How to Get a Job as an Internet of Things Engineer

In recent times, the concept of a ‘smart house’ where the occupant can control all elements of their living space with a simple gesture or voice command has been imagined as the future of housing. However, issues with internet connectivity have been an ongoing issue, making it difficult for smart houses and similar concepts to become a reality without the help of IoT and IoT developers.

IoT can be seen as a miniature version of the internet. To properly operate, sensors, user terminals, data storage and processing hardware, and operating protocols are all needed. IoT Engineers need to have an understanding of the sensors and other hardware components, the software and coding, and other areas such as cyber security, UI design, and communication protocols. In this article, we will cover what is required to become an IoT Engineer, the various paths that IoT Engineers can take once they meet the requirements, and some of the most common uses, terminology, and other relevant information about IoTs and IoT Engineers.

Qualifications of an Internet of Things Engineer

An IoT Engineer must possess a wide range of knowledge, both theoretical and practical, to be successful. This knowledge can be divided into two distinct categories, depending on the level of attention they require.

IoT developers need the following skills related to software:

Coding in JS, Java, or Python: As the range of libraries, frameworks and packages available for use in the Internet of Things (IoT) and across a variety of domains continues to increase, many modern high-level languages offer a wealth of features beyond that of their source code. As such, it is essential for developers working in the IoT to be proficient in at least one of these languages and their associated frameworks, packages and libraries.

Server-side frameworks, such as Node.js, Netbeast and Neura, can be utilised by IoT experts to assist in the development of Internet of Things applications. Server-side web development requires these frameworks to manage a variety of connected devices.

Here are some of the requirements for IoT developers in terms of hardware:

Sensors: Having a thorough understanding of sensors and their integration into new or existing system architecture is essential for any aspiring Internet of Things engineer. This familiarity is essential for collecting and sharing information with other parts of the network in near-real time, making it one of the most important prerequisites for IoT developers.

GPS: Today, many applications of the Internet of Things rely on real-time access to location data, making it a valuable skill for engineers who are looking for work in the fields of smart transportation, wearable technology, and logistics.

Technology for portable use: Wearables and smartphones are two examples of the mobile devices utilised in IoT systems. As evidenced in drone applications and transportation logistics, the hardware in question is not fixed but instead mobile in many IoT implementations. It is therefore essential for IoT engineers to be knowledgeable in the operation and upkeep of these portable devices.

In order to succeed as an IoT engineer, you need to have the following skill sets, all of which are data-centric.

Artificial intelligence and machine learning: Data analysis is an essential skill for any data analyst. It enables them to ingest, analyse and present large datasets in an informative manner. This will be particularly beneficial to engineers operating in the Internet of Things sector, as they are likely to encounter vast volumes of data.

Massive Quantities of data: It has been highlighted that a vast amount of data is generated by IoT devices, which must be evaluated quickly and accurately. Therefore, although machine learning and artificial intelligence have cross-over applications with Big Data, the skill set that Big Data encompasses, including the expertise of data managers, is essential for IoT engineers.

To Use the cloud: The key challenge associated with IoT data is storage, rather than the data gathering or analytics previously mentioned. That is why it is essential for potential IoT developers to be adept in managing large volumes of data on the Cloud.

Other Needed Qualities in IoT Engineers

User interface (UI)-focused design: It is critical that users of Internet of Things systems have full control over all system functions through the user interface. Additionally, the user interface should support cross-device collaboration. While this may be a challenging task, aspiring IoT engineers should seek to gain knowledge on the architecture of the underlying infrastructure in regards to the user experience.

Internet Safety: The scalability and complexity of Internet of Things (IoT) systems present them to digital or cyber security vulnerabilities. Although air-gapping can be a viable option to mitigate this issue, it is not always feasible. Therefore, it is essential that IoT developers have a sound knowledge of cyber security.

What IoT Engineers Need to Know About IoT’s Functioning and architecture:

The Internet of Things (IoT) architecture consists of four main levels, each responsible for a specific aspect of its operation. These four tiers are universal and can be applied to any IoT system, regardless of its size or complexity. The four layers are as follows:

Layer of sensing for information collection: The sensors and other associated devices that comprise this layer of the Internet of Things (IoT) system gather data from the physical environment and transmit it over the internet.

Transmission of data via a network’s uppermost layer: This encompasses items such as Data Acquisition Systems (DAS) and other networking hardware. The latter is what converts analogue sensor readings into digital information for usage by Internet of Things (IoT) apparatus. Should the network be configured to be connected to the internet, then sophisticated gateways are necessary to provide protection against threats such as malware and to filter incoming data.

A data processing layer that does: The following units process the information gathered in the initial layer. Here, the data is processed and then routed to a data centre, where it is available to various software applications. This layer of the Internet of Things (IoT) concentrates on the end user and their interaction with the numerous smart applications that are available. Devices with end-user applications in various sectors are encompassed by this category.

Common Concepts for Future Internet of Things Engineers

As an Internet of Things (IoT) engineer, there are certain terms and tools that you should be familiar with. It is important to understand some of the most fundamental IoT concepts, such as:

Blue tooth low energy (BLE): This Bluetooth variety requires less energy to operate, thus the name is indicative of its power efficiency. Unlike standard Bluetooth, it doesn’t need to be paired to work, and it is not intended for streaming video or music. However, it is ideal for small data packets which demand considerably less energy. Its many advantages make it an obvious choice for Internet of Things (IoT) developers.

Modulation of the pulse width (PWM): It’s a way to change the intensity of a light or the rate at which a motor spins from a digital signal to an analog one.
