Job DescriptionSeeking 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 manu
