About the company
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
Mission Solutions – The Platforms
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.
If you want to work on cutting-edge space technology that’s redefining what’s possible in space platforms, you belong here at Umbra.
About the Job
As Umbra’s Cryptographic Systems Engineer, you will own the architecture, integration, and lifecycle management of Type 1 cryptographic capabilities across our space and ground systems. You will lead the development of secure communications architectures from concept development and trade studies through implementation, integration, verification, NSA certification and accreditation, launch, and on-orbit operations. Working closely with mission systems, spacecraft, ground software, government customers, and the National Security Agency, you will define the COMSEC architecture that protects command and telemetry links, mission data, and cross-domain interfaces for national security missions. This role is responsible for ensuring Umbra’s secure communications solutions meet the highest standards for performance, resiliency, and compliance while supporting rapid development, production, and deployment of advanced space systems. As the technical authority for cryptographic integration, you will establish the engineering standards, certification strategy, and secure communications framework that future Umbra programs build upon.
This position is based on-site in either our Arlington, VA office or Reston, VA office.
Key Responsibilities
•
Own the end-to-end architecture and design of Type-1 cryptographic integrations across the spacecraft, payload, and ground segment.
