Experienced Marketing Consultant | Change Management

Your Challenge You have built your career in consulting. You know how to frame a problem, earn the trust of senior stakeholders and move a project from insight to impact. Now you want to anchor that experience in marketing and in the business questions it shapes. At The House of Marketing, part of Customer Collective, you join clients from various industries on strategic marketing consulting and interim management projects. One assignment might ask you to shape a strategy and guide a leadership team through the choices it involves. The next might place you inside a client organisation, taking ownership of a role and delivering from within. Often it is a combination of both. What stays constant is the need for sharp thinking, sound judgement and a willingness to roll up your sleeves. You bring expertise to the table from day one. You own workstreams or full projects, work directly with senior stakeholders and help clients turn complex questions into decisions they can act on. Alongside a solid marketing foundation, you bring a clear specialist spike in Change management. That spike is what makes your contribution distinctive, and our clients will rely on it.

What you'll do
• Lead and deliver client projects. You own strategic marketing projects or workstreams, from framing the problem to delivering the outcome, on time and with impact.
• Work with senior stakeholders. You build trusted relationships with client leadership, challenge their thinking when needed and help them align on a clear direction.
• Turn complexity into pragmatic solutions. You structure ambiguous business and marketing questions and translate them into realistic, actionable recommendations.
• Bring your change management expertise. You help client organisations adopt new strategies, ways of working, tools and technologies, including AI. From the case for change to sponsor and manager involvement, communication, training and adoption tracking, you make sure people actually change their behaviour and the change sticks after you leave.
• Stay on through implementation. You stay involved beyond the recommendation. You support implementation, guide teams through change or step into an interim role when the client needs it.
• Spot opportunities. You keep an eye out for new client needs and help grow our relationships together with your client partner.
• Share and coach. You strengthen THoM's expertise by sharing what you know, and you coach, challenge and support more junior colleagues.
