About Thirty HR

Thirty HR is an HR consultancy supporting clients across a range of industries, from recruitment and HRIS to employee relations, with hands-on, on-site HR support for founder-led, fast-scaling brands. We typically work with businesses at the 5 to 100 employee stage, giving them the calibre of HR support you'd expect from a full-time hire, without the overhead.

We're a modern team, forward-thinking in how we work. We don't just advise from the sidelines, we're hands-on and feel like part of each client's team.

We're growing, and we're looking for an HR Administrator to join us and help deliver brilliant HR support across our client portfolio.

The role is based in either London or Redhill.
