• Core Development & Architecture: Design, engineer, and implement complex software user interface components using React.js and modern JavaScript frameworks. • Performance & Quality: Obsess over application performance, optimize code for maximum speed, accessibility, and cross-browser compatibility. • Write robust executable tests (Unit, Integration, E2E). • Support the implementation of UI-specific CI/CD pipelines. • Collaborate closely with UI/UX designers, Back-End Engineers, and Product Owners to ensure technical feasibility matches product goals. • Mentor junior developers through code reviews, pair programming, and enforcing high-quality coding standards.

• Build the future of email at Hostinger — create and evolve the interfaces used by millions of customers to manage their email hosting and communicate every day. You'll work across two real products: • Webmail — our modern, fast, web-based email client • hPanel Email — the interface customers use to set up, manage, and upgrade email services (admin panel) • Own complex features end-to-end. From new Webmail functionality to improved setup and monetization flows, you’ll shape solutions from first discussions through architecture, coding, testing, and release. • Collaborate deeply. Work closely with backend engineers, designers, and product managers to co-create solutions, define APIs, and launch impactful features. • Work with Vue.js 3 & TypeScript daily. • You'll build scalable SPAs using the Composition API, Pinia (hPanel), and TanStack Query (Webmail). • Write meaningful unit tests with Vitest + Testing Library and keep our code quality high. • Make the UI fast, reliable, and built for scale. Optimize for millions of users across browsers, devices, and slow networks. Ensure every interaction feels smooth, stable, and trustworthy. • Improve developer experience. Influence tooling, internal libraries, test strategy, and shared components across teams. • Contribute to company-wide FE guild initiatives and push the overall quality bar higher. • Put security at the heart of your code. Email is extremely private — your work must protect user data, avoid leaks, and uphold trust. • Use and shape modern AI-powered workflows. We rely heavily on AI tools like Cursor, Claude Code, and CodeRabbit to boost velocity and code quality. We welcome new ideas, workflows, and experiments that elevate our engineering capabilities.

• Design solutions: Define the best technical solutions to business problems • Ship working code: work with React on the frontend and Kotlin microservices with Postgres on the backend • Deploy and iterate: We release frequently to our customers • Build your competency: You will learn quickly by building market-leading technology • Maintenance and troubleshooting: Carefully monitor our services, catching errors before users notice them

• Design, build, and maintain high-quality front-end features using modern JavaScript and React • Deliver features and enhancements aligned to product roadmaps and sprint goals, with a strong focus on usability, performance, and code quality • Work collaboratively with product, UX/UI, QA, and backend engineers to translate requirements into well-designed solutions • Own the implementation of simple to moderately complex user stories, from development through testing and deployment • Identify, investigate, and resolve front-end bugs and issues efficiently • Contribute to testing, code reviews, and continuous improvement within an Agile and DevOps delivery environment • Maintain and improve front-end standards, patterns, and best practices to support long-term scalability and maintainability
