Principal Manufacturing Engineer

Boston Materials•Billerica, MA

1d•$150,000 - $200,000

About The Position

Boston Materials is seeking a Principal Manufacturing Engineer to serve as the technical lead for commissioning its high-volume manufacturing line as the company scales its Liquid Metal ZRT thermal interface material from bench-scale to high-volume production. This is a senior, hands-on technical role embedded on the shop floor, with ownership of the manufacturing process from commissioning through production readiness. The engineer will define process windows and controls and build the production and quality systems needed to meet ramp targets, partnering with equipment and process engineering teams to make novel materials processes controlled and repeatable. The role sets the technical standard for manufacturing while also providing direct support to production. The ideal candidate has personally helped move a novel materials process from pre-pilot to production, brings a rigorous, data-driven approach and is comfortable balancing system-building with immediate problem-solving. The position offers the opportunity to contribute to thermal management solutions for next-generation AI infrastructure.

Requirements

Bachelor's or Master's degree in Materials Science, Chemical Engineering, Mechanical Engineering or a related discipline; equivalent hands-on experience is considered.
Hands-on experience taking a materials-based process from development or pre-pilot into a controlled manufacturing environment.
Ability to provide 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 and Tulip/MES, and statistical tools such as Minitab or JMP.
Comfort working across engineering, operations and quality in a fast-moving startup environment.

Nice To Haves

Experience with specialty materials processing, such as 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.

Responsibilities

Act as technical owner of the manufacturing process through commissioning of the high-volume line, from installation and IQ/OQ/PQ through full production readiness.
Design manufacturing and material flows, including robust handling flows for conforming and non-conforming material.
Establish line readiness, including 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 risks 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.
