Ready to shape the future of Fintech? Join us on this journey and bring your DevOps expertise to our dynamic team!

We're building an AI-native delivery team that ships working software in days, not quarters.
We're looking for a builder who uses AI coding tools as a default workflow—Claude Code, Cursor, Replit, v0, Lovable, Bolt, or similar—and can quickly turn ideas into working products, validate them with users, and iterate fast.
This is not a Staff Engineer role. Long-term architecture and production hardening are owned by the integration engineering team. Your focus is speed, experimentation, and delivering value quickly.

What You'll Do
Build & Ship

• Build and deploy end-to-end applications using AI-native development tools.
• Work across frontend, backend, databases, and deployment.
• Ship quickly to internal teams, operations, and pilot customers.
• Iterate through rapid build → demo → learn → improve cycles.

AI-Powered Product Development

• Create LLM-powered features such as:
• AI search
• Document processing
• Summarization
• Workflow automation
• Agentic experiences

Prototype & Validate

• Apply the right level of engineering rigor for the stage.
• Move fast on experiments and prototypes.
• Know when to improve, hand off, or discard solutions.
• Document successful prototypes for production teams.

AI-First Workflow

• Use AI for coding, debugging, testing, refactoring, and documentation.
• Continuously evaluate new AI development tools.
• Maintain strong judgment over AI-generated output.

Requirements

• 4+ years of software development experience or equivalent portfolio.
• Portfolio of AI-built products shipped within the last 90 days (required).
• Daily use of AI coding assistants such as Claude Code, Cursor, or similar.
• Experience with modern web development:
• React, Vue, or similar
• Node.js, Python, or similar
• Databases and APIs
• Vercel, Railway, Supabase, or similar platforms
• Ability to distinguish between prototype-quality and production-ready solutions.

Nice to Have

• PropTech, real estate, or operations-focused product experience.
• Experience moving prototypes into production.
• German language skills.

#WeAreIn for jobs that impact everyone's life. What if your ideas could change the way the world connects, powers up, or thinks? As a Staff Embedded Software Engineer in our Research & Development team, you'll have the opportunity to merge creativity with your technical expertise by shaping the future of technology, driving groundbreaking projects, and bringing new ideas to life. Are you in?
