Full Description

Your Role As a Platform Test Multimedia Interoperability Validation Engineer, you will ensure seamless compatibility of USB, Display, and Charger devices across the Windows ecosystem. You will execute end‑to‑end device interoperability tests, manage a diverse hardware inventory, define test plans, and collaborate with engineering teams, OEMs, and silicon partners to improve user experience and ecosystem reliability.

In this role, you will

Validate USB, Type‑C, PD charging, DisplayPort/HDMI, Thunderbolt, hubs, docks, and charger interoperability on Windows devices.
Test scenarios like enumeration, alternate modes, display topology, PD negotiation, MST, and sleep/resume reliability across multiple hardware and Windows builds.
Manage and maintain the device inventory, track lifecycle, and source new peripherals aligned with emerging standards.
Define test matrices and collaborate with PM and Automation teams to prioritize scenarios and build automated suites.
Perform debugging across USB/PD stacks, display pipelines, drivers, and firmware using traces, logs, and dumps.
Work with OEMs, silicon vendors, and device manufacturers to reproduce, analyze, and close issues.
Stay updated with USB‑IF, VESA, HDMI, and Thunderbolt specifications and validate against new protocols.
Provide data‑driven insights to influence Windows feature design and compatibility policies.
