The role of the IoT engineer
The Internet of Things (IoT) engineer plays a key role in the design and management of systems that connect physical objects to the digital world.
IoT systems design
IoT engineers design complete systems, including sensors, actuators, communication networks and software platforms. They ensure that these systems can collect, transmit and process data efficiently.
Embedded software development
They program software for embedded devices (microcontrollers and microprocessors) that manage the functions of connected devices.
Integration of communication technologies
They integrate communication technologies such as Wi-Fi, Bluetooth, Zigbee, LoRa, NB-IoT and 5G to enable IoT devices to communicate with each other and with cloud platforms.
Data collection and management
IoT engineers design systems to collect data in real time from various sensors and store it securely. They also work on analysis platforms to process this data and extract useful information.
IoT systems security
They develop and implement security protocols to protect data and IoT devices against cyber attacks and unauthorised access.
Testing and validation
They carry out functionality, performance and security tests on IoT devices and systems to ensure their reliability and compliance with specifications.
Maintenance and updates
IoT engineers oversee the maintenance of existing systems and deploy software updates to improve performance and correct vulnerabilities.
The skills required
TheInternet of Things is a sector that requires a wide range of skills. To be an IoT engineer, you will need to have :
- Technical: Expertise in electronics, circuit design, embedded programming (C/C , Python), and wireless communication technologies.
- Networks: Understanding of network protocols, cloud architectures and communication infrastructures.
- Security: Knowledge of security principles for embedded systems and IoT networks.
- Data analysis: Ability to process and analyse data collected by IoT devices.
- Problem solving: Ability to solve complex technical problems and optimise systems.
- Project management: Ability to manage IoT projects from start to finish, from design to implementation.
The IoT working environment
IoT engineers can work in a variety of environments, such as :
- Technology and telecommunications companies.
- Start-ups specialising in IoT.
