Senior Spacecraft Mechanical Engineer

Senior 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.

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.

We are seeking a skilled and motivated professional to join our multidisciplinary engineering team as a Senior Spacecraft Mechanical Engineer, where 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 Santa Barbara, CA office.

Key Responsibilities

• Design, analyze, build, and test spacecraft hardware and mechanisms, including:
• Collaborating with cross-functional teams to define and refine requirements.
• Developing initial design concepts and physical prototypes.
• Working closely with the Chief Engineer and Systems Architects to optimize designs for performance and manufacturability.
• Creating detailed design documentation, including drawings, design guides, and Interface Control Documents (ICDs).
• Documenting analysis and test results.
• Developing and executing work instructions, test plans, and test reports.
• Partnering with technicians and manufacturing engineers to troubleshoot and resolve hardware issues.
