THE OPPORTUNITY

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 Senior Manufacturing Engineer to join our team at a pivotal moment–as we rapidly scale our liquid metal thermal interface material from bench‑scale to high‑volume manufacturing. You’ll be embedded on the shop floor to commission our LVM line, build the systems that keep it running reliably, and drive the continuous improvement that makes aggressive ramp targets achievable. This is a hands‑on role: you’ll own line readiness, process documentation, and quality flows end‑to‑end, and be the person who responds when production needs you.

The ideal candidate has been here before–they've personally navigated the transition from pre‑pilot to low‑volume manufacturing and know the difference between processes that look good on paper and ones that hold up under real production conditions. You bring a rigorous, data‑driven mindset, fluency with modern manufacturing execution and statistical tools, and the judgment to know when to build a system and when to just solve the problem in front of you. If you’re energized by the challenge of building something that scales, and 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

• Anticipate and eliminate manufacturing execution risk during aggressive production ramp.
• Work with Engineering and Manufacturing teams to deploy LVM line, including commissioning of manufacturing equipment.
• Implement robust flows for conforming and non‑conforming materials.
• Ensure line readiness by establishing base state, preventive maintenance plans, SOPs, and process windows.
• Drive continuous improvement of production management and quality management systems.
• Anticipate and proactively eliminate bottlenecks through streamlined processes.
• Investigate non‑conformances, lead root cause analysis, and close corrective actions.

Your Skills and Expertise

• Demonstrated experience scaling a manufacturing process from pre‑pilot to low‑volume manufacturing.
• Proven ability to provide tactical, day‑to‑day engineering support to an active manufacturing line.
• Experience implementing and maintaining QA and QC systems from raw material to finished product.
• Ability to determine equipment parameters and specification limits for critical‑to‑quality characteristics.
• Proficiency with manufacturing software including Ignition/SCADA, Tulip/MES, and statistical tools such as Minitab.
• Strong understanding of process control fundamentals, including control charts, capability analysis, and SPC.
• Experience developing and executing equipment qualification protocols (IQ/OQ/PQ).
• Familiarity with lean manufacturing principles and ability to apply them to reduce waste and cycle time.
• Six Sigma certification and experience with Measurement Systems Analysis (MSA) is a plus.
• Comfortable working across functions — engineering, operations, and quality — in a fast‑moving startup environment.
