Senior Software Engineer (SatOS Team)

We are seeking an experienced Software Engineer 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 Python/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
• Work with our customers to translate their requirements into effective software solutions

Key Skills:

• 5+ years experience in professional software development
• Proven experience in production-grade software development using at least one compiled language
• 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
• Good customer relations 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
• Proficiency in Python and Rust
• Understanding of cybersecurity principles systems
• 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:

• Python, Rust, Bash
• Ubuntu (development environment)
• gRPC (inter-process communications)

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 required for this role. If needed, Spire will arrange the necessary licenses—this is not something candidates need to have before applying.

Global Perks:

• Name Your Satellite Program (NYSP)
• Launch Attendance
• Generous Time Off Policy
• Education Assistance Program
• Employee Assistance Program (EAP)
• Employee Stock Purchase Program (ESPP)
• Family Leave
• Fitness Reimbursement
• Employee Referral Program
• Healthy snacks
