• DevOps: Contribute to cloud infrastructure automation using Terraform
• Data Engineering: Evolve, optimize, and maintain operational PostgreSQL data sources 
• Third-Party Integration: Integrate 3rd-party data services using event-driven patterns
• Technical Ownership: Drive features end-to-end, taking technical concepts from initial design through testing and production deployment.

About you

• Technical Breadth: Solid professional software engineering background with deep backend experience in Java or Kotlin, paired with practical experience in modern JavaScript/TypeScript and React.js
• Data & Cloud Mastery: Strong SQL skills with PostgreSQL, along with hands-on experience building on cloud-native infrastructure (AWS) using Infrastructure-as-Code (Terraform)
• Architectural Versatility: Comfortable navigating microservices, monoliths, and message-oriented/event-driven patterns (e.g., AWS SNS)
• Engineering Mindset: A champion for clean code, automated testing, CI/CD, and iterative delivery
• Communication & Collaboration: Professional working proficiency in both English and German (written and spoken) to communicate effectively across our multi-office engineering team and regional partner stakeholders
