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.
Core Technical Stack
The focus is on web-standard communication and high-performance backend systems.
* Backend & APIs: Expert-level C# and .NET 6/8+. Deep expertise in designing and implementing REST APIs.
* Documentation & DX: Proficiency in Swagger (OpenAPI) for designing, documenting, and testing endpoints to ensure seamless integration.
* Databases: Advanced SQL Server (T-SQL), stored procedures, and relational database design.
* Architecture: Mastery of Microservices, Distributed Systems, and Event-Driven patterns.
* Messaging: Integration of APIs with message-based middleware like NServiceBus or RabbitMQ.
* DevOps Mindset: Experience with CI/CD pipelines, Docker, and Kubernetes (as listed in preferred skills).
Key Responsibilities
1. API Design & Evolution: Architecting RESTful interfaces that are secure, stateless, and easy for frontend teams (AngularJS) to consume.
2. Standardization: Using Swagger to maintain clear API contracts and facilitate "API-first" development.
3. Scalability: Building asynchronous workflows and message-driven architectures for high-throughput production environments.
4. Security & Performance: Implementing modern security standards (OAuth2, JWT) and fine-tuning .NET performance for banking transactions.
5. Collaboration: Working in cross-functional teams (Product Owners, QA, Architects) to deliver consistent business value.
Preferred Skills (Nice to Have)
* Frontend Development: Experience with AngularJS 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.
