About the role

At Clarion, our people are at the absolute heart of what we do.  We’re proud that our core values of PASSION, CARE, IMAGINATION, and TRUST define the way we carry out our work across all of our teams.


If you share our values and want to be a part of a successful, dynamic, and creative global business then we want to hear from you.  

The Opportunity:  

DSEI is one of the world’s leading defence and security exhibitions, bringing together governments, armed forces and industry from around the globe. As Campaign Marketing Manager for our Defence portfolio, you’ll own the audience campaigns that fill DSEI UK, DSEI Japan and DSEI Germany, and help grow DSEI Gateway, our defence news brand.

This is a senior, hands-on role for an events marketer who has done this at scale. You’ll own campaign strategy and delivery across multi-million-pound event products, be accountable for audience quality, registrations and conversion, and lead a team of two: a Senior Marketing Executive and a newly appointed Marketing Executive.

You’ll report to the Head of Marketing, who will set the direction and then trust you to run with it. Not every step will be mapped out for you, and that’s the point. We want someone who sees what needs doing, gets on with it, and tells us when there’s a better way.

Who we’re looking for:

We’re looking for an experienced events or exhibitions marketer who has run campaigns for large-scale events and can show the results. You will have either:

  • Held marketing responsibility for event products generating up to £7 million in revenue, or

  • Run high-volume audience campaigns delivering 20,000+ registrations for large-scale events or exhibitions.

You’re a natural optimiser who never considers a campaign finished: you test, read the data and improve. You pair that with real creativity and outstanding copywriting, so your campaigns both perform and stand out. You’re highly adaptable, comfortable working without a detailed brief, and confident challenging the way things have always been done when you can see a better approach.

This role is likely to suit someone with at least six years’ marketing experience, a significant part of it in events, exhibitions or conferences, and some experience of managing people. Defence sector experience isn’t essential; we’ll help you learn the market. Large-scale events experience is.

Key Responsibilities:  

Campaign Strategy & Ownership

  • Own the end-to-end audience marketing strategy for DSEI UK, Japan and Germany, from campaign launch to show day, driving registrations, attendance and revenue from the right audiences.

  • Set campaign targets, forecasts and budgets with the Head of Marketing, and be accountable for delivering them.

  • Build and deliver the plan to grow DSEI Gateway’s audience and engagement.

  • Present plans, progress and recommendations clearly to senior stakeholders across the event, sales and content teams.

Optimisation & Performance

  • Continuously test, measure and refine across channels (audiences, offers, subject lines, landing pages, paid media) to improve conversion and audience quality.

  • Own marketing reporting: weekly KPI and registration tracking, forecasting against target, and post-event reports with clear insight and actions.

  • Manage the product marketing budgets and make sure every pound is working hard.

  • Spot early when something isn’t working and change course quickly, without waiting to be told.

Creative & Copy

  • Write and edit compelling, conversion-focused copy across email, web, paid social, print and on-site materials, and set the standard for copy across the team.

  • Bring fresh creative ideas and campaign concepts that cut through with a senior, specialist defence audience.

  • Make sure all output is on brand and tailored to our key audience personas.

Leadership & Ways of Working

  • Line manage and develop a Senior Marketing Executive and a Marketing Executive, including onboarding and coaching a new starter.

  • Brief and manage agencies, freelancers and colleagues across the wider marketing and content teams.

  • Challenge existing processes and bring ideas from outside the business on how we can do things better.

Knowledge, Skills & Behaviours:

Essential

  • Substantial experience marketing large-scale events, exhibitions or conferences, ideally B2B.

  • A track record of either revenue responsibility for event products of up to £7m, or driving 20,000+ registrations for large-scale events. Be ready to talk us through the numbers.

  • A proven optimiser, with clear examples of testing, analysing data and using it to improve results.

  • An excellent direct-response copywriter and editor, with a portfolio that shows it.

  • A creative thinker who brings new ideas rather than repeating last year’s campaign.

  • Strong multichannel knowledge across email and marketing automation, paid media, social, landing pages and CRM, with real depth in two or three channels.

  • Experience managing people, as well as agencies and freelancers.

  • A self-starter who is comfortable with ambiguity and can prioritise across several events running in overlapping cycles.

  • A confident communicator who can challenge constructively and influence senior stakeholders.

Nice to have

  • Experience in defence, security, government or another specialist B2B sector.

  • Experience marketing international events, particularly in Europe or Asia-Pacific.
