We’ve gone from zero to ten, now we’re looking to go from ten to one hundred!

We're building out the marketing function from the ground up, and this is a rare chance to be the second marketing hire and help shape how the team operates. You'll work closely with the Head of Marketing, taking ownership of the day-to-day execution that drives growth - from events and digital marketing to content and website support - while the HoM focuses on strategy, product marketing, ABM, partnerships, and broader commercial initiatives.

It’s a lean team and so this role suits someone who enjoys experimenting to drive growth and who wants ownership across the funnel rather than depth in a single specialism.

This is not a coordinator role. We're looking for someone who can take a brief and run with it, manage competing priorities independently, and bring structure and ideas to our marketing operations without needing close oversight. You'll have real ownership over your areas and the autonomy to make decisions, with support and direction from the HoM.

• End-to-end planning and delivery of webinars, conferences, sponsor ships, and in-person events, including logistics, vendor management, and on-site support where needed
• Manage event budgets, timelines, and post-event reporting (leads, engagement, ROI)
• Coordinate speaker and sales involvement, and ensure smooth follow-up into Hub Spot and the sales pipeline

• Act as primary Hub Spot administrator: manage workflows, lists, email campaigns, lead scoring, and data hygiene
• Build and send marketing emails and nurture sequences
• Support paid campaigns on Linked In and Google Ads (campaign set-up, monitoring, basic optimisation, reporting), working alongside agency partners managed by the HoM
• Maintain dashboards and reporting on core digital marketing metrics

• Partner with internal subject-matter experts to source insight and turn it into content (articles, Linked In posts, case studies, newsletters), using AI tools to accelerate production rather than writing everything from scratch
• Own the organic social media calendar and posting, primarily Linked In
• Repurpose long-form content (webinars, whitepapers, reports) into multi-channel assets
• Maintain brand and tone consistency across all marketing output

• Make routine website updates (new pages, blog posts, landing pages, minor content/CMS changes)
• Flag larger website or UX projects to the HoM and liaise with developers/agencies as needed

• 5–6 years' B2B marketing experience, ideally in SaaS, fintech, or financial/professional services
• Hands-on Hub Spot experience, ideally including admin‑level configuration (workflows, lists, reporting)
• A genuine generalist: comfortable moving between events, content, paid social support, and website tasks in the same week
• Working knowledge of Linked In Ads and Google Ads (you don't need to be a paid media specialist, but you should be confident enough to manage day‑to‑day campaign tasks alongside an agency)
• Strong project…
