How to Hire Top IoT Specialists
How to hire an IoT specialist
If you’re creating a fully-fledged distributed IoT service, there are many angles to consider: development of the embedded device itself, the IT and networking services that power it, data and analytics, and design and development of an integrated UI (e.g., a mobile app to control your home’s thermostat).
To hire the right IoT specialist, you’ll need to
Choose your hardware platform (i.e., your processing board)
Develop the application software, including any back-end and networking support
Create the integrated UI
Develop the APIs, beacons, web sockets, and procedure calls that enable the high-level communications that occur between devices
Establish security, data storage, and analytics measures
To get started, you’ll need a platform for the product development team to develop and launch the product on, then consider both hardware and software systems. An IoT pro can help recommend the kind of power and operating system you’ll need on the hardware side that’s appropriate for your device or prototype.
IoT programming languages used to be unique to embedded systems, but now this software uses more common languages that web developers already know and use. IoT programming languages range from general-purpose languages like C++ and Java to embedded-specific choices like Google’s Go language or Parasail. Each offers a few advantages and disadvantages. Your developer will be able to advise you which is best.

Internet of Things FAQs
Frequently asked questions
What is IoT development?
Internet of Things (IoT) development projects are everywhere, and affordable, advanced technology is the driving force behind this fast-growing phenomenon. Smaller, more accessible hardware and the flexibility to use common programming languages make it easier than ever before to develop these embedded IoT systems. From hobbyists programming their own single-board computers to companies developing devices we can control from our mobile devices, the IoT is rapidly expanding.

From hobbyists programming their own single-board computers to companies developing devices we can control from our mobile devices, the IoT is rapidly expanding.
Why hire IoT specialists?
Whether you’re creating a quick prototype or an entire IoT-powered business application, you’ll need an IoT developer to help with the data, hardware, and software considerations of your IoT initiative. From a development standpoint, creating IoT devices hinges on embedded programming. There are both software and hardware angles to consider when creating an IoT prototype—the small computer embedded in the object or device, and the software that makes it run. As mentioned above, this includes things like wearables, connected home devices, circuit design, GPS programming, 3D design, and more.
Fortunately, many of these software systems and software development kits (SDKs) now use programming languages and operating systems that engineers already use for mobile and web development, which opens the field up to many more developers.
