Job Description

About HOLY HOLY is the soft drink revolution: With our product lines Energy®, Iced Tea®, Hydration®, Milkshake®, and our newest innovation, the HOLY Syrup Bottle® you get amazing taste across 50+ flavors while maintaining a good conscience—for your body & the environment. Over 2M loyal customers: Started in a shared apartment by three best friends, we have scaled to Europe's fastest growing consumer brand—and our cult-like community, the HOLY Squad, loves it: 4.6 stars on reviews.io speak for themselves. From D2C to Global Omnichannel: In less than four years, we've profitably scaled HOLY to more than €180M D2C revenue in DACH, FR, UK and PL. Now scaling our retail business, we're on an exciting transition to becoming a true omnichannel rocketship. We are still just getting started: Backed by the world's best consumer investors, we aim to revolutionize the soft drink industry and build a generational love brand: tastier, healthier & more sustainable. Our team of 170+ people aims high (Coca-Cola, we're coming for you!). About the Position Creative excellence is a pillar of our strong HOLY brand, beloved by thousands of HOLY Squad members. Our in-house Creative Studio sits at the heart of that, a cross-disciplinary team of designers, writers, and videographers working together to produce work that builds the brand and drives performance. Their output reaches thousands of new customers every month, converting them into true brand enthusiasts across channels and regions. We're looking for a Senior UI/UX Designer to join our Creative Studio as the primary design owner of the HOLY Shop. You'll be responsible for the customer journey and design quality across our entire Shop, from homepage to checkout, across four markets. That means building and governing the design system that makes us scalable, designing the experiences that convert visitors into Squad members, writing the specs our external dev agency builds from, and QA-ing their output before anything goes live. Working as a dedicated partner to the Shop team, you are the bridge between HOLY's creative vision and how it actually performs in market, and this is your chance to shape that from the ground up. Responsibilities: Design system ownership: Build, govern, and scale HOLY's Figma component library – the foundation for visual consistency, speed, and on-brand execution across the Shop. Brand storytelling: Lead the optimization of HOLY's highest-impact pages as part of the roadmap; translating brand narrative into experiences that educate and convert. Design handoff and QA: Write precise, documented design specs that external developers can build from without guesswork. QA their output in staging to catch responsive and visual regressions before every deploy. Mobile-first design: Design and specify responsive experiences across all breakpoints, with mobile as the primary canvas for ~89% of traffic. Define interaction states, edge cases, and layout behavior for all screen sizes. Conversion and upsell mechanics: Design upsell and conversion mechanics (such as our Mix & Match bundle builder, cart and checkout upsell, and freebie incentive pages) in close collaboration with the CRO Manager. Campaign landing pages: Deliver new pages at pace for flavor and product category launches, balancing velocity with design system consistency. A/B testing and data literacy: Contribute to test hypotheses across all design work and use analytics (GA4/Shopify) to interpret results and inform future design decisions. Cross-functional partnership: Act as the bridge between the Creative Studio and the Shop team, co-owning how the HOLY brand comes to life on the Shop, and collaborating closely with a Senior Graphic Designer, external devs, CRM, and the CRO Manager. About You UI/UX expertise: 5-8 years designing for conversion-driven D2C or e-commerce brands, with a strong mobile-first portfolio. Deep familiarity with core page types – product detail, collection, cart, checkout, navigation, and loyalty flows. Track record of improving CVR, AOV, or RPS. Technical UX fluency: Able to read (not write) HTML, CSS, and Liquid. Understands Shopify theme architecture and metaobject concepts well enough to spec realistically, perform light theme-editor tweaks, and have productive conversations with developers. Figma expertise: Advanced command of components, variants, auto-layout, prototyping, and tokens. Has built or governed a component library at scale and knows how to implement and enforce adoption across a team. UI design sensibility: Able to interpret and apply HOLY's brand guidelines and creative direction to Shop UI, translating vision from the Creative Studio into on-brand execution. Secondary to UX, but important for maintaining visual consistency across all of HOLY's channels. Senior-level ownership: Self-directed, proactive, and detail-oriented. Drives work end-to-end without hand-holding, holds standards, and raises the bar rather than waiting to be pushed. Nice to have: Exper
