As in January 2018, demand for software developers was higher than for any other tech role, followed by computer user support specialists, with postings up 80% year-on-year, and computer systems engineers, up 32% year-on-year.
As for which type of software developer skills are being sought, recent figures indicate the usual collection of well-established languages are most frequently asked for.
The same languages are being sought in the UK, with figures from IT Jobs Watch citing all three languages as being among those most commonly asked for in job postings.
Alongside these languages, employers typically demand various related skills, according to careers site Dice, with postings often requiring Java developers to be experienced in building enterprise-focused apps using Java EE, in creating server-side Java servlets, in using the Spring application framework and familiarity with the Hibernate framework for mapping Java classes to database tables.
For Python, the broad range of skills asked for reflecting the language's versatility. On the web development side, employers commonly ask for experience with the frameworks Django and Flask, while for data science roles common requests are for expertise in using the machine learning-related libraries sci-kit-learn, Theano, and Keras, as well as a background in carrying out predictive and statistical modeling.
One notable absence among the most in-demand tech jobs was a data scientist, which was named the most promising tech job of 2019 by both LinkedIn and Glassdoor, with LinkedIn reporting the number of job postings for data scientists growing 56% year-on-year during 2018.
That contrast may stem from the number of data scientists roles growing rapidly but from a relatively small base or differences in how the US Bureau of Labor Statistics categorizes roles.
Overall, the number of job posting for the IT sector in the US continues to rise, up 3% to 4,627,800 year-on-year in January 2019.
