• Strong experience with microcontrollers (ESP32, STM32, Atmel, etc.) and IoT development boards.
• Solid understanding of serial protocols (SPI, I2C, UART) and sensor interfacing.
• Practical experience in using tools like Keil, PlatformIO, STM32CubeIDE, or Arduino IDE.
• Familiarity with wireless communication modules and cloud connectivity (AWS IoT, Azure IoT, Blynk, etc.).
• Experience in using hardware tools like oscilloscopes, logic analyzers, and multimeters.
• Working knowledge of PCB debugging and hardware bring-up.
• Exposure to Git or similar version control systems.

Preferred Qualifications

• Bachelor's or Master's degree in Electronics, Electrical, Instrumentation, Mechatronics, or a related field.
• Experience with IoT security best practices.
• Exposure to Linux-based embedded systems (Raspberry Pi, BeagleBone).
• Hands-on with OTA firmware update mechanisms and remote monitoring solutions.
• Experience in deploying prototypes for pilot projects or industrial PoCs.

What We Offer

• Opportunity to work on real-world connected systems and smart product development.
• Hands-on learning with IoT platforms, edge AI, and cross-functional projects.
• Flexible work hours and a collaborative team environment.
• Access to lab facilities and tools for rapid prototyping.
• Annual learning & development budget.
