Zynca is looking for a proactive and experienced Senior Front-end Developer to join our growing team in the labor market services and recruitment domain. In this role, you will play a key part in building and shaping modern web applications that directly impact how candidates and employers connect. We are looking for someone who not only delivers high-quality code, but also actively contributes ideas, improvements, and technical direction.
As a Senior Front-end Developer, you will design, implement, and maintain scalable front-end solutions using React, Next.js, and TypeScript. You will work closely with designers, backend developers, and product stakeholders to turn ideas into well-crafted user experiences. A significant part of the role involves building reusable UI components with Tailwind CSS, integrating applications with GraphQL APIs, and ensuring high standards in performance, accessibility, and code quality.
We expect you to take ownership of features from early concept through development and production, proactively identify areas for improvement, and suggest solutions that enhance both the product and the development process. You will have the autonomy to influence technical decisions, challenge existing approaches when needed, and help evolve the front-end architecture in a sustainable way. Staying up to date with modern front-end trends and best practices is an important part of this role.
The ideal candidate is a Senior Front-end Developer with strong experience in React and Next.js and strong TypeScript skills. Hands-on experience with Tailwind CSS and GraphQL is required, along with a good understanding of modern web performance, accessibility standards, and responsive design.
The role demands a strong eye for visual detail - spacing, typography, alignment, and motion and the ability to translate complex designs into clean, performant, and maintainable code. You will apply advanced frontend techniques, including modern CSS, layout systems, animations, and performance optimizations, to achieve pixel-perfect design fidelity without compromising usability or scalability.
We value a proactive and independent mindset, ownership of delivered solutions, and the ability to collaborate effectively within a cross-functional team.
At Zynca, we offer a competitive salary, opportunities for professional growth, and a collaborative, transparent work environment where your ideas and initiative truly matter. You will have a real impact on both the product and the technical direction of the company while helping transform the recruitment and labor market landscape.
To apply, please submit your CV along with a portfolio or GitHub profile showcasing your recent front-end work.

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.
