Embedded Systems Engineer

Perfect Vision; Dammam; On-site; SAR 167,000 - 257,000; Full time

Job summary

Perfect Vision, a specialised connected telematics hardware and fleet management platform provider, is seeking an Embedded Systems Engineer in Dammam. You will design and build firmware in C/C++ for microcontrollers under RTOS or bare-metal, integrating sensors and connectivity to stream data to the cloud.

You will work on OTA update pipelines, low-power optimisations, and device-to-cloud data contracts with the platform team, while collaborating with hardware engineers during bring-up and field

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 CAN/OBD-II.

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 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.

Job description

Dammam, Saudi Arabia

Embedded Systems Engineer

Firmware for connected telematics devices — from sensor to cloud

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.

Company: Perfect Vision — specialized in connected telematics hardware and fleet management platform provider

Location: Dammam

Type: Full-time, permanent

• 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.
