About JawBuddy

JawBuddy helps people with jaw pain, teeth grinding and TMJ problems through a guided exercise app. Our app measures jaw movement through the phone camera using computer vision and AR, so users see their progress in real numbers.

We are a small, funded health-tech team with paying customers in Germany. Next up: a B2B platform release in early 2027.

How this internship works

We offer this role in exactly two ways:

Mandatory 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 .
Prácticas 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 .

We can't offer working-student contracts, voluntary internships or freelance work.

The role

You 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.

About 60 % app and computer vision quality: real-world testing, releases, accessibility, performance
About 25 % data quality: making sure analytics data is complete and correct
About 15 % automation with AI: building automated tests and checks, and reviewing what they find

Test our computer vision in the real world

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

Keep our data trustworthy

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

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

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

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

Send your CV and your university document (internship requirement, or confirmation that your university can sign a convenio).
A 30-minute call with our team.
A 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.
A final conversation, and an offer within a week.

Type: mandatory internship (EU university) or prácticas (Spanish university)
Hours: 20–40 per week, depending on your university
Location: remote within the EU
Compensation: €300 per month
Start: as soon as possible; prácticas in Spain from December 2026
