• Supporting TypeScript‑based services where required
• Working closely with other senior engineers as the team scales

• Concurrency patterns, goroutines, channels, memory management
• TypeScript experience with modern frameworks such as React, Angular, Node.js or NestJS
• API design and backend service development
• Experience using Go frameworks such as Gin or Echo

Nice to have

• SQL and NoSQL databases (PostgreSQL, MySQL, MongoDB, Redis)
• Cloud platforms (AWS, GCP or Azure)
• Docker, Kubernetes and CI / CD pipelines
• Testing tools such as Jest, Mocha or Go testing packages
• Secure coding practices, OAuth, JWT, encryption
• German language skills (desirable, not essential)

This role suits a senior contractor who enjoys backend engineering, clean systems and long‑term delivery within a regulated environment.
