Next up: a B2B platform release in early 2027.\nHow this internship works\nWe offer this role in exactly two ways:\nMandatory internship at an EU university: you are enrolled at a university in the EU and your study regulations require an internship. You send us a document from your university that confirms this. Start as soon as possible.\n\nPrácticas at a Spanish university: you are enrolled at a university in Spain, and the internship runs through your university's internship agreement (prácticas extracurriculares with a convenio), full-time or alongside your studies. Start from December 2026.\n\nWe can't offer working-student contracts, voluntary internships or freelance work.\nThe role\nYou make sure our app and our numbers can be trusted, and you use AI to do it at a scale one person couldn't before. AI handles the repetitive checks; you handle what needs human judgment, like testing our camera features in the real world. You work directly with our CTO and founding engineer.\nAbout 60 % app and computer vision quality: real-world testing, releases, accessibility, performance\n\nAbout 25 % data quality: making sure analytics data is complete and correct\n\nAbout 15 % automation with AI: building automated tests and checks, and reviewing what they find\n\nWhat you'll do\nTest our computer vision in the real world\nTest camera-based jaw tracking across devices, lighting, faces, glasses and beards\n\nFind the conditions where measurements break, and help the team fix them\n\nOwn app quality\nOwn the release checklist for every iOS and Android build\n\nTest accessibility, German texts, performance, slow networks and offline use\n\nWrite clear bug reports in Linear, with steps to reproduce and evidence\n\nKeep test evidence documented, as our product requires\n\nKeep our data trustworthy\nReview the daily data-quality checks across Amplitude, AppsFlyer, RevenueCat and BigQuery, and investigate what they flag\n\nFind out why two tools disagree, and get it fixed\n\nKeep our tracking plan in sync with what the app actually sends\n\nAutomate with AI\nUse AI tools to write automated tests (Maestro), generate test cases and run checks\n\nReview what AI produces: you are the person who decides whether it is right\n\nWhat you bring\nEnrolled at an EU university with a mandatory internship in your study regulations, or at a Spanish university that signs a convenio for prácticas\n\nAvailable 20 to 40 hours a week, remote, as your university allows\n\nFluent in English (the app is in German; the team works in English)\n\nSolid SQL\n\nA structured, curious way of testing: you find the edge cases others miss\n\nYou already use AI tools (Claude, ChatGPT, Cursor or similar) in your daily work\n\nNice to have\nTest automation (Maestro, Detox, Appium)\n\nAccessibility (WCAG, VoiceOver, TalkBack)\n\nProduct analytics (Amplitude, Mixpanel, GA4) or attribution (AppsFlyer)\n\ndbt or Dataform, Git, Python\n\nInterest in computer vision, health tech or medical device quality\n\nWhat we offer\nCompensation: €300 per month\n\nReal ownership: you own the release checklist, and when you say a build isn't ready, we listen\n\nWork with AI from day one: you learn how to run quality at scale with AI, a skill few people have yet\n\nRare experience: computer vision, health data and quality in a health product, all in one role\n\nMentorship: a weekly 1:1 with our CTO\n\nHours that fit your studies: 20 to 40 hours a week, as your university requires\n\nHow we hire\nSend your CV and your university document (internship requirement, or confirmation that your university can sign a convenio).\n\nA 30-minute call with our team.\n\nA 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.\n\nA final conversation, and an offer within a week.\n\nDetails\nType: mandatory internship (EU university) or prácticas (Spanish university)\n\nHours: 20-40 per week, depending on your university\n\nLocation: remote within the EU\n\nCompensation: €300 per month\n\nStart: as soon as possible; prácticas in Spain from December
