Apply CCA‑level design knowledge (schematics, layouts, component behavior, and manufacturing interfaces) to identify defect root causes related to soldering, component sensitivity, layout robustness, thermal effects, and test access. Operating in a complex, regulated avionics manufacturing environment, the role partners closely with Manufacturing, Test, and Operations, and works in tight collaboration with Quality, who owns first‑mile and last‑mile quality including supplier and customer‑facing issues.
