ARE YOU THE PERSON WE NEED? Are you organised, proactive, and enjoy being a reliable support to a busy team? We need someone who takes pride in keeping operations running smoothly – the kind of person who spots what needs doing, tackles tasks with a positive attitude, and values being part of a team making a real difference.
This is an exciting time to join our small but dedicated team as we approach our 50th anniversary in 2026. This varied role provides essential administrative support that helps us deliver on our mission. The role is 21 hours per week with flexible working arrangements across the week to suit your needs, with at least one day in our Hammersmith office. We need someone who enjoys variety, is comfortable working independently, and takes satisfaction in contributing to the team’s success.
You’ll provide varied administrative support including managing correspondence, processing post, sending membership materials, and helping with event administration. You’ll maintain accurate records by entering data into Salesforce (our customer relations database), checking reports match, and organising documentation. You’ll also help keep the office running smoothly by liaising with suppliers and assisting with health & safety compliance.
You’ll have experience in general administrative roles with strong organisational skills and excellent attention to detail. You’ll be proficient in Microsoft Office (particularly Excel), reliable, proactive, and able to work independently whilst being a supportive team player. Experience with Salesforce is desirable but not essential.
