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 seeking an Advanced Manufacturing Manager to lead the commissioning and ongoing operation of our high-volume manufacturing lines. This is a pivotal role at the intersection of materials development and production scale-up: you will work hand-in-hand with our equipment and process engineering teams to design and optimize production workflows, implement manufacturing execution systems, and build the operational infrastructure needed to take novel materials processes from the development environment into controlled, repeatable manufacturing. The ideal candidate is as comfortable on the shop floor debugging a newly commissioned line as they are in a planning session defining process control strategies. We value depth of experience with early-stage, materials-based processes over breadth of experience in mature, high-volume manufacturing environments. 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 Boston Materials is an EOE and at the forefront of materials innovation, the key to which is diverse teams with unique backgrounds and experiences. We are committed to employing a diverse workforce with equal employment opportunities regardless of race, color, religion, sex, national origin, age, sexual orientation, gender identity, gender expression, marital status, veteran status, or disability.   Applicants must be currently authorized to work in the US on a full-time basis.
