Requirements
• Proven experience building and evolving multi-platform design systems (Web, iOS, Android).

You can anticipate the downstream impact of architectural choices and drive cross-team consistency without relying on mandates • A collaborative communicator with strong design sensibility.

You take pride in writing migration guides and documentation that are easy to consume, ensuring the system remains high-quality and "AI-ready" for coding assistants • A deep commitment to web performance. You understand how design system choices impact Core Web Vitals at scale and are driven to ensure loveholidays remains the fastest travel platform in the industry • You treat accessibility as a core requirement, not a "nice-to-have." You ensure that our component guardrails make it easy for every engineer to build inclusive experiences that open up travel to everyone • Knowledge and understanding of the travel sector or other D2C e-commerce environments • Experience building design system foundations that supports multi-brand/white-label architecture and internationalisation at scale • The interview journey: • 1. TA screening - 30 mins • 2. 1st stage interview with the Hiring Manager - 45 mins • 3. Tech challenge - you can choose between a live and take home option • 4. Final stage - consisting of discussions around three key areas
