FAQ about the IoT Engineer

What is an IoT engineer?

An IoT engineer is a specialist in designing and deploying connected systems. They design embedded devices, integrate sensors and communication modules, develop data collection and analytics applications, and secure IoT infrastructures. Their role is essential across sectors as varied as industry, healthcare, smart cities, and connected agriculture.

What is the salary of an IoT engineer in France?

In France, a junior IoT engineer typically earns between €40,000 and €55,000 gross per year. A mid-level profile ranges from €50,000 to €75,000, and a senior can reach €70,000 to over €100,000. Profiles combining embedded expertise, cloud, and IoT cybersecurity are particularly sought after and command higher salaries.

What is the difference between an IoT engineer and an embedded engineer?

An embedded engineer focuses on hardware and embedded software within specific devices. An IoT engineer has a broader scope: they also manage network connectivity, cloud platforms, analytics on collected data, and communication security. In practice, IoT incorporates embedded as a component, but adds the full communication and data processing ecosystem on top.

What skills do you need to become an IoT engineer?

You need to master embedded programming (C/C++, Python), IoT communication protocols (MQTT, CoAP, LoRaWAN, Zigbee), IoT cloud platforms (AWS IoT, Azure IoT Hub, Google Cloud IoT), and have solid cybersecurity foundations. Knowledge of microcontrollers (Arduino, ESP32, STM32) and embedded operating systems (FreeRTOS, Zephyr) is also essential.

What are the responsibilities of an IoT engineer?

Their responsibilities include designing connected embedded systems, programming and integrating sensors and actuators, developing IoT data processing applications, setting up appropriate communication networks, securing systems against cyberthreats, and testing and maintaining deployed solutions.

What tools does an IoT engineer use?

They use development boards (Arduino, Raspberry Pi, ESP32), IoT cloud platforms (AWS IoT, Azure IoT, Google Cloud IoT), network analysis tools (Wireshark), embedded development environments (IAR, Eclipse), and languages such as C/C++ and Python. Data visualisation tools (Grafana, Node-RED) are also part of their toolkit.

What training is needed to become an IoT engineer?

A Master's-level degree in computer science, electronics, or telecommunications with an IoT or embedded systems specialisation is typically required. Engineering schools with IoT, embedded systems, or connected networks programmes are best suited. Cloud certifications (AWS IoT, Azure IoT) and specialised IoT cybersecurity training are a valuable plus.

How does an IoT engineer's career evolve?

An IoT engineer can progress to IoT project manager, IoT architect, or head of an IoT department. Some specialise in connected device cybersecurity, a fast-growing area. Others move into solution architect roles at cloud providers or IoT platform vendors.
