Backend Engineering Intern (all genders)

We love the magic of memory keeping

At Journi, we’re on a mission to build the world’s most-downloaded printing app.

With over 10 million users worldwide, we help people turn their favorite moments into beautifully designed Photo Books and Prints. Our smart AI makes the process fast, simple, and joyful, so our users can spend less time editing and more time reliving their best stories.

🥁 About the internship

Join our backend team and help build the core of one of the world’s leading printing apps. As an intern, you won’t be doing “practice tasks” - you’ll work on real features and systems alongside experienced engineers, contributing to products used by real users in production!

This role is open to students, recent graduates, or anyone looking to grow their backend skills in a production environment. We are unable to sponsor visas for this internship. Candidates must already have a valid EU work permit and be based in Vienna.

Please note: This is a rolling internship opportunity, with applications reviewed on an ongoing basis. The internship duration is 4-6 months, and the exact start date is aligned with team availability and business needs. The position may be temporarily paused once we have successfully filled the current opening.

• Contribute to the backend of our printing platform (built with Scala and JVM technologies)

• Support the development of new features and REST APIs used by millions of users

• Collaborate closely with frontend engineers, product designers, and product managers

• Work on improving the performance, scalability, and reliability of our systems

• Help identify bugs, technical debt, and areas for improvement - and be part of fixing them

• Write clean, maintainable code and contribute to code reviews

• Learn how production systems are built, tested, and deployed

🎒 Your bag of tricks

• Basic to intermediate experience in backend development (through studies, internships, or personal projects)

• Familiarity with at least one JVM language (Java, Kotlin, or Scala) (No Scala experience? No problem - as long as you’re excited to learn it!)

• Understanding of REST APIs and how web applications communicate

• Basic knowledge of databases (SQL or NoSQL)

• Some exposure to Git and collaborative development workflows

• Curiosity, ownership, and a willingness to learn by doing

• Good communication skills and a collaborative mindset

🔥 Nice-to-haves

• Some experience with Docker, cloud platforms (AWS), PostgreSQL, Redis

• Personal or academic projects (GitHub links welcome!)

• Interest in system design, scalability, or performance

• Curiosity about microservices or distributed systems

✨ What we offer

A happy team makes for a happy workplace. We wouldn’t be able to do what we do without our team, and that’s why we offer:

• A monthly gross salary starting at € 1.410,00.
