For over 40 years, WIG has brought together senior decision-makers and thought leaders from business, government and civil society to tackle the challenges that matter most to the UK’s future.

This role is central to WIG’s membership proposition. The Membership Manager will build, manage and deepen relationships with portfolio of WIG’s 250+ member organisations spanning government, industry and the not-for-profit sector, while also playing a key role in securing new members and expanding WIG’s cross-sector community.
