Summary
🤩
Rockstar🎓
Top SchoolAmy Lei is a Lead System Test Engineer with over 20 years in software development, system integration, and testing, currently shaping satellite and air-traffic surveillance solutions at L3Harris. She designs and validates complex distributed systems—most recently a satellite-based DTCS using the Iridium constellation and space-based ADS-B integrations—while building test frameworks that simulate 100% real-time air traffic to accelerate validation. Skilled in MATLAB, Python, automation tools and deep protocol/database troubleshooting, she leads cross-functional test teams through feature, integration and customer-witness testing and owns verification traceability. Amy also contributes to notable open-source Python projects like Jinja2 and Click, improving template behavior, CLI parsing edge cases, and test coverage—underlining a strong backend and test-automation pedigree. Comfortable under tight schedules, she pairs rigorous engineering with clear customer-facing reporting and readiness reviews. Unusually for a senior test lead, she blends low-level protocol work with hands-on OSS back-end contributions that improve robustness across ecosystems.
