bachelor's or Master's degree in Materials Science, Chemical Engineering, Mechanical Engineering, or related field.
• Hands-on experience taking a materials-based process from development to controlled manufacturing.
• Ability to provide day-to-day engineering support to an active line.
• Set equipment parameters and specification limits for critical-to-quality characteristics.
• Experience implementing QA/QC systems from raw material to finished product.
• Experience developing equipment qualification protocols (IQ/OQ/PQ).
• Strong SPC knowledge and data-driven problem solving.
• Proficiency with Ignition/SCADA, Tulip/MES, and statistical tools.

Responsabilités

• Act as technical owner of the manufacturing process through commissioning of the high-volume line.
• Design manufacturing and material flows with robust conformity controls.
• Establish line readiness, preventive maintenance plans, SOPs, and validated process windows.
• Determine equipment parameters and design experiments for process sensitivity.
• Translate developmental processes into controlled manufacturing while preserving intent.
• Implement MES, SCADA, and SPC for real-time monitoring and traceability.
• Lead non-conformance investigations and drive corrective actions to closure.
• Drive continuous improvement of production and quality systems.
• Provide tactical engineering support and mentor engineers on process control.

Principal Manufacturing Engineer

Own commissioning of high-volume manufacturing line from installation to full production readiness

Location: Billerica, Massachusetts

Compensation: $150,000 - 200,000 USD / year

About The Role

Principal Manufacturing Engineer

Boston Materials produces advanced materials with enhanced energy transfer properties using its patented Z-axis Carbon Fiber technology. The Company's products solve critical performance bottlenecks in applications spanning thermal, electrical, and structural use cases. Its breakthrough Liquid Metal ZRT thermal interface material is designed to solve thermal chokepoints that are facing the next generation of AI and HPC silicon.

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.

The Role

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.

Your Responsibilities

• Act as technical owner of the manufacturing process through commissioning of our high-volume line, from installation and IQ/OQ/PQ through full production readiness.
• Design manufacturing and material flows, including robust flows for conforming and non-conforming material.
• Establish line readiness: base state, preventive maintenance plans, SOPs, and validated process windows.
• Determine equipment parameters and specification limits for critical-to-quality characteristics, and design experiments to characterize process sensitivity.
• Translate developmental materials processes into controlled manufacturing while preserving process intent.
• Implement and configure MES, SCADA, and SPC tools for real-time monitoring and traceability.
• Lead non-conformance investigations and root cause analysis, and drive corrective actions to closure.
• Anticipate and eliminate execution risk and bottlenecks during an aggressive production ramp.
• Drive continuous improvement of production and quality management systems.
• Provide tactical engineering support to the active line, and mentor engineers and technicians on process control and problem-solving.

Your Required Skills and Expertise

• Bachelor's or Master's degree in Materials Science, Chemical Engineering, Mechanical Engineering, or a related discipline (equivalent hands-on experience considered).
• Demonstrated, hands‑on experience taking a materials‑based process from development or pre‑pilot into a controlled manufacturing environment.
• Proven ability to give tactical, day‑to‑day engineering support to an active manufacturing line.
• Ability to set equipment parameters and specification limits for critical‑to‑quality characteristics.
• Experience implementing and maintaining QA/QC systems from raw material to finished product.
• Experience developing and executing equipment qualification protocols (IQ/OQ/PQ).
• Strong process control fundamentals, including SPC, control charts, and capability analysis.
• Proficiency with manufacturing software, including Ignition/SCADA, Tulip/MES, and statistical tools such as Minitab or JMP.
• Comfortable working across engineering, operations, and quality in a fast‑moving startup environment.

Your Preferred Qualifications

• Experience with specialty materials processing (e.g., liquid metals, composites, coatings, or advanced polymers).
• Lean manufacturing experience applied to reducing waste and cycle time.
• Six Sigma certification and experience with Measurement Systems Analysis (MSA).
• Prior experience in a startup or early‑stage manufacturing environment.

Summary of Benefits

• Health, Vision & Dental – Boston Materials pays 75% of Health, Vision and Dental Care coverage for employee and dependents
• Unlimited Paid Time Off
• Holidays: 14 days/year
