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 strong 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 firmwareportability and clean separation between hardware-specific and application-level code.• Develop and review low-level peripheral drivers, DMA configuration, interrupt handlers, and MCUinitialization sequences.• Integrate Wireless communication stacks and resolve field-level communication failures throughroot cause analysis and firmware fix.• Collaborate with hardware design teams during schematic review and PCB bring-up — providefirmware-level validation of hardware interfaces.• Author interface control documents, protocol implementation specifications,



and firmware designdocuments per IEC 62304.• Establish unit test plans and verification approaches for communication subsystems, ensuringtraceability to software requirements.• Mentor the FW Engineers and Assoc. FW Engineers — provide technical guidance, conductcode reviews, and support their growth.• Partner with the Safety Architect to ensure communication firmware integrates cleanly withsafety-critical alarm and control subsystems.• Support design transfer and manufacturing bring-up — provide firmware support for factory testjigs and production calibration.• Experience with static analysis tools (Polyspace, PC-lint, Coverity, Parasoft) and unit testingframeworks for embedded CRequired Qualifications• B.E./B.Tech or M.Tech in Electronics, Embedded Systems, Instrumentation, or ComputerScience.• 8+ years of embedded firmware experience, with at least 4 years in medical devices or safety critical industries.• Expert-level C on ARM Cortex-M platforms; strong experience with peripheral driverdevelopment and DMA configuration.•Hands-on experience with multiple communication protocols at the firmware implementation level: SPI, I2C, UART, CAN, USB, and WIRELESS.•Experience designing and owning hardware abstraction layers for multi-MCU or multi-platform product families.•Robust hardware debugging skills: oscilloscopes, logic analysers, protocol analysers (CAN, USB, SPI), and JTAG/SWD.•Knowledge of IEC 62304 software lifecycle, including software architecture documentation and traceability requirements.
