Despite many companies’ efforts to draw tech professionals back to the office, remote work remains immensely popular. Which remote tech jobs have enjoyed an increase in open positions? Let’s break it down.

According to CompTIA’s monthly Tech Jobs Report, software developers, project managers, data scientists, and those involved in cybersecurity all saw a month-over-month increase in remote job postings. Here’s the full breakdown:

(A note on methodology: CompTIA relies on data from the U.S. Bureau of Labor Statistics (BLS) as well as Lightcast, which collects and analyzes millions of job postings from across the country.)

For months, some of the biggest companies in tech have done their best to convince tech professionals to return to their former office desks. In each of these cases, executives have claimed that in-office work boosts collaboration and camaraderie. “It’s easier to learn, model, practice, and strengthen our culture when we’re in the office together most of the time and surrounded by our colleagues,” Amazon CEO Andy Jassy wrote in a Feb. 17 memo to employees. “Of course, there will be plenty of meetings that will have significant virtual participation, but having more in-person interactions helps people absorb the culture better.”

But tech professionals have prized the flexibility that comes with remote work, as well as the opportunity to work for companies in other parts of the country. Via a LinkedIn poll in March, Dice asked tech pros if they’d quit their all-remote job if their company issued a return-to-office mandate—and 42 percent of respondents said they would. 

With the leverage generated from the low tech unemployment rate and companies’ need for tech professionals with a variety of specialized skills, many job candidates are negotiating for remote or hybrid work as a condition of signing with a particular organization. If your future (or current) boss seems reluctant to allow you to work from home, propose a pilot or A/B test.
