Location: Chennai

Job Type: Full-Time

Experience Level: Mid-Level

Job Summary:

We are seeking a highly skilled and motivated Embedded Systems Software Developer to join

our engineering team. The ideal candidate will have strong experience in microcontroller

(MCU)-based programming and real-time operating systems (RTOS). You will be responsible

for designing, developing, testing, and maintaining embedded firmware and software for

various applications, ensuring high performance and reliability.

Key Responsibilities:

• Design and implement embedded software for microcontroller-based systems.

• Develop real-time firmware using RTOS (e.g., FreeRTOS, ThreadX).

• Collaborate with hardware engineers for board bring-up and hardware/software

integration.

• Write low-level device drivers for peripherals such as SPI, I2C, UART, ADC, PWM,

etc.

• Develop and maintain software documentation including architecture, design, and user

manuals.

• Debug and troubleshoot software issues using tools like oscilloscopes, logic analyzers,

and JTAG/SWD.

• Participate in code reviews and ensure software development best practices.

• Contribute to system-level design, including power management and optimization

techniques.

• Support testing, validation, and deployment processes for embedded solutions.

Required Skills and Qualifications:

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or

related field.

• 4+ years of experience in embedded firmware/software development.

• Proficiency in C/C++ for embedded systems.

• Hands-on experience with microcontrollers (ARM Cortex-M, STM32.).

• Strong understanding of RTOS concepts including task scheduling, inter-process

communication, and resource management.

• Familiarity with communication protocols: I2C, SPI, UART, CAN, USB, etc.

• Experience with embedded development tools: IDEs (e.g., Keil, IAR,

STM32CubeIDE), debuggers, and emulators.

• Familiarity with version control systems (Git, SVN).

Preferred Qualifications:

• Experience with safety-critical or industrial embedded systems.

• Knowledge of bare-metal programming and interrupt handling.

• Exposure to wireless communication stacks (IoT, BLE, Zigbee, LoRa, etc.).

• Familiarity with scripting languages (Python, Bash) for automation and testing.

• Experience with CI/CD tools for embedded systems.
