Each represents a single, unified solution, overcoming challenges and taking brands direct-to-consumer. Our client portfolio includes globally recognised brands such as Coca-Cola, Nestle, Elemis, Homebase, and Proctor & Gamble. In this role you will be responsible for one of THG Fulfil's largest and most complex accounts, spanning B2B/channel and B2C/D2C fulfilment, inbound and new product introduction (NPI), value-added services, systems integration, and commercial administration, with direct exposure to both client leadership and THG group executives. The Role This is one of the most strategic, highest-visibility accounts in the Fulfil portfolio, and a newly created, dedicated role to match.

With that comes genuine ownership. The successful candidate will be THG's primary point of contact for the client's operational, logistics and programme teams, translating their requirements into internal action across warehouse operations, transport, IT/integrations, ISC and commercial — and holding those teams to delivery. They will own the account's governance calendar and daily reporting, resolve escalations end-to-end, and hold credible technical conversations on integrations without needing to do that work personally. This is a role for someone who wants to run something significant, not administer it. Why This Role Real seniority from day one: of one of Fulfil's largest and most complex accounts — you're the person in the room with senior leadership on both sides, not a supporting player.
