Junior Frontend Software Engineer (m/f/x)

We are looking for a Junior Frontend Software Engineer to join our Lake team and work on internal projects as well as rebuy.de , our main platform where thousands of customers come to give products a second life every day. You'll collaborate with experienced developers to build and improve features that directly impact our customer experience, while growing your skills across our tech stack. Working primarily with TypeScript and Angular, you'll also have opportunities to develop backend skills with PHP and Kotlin. This role is perfect for someone early in their software engineering career who is passionate about sustainable technology and eager to learn in a supportive, mission-driven environment.

As our new teammate, you'll collaborate with experienced developers who are eager to mentor you as you grow your skills across our tech stack. You'll have the unique opportunity to touch both backend and frontend technologies - primarily working with TypeScript and Angular. The best part? You won't be stuck maintaining legacy code - you'll actively contribute to new features that directly impact our users' experience.

We're looking for someone who's passionate about learning and not afraid to share ideas. You don't need to know everything yet - we value your fresh perspective and eagerness to grow. You'll work in an environment where asking questions is encouraged, and where "perfect is the enemy of good" - we believe in shipping MVP features and iterating based on real user feedback.

What makes this role special is the balance of support and responsibility. You'll be guided by experienced engineers, but also trusted with meaningful work that matters to our mission. Your contributions will directly help thousands of customers make sustainable choices every day, giving you the satisfaction of knowing your code isn't just running on servers - it's helping the planet.

Being part of our collaborative team means you'll learn not just how to code, but how to think about the full customer journey, collaborate across departments, and make data-driven decisions through A/B testing. This isn't just a job - it's the foundation of an exciting career in sustainable technology.

If you thrive in a dynamic, tech-driven environment and enjoy working with cross-functional teams, we would love to hear from you!
