Sr. Embedded Firmware Engineer

Job Description:

Responsibilities:

• Lead firmware development for WPT Tx and Rx systems, ensuring seamless power transfer and communication.
• Develop and optimize real-time firmware in C/C++ for MCUs handling WPT, BLE communication, power negotiation, and system safety.
• Design and implement low-level drivers for I2C, SPI, UART, ADCs, GPIO, and PWM-based power control.
• Collaborate with hardware engineers to validate system performance, debug PCB-level issues, and optimize firmware for custom PCBs and sensors.
• Implement BLE-based handshake protocols between WPT Tx and Rx systems, ensuring secure data transfer and OTA firmware updates.
• Analyze schematics and PCB layouts to ensure firmware compatibility and efficiency in power conversion.
• Develop firmware validation and QA processes to test edge cases, improve reliability, and ensure compliance with UL/CE/FCC safety standards.
• Implement state-machine logic for device-specific functionalities (e.g., temperature control in kettles, motor speed regulation in blenders).
• Perform real-world debugging using oscilloscopes, logic analyzers, and hardware-in-the-loop testing.
• Provide technical documentation for firmware architecture, APIs, and system-level interactions.
• Work with OEMs/ODMs to integrate firmware into production-ready appliances.
• Ensure scalability of firmware from prototypes to mass-market consumer appliances.
