Embedded Software Engineer

Embedded Software Engineer

Experience- 3 to 4 years

Position Overview

We are seeking a motivated Embedded Software Engineer with 3 to 4 years of hands-on experience in firmware and system-level development. The ideal candidate will have a strong background in embedded C/C++ programming, RTOS-based design, and practical experience with ESP-IDF, FreeRTOS, STM32, Raspberry Pi, and peripheral interfacing. The role requires working closely with hardware, firmware, and cross-functional teams to design, develop, and optimize embedded solutions for real-world applications. 

Key Responsibilities

● Design, develop, and maintain embedded software for microcontrollers (STM32, ESP32, Raspberry Pi).

● Develop and integrate firmware modules using ESP-IDF and STM32CubeIDE.

● Implement multitasking applications with FreeRTOS, including task scheduling, synchronization, and inter-task communication.

● Work with hardware engineers to debug, validate, and optimize system performance.

● Develop drivers and applications for UART, I2C, SPI, ADC, PWM generation, GPIO control, and timers.

● Conduct unit testing, integration testing, and debugging using tools such as logic analyzers, oscilloscopes, and debuggers.

● Optimize code for real-time performance, memory efficiency, and low power consumption.

● Contribute to design reviews, documentation, and coding standards for embedded systems.

● Support prototyping, bring-up, and deployment of embedded solutions. 

Required Skills & Experience

● 3–4 years of professional experience in embedded systems/firmware development.

● Strong proficiency in C/C++ programming for microcontrollers.

● Solid understanding of RTOS concepts (tasks, queues, semaphores, timers) with hands-on FreeRTOS experience.

● Experience with ESP-IDF development framework for ESP32-based solutions.

● Experience with STM32 microcontrollers using STM32Cube HAL/LL drivers and STM32CubeIDE.

● Hands-on expertise in peripheral interfacing: UART, I2C, SPI, ADC, PWM, GPIO, and timers.

● Exposure to Raspberry Pi (Linux-based applications, GPIO, peripheral drivers).

● Strong debugging skills using JTAG/SWD debuggers, oscilloscopes, and logic analyzers.

● Familiarity with Git or other version control systems.

● Good understanding of electronics fundamentals (digital/analog circuits, schematics, datasheets). 

● Bachelor’s degree in Electronics, Electrical, Computer Science, or related field.

● Master’s degree is a plus. 

Good to Have

● Experience with wireless communication protocols (BLE, Wi-Fi, MQTT).

● Knowledge of IoT protocols and cloud integration.

● Experience in bootloaders, OTA updates, and secure firmware.

● Familiarity with Python for scripting and test automation.

● Knowledge of Linux device drivers and cross-compilation toolchains.

Soft Skills

● Strong analytical and problem-solving abilities.

● Ability to work independently as well as in a cross-functional team.

● Effective communication and documentation skills.

● Self-motivated, detail-oriented, and eager to learn new technologies.
