• Deep understanding of computer networking and firmware for data-intensive applications.
• Strong expertise in C programming for embedded systems, with a solid grasp of memory management and real-time operating system principles.
• Hands-on experience with connectivity modules (Wi-Fi, Bluetooth) and RTOS (FreeRTOS preferred).
• Proficiency in hardware-software interfacing, including protocols like GPIO, I2C, SPI, and JTAG.
• Proficiency with troubleshooting tools (debuggers, Wireshark) and measurement equipment (multimeters, oscilloscopes, logic analyzers).
• Demonstrated expertise in debugging and rigorous testing to quickly identify and resolve complex issues.
• Familiarity with version control, CI, and build systems.

• Experience with ESP
  32 microcontrollers.
• Working knowledge of cloud computing protocols (e.g., MQTT) and platforms like AWS (AWS CDK is a plus).
• Experience with cellular connectivity.
• Excellent communication and interpersonal skills to foster a collaborative, team-oriented environment.
