-## Background
-
-Autonomic is a worker-owned co-operative of queer comrade hackers dedicated to using technology to empower people making a positive difference in the world. Since 2017, we’ve been successfully delivering projects in a range of sectors including renewable energy, labour organising, independent media, feminist research, migrant solidarity activism, sustainable fashion, and arms trade abolition.
-
-We are currently 11 worker-owners, located in 6 countries. We are a Co-operative Society, registered in the UK with the Financial Conduct Authority. Legally, we are a freelance consortium, which means that we operate as a group of self-employed contractors, and are responsible for our own individual income tax.
-
-Autonomic aspires to follow the [7 co-operative principles as defined by the International Co-operative Alliance](https://www.ica.coop/en/cooperatives/cooperative-identity).
-
-
-## Pay

-Everyone in the co-op will always be paid the same rate, which we decide on collectively and adjust according to how well we’re doing.

-### Required skills

-## Process
-
-People of color, women, genderqueer, non-binary and trans folks, neurodiverse and queer folks are strongly encouraged to apply.
-
-Email [hello@autonomic.zone](mailto:hello@autonomic.zone) with your CV (it really doesn’t have to be fancy, just a list of work) and a little bit about yourself and what you’re looking for work wise.
-
-If we think you might be suitable for these roles, you’ll be invited for a few chats with members of the co-op who will show you more about the kinds of work we do and be able to answer any questions you have.
-
-If we want to take you on, we’ll then have a vote amongst our members and you can start working for us right away as a “potential member”. After ~100 hours of work you can be invited to join the co-op as a full member.
