Who you are

7+ years' experience in front-end or full-stack development, with 2+ years in a lead or senior technical role
Deep expertise in modern JavaScript/TypeScript and front-end frameworks (React, Next.js, Vue, or similar), with strong HTML, CSS/SCSS foundations
Proven experience integrating with RESTful APIs, working with backend engineers, and connecting third-party platforms (e.g., payment providers, CRM, marketing tools)
Hands-on experience with analytics and tag management (GA4, GTM, Segment, Mixpanel, or similar), including conversion tracking and pixel implementation
Solid understanding of A/B testing, experimentation platforms, and a data-driven approach to optimising conversion funnels
Strong grasp of technical SEO and web performance optimisation
Experience mentoring developers, leading technical discussions, and raising engineering standards across a team
Comfortable with Agile practices, Git, CI/CD pipelines, and cloud platforms (Azure preferred)
Excellent communicator who can bridge technical and non-technical stakeholders across Tech, Marketing, Product, and Data
Bonus: experience with Webflow, headless CMS, server-side rendering (SSR/SSG), or a background in growth engineering
If you're excited about this role but don’t meet every requirement, we still encourage you to apply, your unique skills and experiences might be exactly what we need now or in the future

What the job involves

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
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 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
_________________________________________________________________________________________
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
