Learning & Growth: Gain mentoring from experienced professionals and access to proven processes that prepare you for success in a fast-paced tech environment.
Our Culture of Excellence: Embrace modern systems like the Entrepreneurial Operating System (EOS) to deliver outstanding performance and achieve ambitious goals.
Collaboration & Fun: Be part of a driven team that values humor, creativity and shared experiences, with regular team events and occasional meetups.
Flexibility: Work remotely, from our modern office in Cologne, or a mix of both—whatever helps you thrive.

Tasks

Your Responsibilities

Contribute to Open Source: Write, maintain, and enhance open-source projects like Sidebase and actively engage with the developer community.

Community Engagement: Address issues, create documentation, and develop a vision for open-source initiatives.

Fullstack Development & Technical Lead: Build robust applications using TypeScript, Nuxt3 and Vue. Collaborate with product managers to conceptualize, architect and implement projects in agile teams.

Mentor and Guide: Help junior developers level up their skills through mentoring and collaborative projects.

Open-Source Enthusiast: You have experience contributing to open-source projects and actively engaging with the community.

Craftsmanship in Code: You take pride in writing clean, composable, and peer-reviewed code that meets high-quality standards.
Passionate Collaborator: You’re excited about shaping the future of open-source and love working with others to bring ideas to life.
Hands-On Problem Solver: You’re open to a real-life coding challenge during the application process. We value developers who enjoy rolling up their sleeves and writing great code, not just technical managers.
Strong Communicator: Your can communicate great in English (and German is a bonus).
