Sr. Embedded Firmware Developer

ROLE OVERVIEW:

We are looking for a Senior Embedded Firmware Engineer with 68 years of hands-on experience in embedded product development, particularly in microcontroller-based control systems, power electronics control, data acquisition, and industrial communication.

The candidate should have strong experience in Embedded C, STM32/ARM Cortex-M microcontrollers, timers, ADC calibration, TCP/IP, RS485, MODBUS, SPI, and IC.

KEY RESPONSIBILITIES:

Design, develop, and maintain production-grade embedded firmware using Embedded C/C++

Develop firmware for ARM Cortex-M based microcontrollers, preferably STM32.

Configure and develop drivers for Timers, PWM, ADC, DMA, SPI, IC, UART

Develop firmware for power control and MOSFET switching applications.

Implement PWM-based control of MOSFETs and power stages.

Implement ADC calibration, timer-based triggering for ADC sampling and control loops.

Implement and tune PID/control algorithms where required especially for fast switching applications.

Develop and debug TCP/IP and Ethernet communication.

Implement RS485 and MODBUS RTU communication.

Develop communication protocols and register maps for industrial/control applications.

Perform hardwarefirmware integration and system-level debugging (with STLink or JLink).

Analyse timing, ADC sampling, PWM, switching, and communication issues using digital oscilloscope.

Optimize firmware for real-time performance, CPU utilization, memory, and deterministic timing.

Participate in firmware architecture, design reviews, testing, and documentation.

Experience in handling digital oscilloscope, logic analyzer.

Perform root-cause analysis of hardware/firmware issues and provide corrective solutions.

TECHNICAL SKILLS:

Must have:

Ethernet/lwIP, DMA, PID/control algorithm development

ADC calibration and timer-based triggering for sampling and control loops.

Experience with microcontrollers, microprocessor and communication protocols (e.g., SPI, I2C, UART, Ethernet, Modbus, USB).use analysis of hardware/firmware issues and provide corrective solutions.

Good to have:

Experience with FPGA (VHDL and Verilog), RTOS/FreeRTOS, and Power electronics

Experience with LVDS and CAN

Experience with MOSFET switching applications
