This is a key hire for me, all the frontend engineers in my team are contract at the moment and you'd be my first permanent frontend specialist. The team is cross-functional so you'd be working with backend engineers and QA folk on the day-to-day, and regularly talking to our DevOps, SA and Product teams too. NB the company is also hiring for a bunch of other posts, see jobs.nominet.uk.
We run DNS for the .uk domain space, and a growing number of other TLDs as well. My team is currently working on a complete re-write of our flagship customer UIs used by domain owners, sellers and TLD admins.
