Position: Frontend Developer (Nuxt 4 / Vue 3 / TypeScript) Warsaw, Poland

• Hybrid (1 day per week in the office)

Compensation: 12,000–15,000 PLN per month, depending on experience and agreed terms. Why this role matters

We're looking for a frontend engineer to join our small team as its second frontend developer. This is a high-ownership role where you'll have a direct impact on product quality, performance and architecture from day one.

We're running a modern stack and recently upgraded to Nuxt 4. We keep our dependencies up to date, but there's still plenty of room to make things better — from performance and test coverage to developer tooling and architecture.

We're looking for someone who enjoys taking ownership, spotting opportunities for improvement and turning them into practical solutions.

What you'll do

• Build and evolve our Nuxt 4 / Vue 3 application, including offer listings, search, negotiation chat, checkout, and seller and admin dashboards.
• Own frontend performance and technical SEO across our public pages, including SSR, Core Web Vitals, bundle size, image optimisation, sitemaps and structured data.
• Deliver features for a B2B marketplace used by professionals across Europe.
• Build and maintain real-time features with Pusher, Algolia-powered search and recommendations, and data-intensive tables and charts.
• Improve code quality and developer experience by introducing unit testing alongside our Playwright E2E suite, modernising tooling and reducing technical debt.
• Work closely with our designer, Laravel backend team and business stakeholders to turn product requirements into reliable solutions.
• Contribute to architectural decisions and help shape our long-term technology choices.

What you'll bring

• 3+ years of commercial frontend development experience.
• Strong knowledge of Vue 3, the Composition API and TypeScript with strict type checking.
• Production experience with Nuxt 3 or 4, including SSR, hydration challenges, route rules and server-side logic in Nitro.
• Experience integrating REST APIs.
• A solid understanding of web performance and technical SEO.
• Experience building complex, stateful interfaces with Pinia.
• The ability to work independently, take ownership and make well-reasoned technical decisions.
• Good English communication skills. Polish is not required.
