Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Develop and implement robust embedded C/C++ software for spacecraft avionics, sensors, and propulsion systems. Collaborate with cross-functional teams to define requirements, prototype solutions, and support post-launch mission operations.
Requires 1+ years of experience in C/C++ and Linux within an embedded environment, along with U.S. citizenship for security clearance. A bachelor's degree in Electrical Engineering, Computer Engineering, or Computer Science is preferred.
Millennium Space Systems, a part of Boeing Defense, Space and Security (BDS), is a fast, agile small satellite company focused on national security space. Our missions have direct impact to global security, like missile warning and Earth observation.
Our team is curious, bold and innovative. We take risks, innovate and explore new techniques and technologies. We influence change because we challenge the status quo. And when we watch our satellites launch, we know each one of us made it happen.
Millennium Space Systems (MSS) has an exciting opportunity for a Spacecraft Software Engineer (Level 2 or Level 3) to join our team in El Segundo, CA!
As a Spacecraft Software Engineer (Associate or Mid-Level) at Millennium Space Systems, you’ll create the software that makes our satellites function in orbit. Your code will run on our custom avionics, process signals from sensors like our star trackers, and command actuators like the propulsion system. Your software may also interface with custom payloads and perform high-level autonomy functions to ensure our spacecraft accomplish their missions. We are looking for software engineers that can lead a small team developing the for a satellite, work with other teams to determine what the software needs to do, and then write (and test!) robust embedded C/C++ to meet those requirements. And when that code is running in space, you’ll continue to support mission operations with software updates and enhancements. This position's internal job code is Software Engineer - Embedded. Our team is currently hiring for Levels 2-3.
Strong communication and organizational skills are critical to success in this position, along with the ability to build strong relationships, collaborate in a cross-functional environment, and utilize problem-solving skills to proactively identify and manage risks and opportunities.

Work collaboratively with hardware, control and system engineers to define and develop software requirements, architectures and designs suited for fault-tolerant spacecraft
Rapidly prototype novel software solutions to prove out the architecture/design concepts, quantify technical risk, and create new capabilities
Implement designs in C/C++, integrate software components, create and run unit tests, validate on Hardware-in-the-Loop and release real-time embedded solutions
Assist with system verification and qualification, assessing the outputs and documenting the results to ensure software products that meet system requirements and mission-critical standards
Be responsible for all phases of software development and problem resolution from program inception to post-launch support
Work with hardware engineers to verify hardware-hardware and hardware-software interfaces
Break down the software development needed for a program into smaller discrete tasks that can be given to others to implement and monitor their progress
Perform code reviews to ensure the software being developed is functionally correct, efficient, and meets our coding standards
This position is expected to be 100% onsite. The selected candidate will be required to work onsite at one of the listed location options.
