If you work in tech in Europe, lots of people are already on mastodon.

#fedihire hashtag on Mastodon is as close as it gets.

This probably won't help you, but there was Flockingbird. However its attempt to index Mastodon's job offers ended up in drama as Mastodon generally does not like being indexed...

Just use Mastodon.

Search for tech coops, quite a few seem to be popping up recently. I’m not directly in tech and still haven’t found who I’d really love to work for, so I can’t help much, but it’s a lovely question and I’m curious about other people’s answers!

It’s not a Federated platform like LinkedIn, but I am working on CareerCupid , a “OkCupid for jobs” website where people can answer questions about their values and goals, and then find out people that are the most compatible to work with. The website does work with ActivityPub though, you can follow @thecupid@cupid.careers and you can see the new polls and job listings published on the website.

In a way LinkedIn is federated. You create a profile or post, and within minutes hundreds of shady data brokers and contact details resellers have a copy of your post available for their customers!

I don’t really see the benefit, though. LinkedIn is functionally almost the same as Facebook, and can be replicated by adding a theme to a Friendica instance with a few custom fields. The biggest difference is that LinkedIn allows recruiters to spam and stalk youoffer you jobs, other than that it’s just Facebook where most adults have decided to only talk about work stuff.

Nope. There is none as I'm aware off.

You mean like LockedOut?
