Join Tylko, Where Design Meets Technology Founded in Warsaw, Poland, in 2015, Tylko is redefining how we design, shop for, and experience furniture. Frustrated by mass-produced, one-size-fits-all solutions, the team created something smarter: bespoke storage that balances cutting-edge technology, premium craftsmanship, and sustainable production. With millimetre-perfect precision, every piece is made-to-order and crafted locally, minimising waste and maximising longevity. The result? A new standard in furniture – one that fits your space, your style, and your life. Why It Matters We’re not just building furniture. We’re changing how people think about living with it. By merging technology and design, we help people create spaces that truly reflect who they are. If you believe that good design can make everyday life better, you’ll feel right at home here. How We Work We believe in small teams, big ideas, and simple processes. No endless paperwork, no silos. Just open communication, shared goals, and a healthy dose of curiosity. We start small, think big, and move fast, because progress always beats perfection. At Tylko, collaboration and trust aren’t buzzwords — they’re how we work. From day one, you’re part of a team that makes real decisions and brings them to life together. You’ll have the freedom to share ideas, turn them into action, and shape the space around you literally. Here, learning isn’t a bonus. It’s part of the job. About The Role and Team We’re looking for a Senior Frontend Developer to join our ECOM Team. The ECOM Team is the heartbeat of Tylko’s online store. The place where design meets conversion, and code meets customers. We make sure every pixel, animation, and interaction feels effortless. From browsing products to configuring furniture and checking out. Our stack? Vue 3, Nuxt 3, TypeScript, and a sprinkle of Node.js magic. We’re obsessed with the performance, Core Web Vitals, and clean architecture. If something’s slowing users down, we hunt it, fix it, and ship improvements faster than you can say “CLS”. We work closely with design, data, and backend teams to make sure that what we ship doesn’t just look good - it performs, scales, and sells. Work here isn’t about closing jira tasks - it’s about co-creating our business. Once you join our team, you will: • Lead the development of key modules of our e-commerce platform (checkout, configuration, CMS frontend). • Build fast, reliable, and elegant frontends that keep up with our growing user base. • Take ownership of performance and architecture decisions across our Vue/Nuxt codebase. • Review code, mentor teammates, and set the bar high for code quality. • Collaborate with designers and UXers to make every interaction feel right. • Work hand in hand with backend, data, and QA engineers to deliver seamless experiences end-to-end. • Keep a watchful eye on Core Web Vitals, accessibility, and DX — because every millisecond and every detail matters. • Work with server-side rendering and caching strategies to keep our storefront lightning-fast and SEO-friendly. • Introduce and document improvements that make our developer experience smoother Why Tylko? At Tylko, you’re not just writing code. You’re shaping how people design and buy furniture. We keep things human, value transparency, and build products we’re proud of. We give our teams room to experiment, learn, and grow. Because that’s how the best ideas happen. Perks: • One bonus day off every month (yep, really) • Comprehensive healthcare • Multisport membership • A juicy discount on all Tylko products • Dog-friendly office (woofs encouraged) You will be fairly remunerated (depending on your skills and experience) – 22.000 - 25.500 PLN for a B2B contract. What we’re looking for: • 5+ years of commercial frontend experience • Deep knowledge of JavaScript, Vue 3, and Nuxt (React/Next welcome too) • Hands-on experience with SSR and static site generation (Nuxt or similar frameworks) • Strong grasp of HTML, CSS, and modern component design principles • Solid understanding of Core Web Vitals and frontend performance profiling • Experience building and optimizing high-traffic SPAs (performance, SEO, accessibility) • Practical experience with CI/CD pipelines and debugging tools (Sentry, Datadog, or similar) • Great communication in Polish and English • Working from our Warsaw office at least 3 days a week — because some things are just better face-to-face We’ll be extra impressed if you have: • A passion for UI polish, animations, and smooth microinteractions • Interest in DX, developer tooling, or automation • An opinion on whether tabs or spaces are objectively superior (and arguments to back it up)

About Pleo Messy spend management is tricky business. And tedious processes are a lose-lose situation for all involved, not just finance. At Pleo, we're changing that. We build spend solutions that make managing money seamless, empowering, and surprisingly effective for finance teams and employees alike—with a vision to help all businesses ‘go beyond’. The word ‘Pleo’ actually means ‘more than you’d expect’, and living by that mantra has been the secret to our success over the last 10 years. Now, we’re at a pivotal moment in our journey; every move we make has a direct impact on our 40,000+ customers, our business, and our collective success. We need people who take pride in uncovering customer needs, who turn complex problems into simple solutions, challenge the way things are done (respectfully), and always aim high. With great ambitions driving us forward, we can’t say we’ve got this whole thing figured out. And frankly, that’s half the fun! What we can say is that we’re a driven, progressive, and, importantly, a kind bunch of 850+ people from over 100 nationalities, all committed to delivering the future of business spending, together. We at Pleo are on a mission to make spend management surprisingly effective and empowering. We build a product used by thousands of companies across Europe, and our design system is a core part of delivering a consistent, accessible, high-quality experience.
