Operating across five regions, we power over 200 market‑leading events, publications and brands across Business Technologies, Healthcare, Learning, HR & Education, and Future Transport & Infrastructure.

But what truly sets us apart is our people.

Our teams are diverse, driven, and united by a shared commitment to excellence. Rooted in our core values of ownership, empathy, teamwork, integrity, and determination, we empower every employee to grow, shape their own path and make a meaningful impact.

WHO WE ARE LOOKING FOR:

We're looking for a digitally curious, detail‑oriented Marketing CRM Assistant to support our central CRM team in delivering high‑quality campaign support, data integrity, and platform management across Hub Spot and Salesforce.

This is an ideal role for an early‑career professional seeking practical CRM experience in a fast‑paced, international events business. You'll get hands‑on exposure to marketing automation (Hub Spot), sales CRM processes (Salesforce), and the crucial work of keeping our data clean, accurate, and accessible for teams across the UK, Europe, Asia, and the US.

If you're someone who loves systems, enjoys solving problems, and wants to build a career in CRM, marketing operations, or data, this could be the perfect role for you.

  • Act as 1st line CRM support for Hub Spot and Salesforce users, responding to day‑to‑day queries, troubleshooting common issues, and ensuring timely resolution
  • Triage and categorise CRM‑related issues, resolving where possible and escalating more complex 2nd and 3rd line support matters to the Marketing CRM Manager, Data team, or external partners
  • Be a day‑to‑day contact for CRM queries, supporting internal teams with Hub Spot tasks including list building, contact enrichment, campaign setup checks, and access support
Data Management & Campaign Support:
  • Support basic Salesforce tasks such as data checks, field validation, record updates, and assist with cross‑platform data consistency between Hub Spot and Salesforce
  • Build and manage campaign lists, segments, and filters to support accurate targeting across all portfolios
  • Assist with importing, deduplicating, tagging and enriching data for shows and regions, ensuring consistent hygiene across systems
Onboarding & User Support:
  • Support onboarding processes for new CRM users or acquired events, including permission set‑up and documentation
  • Help create internal resources and process guides for marketing teams using Hub Spot and basic Salesforce processes where relevant
Data Hygiene & Quality Control:
  • Conduct weekly hygiene audits to identify and elevate issues with duplicates, inactive properties, field inconsistencies, and broken workflows
  • Collaborate with the Data team to maintain GDPR compliance and field standardisation across both platforms
  • Assist with audits and setup for new event editions, including form logic, workflow tagging, list generation, and CRM alignment
Reporting & Insights:
  • Assist in reporting and insight collection by pulling base‑level reports from Hub Spot and Salesforce to support campaign and pipeline reviews
  • Support the development and QA of automated workflows
