Lead Digital Engineer Department: Tech & Product Employment Type: Full Time Location: Trimble Offices, Morley Description About the team: At Vintage Cash Cow, technology is how we scale impact. Every customer journey, from sending in pre loved items to getting paid, is powered by the systems we design, the products we build, and the data we unlock. Our Technology & Data team is at the heart of this transformation driving greenfield product development, experimenting with fresh ideas, and bringing innovative solutions to life. We're building modern, scalable, and customer focused platforms that set the standard for the re commerce industry. This is a team where curiosity meets craft: blending creativity, technical excellence, and a product mindset to deliver experiences that feel simple, rewarding, and future proof. About the role: We're looking for a Lead Digital Engineer to own and evolve our digital customer experience-from the technology that powers it to the data that optimises it. This hybrid role sits at the intersection of front end engineering, growth engineering, and marketing technology, and it's pivotal to how we acquire, convert, and delight customers online. Our current front end is built on Webflow, and we need someone who can evaluate the landscape, define a technology roadmap, and lead the charge in building modern, high performance digital experiences. But this isn't just about code-you'll also understand user tracking, analytics implementation, SEO, and conversion optimisation. You'll work together with our teams to ensure our digital presence is engineered for growth. This role is part strategist, part hands on engineer, part growth hacker. You'll run experiments, develop customer experiences, implement robust tracking, and potentially develop standalone applications. You'll make key architectural decisions, champion engineering excellence, and mentor developers to deliver their best work. If you're energised by the idea of bridging the gap between engineering and marketing, love using data to drive decisions, and want to shape digital experiences from the ground up-you'll thrive here. This role may require you to work from the Leeds offices from time to time, travel to our European location and other international locations as we scale, and provide out of hours support when needed. Getting Started Immerse yourself in our current digital ecosystem: Webflow setup, customer journeys, tracking implementation, and analytics. Audit our existing front end technology, SEO foundations, and marketing technology stack-identify quick wins and strategic opportunities. Build relationships with engineering, marketing, data, and product teams to understand priorities and ways of working. Contribute to the research and lead the evaluation of front end frameworks, tools, and approaches suited to our growth ambitions. Begin building team capability through structured mentoring, code reviews, and knowledge sharing sessions.

Establish robust tracking and analytics infrastructure that powers data driven decision making across the business. Develop rapid experiments and A/B tests to validate hypotheses and optimise conversion funnels. Partner with Marketing and Product on campaign experiences, and performance marketing requirements. Own technical SEO-improving site structure, Core Web Vitals, and search visibility. Build full customer facing experiences and potentially standalone applications. Driving Excellence Own digital delivery end to end: from concept and experimentation, through architecture and execution, to launch and optimisation. Champion a culture of experimentation, curiosity, and continuous learning. Develop and mentor developers at all levels, building a high performing team with strong digital and growth engineering skills. Be the bridge between Engineering, Product, Marketing, and Data-translating business goals into technical solutions. Keep an eye on emerging tech, propose and trial new tools that could transform how we work. Key Responsibilities Evaluate and define our digital technology strategy, evolving beyond Webflow where appropriate. Deliver high quality digital experiences using modern front end frameworks, growth engineering practices, and robust analytics.

Own the front end integration layer-consuming APIs, handling data flows, and ensuring robust error handling. Collaborate on integration requirements for third party platforms (e.g., payment providers, CRM, marketing automation, analytics services). Ensure tracking and analytics implementations are correctly integrated with backend event pipelines where required. Growth Engineering & Experimentation Design and run A/B tests and experiments to optimise conversion rates across the customer journey. Build and optimise landing pages, sign up flows, and conversion funnels to support performance marketing. Implement experimentation infrastructure (e.g., feature flags, A/B testing platforms) to enable rapid iteration. Work with product and marketing to prioritise growth experiments based on potential impact and effort. Analytics & Marketing Technology Implement and maintain robust user tracking, event capture, and tag management (e.g., Google Tag Manager, Segment). Integrate analytics platforms (e.g., Google Analytics 4, Mixpanel, Amplitude) to capture meaningful user behaviour data. Work closely with data and marketing teams to define tracking requirements and ensure data quality. Ensure pixel implementation and conversion tracking for paid media channels (Google Ads, Meta, etc.).
