Seeking a Senior Software Engineer with 5 to 10 years of embedded firmware RTOS experience to develop and maintain communication protocols, sensor interfaces, and system integration firmware for regulated medical devices. The ideal candidate will have robust expertise in C programming on ARM Cortex-M platforms, communication protocols (CAN, SPI, I2C, UART, USB/Ethernet, Wireless), hardware debugging, and IEC 62304-compliant development. This role offers hands-on involvement in firmware development, hardware bring-up, field issue resolution, system integration, and collaboration across engineering teams to deliver high-quality and reliable medical device software.

Key Responsibilities :
• Own the firmware architecture for all communication subsystems: Wireless stack,
CAN/SPI/I2C/UART/USB protocol stacks, and dialysate sensor interfaces.
• Design and maintain the hardware abstraction layer (HAL) strategy — ensuring firmware
portability and clean separation between hardware-specific and application-level code.
• Develop and review low-level peripheral drivers, DMA configuration,



interrupt handlers, and MCU
initialization sequences.
• Integrate Wireless communication stacks and resolve field-level communication failures through
root cause analysis and firmware fix.
• Collaborate with hardware design teams during schematic review and PCB bring-up — provide
firmware-level validation of hardware interfaces.
• Author interface control documents, protocol implementation specifications, and firmware design
documents per IEC 62304.
• Establish unit test plans and verification approaches for communication subsystems, ensuring
traceability to software requirements.
• Mentor the FW Engineers and Assoc. FW Engineers — provide technical guidance, conduct
code reviews, and support their growth.
• Partner with the Safety Architect to ensure communication firmware integrates cleanly with
safety-critical alarm and control subsystems.
• Support design transfer and manufacturing bring-u
