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.
The focus is on web‑standard communication and high‑performance backend systems.
Core Technical Stack
* 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.
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)
These skills are not mandatory but are highly valued for this specific position:
* 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.
