Lead Front End Engineer

Department: Information Technology

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 Front End Engineer to own and evolve our digital customer experience—from the technology that powers it to the data that optimises it. This is a hybrid role that 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 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 work with our internal teams to understand user tracking and implement analytics tools.

You'll develop experiments, build 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.

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 and marketing enablers.

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.

Establishing Your Impact…

Define and implement our digital technology strategy—recommending modern frameworks, tooling, and architecture.

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.

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

Key Goals & Objectives:

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.

Build digital infrastructure that supports performance marketing—optimised landing pages, conversion tracking, and campaign agility.

Ensure comprehensive user tracking and analytics are embedded across all digital touchpoints, enabling data-driven decisions.

Own and improve technical SEO, driving organic visibility and site performance.

Champion a product and growth mindset, ensuring everything built solves real customer and business problems.

Build a high-performing team by mentoring developers, sharing knowledge, and raising technical standards.

Continuously improve development practices, leveraging modern tooling, testing frameworks, and automation.

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.).

SEO & Performance Marketing

Own technical SEO: site structure, crawlability, schema markup, meta tags, and Core Web Vitals.

Manage Cloudflare for performance/CDN.

Ensure front-end architecture supports SEO best practices.
