Senior Site Reliability Engineer

Senior Site Reliability 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.

If you want to work on cutting-edge space technology that's redefining what's possible in remote sensing, you belong here at Umbra.

We are seeking an experienced Senior Site Reliability Engineer to help design, build, operate, and scale the mission- and business-critical infrastructure that powers Umbra's systems. In this role, you will leverage a deep understanding of modern infrastructure, distributed systems, and the broader technology stack to drive technical excellence, make thoughtful architectural decisions, and balance long-term scalability with operational reliability.

You'll partner closely with engineering teams to improve processes, champion best practices, evaluate emerging technologies, and implement solutions that enhance the performance, resilience, and efficiency of our platforms. The ideal candidate is a collaborative technical leader who communicates effectively across technical and non-technical teams and drives meaningful improvements that have a lasting impact across the organization.

This position is based on-site in either our Arlington, VA office, Reston, VA office or Santa Barbara/Goleta, CA office.
