Electrical and Electronic Engineer (Embedded System Specialized) at Softroleum Limited

We’re looking for a hands-on Electrical and Electronic Engineer with practical Embedded Systems experience, including at least 1 year of real-world experience in electronics, firmware development, or IoT integration.

You’ll join us in designing and prototyping custom smart devices powered by microcontrollers like ESP32, integrating sensors, and enabling cloud connectivity. The work is varied — from building rugged field devices to low-power IoT solutions.

Responsibilities

• Design and prototype microcontroller-based circuits (preferably ESP32 or STM32)
• Integrate and interface sensors (GPS, temp/humidity, vibration, air quality, etc.)
• Write and test firmware (Arduino, ESP-IDF, or bare-metal C)
• Work with communication modules: GSM (SIM800L/7600X), LoRa, or WiFi
• Send sensor data to remote servers or APIs
• Design custom PCBs using KiCad (or similar)
• Participate in hardware debugging, documentation, and basic testing
• Installing devices on-site for customers.

Requirements

• Minimum 1 year of hands-on experience in embedded systems or IoT
• Ability to work with ESP32, Arduino, or similar platforms
• Comfortable using soldering tools, breadboards, and test equipment (multimeter, logic analyzer)
• Familiar with I²C, UART, SPI, and basic power supply design
• Able to read datasheets and follow sensor integration guides
• Experience working with at least one SIM or GSM module
• Familiarity with basic HTTP or MQTT protocols for data transmission

Bonus Skills (Nice to Have)

• PCB design experience with KiCad or EasyEDA
• Understanding of low-power design or battery-powered systems
• Web APIs or backend programming is a huge plus
• Mechanical design or experience with enclosures (3D printing, etc.)
