Space
X was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today Space
X is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.
The Starshield mission is to support national security through a focus on timely and reliable information delivery. Our partners in the intelligence community and defense services need best‑in‑class technology, developed and fielded quickly and iteratively. Our goals are focused on delivering meaningful new capabilities through both new hardware development and continual software innovation.
The Starshield Software team is building software that safely and securely operates our constellation of thousands of satellites. With our focus on national security missions, we are developing novel technologies to secure our networks and data. We are looking for software engineers who are interested in learning about security applications as well as embedded system development to help us innovate.
Responsibilities- Create highly reliable software systems that control thousands of satellites in low Earth orbit.
- See your software through from start to finish: from figuring out the core needs to prototyping, developing, and testing; to on‑orbit rollout and beyond.
- Work with interdisciplinary teams to brainstorm, design, and build the next generation of satellite capabilities, from cutting‑edge sensors and inter‑satellite lasers to space‑based cloud compute.
- Work directly with end customers to deliver quality products and data to meet their needs.
- Write high quality Linux‑based C++ software for common processors and microcontrollers (e.g. ARM, Power
PC, x86, etc.). - Develop novel embedded cryptography applications for satellites and ground equipment.
- Develop highly performant networks to connect sensor data to end users.
- Build automated ground‑based software systems that integrate smart data processing with command and control of the satellites.
- Develop models and simulations for flight‑like vehicle software testing, network performance analysis, or research & development projects.
- Develop tools that allow for test execution across multiple environments: virtualized hardware, real hardware‑in‑the‑loop, and even vehicle‑in‑the‑loop testing.
- Bachelor’s degree in computer science, engineering, math, or scientific discipline; OR 2+ years of professional experience in software development in lieu of a degree.
- Development experience in C, C++, or Rust.
- Active Top Secret, Top Secret SCI, or DOE Level Q clearance.
- Solid fundamental knowledge of computer architecture, networks, debugging, and software testing.
- Ability to work effectively and creatively in a dynamic environment with changing needs and requirements.
- Ability to work independently and in a team, take initiative, and communicate effectively.
- Production experience with containerization technologies (e.g. Docker, Kubernetes).
- Experience with relational databases (Postgre
SQL, Cockroach
DB, or similar).
- Note that an active clearance may provide the opportunity for you to work on sensitive Space
X missions; if so, you will be subject to pre‑employment drug and random drug and alcohol testing. - Willing to work extended hours and weekends when needed.
