About the job

Requirements
  • Associate Degree or technical certification in Chemistry, Materials Science, Engineering, or a related field; or equivalent experience.
  • 1+ years of hands-on experience working in an R&D, QC, or manufacturing laboratory setting, preferably with advanced materials, polymers, or composites.
  • Ability to work independently and collaboratively within a fast-paced R&D/manufacturing team.
  • Proven experience with standard laboratory practices, safety protocols, and chemical handling and familiarity with common material characterization techniques (e.g., mechanical testing, microscopy).
  • Proficiency in Microsoft Office Suite (Excel, Word) for data entry and report generation.
  • Excellent attention to detail, organization, and time management, and a commitment to accurate and high-quality work.
Responsibilities
  • Operate, maintain, and execute varied testing on raw materials, in-process samples using specialized lab equipment, including but not limited to Thermal Analysis Equipment, Mechanical Testers (e.g., Universal Testing Machine for tensile, compression, and shear), Electrical Testing Equipment, Calendering Tools, and Die cutting.
  • Following detailed SOPs, prepare samples, including composite layup, cutting, polishing, and mounting.
  • Assist scientists and engineers with experimental setups, material mixing, formulation preparation, and small-scale batch processing related to our Z-axis Fiber™ composites; troubleshoot process deviations and material issues under the direction of engineers.
  • Monitor and record critical processing parameters (e.g., temperature, pressure, time) during pilot and production runs and promptly report out-of-spec or non-conforming results to the appropriate personnel.
  • Accurately record, manage, and analyze experimental and quality control data using laboratory notebooks, Laboratory Information Management Systems (LIMS), and spreadsheets.
  • Ensure all testing and calibration logs are maintained in compliance with internal Quality Management System (QMS) standards.
  • Maintain a clean, organized, and safe laboratory environment in accordance with Environmental Health & Safety (EH&S) policies.
Desired Qualifications
  • Bachelor’s degree in Materials Science, Chemical Engineering, or a related discipline.
  • Direct experience with carbon fiber composites, prepregs, or thermal interface materials.
  • Experience operating and maintaining lab equipment or working in High Volume Manufacturing (HVM) environments.
  • Familiarity with QMS like ISO 9001.

About the company

Boston Materials develops and manufactures advanced energy-transfer composites for high-performance electronics, aerospace, and electrified mobility. Its Liquid Metal ZRT® uses vertically oriented carbon fibers embedded in a liquid metal matrix to create a drop-in thermal interface that conducts heat efficiently between components, and is designed for seamless integration into automated assembly. The company differentiates itself by combining Z-axis carbon fiber reinforcement with a liquid metal matrix and scaling via roll-to-roll production using reclaimed carbon fiber, enabling multiple applications from a single platform. Its goal is to scale production to meet industrial demand across semiconductor, aerospace, and electrified-vehicle markets while expanding sustainability through recycled carbon fiber use.

Simplify's Take

What believers are saying

  • December 2025 Mitsubishi collaboration targets HPC and AI data-center demand.
  • LMZ1100 already delivered over 10°C cooling gains on kilowatt-scale GPUs and ASICs.
  • The company launched 60-inch-wide industrial-scale Z-axis fiber production in 2025.

What critics are saying

  • Boston Materials remains capital-constrained after $13.5 million in 2024 funding.
  • Second-generation ZRT commercialization depends on Mitsubishi integration labs in Asia.
  • A single thermal-product failure or customer redesign could crush adoption by 2027.

What makes Boston Materials unique

  • Liquid Metal ZRT pairs Z-axis carbon fiber with liquid metal for chip cooling.
  • Boston Materials claims drop-in pick-and-place integration for automated semiconductor assembly lines.
  • Mitsubishi Chemical backed second-generation ZRT development in December 2025.
