We are looking for a Senior .NET Developer with 8+ years of experience to build high-impact software for Swiss banking clients. This version of the role focuses on modern, Cloud-Native architectures, moving away from legacy SOAP systems toward agile, scalable RESTful services.

Messaging:
Integration of APIs with message-based middleware like NService

Bus or Rabbit

MQ.
Dev Ops Mindset:
Experience with CI/CD pipelines, Docker, and Kubernetes (as listed in preferred skills).

Key Responsibilities

API Design & Evolution:
Architecting RESTful interfaces that are secure, stateless, and easy for frontend teams (Angular

JS) to consume.

Standardization:
Using Swagger to maintain clear API contracts and facilitate "API-first" development.

Scalability:
Building asynchronous workflows and message-driven architectures for high-throughput production environments.

Security & Performance:
Implementing modern security standards (OAuth2, JWT) and fine-tuning .NET performance for banking transactions.

Collaboration:

Working in cross-functional teams (Product Owners, QA, Architects) to deliver consistent business value.

Preferred Skills (Nice to Have)

Frontend Development:

Experience with Angular

JS for building or maintaining web applications.
Cloud Platforms:
Hands-on exposure to GCP (Google Cloud), Azure, or AWS.
Containerization:
Familiarity with Kubernetes and container orchestration.
Enterprise Messaging:
Knowledge of IBM MQ (version 9.3.5.1 or similar) and its integration with .NET.
Integration Patterns:
Deep understanding of both frontend and backend integration patterns beyond standard REST.
