Job Description :

Senior UX Strategist

Hello, we are Ledger Bennett, the integrated B2B agency within Havas Group.

We're uniquely positioned at the intersection of entrepreneurial spirit and global scale. Since 1985, we've been obsessed with a singular mission: transforming one-time buyers into Forever Customers, creating long-term value rather than just short-term impact.

We deliver this through the powerful fusion of data, creativity, and media. 

Now, as part of the Havas family, the opportunities have never been bigger. Here, you'll work alongside talent across EMEA, APAC, and North America, partnering with clients like GE, Microsoft and LinkedIn to deliver radical relevance and intelligent customer experiences that drive real growth. 

With 40+ years of B2B expertise and the backing of a global network, Ledger Bennett offers you the rare chance to shape the future of B2B marketing while building a career with no ceiling – just endless opportunity.

We’re looking for a Lead UX Strategist to define and elevate user experience across websites and digital campaigns. This is a client-facing role focused on usability, information architecture, and user validation through testing. You’ll lead the definition of experience frameworks, from structure and flows to wireframes, whilst partnering closely with UX/UI designers who bring these experiences to life visually.

Crucially, this role goes beyond project delivery. You’ll play a key part in shaping and growing the agency’s UX offering, with the opportunity to establish processes, influence strategy, and build a UX team over time.
