Job description

Senior Manufacturing Engineer | Boston, MA | $120 - 180k

We are partnering with a company that produces advanced materials with enhanced energy transfer properties using its patented Z-axis Carbon Fiber technology. The company's products address critical performance bottlenecks across thermal, electrical, and structural applications. Its breakthrough Liquid Metal ZRT thermal interface material is engineered to overcome thermal limitations facing the next generation of AI and HPC silicon

.
The Ro

le
We are seeking a Senior Manufacturing Engineer to join our team at a pivotal stage as we rapidly scale our liquid metal thermal interface material from bench-scale development to high-volume manufacturing. In this hands‑on role, you'll be embedded on the production floor, leading the commissioning of our LVM line, building the systems that ensure reliable operation, and driving continuous improvement to support an ambitious production ra

mp.
You'll own line readiness, process documentation, and quality workflows from end to end, serving as a key engineering resource for day‑to‑day manufacturing operati

ons.The ideal candidate has successfully navigated the transition from pre‑pilot to low‑volume manufacturing and understands the difference between processes that work in theory and those that perform consistently in production. You bring a disciplined, data‑driven approach, experience with modern manufacturing execution systems and statistical tools, and the judgment to know when to develop scalable systems and when to solve immediate production challenges. If you're motivated by building manufacturing capability from the ground up and want your work to directly impact one of the most critical thermal management challenges in next‑generation AI infrastructure, we'd love to hear from

you.
