Senior Software Engineer (Rust)

We are seeking an experienced Software Engineer (Rust) to join our Sat OS team (which develops the high-level operating system for the spacecraft ) . The successful candidate will play a crucial role in developing software for our satellite systems, contributing to the expansion and enhancement of our space-based payload execution and data collection capabilities. Ideal candidates will embrace the commercialisation of nanosatellite systems and adapt to low-cost, fast-paced systems design, development, and implementation methodologies that set Spire apart from our competition. In this fast-paced environment, the design to launch cycle is measured in weeks and months, not years! What You’ll Do as a Sat OS Software Engineer: • Develop services in Rust that interface with hardware integration layers using modern protocols • Implement communication interfaces between higher-level processes , including ground to space commanding • Migrate legacy Python systems to a new Rust-based, distributed architecture • Contribute to the design and implementation of fault-tolerant systems to meet the demands of new customer missions • Collaborate closely with the Platform Engineering team to ensure optimal software-hardware integration • Create and maintain comprehensive documentation for APIs and system architectures • Contribute to the continuous improvement of our development processes and tools • Perform ground-based testing and in-orbit verification of new software services • Implement observability solutions for satellite-side services Key Skills: • 7+ years' experience in professional software development • Proven experience in production-grade software development using Rust • Proficiency in Python or equivalent high-level language • Knowledge of Linux-based development • Experience with inter-process communication protocols (such as gRPC ) • Ability to communicate effectively with embedded software engineers • Excellent documentation skills Preferred Skills: • Familiarity with safety-critical software systems in any industry • Knowledge of version control systems, particularly Git and GitHub • Familiarity with CI/CD pipelines • Experience with project management tools • Proficiency in scripting languages like Bash • Understanding of cybersecurity principles s ystems • Knowledge of telemetry and command systems • Experience in implementing Fault Detection, Isolation, and Recovery (FDIR) systems for high-level or embedded applications Tools and Technologies: • Rust, Python, Bash • Ubuntu (development environment) • gRPC (inter-process communications) • Version control using Git We value adaptability and a willingness to learn new tools and technologies as needed for the role. Spire operates a hybrid work model, and this position will require you to work a minimum of three days per week in the office. Access to US export-controlled software and/or technology may be for this role. If needed, Spire will arrange the necessary licenses—this is not something candidates need to have before applying. #LI-MI1
