- Implement real-time control and communication systems
- Support audio-related firmware features including codec interfacing, DSP integration, and control logic
- Bring up recent hardware platforms and support board-level debugging
- Work closely with hardware teams to validate schematics, PCB layouts, and system architecture
- Develop and maintain firmware architecture, documentation, and coding standards
- Debug and resolve system-level issues across hardware and firmware boundaries
- Develop test tools and scripts to support validation and production testing
- Support integration with higher-level systems and external interfaces
- Work closely with local contract manufacturers to support firmware bring-up during builds,



assist with production test integration, and ensure smooth transition to manufacturing
- Provide ongoing support to manufacturing to troubleshoot firmware-related production issues and improve reliability and yield
- Generate technical documentation including requirements, specifications, and test reports
- Support qualification documentation and testing including environmental and EMI/EMC testing
- Undertake code reviews for merges, updates, fixes developed by other team members
- Manage source control, artifact versioning and configuration of both in-development and production firmware
- Work with technical staff from third-party vendors to develop drivers, test SDKs, and implement APIs for ICs
