Location: Trivandrum, Kerala – On-site

Company: AppleBerry Technologies

Employment Type: Full-time

About the Role

AppleBerry Technologies is looking for freshers with strong hands-on interest in Embedded Systems, Medical Devices, and IoT .

This role is intended for candidates who have already built hobby, personal, academic, or self-initiated embedded projects . Candidates with only theoretical knowledge and no practical project experience are not suitable.

Our Philosophy In the AI era, we believe every embedded developer should grow into a complete product developer .

A developer should be capable of taking a product from idea to implementation by combining strong engineering fundamentals with the efficient use of AI tools.

This includes

Requirement → Circuit Design → PCB → Firmware → Debugging → Integration → Testing → Working Product

AI tools should be used to accelerate research, coding, debugging, documentation, and development, but the engineer must understand and validate the final solution.

Key Responsibilities

- Design and debug analog and digital electronic circuits.
- Develop embedded firmware using C/C++.
- Work with STM32, ESP32, ARM-based MCUs, or similar platforms.
- Interface sensors, displays, communication modules, and peripherals.
- Work with UART, SPI, I²C, ADC, PWM, timers, and interrupts.
- Develop schematics and PCBs.
- Perform hardware bring-up and troubleshooting.




- Work on IoT and medical-device related products.
- Use AI tools effectively for firmware, debugging, research, and product development.
- Gradually take ownership of complete product development.

What We Look For Our interview will mainly assess robust fundamentals in:
- Basic electronics
- Analog and digital electronics
- Microcontrollers
- Embedded C/C++
- Firmware development
- Circuit debugging
- Sensors and communication protocols
- Reading schematics and datasheets
- Practical problem solving

Candidates should be able to clearly explain their own hobby or personal projects, including what they built, problems faced, and how they debugged them.

Added Advantage

Experience with any of the following is a plus:
- PCB design using KiCad, Altium, Eagle, or similar tools
- STM32 / ESP32 / Raspberry Pi
- FreeRTOS
- BLE, Wi-Fi, MQTT
- Medical electronics
- Python
- Embedded Linux
- 3D design using SolidWorks, Fusion 360, FreeCAD, or similar tools

Who Should Apply Apply if you are a fresher who enjoys building electronics, has practical embedded project experience, is comfortable with both hardware and firmware, and wants to become capable of independently developing complete products.

If your embedded-system experience is limited only to classroom theory or copied tutorial projects, this role may not be the right fit.
