Flight Software Engineer III

About the role

The role is part of the In-Space Systems business unit, which is focused on addressing two of the most compelling challenges in spaceflight today: space infrastructure and increasing mobility on-orbit. As a Flight Software Engineer III, you will play a critical role in designing, developing, testing, and deploying embedded flight software for spacecraft systems supporting a broad mission portfolio — from commercial and civil space to national security.

Responsibilities

• Design, develop, integrate, and test real-time embedded flight software in C/C++ for spacecraft avionics
• Lead translation of system and software requirements into robust, flight-quality code in partnership with systems, avionics, GN&C, and test engineers
• Drive work across all phases of the software development lifecycle — from requirements and architecture through implementation, code review, verification, and deployment
• Develop and execute software verification and validation plans, including unit, integration, and automated regression tests
• Debug and resolve software and hardware/software integration issues in Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) environments
• Lead design, code, and peer reviews
• Investigate software anomalies and lead root cause analysis
• Ensure software deliverables comply with applicable safety, quality, and mission assurance standards
