(Senior) Fullstack Developer

This role is a great opportunity to work end-to-end on exciting features and shape our product journey at scale. You'll collaborate closely with Product Management and Design from early concept to deployment, contributing ideas and delivering high-quality code that helps us realise our product's potential. You'll join one of our small, autonomous feature squads (3-4 engineers, 1 Product Manager, 1 Designer) where your voice matters, and where you'll have plenty of scope to learn, grow, and take on more responsibility over time., * Implement and contribute to the scoping and planning of features and capabilities along the whole software lifecycle - on top of GCP with React in the frontend, serverless express services in the backend - both in TypeScript.

• Developer Experience: Contribute to making our platform better for your fellow engineers by introducing tooling improvements, participating in refactoring efforts, and collaborating on tech stack improvements.
• Support and mentor junior engineers within your team, sharing knowledge and best practices.
• Engage with internal stakeholders - within and outside tech, contributing to technical discussions.
• Contribute to the adoption of AI within our product by staying aware of relevant capabilities and helping implement AI-driven features.
• Use and explore the potential of GenAI within Engineering to improve your own productivity and help teammates leverage these tools effectively.
• Take ownership of feature delivery and code quality within your domain., * Team Spirit: We're driven by passion, commitment, and a shared mission. Team spirit matters to us - and we make it visible: with three major team events per year, two casual monthly formats at our Hamburg HQ, and a strong recognition culture where we regularly celebrate both the big and small wins together.
• Ownership: You're encouraged to take ownership from day one. In a flat hierarchy and high-trust environment, you're empowered to make meaningful decisions and drive real impact.
• Learning & Growth: We invest in your personal and professional development through a strong feedback culture, a personal learning budget, and targeted enablement formats. Our goal is to help you unlock your full potential.
• AI Enablement: Our internal tools and workflows are AI-enabled by design. We support every team and individual in applying AI at the next level in their daily work, including getting your own ChatGPT+ license, of course.
• Tech & Tooling: You'll receive a MacBook, premium over-ear headphones, and everything else you need - from hardware to tools - to be effective in your daily doing.
• Flexibility: Whether remote, hybrid, or on-site - you work where you're at your best. Our Hamburg office at Rödingsmarkt (with a rooftop terrace) is always open, and you decide each week how often you come in. Some roles even allow for fully remote setups. And if you need a change of scenery, working abroad is always an option.
• Recharge: To ensure the needed rest, we offer 30 vacation days per year (based on a 5-day week) and Dec 24th off. We also subsidize your Urban Sports Club membership and organize internal sport meetups.
• Mobility: You can lease a "JobRad" (Bike) and get a subsidized "Deutschlandticket" or "BahnCard" for public transport to be supported in your commute.
• International Environment: We're becoming more international every month, with team members already in Italy, France, the Netherlands, and Austria - which is why English is our internal company language.
