Infrastructure Engineer

Hadrian is building autonomous factories to reindustrialize America. By combining AI, advanced software, robotics, and full-stack manufacturing, we help aerospace and defense companies build rockets, satellites, aircraft, ships, and other mission-critical systems up to 10x faster and at significantly lower cost.

In this role you'll define the technical direction for the infrastructure platform powering automated manufacturing across multiple factory sites. You'll shape the architecture spanning cloud, edge, and factory-floor systems, setting the standards, patterns, and engineering culture that the entire organization builds on. You'll move fluidly between strategy and implementation: one day driving a multi-cluster Kubernetes architecture decision, the next pairing on a Terraform module that makes it real. This role demands someone who has simplified complex systems at org scale, built platforms that engineers love to use, and grown the people around them. Not just shipped impressive infrastructure, but made everyone else's infrastructure better too.
