Job description

Are you a marketing specialist who knows how to turn data, AI and customer intent into better conversion?

We're working with a fast-growing professional services group looking for an AI Conversion & Personalisation Specialist to join its Growth & Marketing function.

This is a new, specialist role sitting at the intersection of AI, marketing automation, data, personalisation and conversion optimisation.

You'll be responsible for making sure the right prospects are identified, understood and targeted with the right message at the right time - using AI, intent data and behavioural signals to improve lead quality and ultimately drive more opportunities through the funnel.

The Role

You'll work closely with the Head of Performance, Demand Generation, AI Operations and Data teams, taking existing campaigns and programmes and making them smarter, more targeted and more conversion focused.

Your remit will include:

• Building and managing data enrichment workflows using Salesforce APIs, Companies House, Gazette and other firmographic data sources.
• Developing ICP and intent scoring models using firmographic, behavioural and third-party intent signals.
• Using AI to create and optimise personalised content, messaging and creative variants across campaigns.
• Turning real-time intent signals - such as website behaviour, content engagement and research activity - into highly relevant personalised messaging.
• Developing live audience definitions and targeting logic for paid media and outbound activity, moving away from manual list-based targeting.
• Working with Salesforce Data 360/Data Cloud and Marketing Cloud to activate enriched audiences and intent signals.
• Improving conversion performance across the funnel, from landing page and nurture through to BOFU and sales handoff.
• Designing richer conversion signals that go beyond a simple form submission and feed meaningful revenue-stage data back into advertising platforms.
• Building intent-triggered nurture and outbound journeys, ensuring prospects receive relevant follow-up based on what they are actually engaging with.
• Testing personalised vs. control messaging and using data to demonstrate the impact on engagement, lead quality and conversion.
• Working within the company's data protection, AI governance and regulatory requirements, ensuring AI-generated content is appropriately reviewed before reaching audiences.

YOU?

We're looking for someone who sits comfortably between marketing, data and technology.

You may come from a background such as:

• Marketing Automation
• Growth Marketing
• Conversion Rate Optimisation
• CRM / Lifecycle Marketing
• Performance Marketing
• Personalisation
• Marketing Technology
• AI Marketing / AI Operations
• Demand Generation

You’ll ideally have experience with several of the following:

• Salesforce Marketing Cloud / Sales Cloud
• Salesforce Data Cloud / Data 360
• Marketing automation and CRM data
• Audience segmentation and activation
• ICP development and lead scoring
• Intent data and behavioural signals
• AI-driven personalisation
• API-based data enrichment
• Paid media conversion tracking / server-side conversion data
• A/B testing and conversion optimisation
• Lead nurture and lifecycle journeys

You don't need to be a developer or data architect. What matters is that you understand how marketing data, AI and technology can be applied to improve targeting and conversion - and you're comfortable getting hands‑on with the tools.

Why This Role?

This is an opportunity to take ownership of a genuinely modern marketing discipline.

You'll be joining an organisation investing heavily in AI, data and marketing technology, with the opportunity to shape how personalisation and intent-led marketing are delivered across the wider group.

Rather than simply running campaigns, you'll be responsible for answering questions such as:

Who should we target?
Why are they likely to buy?
What are they interested in right now?
What should we say to them?
And how do we prove it converted?

If you're passionate about using AI and data to make marketing more intelligent, personalised and commercially effective, we'd like to hear from you.
