Our people are central to the success of the business, and we are looking for an organised, proactive and people-focused People Operations & Office Assistant to provide administrative support across our People Operations function, while also assisting with the effective running of our offices.

This is a varied role that would suit someone at the beginning of their HR career who is keen to gain practical experience across the employee lifecycle. It may be particularly suitable for someone interested in developing their HR knowledge and studying towards a CIPD Level 3 Certificate in People Practice.

Role Overview

The role will primarily support the People Operations Manager, while also working closely with the Office Manager to assist with the smooth running of Firstco’s Central London Head Office and Heathrow Office.

This is a hands-on position requiring excellent organisation, attention to detail, discretion and a willingness to support a broad range of activities. It offers a strong foundation for someone looking to build a long-term career in HR and People Operations, while gaining additional experience in office administration and business support.

The role is full-time, five days per week, with a hybrid working pattern. The successful candidate will be expected to work three days per week from the office, split between Firstco’s Central London Head Office and Heathrow Office, with the remaining days worked remotely.
