Boston Materials produces a new class of materials that are conductive and durable like metal, yet light like plastic. The underlying technology revolves around vertically aligning carbon fibers to create materials with highly efficient energy dissipation properties. We use these highly differentiated materials to solve critical challenges relating to thermal management, vehicle weight reduction, and improving resource efficiency across Semiconductor, Electrified Vehicles, and Aerospace industries. Backed by proven manufacturing processes and validation in performance-critical applications across high-growth sectors, industry leaders turn to Boston Materials to go beyond today’s known limitations.
OPPORTUNITY KNOCKS
Not often in one’s career do we get the chance to—
Get close to the mission. Getting a real sense of what the business does and how our work directly affects the outcome. Where everyone is involved with the company’s success. No layers, no silos, no bureaucracy. Just the opportunity to make the greatest impact with the most responsibility.
Innovate faster. Adapting to changes in the market at record speed. No multi-layer signoffs. Fewer executives and shareholders to gain approval from. Instead, the latitude needed to get a new idea, product, or process off the ground quickly. Where we can experiment and test new ideas— and are encouraged to do so. We create solutions to problems that our audiences truly care about and understand customers won’t wait for us to figure them out.
Branch beyond our role. We’re not defined by past experiences or confined by our current job description. Every day offers opportunities to have influence and be challenged with new projects and tasks. Working shoulder-to-shoulder with some of the top talent in the industry, we’re able to showcase our talents, expand our knowledge, develop new skills, and take ownership and act. All while contributing to the overall success of the organization.
Create critical resources. The transition to a decarbonized economy is already underway and advanced computing is everywhere. Armed with coveted technologies and solutions, we unlock the way to accelerate electrification, increase compute efficiency, and harness cleaner energy— changing entire industries and our planet.
