Role Summary

Responsible for developing, debugging, and maintaining firmware for industrial devices with a focus on low-level driver development, communication protocol stacks, and hardware-software integration. The role involves close collaboration with hardware teams, and system integrators to ensure reliable device operation in industrial environments.

Key Responsibilities

• Develop and maintain device drivers for microcontroller-based industrial hardware, including peripheral drivers (UART, SPI, I2C, ADC, GPIO, timers, DMA) and external device interfaces.
• Implement and integrate industrial communication protocol stacks -Modbus RTU/TCP, industrial Ethernet protocols as required by the product line.
• Design and implement real-time control logic within firmware, including state machines, interrupt-driven architectures
• Bring up new hardware - perform board bring-up, write and validate BSPs, and collaborate with hardware engineers on schematic reviews and signal integrity debugging.
• Write, review, and maintain firmware for safety-critical and reliability-critical applications in industrial settings (injectors, sensors, actuators, or similar devices).
• Debug firmware issues using oscilloscopes, logic analyzers, JTAG/SWD debuggers, and protocol analyzers. Perform root cause analysis on field failures and intermittent issues.
• Maintain firmware build systems, version control practices, and release processes. Write technical documentation including interface specifications, driver API docs, and integration guides.
• Support integration with higher-level systems - provide technical inputs to PLC/SCADA teams on device behavior, communication object dictionaries, register maps, and timing constraints.

Required Skillset

• Strong C programming (bare-metal and RTOS-based - FreeRTOS, Zephyr, or equivalent)
• Hands-on experience with ARM Cortex-M microcontrollers (STM32, NXP, TI, or similar)
• Solid understanding of MCU peripherals - UART, SPI, I2C, CAN, ADC, DMA, timers, watchdog
• Experience with industrial communication protocol (i.e. Modbus)
• Experience with wireless stack Zigbee, BLE
• Able to design, review and understand the wireless device specs
• Ability to read schematics and datasheets, and work with hardware engineers on debugging
• Proficiency with debugging tools - JTAG/SWD, logic analyzers, oscilloscopes, CAN/serial protocol analyzers
• Understanding of real-time constraints, interrupt priorities, and timing-critical firmware design
• Familiarity with embedded build toolchains (GCC ARM, Keil, IAR), Make/CMake, and Git-based workflows
• Experience writing clean, modular, well-documented embedded C with proper abstractions (HAL layers, driver APIs)

Good to Have

• Experience with power electronics firmware (AC-DC sensing, relay/contactor control, motor drive interfaces)
• Familiarity with CI/CD for embedded (automated builds, static analysis - PC-lint, MISRA checks)
