Developing applications for the IoT requires knowledge and skills in many areas, from hardware design and network design to low-level and high-level programming languages.

Even if an IoT Engineer is focused on developing a part of the system (it can be connected devices, the networks over which they interact, IoT platforms or applications for end-users), they need to understand the principles of each part as well as the whole concept.

Very few vacancies are posted in the domain of the Internet of Things . But it's not because no one needs IoT engineers. It's just that companies usually search for them with the help of recruitment agencies.

Job responsibilities

  • Develop the architecture of IoT solutions
  • Design and configure networks
  • Prototype devices
  • Develop interfaces for user interaction with the IoT system
  • Interact with hardware and software vendors on technical issues
  • Install and configure hardware and software, integrate with related systems
  • Ensure the cybersecurity of IoT systems.

Since the IoT domain is new and complex, an Engineer has to take on some tasks that a Project Manager usually performs. This may include discussing solutions with the customer, preparing documentation, forming a team, and participating in the search and selection of contractors for the project.


  • Knowledge of the theory of process analysis
  • Understanding of connected devices 
  • Proficiency in the languages and development environments required for prototyping devices: C / C++, Python, JavaScript, Arduino
  • Knowledge of languages for developing web and mobile applications for interacting with IoT devices: Java, Swift, Node.js
  • Knowledge of data exchange protocols: MQTT, CoAP, AMQP, Websocket, XMPP-IoT, REST
  • Experience with IoT platforms: Samsung Artik, Intel Edison, Arduino, Raspberry, BeagleBone, SparkFun, FPGA
  • Experience with Cloud platforms: Samsung Artik Cloud, Microsoft Azure IoT Suite.
  • Network design skills and knowledge of network standards, protocols (in particular, wireless communication protocols: BTLE, ZigBee, LPWA, 6LowPAN, Z-Wave, SigFox) and network technologies (Wi-Fi, Low Energy Bluetooth, RFID)
  • GPS programming skills 
  • Strong understanding of IoT security principles.

For the IIoT (Industrial Internet of Things), experience with SCADA systems and industrial controllers (IEC 61131-3) would be a plus.


We have collected answers to the most common questions about searching for IoT engineers. If you need more information, INDIGO Tech Recruiters will be happy to provide it to you.

1. Who most often hires IoT engineers?

Startups, large technology companies (IBM, Microsoft, Intel, SAP, Vodafone, Verizon, Fujitsu), IT divisions of government organizations and banks, large online stores, and taxis.
To work in the IIoT, a specialist will have to learn more about the subject area (the industry for which the solution is being developed) and learn how to develop specialized sensors and software. Examples of using the IoT concept in manufacturing include equipment management, predictive analysis, and accident prevention.
Monitor the market in this area, attend industry events, meet engineers directly, contact them via LinkedIn to offer jobs and ask for recommendations. Or hire a Recruitment Agency with a solid database and a network of personal contacts.
