Resident SRE @ IO Global

Maybe you didn’t know, but IOHK / IO Global is a long time corporate driver within the entire Nix ecosystem.

Important functions of our company like DevOps & SRE being born out of the Nix ecosystem spirit, we open source (almost) everything we do based on our open-source-by-default policy.

At the heart of Nix@IOG, we are looking for a couple of folks to complete our exquisite Resident SRE team, of which I attached the role description below.

If you’ve got the skills and/or are hungry and thirsty to learn a ton, please join our team partly constituted of ex-release managers for Nixpkgs, like @nrdxp, @jonringer or @disassembler , whom you can ping for technical questions about the job at any time.

Once you want to get more serious about your application or for any HR-related questions, please contact @Posh or @IOHKDaveR in a DM.

Welcome to our Team!

  • We are particularly interested in people with experience of Nix, Open source work and Functional and/or Statically Typed Languages
  • You will be someone who works well on your own and with a team

  • You are kind and respectful of others’ opinions and you are open and act with integrity when engaging in academic or technical discussions

Great work Blagg! Keep it up!

Our flagship project, Cardano, is currently looking for a new Resident SRE, here’s how its new office space looks like:

It’s all there, in the open. :slight_smile:
We’re also still looking for Resident SREs for a
cuple of non-open projects. But their office spaces look indeed quite comparable.

You understand the benefits of monorepos?

Please DM @Posh!
