Senior Marketing Manager

We are working with a leading fintech innovator to find a hands-on growth marketer to work alongside their Head of Growth Marketing to build and scale the lead generation engine. You’ll bring proven experience building demand generation in fintech, payments or B2B SaaS, and use that experience to help turn the GTM strategy into a consistent, scalable source of qualified pipeline. This is a role for someone who can think strategically, execute quickly and optimise relentlessly. You’ll help build the engine – from audience and campaigns through to conversion, nurture, measurement and optimisation. You’ll also be an AI-first marketer, using AI, automation and technology every day to improve workflows, increase output and make marketing more effective.

• Help build and optimise the marketing funnel from lead to MQL to SQL to pipeline.
• Develop and optimise LinkedIn and other paid acquisition channels.
• Use data, testing and insight to continuously improve campaign performance and conversion.
• Work closely with Sales, Product and Commercial teams to ensure marketing activity generates high-quality pipeline.
• Develop and coordinate content that supports demand generation, including campaigns, landing pages, thought leadership, case studies, email and sales enablement content.
• Work with the wider Marketing team to ensure content and creative are aligned to campaign objectives and commercial priorities.
• Manage and mentor a Marketing Graduate, providing direction, support and development while managing and prioritising their workload.
• Work collaboratively with other members of the Marketing team to coordinate activity and deliver campaigns effectively.
• Use AI and automation to improve marketing processes, workflows, research, execution and output.
• Help build the processes, technology and measurement needed to create a scalable growth engine.

About you

• Bachelor’s degree in Marketing, Communications, Business, or a related discipline, or equivalent practical experience.

• Strong understanding of demand generation, paid acquisition, funnel conversion and pipeline generation.
