Senior Firmware Engineer

Job Description: Firmware / Embedded Software Engineer

Role Overview

We are looking for a skilled Embedded Software Engineer to design, develop, and maintain firmware for microcontroller-based embedded systems. The role involves low-level programming in Embedded C, working with RTOS, and implementing communication protocols while interfacing with various hardware peripherals.

Key Responsibilities

• Design, develop, and debug embedded firmware using Embedded C
• Develop and maintain applications on RTOS-based systems (FreeRTOS, ThreadX, Zephyr, etc.)
• Implement and maintain communication protocols such as UART, SPI, I2C, CAN, USB, Ethernet, MQTT, or Modbus
• Work with microcontrollers (ARM Cortex-M, STM32, NXP, TI, Microchip, etc.)
• Configure and interface peripherals: GPIO, Timers, ADC, DAC, PWM, Watchdog, DMA
• Perform board bring-up and low-level driver development
• Debug using JTAG/SWD, logic analyzers, oscilloscopes
• Optimize firmware for performance, memory, and power consumption
• Collaborate with hardware, QA, and system teams
• Follow coding standards, documentation, and version control (Git)

Required Skills & Qualifications

• Strong proficiency in Embedded C
• Hands-on experience with RTOS concepts (tasks, scheduling, semaphores, mutexes, queues, interrupts)
• Experience with microcontroller architectures
• Solid understanding of embedded peripherals and registers
• Experience implementing communication protocols
• Familiarity with bare-metal and RTOS-based firmware
• Debugging skills using hardware and software tools
• Understanding of memory management, linker scripts, and boot process

Good to Have

• C++ for embedded systems
• Embedded Linux exposure
• Bootloaders and firmware update mechanisms (OTA)
• Low-power design techniques
• Safety or automotive standards (MISRA, ISO 26262)
• Experience with CI/CD for embedded systems

Education

• Bachelor's degree in Electronics, Computer Engineering, or related field

Experience Level (Customize)

• Senior: 6- 10 years
