Embedded Software Engineer

We are seeking a highly skilled and motivated Embedded Software Engineer to design, develop, and optimize software for battery-operated IoT devices with a strong emphasis on testing automation. The role involves developing low-level software, focusing on power efficiency, real-time performance, system reliability, and implementing robust testing frameworks. You will also contribute to Board Support Packages (BSPs), kernel-level development, and platform integration.

What you will do:

• Core Development
• Embedded Software Development: Design, write, debug, and maintain low-level software for embedded systems, including BSP and drivers.
• Power Optimization: Implement algorithms and techniques to minimize power consumption for battery-operated devices.
• Kernel and RTOS Development: Customize and optimize RTOS (e.g., FreeRTOS) or Linux kernel components for embedded platforms.
• IoT Integration: Develop secure and efficient communication protocols for IoT platforms (e.g., MQTT, BLE).
• Testing and Automation
• Test Framework Development: Create and maintain automated testing frameworks for embedded systems, including unit, integration, and regression tests.
• Support: Provide support for debugging of faulty boards.
• Prototypes Testing: Testing of prototypes for early adopting customers.
• Hardware-in-the-Loop (HIL): Implement HIL testing to validate software functionality and hardware interactions in real-time.
• Continuous Integration (CI): Integrate automated testing pipelines with CI/CD tools like Jenkins, GitLab CI, or Azure DevOps.
• Debugging and Validation: Use tools like oscilloscopes, logic analyzers, and protocol analyzers to test and debug embedded software and hardware interfaces.
• Collaboration and Documentation
• Hardware Interaction: Work closely with hardware teams to ensure seamless software-hardware integration and accurate testing scenarios.
• Documentation: Prepare and maintain technical documentation, including testing procedures, logs, and reports for software and hardware validation.

What you bring to this role:

• Programming Languages: Proficiency in C, C++, and Python; familiarity with scripting languages like Shell or Bash.
• Embedded Systems: Experience with microcontroller platforms (e.g., ARM Cortex, ESP32, STM32) and their toolchains.
• IoT Protocols: Knowledge of IoT communication protocols and secure data transmission.
• Testing Frameworks: Experience with testing tools and frameworks such as Robot Framework, Pytest, or Unity.
• Power Management: Understanding of low-power design principles, energy-efficient algorithms, and power profiling tools.
• Debugging Tools: Proficiency with debugging tools like JTAG, GDB, and serial debuggers.
• Automation Tools: Experience with CI/CD pipelines, Jenkins, GitLab CI, or similar tools.
• Version Control: Expertise with Git or similar version control systems.

Extra bonus points for the following:

• Experience with Yocto.
• Familiarity with wireless communication technologies (e.g., Wi-Fi, Bluetooth, Zigbee, LoRa).
• Knowledge of hardware protocols such as SPI, I2C, UART, and GPIO.
• Experience with secure firmware updates (OTA) and bootloader development.
• Familiarity with hardware simulation tools and mock environments for testing.
• Knowledge of Test-Driven Development (TDD) and Behavior-Driven Development (BDD) practices.
• Education: Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or a related field.

Additional Requirements

This is a fast-paced, high-impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.
