Senior Flight Software Engineer; Rust

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 Senior Flight Software Engineer who possesses expertise in the Rust programming language to take an active role in the development and delivery of embedded flight software specifically tailored for Umbra missions. In this pivotal role, you will be tasked with a range of critical responsibilities, including but not limited to the formulation and specification of software requirements, the comprehensive design of robust software architecture, and the actual writing and implementation of code.

You will take lead responsibility for the essential processes of system integration and testing, ensuring that all components function seamlessly together.

In addition to your core development responsibilities, you will also be expected to provide expert guidance and mentorship in various aspects of software design, code development, and peer code reviews. Your role will include oversight of thorough documentation practices and the meticulous integration of the flight software with flight hardware, which encompasses conducting unit testing to ensure reliability and performance. Your contributions will be vital to the success of our missions, driving innovation and excellence in software engineering within our team.

Our aim is to hire this position to work in either our Santa Barbara/Goleta, CA office, Arlington, VA office, or Reston, VA office (coming soon).
