The SIT department plays a pivotal role in ensuring the successful deployment and operation of satellites by providing support to critical areas: Flight Software, Ground Software, Vehicle Test, and Mission Operations. The department collaborates with engineering teams to develop and maintain modern software engineering solutions that lead to mission success. Additionally, it employs rigorous testing processes to validate hardware and software, minimizing risks prior to launch.

On the ground, the department supports the seamless operation of ground software systems for satellite communication, monitoring, and control, facilitating real‑time data analysis and mission management. Together, these efforts ensure that satellites are properly launched, placed into orbit, and operated efficiently, supporting a range of applications for our customers.

The ideal candidate will act as a critical interface between software developers and internal users, working across engineering teams to validate mission‑critical software from both a technical and user perspective. They will identify, document, and clearly communicate software defects, usability concerns, test results, and release risks. Success in this role requires disciplined test execution, strong attention to detail, and the ability to learn unfamiliar software and spacecraft systems quickly.

• Create and maintain test documentation, troubleshooting notes, defect records, and test reports
• Identify, reproduce, document, and track software defects, usability issues, procedural discrepancies, and unexpected system behavior
• Communicate across teams to gather information and resolve issues

Required Qualifications

• Bachelor’s degree in Aerospace Engineering, Computer Science, Software Engineering, or related STEM field
• 2+ years of experience in Software Testing, Software Systems Engineering, Software Quality Assurance, or related field
