Interim Head of Growth Marketing

Attest
London

Role Overview

At Attest, we're revolutionising how global brands like Unilever, Netflix, and Bloomberg turn consumer insights into competitive advantage. Positioned at the intersection of evolving technology and rapidly changing consumer behaviour, we're building the next generation of consumer intelligence that helps brands understand their customers better than ever before.

We’re seeking an Interim Head of Growth Marketing to start at the end of June or early July for a 12 month contract to drive our growth strategy focussing on UK and US markets.

This senior strategic and implementation role involves running cross-functional projects, developing innovative AI-enhanced growth plans, and building scalable customer acquisition programs. You'll have autonomy to drive success through cutting-edge marketing technology.

The Logistics

We embrace a flexible hybrid work model. While we don't mandate specific office days, we ask Attesters to work on-site 2 days per week. This approach allows us to collaborate in person, while ensuring enough time remotely for deep, focussed work.

The salary band for this role is £95,000 - £115,000.

Please note this role is offered on fixed term basis for 12 months. Ideally we would be looking for the successful candidate to start mid-June or early July. A completion bonus will also be offered to candidates who reach the end of the contract.
