Optimisation Manager in London

WPP Enterprise Solutions designs, builds, and operates the growth systems that competitive businesses rely on. In a world where AI is reshaping how companies drive growth, we lead clients in business transformation and marketing modernization, connecting strategy directly to execution. Our 12,000 experts in engineering and platforms, commerce, consulting, content transformation, CRM, and CX work within a unified global operating unit across 40+ markets.

We are seeking a highly motivated and data-driven Optimisation Manager to execute and run daily, high-velocity site optimisation and continuous improvement initiatives. Reporting directly to the Optimisation Lead, you will be the driving force behind the day-to-day execution of our Rapid Iteration & Optimisation (RIO) framework. You will sit at the intersection of data, technology, and execution—translating tactical roadmaps into live, performance-enhancing site updates. Working hand-in-hand with the Paid Media, CX, and Development teams, you will turn real-time trading insights into immediate, measurable business growth for our global clients.

What You’ll Be Doing

• Execution of Site Optimisation & RIO Roadmap
• Daily Campaign Management: Own the hands-on execution and QA of the weekly site optimisation roadmap, ensuring rapid deployment and zero-defect delivery of experiments and content updates.
• A/B Testing & Personalisation: Build, launch, and monitor A/B tests, multivariate tests, and personalisation campaigns designed to immediately boost real-time trading performance and conversion rates (CRO).
• Cross-Functional Coordination: Collaborate daily with copywriters, designers, developers, and the Paid Media team to coordinate asset production and ensure rapid execution of updates.
• Performance Analysis & Reporting
• Real-Time Monitoring: Keep a finger on the pulse of live campaign performance, monitoring real-time analytics suites to identify sudden performance drops, bugs, or immediate conversion opportunities.
• Insights Translation: Synthesize complex data from test results into actionable recommendations. Help the Optimisation Lead compile weekly performance reports demonstrating trading uplift and ROI.
• Audience Segmentation: Utilise Customer Data Platforms (CDPs) and web analytics tools to build, manage, and optimize dynamic audience segments for targeted messaging.
• Technology & Platform Operations
• Platform Operations: Act as the super-user and administrator for our stack of site optimization, analytics, and content management platforms.
• Data Quality & Tagging: Ensure tracking codes, analytics tags, and event-tracking parameters are correctly implemented on all optimized pages to safeguard data integrity.

What We Want From You

We are looking for an execution-focused digital specialist who is highly organized, agile, and obsessed with conversion rate optimization (CRO) and real-time performance.

Technical Skills & Experience

• Site Optimisation Platforms: Proven hands-on experience using optimization and A/B testing software (e.g., Optimizely, VWO, Adobe Target, Siteimprove, or similar meta-optimisation tools).
• Analytics Suites: Proficient in setting up custom reports, segments, and event tracking in web analytics suites (e.g., Google Analytics 4, Adobe Analytics, Amplitude).
• Content Management Systems (CMS): Experience editing, publishing, and running personalisation initiatives within enterprise CMS platforms (e.g., Adobe Experience Manager, Sitecore, or Shopify).
• Customer Data Platforms (CDPs): Familiarity with how CDPs (e.g., Segment, Tealium) ingest and activate audience data for real-time personalisation is highly desirable.
• Basic Frontend Knowledge: A foundational understanding of HTML, CSS, and JavaScript (specifically how they affect browser rendering and A/B test implementation) is a significant plus.

Execution & Mindset

• High Velocity: A "rapid delivery" mindset. You thrive in fast-paced environments and love seeing your work go live to drive immediate commercial impact.
• Agile Competency: Comfort working in agile sprint cycles, managing weekly backlogs, and juggling multiple fast-turnaround tasks simultaneously.
• Analytical Thinking: Naturally curious and highly analytical. You don’t just look at data; you look for the "why" behind user behaviour.
• Collaborative Communicator: Excellent interpersonal skills with the ability to bridge the gap between creative, technical, and commercial stakeholders.
