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
