FULL DESCRIPTION

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.

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. - 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.

Key Responsibilities:

Front End & Engineering - Evaluate our current Webflow-based front end and define a technology roadmap for the future. - Lead the design, architecture, and delivery of modern front-end solutions using appropriate frameworks (e.g., React, Next.js, Vue, or similar). - Strong foundation in HTML, CSS/SCSS, and responsive design principles. - Experience with component libraries, design systems, and front-end architecture patterns. - Establish and enforce coding standards, ensuring the team delivers clean, testable, maintainable code.

Integrations & API - Work closely with backend engineers (.NET) to design and implement integrations with internal services and APIs. - 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.).

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. - Optimise page speed, Lighthouse scores, and overall web performance. - Collaborate with content and Marketing teams to ensure SEO requirements are built into the development process.

Team Leadership & Growth - Mentor and coach developers at all levels, fostering a learning culture. - Contribute to code reviews, pair-programming, and technical discussions. - Contribute to and develop team and personal development objectives. - Advocate for best practices, new tools, and ways of working that improve productivity and quality.

Innovation & Continuous Improvement - Keep abreast of emerging technologies and frameworks, evaluating their potential fit. - Propose and lead experiments or spikes that can modernise our stack. - Help shape development standards and processes to ensure we’re always improving.
