CRO and Experience Optimisation Manager

Job Title: CRO and Experience Optimisation Manager
Experience: 3+ Years
Location: Hybrid – London (1 day per week) / Remote
Type: Contract-to-Hire
Salary: Up to £50,000

Role Overview

We are a London-based MarTech and experience optimisation agency working with global brands. We are looking for a CRO Manager to lead A/B testing, personalisation, and digital experience optimisation across both client projects and internal initiatives.

In this role, you’ll have dual focus:

1. Strategic enablement – helping define and evolve the personalisation and optimisation strategy, ensuring it is scalable, governed, and future-ready.
2. Hands-on delivery – executing the end-to-end experimentation cycle, from ideation through to insights, while building repeatable frameworks for success.

Reporting directly into the CMO, you will also play a key role in shaping and growing our experience optimisation practice.

Strategic Enablement

• Define and evolve personalisation and CRO strategies to support long-term client and business goals, enabling best-in-class customer experiences.
• Act as Product Owner for testing and personalisation capabilities, ensuring roadmaps support scalability, governance, and innovation.
• Collaborate with CMS product owners to enable seamless internal workflows that accelerate delivery and reduce operational overhead.
• Align personalisation and CRO initiatives with broader MarTech, data, and content strategies.

Capability Development

• Lead personalisation and optimisation workstreams during rollout of new journeys and capabilities across web and app platforms.
• Drive integration of tools such as Adobe Target and CMS platforms (e.g. Contentful, Optimizely CMS) to support dynamic content delivery and behavioural targeting.
• Create and maintain documentation to support onboarding, knowledge sharing, and operational consistency across client and internal teams.
• Mentor junior team members, fostering skills and ensuring continuity of best practices.

End-to-End CRO Execution

• Lead the full CRO and personalisation cycle: ideation > hypothesis generation > design & wireframing > build > QA > launch > analysis & insights.
• Develop and maintain experimentation, personalisation, and optimisation frameworks that can scale across multiple clients and projects.
• Collaborate with product owners, designers, marketers, and developers to generate and prioritise test ideas aligned with strategic goals.
• Build, deploy, troubleshoot, and optimise experiments using Adobe Target, Optimizely or similar platforms.
• Analyse test results using GA4, Adobe Analytics, and other analytics tools, providing clear, actionable insights to stakeholders.
• Establish governance and reporting frameworks to ensure accurate tracking, tagging, and measurement.

Cross-Functional Collaboration

• Partner with product, engineering, analytics, and content teams to embed personalisation into the digital delivery lifecycle.
• Collaborate with clients, external vendors and internal stakeholders to deliver scalable, compliant, high-impact solutions.
• Represent personalisation and CRO strategy in forums, workshops, and planning sessions.

Tools & Skills

• Essential: Proven experience with CRO methodologies and tools like Adobe Target, Optimizely, GA4 and Adobe Analytics.
• Technical proficiency in front-end web technologies (HTML, CSS, JavaScript) for implementing and troubleshooting experiments.
• Familiarity with CMS platforms, particularly headless CMS (e.g. Contentful, Optimizely CMS).
• Experience with session replay and behaviour analytics tools (HotJar, Decibel, FullStory) is highly regarded.
• Familiarity with GTM and tag management is also highly regarded but not essential.
• Strong analytical skills and ability to translate data into actionable insights.
• Excellent communication skills and experience working in cross-functional, multi-client or multi-market environments.

Qualifications

• 3+ years’ experience in CRO, digital optimisation, or personalisation roles, ideally within an agency or client-service environment.
• Demonstrated success in delivering both strategic enablement and hands-on optimisation.
• Proven track record of running successful A/B tests, personalisation campaigns, and building scalable experimentation frameworks.
• Experience working on large-scale or enterprise-level digital transformation programmes is a plus.
• Comfortable managing multiple projects for high-profile clients while contributing to the growth of an agency practice.

What We Offer

• The opportunity to shape and grow our Experience Optimisation practice within a fast-moving MarTech agency.
• Work with global brands across multiple sectors, delivering measurable impact at scale.
• A collaborative, insight-driven culture where your ideas directly influence client strategy.
• Hybrid working: 1 day per week in our London office, with the flexibility to work remotely the rest of the time.
• Ongoing training and development, including access to AI, automation, and experimentation frameworks to stay ahead in the field.
• 25 days vacations and 1 additional day off on birthdays
