Senior Growth Marketing Manager

About the role

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.

Responsibilities

• Events Management (~25-30%)
• End-to-end planning and delivery of webinars, conferences, sponsorships, 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 HubSpot and the sales pipeline
• Digital Marketing & HubSpot Admin (~25%)
• Act as primary HubSpot administrator: manage workflows, lists, email campaigns, lead scoring, and data hygiene
• Build and send marketing emails and nurture sequences
• Support paid campaigns on LinkedIn 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
• Content & Social (~40-50%)
• Partner with internal subject-matter experts to source insight and turn it into content (articles, LinkedIn 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 LinkedIn
• Repurpose long-form content (webinars, whitepapers, reports) into multi-channel assets
• Maintain brand and tone consistency across all marketing output
• Website Updates
• 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
• What You Bring
• 5-6 years' B2B marketing experience, ideally in SaaS, fintech, or financial/professional services
• Hands-on HubSpot 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 LinkedIn 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 management instincts: you organise your own workload, set priorities, and proactively flag risks rather than waiting to be told what's next
• Experience using AI tools (e.g. ChatGPT, Claude)
• Excellent written English and an eye for clear, professional B2B content
• Mindset
• A self-starter: as the first marketing hire, you'll need to build processes as you go, not rely on existing ones
• Curious, experimental, and not afraid to challenge assumptions
• Energised by building, iterating and improving rather than maintaining the status quo.

Requirements

• Experience marketing into financial services, asset management, or private capital markets
• Familiarity with ABM concepts and working alongside a sales team
• Basic design skills (Canva, Adobe Express) for quick-turnaround social or event assets
