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



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