Senior Frontend-utvecklare

Zynca is building an ecosystem of recruiting and matching products, aiming to become the world's #1 choice for candidates and recruiters who are hungry for an 🔥 extraordinary product experience. While 🦕 other companies are releasing convoluted systems with broken features and frustrating interfaces, we are investing our hearts and souls into making sure that Zynca is taking care of everything for you, through smart automations and a world-class user experience that 🌟 simplifies every aspect of your work. In Q3 2026 Zynca will significantly scale up customer acquisition. To prepare for this, we're looking for the next person to take ownership of a core part of the company. 🚀 Senior Front-end Developer As our dedicated Senior Front-end Developer, you will own the frontend side of product flows, interface quality, component architecture, performance, accessibility and the details that make the product feel effortless to use. Rather than being a ticket-taking role, it's a strategic product-building role for someone who wants to shape how Zynca looks, feels and works as we scale. 🎯 The right fit We believe that the right fit for this role has owned frontend work in product-heavy environments before, probably in SaaS, marketplaces, platforms, HR tech, recruitment tech or another digital product where user flows, interface quality and performance matter. You understand how to turn product ideas and design decisions into fast, polished and maintainable user interfaces. You are strong in React, Next.js and TypeScript, comfortable working with APIs, design systems, accessibility, responsive layouts and the small frontend details that make a product feel clear and easy to use. You are senior enough to take responsibility for frontend architecture and technical decisions, but hands-on enough to build components, fix edge cases, improve flows, review details, ship features and make sure the experience holds together in production. You like working close to product and design, and you care about whether the product actually makes the user’s work easier. 💡 About the role What you'll be doing: Own the frontend area across Zynca’s product ecosystem Build and improve user flows, interfaces and reusable components Work closely with product, business and backend to ship features from concept to production Integrate frontend applications with APIs and GraphQL Improve performance, accessibility, responsiveness and overall interface quality Maintain and evolve our design system and component architecture Identify weak spots in the product experience and improve them before users have to complain Tech stack: React 19 - Latest React with server components, hooks, concurrent features Next.js 15 - App Router, server/client components, middleware, Turbopack TypeScript 5 - Strong typing, generics, utility types GraphQL - Apollo Client, queries/mutations, caching strategies, codegen Tailwind CSS 4 - Utility-first styling, tailwind-merge, tailwind-variants React Hook Form + Zod - Form handling with schema validation Design System - Mix of shadcn/radix and custom UI library 🥳 Company culture You will join a senior, hands-on company where people are expected to think, challenge, take responsibility and move things forward without waiting for permission. We work closely across product, sales and customer work. Feedback is direct, decisions are made quickly, and everyone is expected to care about the full customer experience, not just their own area. 🎉 Interested? Does this sound like the right role for you? If so, don't hesitate to apply! We'd love to hear from you! Öppen för alla Vi fokuserar på din kompetens, inte dina övriga förutsättningar. Vi är öppna för att anpassa rollen eller arbetsplatsen efter dina behov.
