Senior Frontend Developer | Email product

Your day-to-day

• 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.
