• Perform CAN, MOST, A2B, I2S, and Ethernet‑AVB based audio bus integration.
• Support firmware debugging for audio amplifiers, DSP modules, and infotainment ECUs.

5. Cross‑Functional Collaboration

• Collaborate with:
  • Mechanical teams for speaker enclosure design
  • Hardware teams for amplifier and PCB layouts
  • UI/UX teams for audio experience and touch response
• Provide technical feedback to suppliers and lead technical reviews.
