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.
About the Team
Space Systems – The Components
Space Systems is where Umbra turns hardware and software designs into on-orbit realities; developing, implementing and iterating mission-ready core technology, while simultaneously advancing the next generation of our own satellite constellation. Space Systems is vertically integrated across the satellite architecture, thus the team designs, builds, and tests an array of critical components and subsystems, including power systems, communications, control systems, deployment hardware, avionics, and payloads, as well as the flight software, firmware and digital design solutions to support the entire hardware stack. Our focus is on first principles engineering, and our mandate is simple: it has to work when it counts. Every bolt, board, and binary is proven on our own SAR constellation, ensuring flight-proven reliability where failure is not an option.
If you want to work on cutting edge space technology while maintaining the highest standard for innovation and mission ready performance, you belong here at Umbra.
About the Job
We are on the lookout for a highly skilled and experienced Senior GNC Engineer (Guidance, Navigation, and Control), who will be instrumental in the development and delivery of next-generation spacecraft capabilities tailored for Umbra missions. This role sits at the intersection of GNC theory and software implementation, focusing on enabling advanced onboard processing, new mission features, integrated testing, and expanded operational capabilities while maintaining support for legacy systems. Your expertise will be crucial in shaping the architecture, driving algorithm development, and ensuring thorough system integration. Additionally, you will be responsible for producing comprehensive documentation and conducting rigorous testing protocols, all of which are vital to guarantee the successful deployment of mission-critical software that meets the high standards required for our ambitious missions.
Our aim is to hire this position to work in either our Santa Barbara/Goleta, CA office or Arlington, VA office.
