UX Designer (Conversion Rate Optimisation)

As a UX Designer, you won't just be making things look "nice" - you'll be making them work better. You will sit at the intersection of psychology, data, and design. Your mission is to identify friction points in the Ocado customer journey and design elegant, high-performing solutions that drive measurable growth.

This role sits in the Conversion Rate Optimisation (CRO) team using data and experimentation to make our website easier to use and more effective at turning visitors into customers. We bridge the gap between marketing, merchandising and design by testing new ideas and using real human behaviour to guide our decisions. Instead of guessing, we focus on continuous improvement to make every step of the online shopping journey smoother and more successful.

What you'll do

• Data-Driven Design: Transform requests based on user data, heatmaps, and A/B test results into intuitive wireframes and high-fidelity prototypes.
• Hypothesis Building: Partner with Product Leads and Data Analysts to run workshops and form testable hypotheses
• User Research: Conduct lean usability testing and synthesise feedback to ensure our "experiments" are grounded in real human behaviour.
• Iteration & Testing: Rapidly iterate on designs based on live experiment data. You understand that a "failed" test is just a data point for a better design.
• Cross-Functional Collaboration: Work closely with other teams across the business to maintain brand consistency and work towards joined up business goals.

Do you have experience in UX?, * Experience: Proven experience in UX design, preferably within e-commerce or a high-transaction digital environment.

• The "CRO Mindset": You are obsessed with performance metrics. You know that a 1% lift in conversion at Ocado's scale translates to massive impact.
• Tools of the Trade: Mastery of Figma is essential. Familiarity with experimentation tools (like Optimizely, Usertesting, or Contentsquare) is a huge plus.
• Systems Thinking: The ability to design for a complex ecosystem where a change in the "Basket" affects the "Delivery Slot" picker.
• Customer focused: You are considerate of how experiences impact customers and have knowledge of accessibility guidelines and best practices
• Communication: You can articulate the why behind a design choice to stakeholders using both qualitative stories and quantitative data.

Desirable

• Experience with grocery e-commerce or complex "recurring" subscription models.
• A basic understanding of HTML/CSS to better collaborate with front-end engineers.
• Curiosity for how AI can be used to enhance your role and improve ways of working.
• A passion for food, logistics, or sustainable tech!
