Remember the key to a long and successful IT career is to maintain and grow your key skills.
What is the half-life of your staff’s IT knowledge? In 1962, economist Fritz Machlup coined the phrase “knowledge half-life” to describe the time it takes for half the knowledge in a particular domain to be superseded. You probably will not be surprised to learn that the half-life of IT knowledge decreases every year.
According to a recent article in the IEEE Spectrum, the half-life of an IT professional’s career is now about 10 to 12 years or perhaps even less. Staying relevant for even that amount of time takes dedicated, ongoing self-education, also known as “upskilling.”
Data scientist and user interface developers are two of the fastest growing job titles in the past three years, according jobs related data from TheLadders.
Job openings in both positions have multiplied 12 fold since 2010, TheLadders said. By comparison, all jobs tracked by the company grew on average 1.4 times over the same period.
The jobs growth ranking was determined by analyzing the words and phrases people used to search for jobs and the types of positions employers posted over the past several years.
Here are the five fastest-growing job titles over the past three years:
Data Scientist and User Interface Developer
Both of these positions grew 12 times over the last three years. Today, TheLadders has more than 200 listings open for data scientist positions, as opposed to less than 50 openings three years ago.
iOS- and Android Developer
This job increased tenfold since 2010. TheLadders now has more than 500 positions open for mobile development.
User Experience Designer
This position hasn't grown as fast as user interface development, but it's still up seven times in the past three years.
Business Intelligence Developer
It is all about analytics and Big Data today. Over the last three years, this job has grown sixfold.
Many of these jobs were nonexistent five years ago and some of the more traditional job titles now rank among the most rapidly declining.
Over the past five years, the growth rate of titles containing the word "manager" has dropped 25% and the growth rate of ones with the word "director" has dropped 50%. TheLadders considers that a sign that mid-level management jobs as a whole are becoming less popular.
