The difference you'll make: You’ll join our Web Infrastructure team, reporting to the Senior Lead Engineer. Working predominantly on our Design System, you’ll partner closely with our Principal Product Designer to evolve it into a platform that drives quality, efficiency, and growth. You’ll play a pivotal role in elevating product quality across loveholidays’ customer-facing experience. You’ll help bridge design intent and frontend implementation, enabling our teams to move faster and deliver more cohesive experiences as AI-assisted development becomes central to how we build. This is a critical moment for our design system to mature and play a bigger role in how we deliver better products and outcomes. It’s a rare opportunity to shape the visual and interactive foundations of a product used by millions of travellers, working at the intersection of design craft, frontend engineering, and developer experience. Web infrastructure sits within our Platform function, which builds the technology and shared capabilities that power the loveholidays experience. By creating scalable products, systems and tools, Platform helps the wider organisation move faster, work more independently and deliver better outcomes for customers. Your day-to-day: Operationalise the design system – co-lead its evolution and governance, build and maintain a robust component library in React/TypeScript, and establish clear adoption standards across product teams – enabling the operational loop between Figma, code, and multi-brand delivery Enable AI-assisted development – help define how our design system supports AI-generated frontend code (Claude Code, Cursor and similar tooling), reducing rework and improving consistency of AI output, whilst enabling innovation and experimentation at scale Bridge design and engineering – work closely with product designers and engineers to translate design decisions into reusable, production-ready components Raise the quality bar – review design system features before release to ensure they meet high UX and consistency standards; make targeted visual and interaction refinements aligned with design system guidelines Improve developer experience – partner with engineers to make the system intuitive to use, well-documented, and a genuine accelerant Cross-functional alignment – collaborate with design leadership, product managers, and engineering to ensure the system reflects evolving product priorities Your skillset: Proven experience in design systems work – you've built, maintained, or significantly evolved a component library, token architecture and associated documentation in a production environment, supporting multi-platform delivery (web, iOS, Android) Strong frontend engineering skills – you are expert in React, TypeScript, and modern CSS; and experienced with industry-standard documentation tooling Design sensibility – you can make considered visual and interaction decisions, not just translate specs into code Systems thinker – you understand governance, versioning, and how to drive adoption across teams without mandating it; you can anticipate the downstream impact of design system choices and validate them at scale Experience working alongside AI coding tools – you think critically about how component structure and documented guardrails affect the quality and consistency of AI-generated output Data-informed – you use component usage analytics, adoption metrics, research insights, and performance data to guide decisions, not just intuition A collaborative and clear communicator – you're as comfortable pairing with a designer on a component spec as reviewing a PR with an engineer, and you write documentation, rationale, and migration guides that engineers and designers can easily consume. Deep commitment to web performance – you understand how design system decisions affect Core Web Vitals at scale, and take pride in helping loveholidays remain the fastest in travel Deep commitment to accessibility – because opening up travel to everyone isn't a nice-to-have Your previous experience should contain examples of great work and clearly defined outcomes. It should cover more than just the design visuals and include the process on how you got there and the structure around you that got you there.
