Role: Campaign Marketing Manager (12 Month FTC)

Location: London, United Kingdom (3 days a week from Client Canary Wharf offices)

About the role:

As a Campaign Marketing Manager, you'll be embedded within the client's UK Retail Banking Performance Marketing team — a commercially driven function responsible for customer engagement, solutions growth, and digital channel development. This is a delivery-focused role for someone who can manage multiple campaigns simultaneously, operate effectively across complex stakeholder environments, and maintain consistently high standards under pressure. You'll combine strong digital marketing expertise with a customer-first mindset, bringing clear thinking and sound judgement to everything from insight and strategy through to in-channel execution, governance, and performance reporting. The role suits someone with client-side performance marketing experience in financial services, telecoms, utilities, or another comparably regulated industry.

What you will be doing:

• Lead the end-to-end campaign delivery lifecycle — from discovery, planning, and prioritisation through to channel execution, quality assurance, and performance reporting — across paid and owned channels including video, display, social, email, radio, press, and OOH.
• Develop and execute multi-variant campaign strategies that differentiate the client from competitors through superior targeting, creative quality, and channel innovation.
• Work with the client's Marketing Centre of Excellence to ensure all communications are on-brand, product-aligned, customer-focused, and compliant with regulatory requirements and governance frameworks.
• Analyse customer, market, and performance data to surface actionable insights, translating these into effective marketing strategies and measurable campaign outcomes.
• Manage campaign budgets with a clear focus on return on investment, cost per acquisition, and commercial performance.
• Develop clear campaign roadmaps and testing frameworks in collaboration with business stakeholders, keeping projects on time and adapting effectively when priorities shift.
• Manage relationships with the client's Digital, Product, and Marketing teams, as well as external agency partners — maintaining regular stakeholder dialogue and delivering clear, evidence-based recommendations.
• Ensure the highest standards of quality assurance across all campaign materials, applying rigorous controls throughout the delivery process.
• Take ownership of risk management and governance in relation to your work, escalating issues promptly and maintaining thorough documentation.
• Report on campaign performance and testing outcomes, providing recommendations that drive continuous improvement.
• Bring proactive ideas and solutions to stakeholders, identifying opportunities to improve performance.
• Contribute to a collaborative, high-standards culture within the Performance Marketing team.
• Manage project and campaign-level budgets, including cost estimation, spend tracking, and reconciliation.
• Optimise budget allocation across channels to maximise commercial impact.
• Report on spend against forecast and surface budget risks early to relevant stakeholders.
