Your role at Hostinger

Join Horizons - the team exploring and building AI-powered products that don’t have industry playbooks yet.

As a Horizons Quality Engineer, you won’t just test features - you’ll define what “correct” means for AI systems that didn’t exist three months ago. This isn’t a traditional QE role with predefined test cases or stable requirements.
You’ll operate in high ambiguity, where the product evolves weekly and the rules are still being written.
Your impact will go beyond finding bugs - you’ll shape how we evaluate AI at Hostinger, define best practices, influence product decisions, and raise the quality bar for intelligent tools used by millions.

This role is for someone who sees ambiguity as opportunity, not chaos - someone who doesn’t wait for documentation, but creates it, and who builds confidence in the future of our AI products.
