About Sidestream

At Sidestream, we’re building a team of committed, explorative and witty individuals who love pushing boundaries while having fun. Here’s what you can expect:

• 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.

Your Responsibilities

• Fullstack Development: Build robust applications using TypeScript, Nuxt3 and Vue.
• Lead Projects: 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.
• Drive Innovation: Propose and implement new technologies or methodologies to keep Sidestream at the cutting edge.

• Craftsmanship: You take pride in writing high-quality, peer-reviewed, and production-ready code that makes a real impact.
• Pragmatic Approach: You focus on doing the right things, the right way, efficiently and effectively.
• 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).

Application Tip: No cover letter required! Instead, share 2-3 sentences about why you’re excited about this role and what makes Sidestream appealing to you. You can also include links to projects you’ve worked on to give us an impression of your skills and contributions.
