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 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-up — provide firmware support for factory test jigs and production calibration. • Experience with static analysis tools (Polyspace, PC-lint, Coverity, Parasoft) and unit testing frameworks for embedded C Required Qualifications • B.E./B.Tech or M.Tech in Electronics, Embedded Systems, Instrumentation, or Computer Science. • 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; solid experience with peripheral driver development 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. •Strong 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.
