About the role

We’re looking for a **Medior Front-End Developer** to join us **on-site in Mostar** and help build modern SaaS products for an international market.

We work on **real production applications** with real users, real traffic, and clear engineering standards. We’re looking for someone who takes ownership, writes high-quality code, and wants to build a product long-term — not just “complete tasks.”

Tasks

**Technologies we use**

  • **React**
  • **Next.js**
  • **Tailwind CSS** (or similar utility-first styling)
  • **JavaScript (ES6+)** _(TypeScript is a plus)_
  • **REST API integrations**
  • **Git** (feature branching, pull requests, code reviews)

**What you’ll do**

  • Build and maintain front-end features using **React + Next.js**
  • Implement responsive UI with strong attention to UX details
  • Integrate the UI with backend services via **REST APIs** (data fetching, auth flows, error handling)
  • Help shape and improve front-end architecture (component structure, state patterns, maintainability)
  • Improve performance and quality (rendering, bundle size, caching strategies where relevant)
  • Collaborate closely with backend and product to deliver features end-to-end
  • Participate in code reviews and help keep engineering standards high

Requirements

**What we expect**

  • **5+ years** of professional experience in front-end development
  • Strong knowledge of **React** (modern patterns, hooks, component architecture)
  • Experience with **Next.js** (routing, SSR/SEO basics, data fetching patterns)
  • Excellent understanding of **HTML/CSS**, modern layout, and UX principles (not just “it works”)
  • Solid **JavaScript (ES6+)** skills
  • Experience integrating front-ends with **REST APIs**
  • Ability to work independently and make sound technical decisions
  • Experience working on **production applications** (not only demo projects)
  • Willingness to work **fully on-site in Mostar** (this is not a remote role)

**Nice to have (not required)**

  • **TypeScript**
  • Testing experience (e.g., **Jest, React Testing Library, Playwright/Cypress**)
  • Experience with a UI library or design system (e.g., **MUI/Chakra/AntD**, or internal systems)
  • Strong understanding of **performance, SEO, and front-end optimization**
  • Great eye for design and details (pixel/UX polish)

Benefits

**What we offer**

  • Work on real products (no agency churn)
  • Technically challenging work with clear standards
  • Real impact on product architecture and direction
  • Long-term collaboration and stability
  • A comfortable on-site work environment in Mostar
  • Compensation based on experience and skill level
