Loft Federal provides space infrastructure and operation as a service for whatever size mission a client needs - whether that's a constellation, a single satellite, or even flying multiple customer payloads on the same satellite.

As an Assembly Integration & Test Engineer, you'll be responsible for ensuring the satellite is built and tested before launch. This is a truly multidisciplinary role where you'll work with almost every department in Loft and no two days will ever feel the same. You may be working with the Mechanical team to determine payload arrangement, Electrical team to design harnesses, Systems team on requirements and verification, PMs on scheduling, Software team on debugging, and the Product team for testing Loft hardware.

You'll also work within the AIT team on the design and conduction of functional, performance, and environmental testing of the payloads and completed satellite. Through all of this, you'll need to be good at communication and documentation as well as have a passion for troubleshooting/debugging. This is a unique role and we're looking for a unique person to fill it!

In this role, you’ll play a hands‑on part in taking satellites from the test bench to the launch pad. You’ll work alongside the Loft team to build, integrate, test, and verify internally developed products, helping ensure each flight product is ready for successful delivery and mission operations. Your work will include electrical and mechanical integration of payloads onto satellites, as well as environmental testing at both the box and system levels—including vibration, thermal vacuum (TVAC), and electromagnetic interference (EMI) testing.

You’ll also have the opportunity to author and execute detailed test procedures, troubleshoot issues as they arise, and work collaboratively across the team to make sure our hardware performs as intended before it flies.
