Spacecraft & Ground Software
Develop, test and maintain software used aboard spacecraft or in ground systems.
Work behind the title.
Flight software
- Implement onboard control, data handling and fault-management logic.
- Work within timing, memory and reliability constraints.
- Support reviews, qualification and release baselines.
Ground software
- Build command, telemetry and mission-planning applications.
- Develop interfaces, APIs and operator workflows.
- Automate repeatable mission tasks.
Integration & test
- Create unit, integration and hardware-in-the-loop tests.
- Investigate defects across software and hardware boundaries.
- Maintain traceability and configuration control.
Software assurance
- Review code and requirements.
- Document releases, risks and verification evidence.
- Apply secure development practices where required.
Concrete work products.
Space software is judged by predictable behavior, traceable testing and clear interfaces—not code volume.
A realistic workflow, not a universal schedule.
Review build status, defects and mission priorities.
Implement or refactor a focused capability.
Test with simulated telemetry, hardware or adjacent services.
Participate in code review and document behavior, risks and evidence.
Flight-software cycles can be highly controlled; ground-software teams may release more frequently.
