Every once in a while I query the job search engines to see what’s out there these days. I first did this in February, 2013, and have looked at them again every few months since then.
I especially like to look at Dice.com because most of those jobs are for contractors, and when businesses can't find full-time employees with certain skills -- such as new programming languages -- they hire contractors. This is also an indication of new projects that businesses are staffing up for.
I've only looked at Scala job posting data a few times, and here are the Dice.com results:
Dice "Scala" results -------------------- June, 2014 - 411 July, 2013 - 309 Feb, 2013 - 230
By percentage, Akka job listings on Dice have jumped even more. I only have two data points, but here you go:
Dice "Akka" results ------------------- June, 2014 - 93 July, 2013 - 18
The sections that follow show the other data I found this earlier this year and last year.
Here are the results of searching for “Scala” at each of the job search engines in June, 2014:
I also searched for Akka jobs, and found these numbers:
I don’t trust Indeed for data like this; they keep postings around forever and also have duplicates.
On July 1, 2013, I took the time to do a few more searches, this time for a variety of keywords, and this is what I found:
I did this first back in February, 2013. Back then I only searched for “Scala” programming jobs, and this is what I found:
I don’t trust the data from indeed.com. They list jobs multiple times, and keep things online forever, so I don’t look at them any more, not for data like this.
As mentioned earlier, Dice lists contracting jobs, so with a new technology like Scala, I think they’re a decent indicator of the coming market. (That’s just my opinion, though.) I know that when I worked at a NASA subcontractor, we hired contractors either because (a) they were much better than other people we could hire, or (b) because they knew an up-and-coming technology we didn’t know.
