- Support the defect management process from recognition to resolution
Qualifications:
- Bachelor’s or Master’s degree in Computer Science, Aerospace Engineering, Electrical Engineering, or STEM-related field
- 3+ years of industry experience in testing complex systems (integration of cloud tools, cloud and cloud networking, mobile applications, application UI, and operational workflows)
- Experience with designing, developing, and executing test methodologies that scale across multiple teams
- Strong software development experience with high-level language (e.g. Python, Pytest, REST API), along with version control systems (e.g Git)
- Integrated systems troubleshooting experience
Bonus Qualifications:
- Experience with Hardware in the Loop (HIL) and/or Software in the Loop (SIL)
