Embedded Systems 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.

Job description

Firmware for connected telematics devices — from sensor to cloud

Company: Perfect Vision — specialized in connected telematics hardware and fleet management platform provider
Location: Dammam
Type: Full-time, permanent

About the Role

Our telematics devices run firmware that captures vehicle and asset data, processes it at the edge, and streams it securely to our platform. As Embedded Systems Engineer you will design and build that firmware — writing efficient, robust C/C++ on constrained hardware, integrating connectivity and sensors, and delivering the reliable over-the-air update pipeline our fleet depends on.

Key Responsibilities

• Design, write, and maintain firmware in C/C++ for microcontrollers, on RTOS (FreeRTOS/Zephyr) or bare-metal.
• Develop and integrate device drivers and low-level interfaces: UART, SPI, I2C, ADC, GPIO, DMA.
• Implement vehicle-data acquisition over CAN, OBD-II, J1939, and Modbus.
• Build cellular connectivity and telemetry using MQTT, TCP/IP, TLS, and (where relevant) CoAP/HTTP.
• Design robust over-the-air (OTA) firmware update mechanisms with rollback and integrity checks.
• Optimise for low power, memory footprint, and long-term field reliability.
• Work with hardware engineers during board bring-up and with the platform team on device-to-cloud data contracts.
• Write unit/integration tests, debug with JTAG/SWD, and support field diagnostics.

Required Qualifications

• Degree in Computer/Electronic Engineering, Computer Science, or equivalent, with 3+ years of embedded development.
• Strong C (and ideally C++) on resource-constrained microcontrollers.
• Hands-on experience with RTOS concepts, interrupts, and real-time constraints.
• Practical experience with serial/embedded protocols (UART, SPI, I2C) and at least one vehicle bus (CAN/OBD-II).
• Experience with cellular or wireless connectivity and MQTT/TCP-IP networking.
• Comfortable with hardware debug tools: oscilloscope, logic analyser, JTAG/SWD.

Nice to Have

• Experience shipping OTA update systems and secure boot.
• Familiarity with GNSS/GPS positioning and dead-reckoning.
• Knowledge of embedded security (TLS, key storage, secure elements).
• Exposure to CI for firmware and hardware-in-the-loop testing.

Inclusion & Diversity

At Perfect Vision, we believe in equal opportunity and are committed to creating a diverse and inclusive workplace. We warmly welcome and encourage applications from individuals with special needs (motor disabilities), as we provide fully equipped facilities and a friendly workspace designed to ensure they can perform their duties with the highest levels of comfort and professionalism.
