Embedded Telematics Firmware Engineer (C/C++)

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.
