• Contribute to architectures (Clean Architecture, Vertical Slice, CQRS).
• Align technical solutions with trading/financial business needs.
• Apply robust design patterns for reliability and adaptability.
• Participate in Scrum ceremonies and Agile workflows.
• Collaborate with PO/SM to refine requirements and deliver quality software.
• Write maintainable, testable code with TDD; perform code reviews.
• Maintain strong unit, integration, and performance test coverage.
• Implement OpenTelemetry for tracing, metrics, and logs.
• Ensure full system observability and actionable performance insights.

Required Expertise:

• 5+ years of experience in software development, with a strong focus on .NET Core and C#.
• Deep expertise in multi-threaded programming, asynchronous programming, and handling concurrency in distributed systems.
• Exposure to AI-assisted development tools (e.g., Claude, GitHub Copilot/Codex, Cursor) to accelerate coding, refactoring, and testing workflows.
• Extensive experience in designing and implementing domain-driven microservices with advanced architectural patterns like Clean Architecture or Vertical Slice Architecture.
• Strong understanding of event-driven systems, with knowledge of messaging frameworks such as Kafka, AWS SQS, or RabbitMQ.
• Proficiency in observability tools, including OpenTelemetry, Prometheus, Grafana, and Elastic (Kibana).
• Hands-on experience with CI/CD pipelines, containerization using Docker, and orchestration tools like Kubernetes.
• Expertise in Agile methodologies under Scrum practices.
• Solid knowledge of Git and version control best practices.

Beneficial Skills:

• Familiarity with Saga patterns for managing distributed transactions.
• Experience in trading or financial systems, particularly with low-latency, high-concurrency environments.
• Advanced database optimization skills for relational databases such as SQL Server.
