About the role
Key responsibilities & impact- Design, develop, and maintain scalable backend services in Go
- Design and implement performant, idiomatic REST APIs, including interfaces to internal and external systems as well as web and mobile clients
- Take responsibility for transactional data: payments and credits without data loss, even at peak load
- Performance and error monitoring, bug fixing, and optimization of existing services regarding performance, concurrency, and resource consumption, especially SQL queries and database interfaces
- Light fullstack component: implement smaller features and adjustments in the web frontend end-to-end (Angular 21 with TypeScript, step-by-step migration from Angular Material to Tailwind CSS)
- Ensure code quality: code reviews, unit and integration tests, best practices, and adherence to existing guidelines
- Contribute to architecture decisions and the further development of our CI/CD pipeline
Requirements
What you’ll need- Ideally three to five years of professional experience in backend development; you have a strong command of Go and SQL
- Solid experience with REST and API-driven applications, from API design to consuming external APIs, for web and mobile clients
- Awareness of transactional data and the risks of data loss or outages
- You understand how LLMs and AI agents work in software development, ideally with first hands-on experience in Claude Code, Codex, or Cursor
- You master your tools, especially for debugging and performance measurement
- You write clean, tested code, work in a structured way, and communicate confidently in German or English
- Knowledge of MariaDB (GORM), InfluxDB, or comparable databases
- Nice-to-have: Production experience with Docker and Linux
- Experience on the web frontend, ideally with Angular, TypeScript, and Tailwind CSS
- First experience with webhooks, caching, and message queues (Kafka, RabbitMQ, Redis)
- Completed vocational training in IT, an IT degree, or comparable practical experience
Benefits
Comp & perks- €55,000–80,000 annual salary (depending on experience) plus equity option: you share in our success
- Real ownership: you help shape architecture decisions, and your code runs in production within days, not quarters
- Truly hybrid: remote whenever it works for you and your working model, plus regular shared days at our office in the heart of Düsseldorf
- AI-first setup: modern hardware and all the AI tools that make you more productive. Claude Code & co. are part of everyday work
- Impact over politics: lean hierarchies, results matter, speed over meetings
- Predictable time and learning budget, lunch benefit, team dinners, and shared on-/offsites
