• 10–15+ years of professional experience with extensive work in C# and .NET.
• Strong experience with gRPC and cloud-based service architectures.
• Expertise with distributed messaging and event-streaming technologies including Kafka, RabbitMQ, and Redis.
• Strong understanding of backend fundamentals including high-volume message processing, interprocess communication patterns, and database performance.
• Experience building multi-tenant, event-driven B2B systems requiring millisecond-level updates.
• Experience building frameworks or shared service layers.
• Strong interest in clean architecture and high engineering standards.

Non-Technical Requirements:

• Strong analytical and architectural reasoning.
• High ownership mindset with strong follow-through and initiative.
• Ability to work independently and collaborate effectively.
