About the Role Our client is a well-established specialty insurance and reinsurance organization seeking a hands-on Senior Full Stack Developer to take ownership of a portfolio of mission-critical financial applications. This is a high-impact, contract-to-hire opportunity where you will step into a developer lead capacity, freeing up the Solution Architect to focus on enterprise-level initiatives. You will own delivery end to end across a modern Microsoft cloud stack, lead without formal authority, and serve as the bridge between the business and technology teams in a SOX-controlled environment. Responsibilities

• Assume full ownership of four to five priority financial applications, driving delivery from requirements through deployment and production support
• Lead the development team day to day without direct managerial authority, setting engineering standards, conducting code reviews, and maintaining accountability across the team
• Architect, build, and modernize cloud-native applications using the Microsoft Azure stack (Azure Functions, Azure Service Bus, Azure SQL, Azure Fabric, Power BI)
• Design and build Blazor front-end applications and REST API services following SOLID and clean architecture principles
• Integrate with SAP for financial data exchange across reinsurance, ledger, and transactional processing workflows
• Implement and maintain SOX-compliant SDLC controls, support PwC and internal audits, and serve as the subject matter expert for compliance-related questions on your applications
• Write complex T-SQL, optimize query plans, and design schemas for high-volume financial data workloads
• Configure and maintain observability using OpenTelemetry, Azure Monitor, Azure Insights, and Azure Alerting
• Collaborate closely with finance business stakeholders to translate domain-specific requirements (ledgers, netting, eliminations, IFRS reporting) into technical solutions
• Champion the KISS principle and pragmatic engineering practices across the team

Requirements

• 10+ years of hands-on experience across the full Microsoft stack: C#, .NET 8/10, ASP.NET Core, and Azure
• Production-level Blazor experience required; candidates must be able to walk and talk Razor/Blazor application architecture
• Demonstrated experience integrating with SAP (or comparable ERP) in a financial services or insurance environment
• Proven track record in SOX-controlled environments, including ITGC controls, audit support, SoD enforcement, and SDLC compliance
• Strong Azure cloud engineering depth: Azure Functions, Azure Service Bus, Azure SQL, Azure Fabric, Power BI; Azure DevOps CI/CD
• Expert-level T-SQL including query optimization, schema design, and stored procedures for high-volume transactional systems
• Ability to lead a small development team (3-5 developers) without direct authority, with strong soft skills and a relationship-first approach
• Experience owning the full feature lifecycle: requirements, technical design, implementation, code review, testing, deployment, and ops
• Familiarity with financial domain concepts such as general ledger, offsetting entries, netting, eliminations, and financial reporting standards
• Working knowledge of OpenTelemetry, Azure Monitor, and Azure Alerting for application observability
• Experience with .NET Aspire, microservices architecture, and clean architecture patterns a strong plus
• Insurance or financial services industry background strongly preferred
