Which technologist skills do employers want at the moment? It’s clear that, as we head into 2021, companies everywhere still have a powerful hunger for professionals who can manage products, work with data, and program in some of the world’s most popular languages.

Thanks to Burning Glass, which collects and analyzes job postings from across the country, we have some insight into the technology skills popping up most in open jobs over the past 60 days. Here are the top 25:

First, a bit of good news for technologists: We’ve been analyzing Burning Glass’s data for quite some time, and we can tell you that some of the top skills (such as SQL, Java, and Python) never seem to shift very much in the rankings. This is great, because it would be terrible to learn a popular skill only to see employers across the country abruptly stop needing it. Indeed, with any programming languages, there’s so much legacy code baked into existing applications and systems that companies couldn’t abandon them even if they wanted to.

Yet another good bit of news: These skills extend across the tech stack. If the most popular skills were clustered around a particular discipline, such as machine learning, data science, or artificial intelligence, that might present a problem to technologists who hadn’t spent years focusing on very specific languages, tools and methodologies. It’s clear from this list, though, that employers need a wide range of skills for an equally diverse set of projects.

If you’re interested in working with data in pretty much any capacity, it’s clear that learning SQL (structured query language) is essential. Created as a standardized language for relational database management, SQL is a vital part of many companies’ tech stacks; if you’re applying for an SQL-heavy job and want to stand out from other applicants, consider obtaining some certifications.  

Among programming languages, it seems that Java, Python, and JavaScript remain some of the most popular among employers, which is no surprise. If you’re adept with these, you’ll have little problem with recognizing the code backing many companies’ platforms and applications.

Although 2020 was an odd year in many respects (to put it mildly), it seems that employers everywhere are using 2021 to embrace and refine their long-term product roadmaps. Wherever you’re applying, make sure to research the company beforehand so you can tailor your application (and interview answers) to its particular needs and goals.
