WIG is a membership charity that is building a community of leaders across public, private and not-for-profit sectors. 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 is a small, ambitious and hardworking team that punches well above its weight, delivering cross-sector collaboration at the highest levels. With a lean structure of around 34 colleagues, every person’s contribution is visible and valued. The organisation is in a period of strategic growth, investing in new capabilities, regional expansion and evidence-building to deliver against a five-year strategy running to 2029. The Membership Manager sits within the Membership & Marketing directorate, reporting to the Head of Membership. The directorate brings together three interrelated functions; Membership, Partnerships and Marketing, under the leadership of the Director of Membership & Marketing and is responsible for driving sustainable growth through member value, business development and targeted marketing. 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. With a passion for public policy and cross-sector collaboration, you will ensure high levels of engagement, retention and satisfaction, acting as a trusted point of contact and advocate for member needs. The right candidate will be energised by working at the intersection of policy, leadership and cross-sector collaboration. They will be comfortable engaging with senior stakeholders across all sectors, commercially minded in their approach to member development, and motivated by the chance to contribute to an organisation that is actively shaping how the UK’s leaders work together. The Membership Manager is recognised across WIG as a confident, credible and trusted point of contact for members, contributing actively to the directorate’s culture of high performance and commercial accountability.
