Your role in the team
- You actively drive our platform transformation forward - from architecture to production code.
- You are not just an implementer, but you are shaping the path from the portal monolith to a cleanly segmented, DDD-based platform with:
- Architecture Transformation: Identify, isolate, and rebuild bounded contexts from the existing portal as standalone gRPC APIs (Clean Architecture: Presentation *Application* Domain *Infrastructure).
- Domain-Driven Design: Implement new and existing domains according to the DDD model (Aggregates, Domain Events, Ubiquitous Language).
- API Design: Design of proto-/gRPC interfaces and coordination between Bounded Contexts (including Shared Kernel types, versioning via buf).
- Platform Infrastructure: Co-develop shared infrastructure and participate in architecture decisions for the Context Map (Upstream/Downstream, Anti-Corruption Layer, Tenant/Authorization Isolation).
- Work closely with the portal/frontend team to roll out migrations gradually and without loss of functionality.
- Quality focus: Ensuring code quality and test coverage for new services from the outset.
Our expectations of you
Qualifications
- Structured, autonomous working style. You are looking for real scope for design in architectural questions and not just a pure programming role.
- Fluent in German and English.
Experience
- Several years of experience in backend development with .NET / C# as well as in working with relational databases (PostgreSQL). Knowledge of Supabase is a plus.
- Practical experience with Clean Architecture and/or Domain-Driven Design (DDD) - or a strong interest in delving deeply into these topics.
- Experience with gRPC / Protobuf or comparable API technologies (REST). Knowledge of the buf tool is advantageous.
- Understanding of microservice-/bounded-context architectures and the challenges of a monolith-to-services migration, as well as experience with Docker and CI/CD (GitLab).
What we offer
- You are involved in building the new target architecture from scratch, rather than just maintaining legacy systems.
- We are a team of 18 people with an internal development department of 5 members, regularly supported by external experts.
- A fair hybrid model with 3 days on-site in Erkelenz and 2 remote days.
- Flat hierarchies, short decision-making paths, and a team spirit based on trust and passion.
- Cutting-edge hardware (e.g., MacBook Pro) and a future-proof tech stack.
- Our office is located in the heart of Erkelenz and is easily accessible by car and public transport.
