Mid-Level Developer (.NET & Azure Integration)

Job Description

Contract Duration: 12 months

Contract details: B2B/ PFA or SRL

Location: Remote (EU-based candidates)

Role Summary

As a Mid-Level Developer, you will build and support .NET-based APIs and integrations on Azure, connecting digital journeys and workflow/case tooling to core claims systems and third-party services. Your mission is to deliver production-grade integrations for fast-track claims initiatives—such as digital FNOL, email intake, coverage checks, and fraud workflows—with a relentless focus on reliability, security, and operability.

Key Responsibilities

API Development & Management

• Build & Maintain: Develop C#/.NET (ASP.NET Core) APIs with well-defined OpenAPI/Swagger contracts, versioning, and consistent error handling.
• Azure APIM: Design, secure, and monitor APIs using Azure API Management (APIM), including the implementation of API policies, throttling, and access controls.
• Transformation: Build robust transformation and mapping logic (JSON, XML, XSLT) to integrate diverse enterprise systems and handle complex payloads.

Integration & Workflow Automation

• Logic Apps & Functions: Implement orchestration using Azure Logic Apps and develop Azure Functions (C#, JavaScript, or Python) for event handlers and integration logic.
• Asynchronous Messaging: Utilize Azure Service Bus (queues, topics, sessions) while implementing retries, dead-lettering, idempotency, and correlation.
• Event-Driven Design: Build streaming and event-driven integrations using Azure Event Grid and Azure Event Hubs.

Security, Networking & Operations

• Security: Implement secure solutions using OAuth2, Microsoft Entra ID (Azure AD), Managed Identities, and APIM policy enforcement.
• Networking: Apply Azure networking fundamentals, including VNETs, private endpoints, and firewalls, to secure connectivity patterns.
• Observability: Operate what you build by troubleshooting with Azure Monitor, Application Insights, Log Analytics, and distributed tracing.

Required Skills & Experience

Technical Core

• Development: Strong hands-on experience in C#/.NET (preferably .NET 6+) and ASP.NET Core.
• Azure Integration Services (AIS): Practical experience with APIM, Logic Apps, Azure Functions, and Service Bus messaging patterns.
• Events & Streams: Working knowledge of Event Grid and Event Hubs, with an understanding of when to use each.
• Data Handling: Proficiency with JSON/XML/XSLT transformation and mapping patterns.

Soft Skills & Mindset

• Operational Mindset: A solid troubleshooting approach using Azure observability tooling.
• Problem Solving: Comfortable dealing with "messy" real-world payloads and modernizing legacy integrations (e.g., SOAP to REST).

Certifications & Preferences

• Preferred: AZ-204 (Azure Developer Associate).
• Desirable: AZ-400 (DevOps Engineer Expert).
• Nice to Have: Familiarity with the Claims/Insurance domain (FNOL, fraud, coverage decisions) or low-code platform integration.

What Success Looks Like (First 3–6 Months)

• Stability: You have delivered 2–3 production-grade integrations that are stable, observable, and supportable.
• Governance: APIs are consistently governed through APIM (security, policies, monitoring) without exceptions.
• Resilience: Failures are handled predictably via automated retries and Dead Letter Queues (DLQs), ensuring high system availability.
