UX Optimisation Specialist

📍 Job Overview

Job Title: UX Optimisation Specialist

Company: Nationwide

Location: United Kingdom

Job Type: Temporary (6-month secondment)

Category: Digital Optimisation & User Experience

Date Posted: 2026-06-09T16:38:46

Experience Level: Mid-Level (2-5 years)

Remote Status: Hybrid (1 day/month in Swindon office)

🚀 Role Summary

• Drive the establishment and embedding of a robust optimisation capability within digital origination journeys.

• Define and implement a comprehensive experimentation framework to foster continuous improvement and data-driven decision-making.

• Lead A/B testing and behavioural analysis initiatives to identify and resolve customer friction points, enhancing user experience and conversion rates.

• Integrate testing tools and processes into digital customer journeys, building a prioritized backlog of experiments.

• Ensure consistent governance and reporting for all optimisation activities, laying the groundwork for a sustainable test-and-learn culture.

📝 Enhancement Note: This role is a 6-month secondment, indicating a project-based need to build and transfer knowledge, rather than a permanent hire. The focus on "origination journeys" suggests a critical touchpoint in the customer lifecycle, likely involving financial products or services. The emphasis on establishing a capability and embedding processes points to a strategic, foundational role, requiring strong change management and stakeholder engagement skills.

📈 Primary Responsibilities

• Design, implement, and refine an effective experimentation framework for digital origination journeys.

• Conduct in-depth behavioural analysis and A/B testing to uncover opportunities for UX enhancement and conversion rate optimisation (CRO).

• Collaborate closely with the experience design team to translate insights into actionable improvements.

• Develop and manage a prioritized backlog of optimisation experiments, aligning with business objectives.

• Establish and enforce governance protocols for testing, ensuring data integrity and compliance.

• Create comprehensive documentation, training materials, and best practices to support a self-sustaining test-and-learn culture.

• Report on experiment performance, key learnings, and overall optimisation impact to stakeholders.

• Embed testing tools and processes into the daily workflows of relevant teams.

• Facilitate knowledge transfer and capability building for ongoing optimisation efforts post-secondment.

• Identify and leverage data-driven insights to reduce customer friction and improve digital outcomes.

📝 Enhancement Note: The responsibilities clearly indicate a hands-on role focused on building out a new function. The emphasis on "embedding" and "foundations" suggests a need for someone who can not only execute but also strategize and implement sustainable processes and cultural shifts within the organization. This also implies a need for strong communication and training skills to ensure buy-in and adoption from various teams.

🎓 Skills & Qualifications

Education: While no specific degree is listed, a background in a quantitative field such as Statistics, Data Science, Computer Science, Psychology (with a focus on human-computer interaction), or a related discipline would be beneficial.

Experience: 2-5 years of experience in User Experience (UX) optimisation, Conversion Rate Optimisation (CRO), or a closely related digital analytics and experimentation role.

Required Skills:

• Proven experience in designing and executing A/B tests and multivariate tests.

• Strong understanding of behavioural analysis techniques and tools.

• Proficiency in developing and implementing experimentation frameworks.

• Ability to translate data-driven insights into actionable UX improvements.

• Experience with digital journey mapping and identifying friction points.

• Demonstrated ability to build a prioritized backlog of experiments.

• Solid understanding of governance and reporting for optimisation initiatives.

• Excellent stakeholder collaboration and communication skills.

• Experience in embedding new tools and processes within digital teams.

• Familiarity with building a "test-and-learn" culture. Preferred Skills:

• Experience with specific A/B testing platforms (e.g., Optimizely, Adobe Target, VWO).

• Knowledge of web analytics tools (e.g., Google Analytics, Adobe Analytics).

• Familiarity with UX research methodologies beyond A/B testing (e.g., user interviews, usability testing).

• Experience in the financial services industry.

• Understanding of digital origination processes.

📝 Enhancement Note: The experience level suggests a specialist who can operate independently but may not yet be at a senior management level. The "secondment" nature implies the company is looking for someone to bring immediate expertise and establish best practices, making practical, hands-on experience paramount. "Origination journeys" in a financial context (Nationwide) hints at a need to understand complex user flows related to account opening, loan applications, or similar critical processes.

📊 Process & Systems Portfolio Requirements

Portfolio Essentials:

• Demonstrable case studies showcasing successful A/B tests or optimisation initiatives, detailing the hypothesis, methodology, results, and impact on key metrics (e.g., conversion rates, task completion).

• Examples of experimentation frameworks or process documentation developed.

• Evidence of analysing user behaviour data to identify optimisation opportunities.

• Documentation of how user friction was identified and reduced.

• Examples of reporting dashboards or summaries that effectively communicate optimisation performance. Process Documentation:

• Ability to document end-to-end optimisation processes, from hypothesis generation to analysis and reporting.

• Experience in creating standard operating procedures (SOPs) for A/B testing and experimentation.

• Proficiency in outlining governance structures for A/B testing to ensure quality and consistency.

• Skills in developing training materials for teams on optimisation tools and methodologies.

📝 Enhancement Note: Given this is a role focused on establishing a capability, the portfolio should highlight the candidate's ability to not just execute but also to build and document processes. This is crucial for a secondment role where knowledge transfer is key. The emphasis on "embedding" and "foundations" means showcasing experience in creating repeatable, scalable optimisation workflows is essential.
