WHAT THIS CAREER ACTUALLY DOES

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.
WHAT YOU PRODUCE

Concrete work products.

Space software is judged by predictable behavior, traceable testing and clear interfaces—not code volume.

A DAY IN THE WORK

A realistic workflow, not a universal schedule.

Start

Review build status, defects and mission priorities.

Build

Implement or refactor a focused capability.

Integrate

Test with simulated telemetry, hardware or adjacent services.

Review

Participate in code review and document behavior, risks and evidence.

Flight-software cycles can be highly controlled; ground-software teams may release more frequently.
