My understanding is that the New York Times is a big Perl shop out there in thems back offices

Last I heard, DuckDuckGo backend was Perl.

Raku (Perl 6) is interesting as well. I have a feeling that nobody (of significant size) adopted it in production.

Perl is not trendy. Companies, even those that use it extensively never communicate about it and there are no publicly visible ads on job boards. Doesn’t mean that there’s not code to maintain and projects building up.

Personally I never had a Perl contract by searching for the companies. I identified as a Perl specialist on my LinkedIn profile and some people searching for help contacted me.

Recently I have been contacted by some headhunters for something about « defense » in UK but did not manage to know more about it. Also check « aviation in Brusells », or « billing, payment, finance » in France.

For public sector: EPFL (Lausanne science and technology university and labs) and Genève public judiciary system. May be in the process of rewriting to other languages, as booking.com does (Java notably). But there will be legacy code still.

Also, banks!
