Are you the one? As a Junior Embedded Developer, you will be responsible for developing embedded firmware for microcontroller-based systems and designing graphical user interfaces (GUIs) for embedded platforms. Your work will range from writing efficient Embedded C code to developing intuitive and responsive UIs that interact seamlessly with the hardware. You will collaborate closely with hardware engineers and other developers to create integrated embedded solutions for our products. Join our innovative team as we craft next-generation biometric authentication devices. You will play a crucial role in co-developing the embedded software that powers our breakthrough palm vein recognition technology, from prototyping through to mass production, ensuring it meets the highest standards of quality, security, and compliance.

Responsibilities:

• Firmware Development for Embedded Systems:

  • Write efficient Embedded C code to control microcontroller hardware, including sensors, displays, and communication interfaces (I2C, SPI, UART).
    
  • Optimize code for performance and memory constraints typical in embedded environments.
    
  • Debug and troubleshoot embedded systems using tools like JTAG, oscilloscopes, and serial debuggers.
    

• GUI Development for Embedded Platforms:

  • Design and implement real-time graphical user interfaces (GUIs) for embedded systems with displays such as LCD, OLED, or touchscreen.
    
  • Use embedded GUI frameworks like LVGL, TouchGFX, or emWin to create visually appealing, responsive interfaces optimized for resource-constrained devices.
    
  • Ensure that GUIs are intuitive, performant, and power-efficient.
    

• System Integration:

  • Collaborate with hardware engineers to define and implement hardware communication protocols (e.g., SPI, I2C) between embedded systems and external devices.
    
  • Integrate embedded systems with cloud services or remote devices, where applicable (e.g., via MQTT, HTTP).
    

• Testing and Debugging:

  • Write and execute unit and integration tests to ensure firmware and UI functionality.
    
  • Troubleshoot hardware/software issues using debugging tools (e.g., logic analyzers, oscilloscopes).
    
  • Profile embedded systems to optimize performance, memory usage, and power consumption.
    

• Documentation and Collaboration:

  • Document design, code, and testing processes to ensure clear communication within the team.
    
  • Participate in code reviews and contribute to best practices for embedded development.
    
  • Work closely with cross-functional teams to meet project goals and timelines.
