• Bring up new 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
