Freeform is deploying software-defined, autonomous metal 3D printing factories around the world, bringing the scalability of software to physical production. Our proprietary technology stack leverages advanced sensing, real-time controls, and data-driven learning to produce digitally-verified, flawless parts at unprecedented speed and cost. Our mission is to make the transformative power of 3D printing available to all industries at scale and unlock the future of innovation.

As a Senior Materials Engineer at Freeform, you will have the unique opportunity to establish the company’s M&P infrastructure, strategy, and best practices for our advanced metal 3D printing technology. We are looking for someone with solid fundamentals in materials engineering, an understanding of metals, and a keen interest in working on the cutting edge of additive manufacturing development. In this role, you will own materials engineering efforts from cradle to grave, including hands-on sample testing, analysis of findings, and strategic process improvements. If you want to make an impact at a rapidly growing company that’s revolutionizing metal additive manufacturing, we’d love to hear from you!

3D printing experience is not required to be successful here - rather we look for smart, motivated, collaborative engineers who love solving hard problems and creating amazing technology!
