Job description

Join the team building an AI-first company

Hostinger serves more than 5.5 million clients across 150 countries, but we're still excited about what we're creating next.

AI is changing how we build products, support customers, work together, and solve problems. It helps us move faster, spend less time on repetitive work, and focus on bigger ideas.

If you want your work to influence both what we build and how we build it, we'd like to meet you.

Our culture:

Guided by 10 company principles.

Your role at Hostinger

You’ll join Hostinger AI Builder - the team building an AI-powered platform that helps anyone turn an idea into a website, online store, or web app.

This isn’t a \"ticket-to-deploy\" role. You’ll own problems end-to-end: from identifying customer needs to shipping solutions and measuring their impact.

We move fast, with high autonomy and broad ownership. AI agents are part of how we build every day - helping us experiment faster and solve bigger problems.

Paulius Gedminas, Head of Engineering for Ecommerce & AI builder
