Embedded Telematics Firmware Engineer

Perfectvisionksa; Saudi Arabia; On-site; SAR 120,000 - 180,000; Full time

Job summary

Perfect Vision in Dammam is searching for an Embedded Systems Engineer to design and implement firmware for telematics devices. You will write efficient C/C++ code for constrained MCUs, integrate drivers and sensors, and ensure secure OTA updates for fleet devices.

The role involves RTOS usage (FreeRTOS/Zephyr) or bare-metal, driver development, and near-term field reliability with a focus on low power and robust data transmission from vehicle buses to cloud platforms.

Qualifications

• 3+ years of embedded development in C/C++ on resource-constrained hardware.
• Experience with RTOS concepts, interrupts, and real-time constraints.
• Hands-on with UART/SPI/I2C and vehicle buses (CAN/OBD-II).

Responsibilities

• Design, write, and maintain firmware in C/C++ for MCUs on RTOS or bare-metal.
• Develop device drivers and low-level interfaces (UART, SPI, I2C, ADC, GPIO).
• Implement vehicle-data acquisition over CAN/OBD-II/J1939, Modbus where applicable.
• Build cellular connectivity and telemetry using MQTT/TCP/IP/TLS.
• Design OTA firmware update mechanisms with rollback and integrity checks.
• Optimise for low power, memory footprint and field reliability.
• Collaborate with hardware and platform teams; support field diagnostics.
