Senior Embedded Firmware Engineer (STM32/ARM Cortex-M, Power Control, Industrial Comms)
Hiring a Senior Embedded Firmware Engineer (6–8 years) in Mumbai for permanent role to build production-grade firmware in Embedded C/C++ on STM32/ARM Cortex-M. The work focuses on real-time microcontroller control systems including timers/PWM/ADC/DMA, ADC calibration and timer-triggered sampling, PID/control loops for fast switching power stages (MOSFET), and industrial communications (Ethernet/TCP-IP with lwIP, RS485, MODBUS RTU, SPI/I2C/UART). Strong system debugging and hardware integration skills are required, using STLink/JLink, oscilloscope and logic analyzer, with emphasis on deterministic timing and performance optimization.
