Senior .NET Core Engineer - High-Concurrency Microservices

As a Senior .NET Engineer, you will design, develop, and optimize highly scalable, high-performance domain-driven microservices for real-time trading applications. The role calls for advanced expertise in multi-threaded environments, asynchronous programming, and modern design patterns such as Clean Architecture and Vertical Slice Architecture. You will work with cross-functional teams in an Agile Squad to deliver secure, reliable, and efficient systems.

Key Responsibilities

• Build real-time .NET Core microservices with high scalability and performance
• Apply multithreading, async patterns, and event-driven designs (Kafka, AWS SQS)
• Optimize systems for low-latency, high-throughput trading workloads
• Ensure thread safety, fault tolerance, and efficient data stream processing
• Contribute to architectures such as Clean Architecture, Vertical Slice, and CQRS
• Align technical solutions with trading and financial business needs
• Apply robust design patterns for reliability and adaptability
• Participate in Scrum ceremonies and collaborate with the PO/SM to refine requirements
• Write maintainable, testable code using TDD, and perform code reviews
• Maintain strong unit, integration, and performance test coverage
• Implement OpenTelemetry for tracing, metrics, and logs
• Build monitoring dashboards (Prometheus, Grafana, Kibana) for full system observability

Requirements

• 5+ years of software development experience, with a strong focus on .NET Core and C#
• Deep expertise in multi-threaded and asynchronous programming, and concurrency in distributed systems
• Extensive experience designing domain-driven microservices with patterns like Clean Architecture or Vertical Slice Architecture
• Strong understanding of event-driven systems and messaging frameworks (Kafka, AWS SQS, or RabbitMQ)
• Proficiency with observability tools: OpenTelemetry, Prometheus, Grafana, and Elastic (Kibana)
• Hands-on experience with CI/CD pipelines, Docker, and Kubernetes
• Experience with Agile methodologies under Scrum
• Solid knowledge of Git and version control best practices
• Bachelor’s or Master’s degree in Computer Science, Software Engineering, or a related field
