Duties & Responsibilities:Technical Requirements:
  • The .NET Evolution: 3–5 years of experience across the full .NET spectrum. You must be comfortable troubleshooting legacy ASP.NET/C# 3.5 codebases while being an expert in .NET 6/8 and latest versions of C#.
  • API Mastery: Strong experience developing and consuming both SOAP (WCF/Web Services) and RESTful APIs.
  • Messaging & Events: Proven experience with Event-Driven Architecture (EDA), specifically using RabbitMQ for asynchronous processing and service decoupling.
  • Integration: Hands-on experience (or a strong desire to master) Mulesoft Anypoint Platform for API management and system orchestration.
  • Data: Proficiency in SQL Server, including writing complex stored procedures and optimizing queries for high-transaction operational databases, updating data processes.
Core Responsibilities:
  • Legacy Maintenance: Maintain and patch existing .NET 3.5/4.x operational products, ensuring "zero-downtime" and high stability for mission-critical business functions.

  • Proven track record of migrating legacy applications (e.g., .NET 3.5/4.x Framework) to modern, cross-platform architectures (e.g., .NET 6/8/Core).
  • Hands-on experience designing and implementing Event-Driven Architectures using RabbitMQ or similar message brokers (Kafka, Azure Service Bus).
  • Deep expertise in developing and securing both RESTful APIs and legacy SOAP (WCF) services. Experience with Mulesoft Anypoint Platform for orchestration is a significant plus.
  • Strong analytical skills with the ability to "reverse engineer" undocumented legacy code and refactor it into clean, maintainable microservices.
  • Experience guiding technical discussions, performing code reviews, and collaborating with cross-functional teams (Product, Ops, and Business).
