This Senior .NET Developer role focuses on building, maintaining, and stabilizing enterprise integrations across distributed systems using .NET and Microsoft Azure. You will deliver reliable, secure, and scalable API-based and event-driven integrations that connect enterprise platforms. Success is defined by improving production stability, quickly diagnosing integration failures, and implementing durable fixes that reduce incident recurrence.

Responsibilities:

• Develop and maintain .NET/.NET Core APIs, microservices, and integration services that support enterprise system-to-system communication.
• Design and implement event-driven integrations using Azure messaging services, including Event Grid/Event Hub patterns where appropriate.
• Build and support Azure Functions, Service Bus producers/consumers, and event processors to enable reliable asynchronous workflows.
• Troubleshoot production issues across distributed integrations, identify root causes, and implement fixes to restore and improve reliability.
• Stabilize integration pipelines by improving error handling, message processing behavior, and operational safeguards in live environments.
• Partner with technical stakeholders to refine integration approaches, improve resiliency, and reduce downtime across critical interfaces.

Required Skills:

• 8+ years of hands-on software engineering experience with C#, .NET, and .NET Core.
• Hands-on expertise delivering Azure integration solutions using Azure Functions, Service Bus, and API Management.
• Experience building and supporting REST APIs and event-based integrations using Event Grid and/or Event Hub.
• Strong experience implementing microservices and event-driven architectures in production environments.
• Demonstrated ability to diagnose, troubleshoot, and stabilize production integrations and distributed-system failures.
• Working knowledge of distributed systems concepts and messaging platforms, including delivery semantics and failure modes.

Preferred Skills:

• Experience using SQL for querying, troubleshooting, and supporting data transformation needs.
• Familiarity with CI/CD and DevOps practices to automate builds, deployments, and environment promotion.
• Experience using AI-assisted development tools to accelerate debugging, performance analysis, and issue triage.
• Ability to implement resiliency patterns such as retries, idempotency, dead-letter handling, and robust error recovery.
• Experience supporting message transformation and processing between enterprise applications and integration endpoints.
• Experience improving observability for integrations through monitoring, logging, tracing, dashboards, and actionable alerting.
