Senior Embedded Software Developer – Welding Automation Products
Department: Research & Development
Location : Chennai
Job Type: Full time (Work from Office)
Experience Level: Senior (5 to 7 years)
Key Responsibilities
Design, develop, and maintain embedded firmware for welding power sources, weld control devices, and control units used in industrial welding automation. Implement and tune real-time closed-loop control algorithms (current, voltage, and arc control) for switched-mode power conversion using PWM-based digital controllers. Develop low-level drivers and interfaces for power electronics building blocks: gate drive circuitry, power semiconductor switches (IGBT/MOSFET), current/voltage feedback sensing, and thermal protection. Work with DSP-based or ARM Cortex-M/STM32 microcontrollers to implement high-speed control loops, ADC sampling, and PWM generation for welding power converters. Collaborate with power electronics and hardware design teams on board bring-up, control-loop validation, and system-level integration of welding power sources.



Develop communication interfaces between weld controllers, power sources, and peripheral devices using CAN, RS-485, Ethernet, and other industrial protocols. Support integration with robotic and automated welding cells, ensuring reliable synchronization between weld control units and automation systems. Debug and troubleshoot firmware and control-loop issues using oscilloscopes, logic analyzers, JTAG/SWD, and power-quality measurement tools. Write and maintain design documentation, test plans, and validation reports for embedded control software in line with industrial/safety standards. Participate in code reviews, support automated testing of firmware, and mentor junior engineers on embedded and power-electronics best practices. Required Skills and Qualifications
Bachelor or Master degree in Electrical, Electronics, Power Electronics, or related engineering discipline. 5 to 7 years of experience in embedded firmware/sof
