What you'll do

  • Test camera-based jaw tracking across devices, lighting, faces, glasses and beards
  • Find the conditions where measurements break, and help the team fix them
  • Own the release checklist for every iOS and Android build
  • Test accessibility, German texts, performance, slow networks and offline use
  • Write clear bug reports in Linear, with steps to reproduce and evidence
  • Keep test evidence documented, as our product requires
  • Review the daily data-quality checks across Amplitude, AppsFlyer, RevenueCat and BigQuery, and investigate what they flag
  • Find out why two tools disagree, and get it fixed
  • Keep our tracking plan in sync with what the app actually sends
  • Use AI tools to write automated tests (Maestro), generate test cases and run checks
  • Review what AI produces: you are the person who decides whether it is right

What we're looking for

  • Enrolled at an EU university with a mandatory internship in your study regulations, or at a Spanish university that signs a convenio for prácticas
  • Available 20 to 40 hours a week, remote, as your university allows
  • Fluent in English (the app is in German; the team works in English)
  • Solid SQL
  • A structured, curious way of testing: you find the edge cases others miss
  • You already use AI tools (Claude, ChatGPT, Cursor or similar) in your daily work

Nice to have

  • Test automation (Maestro, Detox, Appium)
  • Accessibility (WCAG, VoiceOver, TalkBack)
  • Product analytics (Amplitude, Mixpanel, GA4) or attribution (AppsFlyer)
  • Dbt or Dataform, Git, Python
  • Interest in computer vision, health tech or medical device quality

Benefits

  • Compensation: €300 per month
  • Real ownership: you own the release checklist, and when you say a build isn't ready, we listen
  • Work with AI from day one: you learn how to run quality at scale with AI, a skill few people have yet
  • Rare experience: computer vision, health data and quality in a health product, all in one role
  • Mentorship: a weekly 1:1 with our CTO
  • Hours that fit your studies: 20 to 40 hours a week, as your university requires

How to get hired

  1. 1Send your CV and your university document (internship requirement, or confirmation that your university can sign a convenio)
  2. 2A 30-minute call with our team
  3. 3A short trial task: we send you a test build of the app, and you spend about 2 hours finding and reporting what's wrong. Use any AI tools you like
  4. 4A final conversation, and an offer within a week
