🍿 About Staycation For most people, hotels are places you only visit when you travel. But we see something different. Behind their doors, hotels hide some of the most extraordinary spaces cities have to offer: breathtaking rooftops with skyline views, world-class spas and pools, bars and restaurants led by visionary chefs, interiors that spark the imagination, and beds so perfect you never want to leave them. Yet, most of these spaces remain invisible to the people who live just a few streets away. Staycation was born from a simple belief: the most inspiring places in your city shouldn’t be reserved for tourists. They should be part of your everyday life, an alternative to a dinner-date at a restaurant, a spontaneous midweek escape, or a unique way to celebrate a special moment. Our mission is to transform hotels into a new form of urban entertainment. Places people turn to when they want to feel, connect or recharge. Whether it’s 24 hours, 48 hours, or just a few hours, we’re reinventing the way people experience the cities they call home. Today, Staycation means: • 🌍 5 million users in France, the UK, Spain, Belgium and Switzerland • 🏨 4,000 partner hotels among the best 4★, 5★ and iconic palaces • ⭐️ 9.3/10 average rating for our experiences Joining Staycation means becoming part of a passionate, creative, and ambitious team on a quest to redefine what hospitality and city life can be. ✨ The role We’re hiring a Fullstack Developer to strengthen our Product & Engineering team. You’ll join one of our cross-functional product squads, working closely with a Lead Developer, a Product Manager, a Product Designer and other Fullstack Developers. Your role will be to turn user problems into reliable product increments, contribute from discovery to production, and balance impact, speed, quality and maintainability. We’re open to both experienced and senior individual contributors, and we’ll calibrate the scope based on what you have already owned and delivered. You may be stronger in either frontend or backend, but you should be genuinely comfortable contributing across both and motivated to keep growing on the full stack. You’ll report to the Lead Developer of your squad and be part of the Product team led by Robin , our CTO & Head of Product. 📍 Key responsibilities • Design, build, test, deploy and monitor product features across the frontend and backend. • Work closely with Product Management and Product Design from the problem-definition stage, helping shape the solution rather than simply implementing a finished specification. • Break down projects into clear increments, estimate your work, identify dependencies and risks, and communicate early when the plan needs to change. • Take ownership of what you ship in production, from instrumentation and monitoring to incident diagnosis and continuous improvement. • Contribute to high-quality code reviews, pragmatic testing strategies, refactoring and the active management of technical debt. • Document decisions, share knowledge and help improve our engineering practices and codebase over time. • Depending on your level, plan multi-week projects, design architectures that others can implement and introduce practices that continue to work without you in the loop. 🧰 Our tech environment Four products running on a shared stack: • The website (React / Next.js), our storefront and booking funnel. • The mobile app (React Native), used daily by our users, with its own release cycles and performance stakes. • The hotel extranet , where our partners manage their offers, inventory, bookings, billing, timeslots. • The internal admin platform , the tool our teams use to run the marketplace. On the back-end side: micro-services in NestJS and more, PostgreSQL for our databases, ho
