About the role
- You build .NET applications that run in enterprise environments.
- Your primary focus is on the backend, but you understand the whole picture.
- You translate customer requirements into architecture, have AI agents generate code, review the results critically, and deliver quality.
- You develop backend solutions with .NET and integrate them into AWS cloud architectures.
- You use AI CLI tools (Claude Code, Cursor, Gemini CLI) as a multiplier for development and testing.
- You design APIs and ensure clean integration between frontend, backend, and cloud.
- You work directly with customers on technical requirements and solution design.
- You rely on automated testing and CI/CD.
- You build prototypes by feeding ideas to AI agents and iterating on their output.
Requirements
- At least 3 years of full-stack development experience with a .NET focus
- Experience with at least one AI CLI tool (Claude Code, Cursor, Gemini CLI)
- Experience with cloud technologies (AWS preferred)
- Familiarity with Git, Docker, and CI/CD
- Ability to critically evaluate AI output and deliver enterprise-grade quality
- Fluent in German and English
Benefits
- Flexible working hours and 100% remote work
- Access to AI tools and LLM keys (provided as work tools, not as a perk)
- Real enterprise projects with ownership — products for Siemens, Deutsche Börse, Volkswagen
- Support for AWS certifications and attendance at conferences
- A team of ~30 engineers that shares knowledge instead of hoarding it
- No slide-culture — we focus on building things, not on producing presentations
