About the Role

We are seeking an experienced

Satellite Bus Flight Software Systems Engineer

to lead and support the system-level definition, architecture, integration, verification, and operational readiness of flight software for current and next-generation spacecraft platforms.

This is a

systems engineering and technical leadership

role at the intersection of spacecraft architecture, platform subsystems, embedded flight software, avionics, mission operations, and verification. You will ensure that spacecraft bus flight software meets platform and payload functional, performance, autonomy, safety, reliability, and operational requirements throughout the full spacecraft lifecycle—from early architecture and detailed design through integration, launch preparation, commissioning, and on-orbit operations.

Key Responsibilities

• Translate functional, performance, safety, and security requirements into flight software requirements and architecture.
• Allocate requirements to software modules and execution threads while maintaining bidirectional requirements traceability.
