Spacecraft Mechanical Engineer

Umbra is an American space technology company delivering advanced systems, from sensors to spacecraft, that empower customers worldwide with unmatched access to critical information from space. Our mission is simple and ambitious: redefine space— for people, systems, and missions in every domain. Umbra’s ecosystem operates through three business units:
Remote Sensing (the data), Space Systems (the components), and Mission Solutions (the platforms). Together, our teams develop capabilities that deliver persistent access, resilient performance, and mission-ready solutions, advancing U.S. space leadership while keeping the world safe and informed.

Mission Solutions builds on Umbra’s expertise in remote sensing and spacecraft operations to engineer platforms purpose-built for U.S. and allied defense and intelligence missions. Whether it’s a custom payload, a full‑stack spacecraft, or the infrastructure behind an entire constellation, our team delivers secure, resilient systems tailored to exacting requirements and built on timelines that match the urgency of the mission.

We are seeking a skilled and motivated professional to join our multidisciplinary engineering team as Spacecraft Mechanical Engineer to support Umbra’s Mission Solutions business unit. This is a unique role, providing you with both ownership and oversight of new and innovative spacecraft products to support a variety of Mission Solutions customer mission sets. Our ideal candidate will effortlessly blend traditional spacecraft design principles with the nimbleness of commercial methodologies to achieve innovative capabilities and outstanding results.

You will play a key role in developing next‑generation space systems and mechanisms. The ideal candidate is passionate about designing, prototyping, building, and testing hardware using first principles engineering, and thrives in a fast‑paced, collaborative environment.

This position is based on-site in our Reston, VA office.
