Senior IT Systems Engineer

SENIOR IT SYSTEMS ENGINEER

Freeform builds AI-native manufacturing systems that unify software, hardware, and physics to produce industrial-scale parts at the speed of human ideation. By treating manufacturing as a single integrated system, we unlock a new era of innovation where complex hardware is designed, built, and scaled without limits. 

As a Senior IT Systems Engineer, you will build the systems that connect our people, our factory, and our data: identity and endpoints, servers and storage, cloud and Kubernetes, the network, and the security layer over all of it. IT here is part of the technology we build, so it gets the same appetite for custom solutions to problems nobody has solved yet. Freeform is scaling rapidly across headcount, locations, and new technology coming online, so we’re looking for someone who’s excited to move fast and build the plane as we fly it. We want someone with broad skills, a “no job too big or small” mentality, and a taste for building.
