About the Team:

As Website Conversion Rate Optimisation Senior Manager, you will own the strategy and delivery of conversion rate optimisation across our corporate website, driving measurable improvements in visitor-to-pipeline performance. Reporting to the Senior Director of Digital Marketing, you will work in close partnership with our Digital Marketing Director, Web Development Specialist, and external agencies to build and execute a data-led optimisation programme that turns website traffic into qualified pipeline.

This is a hands-on role that requires equal comfort with analytical rigour and creative problem-solving — you will be expected to identify opportunities, build the business case, and see initiatives through from hypothesis to result.

Responsibilities:

Conversion Rate Optimization (CRO)

• Own and manage a prioritized CRO roadmap, aligned to pipeline generation goals and broader business objectives

• Take full ownership of optimization initiatives from initial opportunity identification through to live implementation and post-test analysis — building the business case, securing stakeholder alignment, and driving delivery in partnership with UX, content, and development teams

• Analyze customer journeys to identify friction points, drop-off patterns and conversion opportunities across the website

• Design, deploy and evaluate A/B and multivariate experiments, translating results into clear recommendations and next actions

• Manage relationships with external CRO agencies and vendors, ensuring delivery is on brief, on time and measurable

• Monitor developments in AI and agentic tooling across the marketing landscape, proactively identifying where new capabilities can be applied to streamline web delivery, enhance experimentation, and drive better conversion outcomes

SEO & Answer Engine Optimization (AEO)

• In conjunction with the SEO/AEO agency, monitor organic search performance, identifying opportunities to improve indexing, ranking and visibility for high-intent B2B audiences

• Collaborate with the Digital Marketing Director to ensure website content is structured and optimized for both traditional search engines and AI-powered answer engines (AEO)

• Stay current with evolving search behaviors, including LLM-driven discovery, and propose new adaptations to the optimization strategy

Performance & Reporting

• In partnership with the Marketing Operations Performance team, define and track the KPIs that connect website performance to pipeline contribution, reporting regularly to the Senior Director

• Contribute to building a culture of evidence-based decision-making, using quantitative and qualitative data to prioritize and justify activity

• Monitor page-level performance trends and proactively surface risks and opportunities

Cross-functional Collaboration

• Partner with UX, Development, Growth Marketing and Brand Marketing teams to translate data-driven insights into clearly scoped, actionable briefs — consulting on priorities and next steps, then driving delivery through to completion

• Work closely with the Digital Marketing Director to ensure that experimentation proposals and website updates adhere to brand guidelines and are compatible with current systems and tooling before progressing to delivery

Qualifications:

• 7-9+ years of marketing experience

• At least 2 years' experience running CRO programs in a B2B environment; SaaS, healthcare, life sciences, or regulated industries preferred

• Experience using AI tools as part of daily workflow, Gemini and Notebook LM preferred

• Experience with Optimizely platform preferred

• Comfortable working with data to form hypotheses, interpret results and make confident recommendations — even when the picture is incomplete

• A clear understanding of how website performance connects to business outcomes, with the ability to prioritize work that moves the metrics that matter

• Able to present findings and proposals clearly to both technical and non-technical stakeholders, and to build buy-in across teams without direct authority

• Skilled at managing a roadmap of concurrent initiatives, balancing speed with rigor and keeping multiple partners aligned

• A natural team player who builds strong working relationships with internal colleagues and external agencies alike, and understands how to get the best from each

• Proactive in keeping up with the evolving digital landscape — particularly around AI-driven search and changing B2B buyer behavior online
