Frontend (React) Developer

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
