Technology is constantly evolving and so, too, are the developer skills employers look for to make the most of what is emerging and what is solidifying its place in the enterprise.
As companies dive deeper into digital transformations and pivot to data-driven cultures, tech disciplines such as AI, machine learning, internet of things (IoT) and IT automation are driving organizations’ technology strategies and boosting demand for skills with tools, such as Docker, Ansible and Azure, that will help companies innovate and stay competitive in rapidly changing markets.
“What we’re seeing is companies developing internal ‘skill maps’ within their developer organizations so they can see what skills they have, and where they need to grow,” says Vivek Ravisankar, CEO and co-founder of HackerRank. “They’re building these competency frameworks to find their skill gaps and then put in place training and education to close those.”
Understanding which disciplines and skills are up-and-coming and which are fading can help both companies and developers ensure they have the right skills and knowledge to succeed. And what better way to find that out than to mine developer job postings.
Indeed.com analyzed job postings using a list of 500 key technology skill terms to see which ones employers are looking for more these days and which are falling out of favor. Such research has helped identify cutting-edge skills over the past five years, with some previous years’ risers now well establish, thanks to explosive growth. Docker, for one, has risen more than 4,000 percent in the past five years and was listed in more than 5 percent of all U.S. tech jobs in 2019. IoT as well has shot up nearly 2,000 percent in the past half-decade, with Ansible — an IT automation, configuration management, and deployment tool — and Kafka — a tool for building real-time data pipelines and streaming apps — showing similarly strong growth. And, of course, the rise of data science has also since cemented high demand for a range of skills, including artificial intelligence, machine learning, and data analysis.
Developers looking to add new skills to their repertoire should pay close attention to the most recent upticks in skills demand that Indeed identified from September 2018 to September 2019 — and those falling out of favor — as outlined below. Each skill is accompanied by average annual salary information for developers who possess these skills, according to PayScale.com.
Pytorch is an open-source machine-learning library written in Python, C++ and CUDA. It is used for applications such as computer vision and natural language processing. While primarily developed by Facebook’s AI Research Lab, it’s offered free under the modified BSD license.

Kotlin is a cross-platform, statically typed, general-purpose programming language that’s designed to interoperate with Java. The Java Virtual Machine (JVM) version of its standard library, in fact, depends on the Java Class Library, though Kotlin’s syntax is more concise than that of Java. In May of 2019, Google announced that the Kotlin language is now its preferred language for Android developers, and has been included as an alternative to the standard Java compiler since the release of Android Studio 3.0 in 2017.
