Scala Adoption

Word on the street is that Scala is increasingly being used by Java developers as a “Better Java”. As a longtime Java developer I find this language very appealing, something which has many of the same strengths as Java, but which is more expressive. In order to get an idea of Scala adoption in the wild I did some basic research and found some interesting results.

The job search site has some very neat trend identification tools. The graph below shows the rapid up-tick in Scala adoption in recent times:

The absolute percentage of Jobs listing mentioning Scala is still low, but the growth trend is clear.

Since I’m curious to find out who is using Scala I combined the list of organisations known to be using Scala from the official Scala website with some sleuthing around the job ads. I combed through the job ads on listing Scala and put together a list of well known organizations listing Scala in their job ads*. Combined with the organizations listed on the Scala website I get the following (in no particular order):

  • HP
  • Twitter
  • Google
  • eBay
  • VMware
  • Oracle
  • Amazon
  • Accenture
  • eHarmony
  • Coca-cola
  • tumblr
  • University of California Berkeley
  • McGraw Hill
  • Heroku
  • Foursquare
  • LinkedIn
  • the Guardian
  • Morgan Stanley
  • Credit Swiss
  • UBS
  • HSBC
  • AT&T
  • University of Arizona
  • General Dynamics
  • Thomson Reuters
  • Deutsche Bank Global Technology
  • Huawei
  • Standard and Poor’s
  • AOL
  • Yammer

*Note that the Job ad simply needed to list Scala to be included here, which doesn’t mean that the organization is necessarily using it extensively (or even at all, in a few cases ads would say “knowledge of a functional language like erlang, Scala or Haskell an advantage” or similar). Even with that caveat in mind the list of organizations taking notice of Scala is very impressive indeed!

  1. I think it’s easy for Scala to show this huge improvement, simply because its contribution to the job market is still too low (so any increase, even the slightest, will strongly affect the chart).

  2. Thanks for the post. There are currently (27 Jan 2012), 765 jobs matching ‘Scala’ on This is significant enough for the trend to be meaningful.
