They work closely with platform architects, vehicle E/E teams, Tier-1 suppliers and cloud engineers to deliver secure, reliable and scalable OTA and diagnostics services that meet engineering, quality and business targets.

Vehicle Integration & Automotive Protocols
- Integrate OTA and diagnostics services with the Telematics Control Unit (TCU) and in-vehicle ECUs over telematics interfaces.
