We are seeking a highly dedicated and motivated HR Administrator to join our HR Service Delivery team to support the onboarding of new colleagues via acquisitions, as we continue to grow our business in the UK & EMEA. This is a hybrid role, based part of the week in our modern city centre Chelmsford office which is easily commutable via train and bus, and part of the week available to work from home (after initial training in the role has completed).

Experience in a similar HR Administrator role where you have gained experience working on acquisitions, or as a Recruitment Administrator would be ideal. However, we would welcome applications from candidates from a non‑HR background who have demonstrable experience working in a fast‑paced process‑driven environment working on administrative compliance, data auditing and reporting tasks. Internally we brand our HR Service Delivery team roles as ‘HR Specialist’ and offer a potential career path to ‘Senior HR Specialist’ and beyond.

We are proud that our HR Service Delivery team is viewed as a future talent pool for career paths both within our HR Operations team and across our Divisional HR teams with opportunities for progression into roles such as HR Advisor, HR Business Partner, HR Data Analyst and roles within Reward, Benefits and L&D.
