A major German bank is building out a new engineering capability and has made a request for senior GoLang contractors to help form the core of the team.

This is a long‑term, stable programme focused on building and scaling backend services used across critical banking platforms. The work is engineering‑led, well scoped, and designed for contractors who want consistency rather than constant churn.

• Designing and building backend services using GoLang
• Writing clean, performant concurrent code using goroutines and channels
• Developing and maintaining RESTful and GraphQL APIs
• Supporting TypeScript‑based services where required
• Working closely with other senior engineers as the team scales

Must have experience

• Strong commercial experience with GoLang
• 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.
