• Turn product and design direction into reliable, polished mobile UX

Nice to have:

• Experience with native iOS or Android development
• Experience mentoring other developers
• Experience in small teams with high ownership

How we work:

We are a small team of highly skilled individuals, so every developer has meaningful impact. We value ownership, thoughtful communication, and steady improvement over heavy process. We care about understanding before changing. That means we prefer developers who first learn the product, the users, and the existing architecture before proposing major rewrites. We also work with modern AI-assisted development workflows. We expect you to use AI tools as leverage, while still bringing your own engineering judgment, critical thinking, and responsibility for the final result.

What we offer:

• A welcoming, open culture: We are a friendly group of people who enjoy working together. We prioritize straightforward communication, helping each other out, and solving problems without ego or politics.
• High impact: As part of a small team, your work directly shapes the product and the company.
• Meaningful product: We build something our users genuinely care about and love using.
• Remote-first flexibility: Our engineering team is remote-first. You can work fully remotely, or use our Hamburg office if you prefer. We value independent work but come together regularly for team events to connect and have fun.

Unsere Tech-Stack:

• Web: Next.js
• Mobile: React Native mit Kotlin und Swift Anpassungen
• Backend und Infrastruktur: PHP, Python, JavaScript, AWS
