We ship multiple times a day. Tests catch regressions. You catch what machines can’t.

This role is not about ticking boxes or validating acceptance criteria. It’s about living inside the product, thinking like a user, and steering us toward a better experience—every single day.

What you’ll do

• Manually test new features alongside a strong automated test suite
• Explore the product like a real user: find edge cases, inconsistencies or confusing flows

• Write clear, actionable bug reports that engineers can fix fast
• Work closely with engineers and the CTO in a Continuous Delivery environment

What we’re looking for

• You’re curious, observant, and slightly obsessive about details
• You care deeply about user experience and product quality
• You think in scenarios, not just requirements
• You communicate clearly in English, especially in writing
• 1-3 years of QA experience in an agency or start up

Technical knowledge (HTML, CSS, JavaScript, etc.) is nice to have, not required.

Why you’ll like it here

• Real ownership over product quality and user experience
• Work with a sharp, motivated team that gets things done
• Continuous delivery: your feedback influences what ships today, not next quarter
• Remote-first, with a killer Berlin office when you want it

If you want to learn how high-quality software is really shipped—and how great products feel, not just function—this role is for you.
