Key Responsibilities

• Lead the modernization and migration of legacy WinForms applications to React-based frontend applications and microservices architectures.
• Design, develop, and deploy cloud-native applications using Azure Kubernetes Service (AKS), Azure App Services, and Azure Functions.

• Develop, maintain, and enhance enterprise applications using React, C#, .NET Core, ASP.NET, MVC, ASP.NET WebForms, and RESTful APIs.
• Implement secure authentication and authorization using OAuth 2.0, JWT, and Azure Active Directory.
• Build and maintain integrations with SQL Server, Snowflake, and other enterprise data platforms.
• Configure, monitor, troubleshoot, and optimize application performance using Azure Monitor and related monitoring solutions.
• Evaluate architectural approaches and recommend solutions that improve scalability, availability, fault tolerance, and maintainability.
• Serve as a technical subject matter expert for asset management applications and technology platforms.
• Collaborate with architects, developers, business stakeholders, and senior leadership to define requirements and deliver technical solutions.
• Manage stakeholder expectations, communicate technical recommendations, and support key business decisions.
• Participate in technical design discussions, code reviews, troubleshooting, and continuous improvement initiatives.
• Balance multiple projects and priorities while maintaining high standards for software quality and delivery.

Required Qualifications

• 10+ years of progressive software development experience, preferably within financial services or asset management.
• Strong hands-on experience with C#, .NET Core, ASP.NET, MVC, and React.
• Experience modernizing legacy applications, including WinForms and ASP.NET WebForms, into modern web applications and microservices.
• 3+ years of Microsoft Azure development experience, including:
• Experience deploying and managing cloud-native applications using Azure Kubernetes Service (AKS).
• 5+ years of SQL development experience, including stored procedures, triggers, functions, and database optimization.
• Strong backend experience with SQL Server and Snowflake.
• 5+ years of web application development experience using .NET Core, Entity Framework, REST APIs, and related technologies.
• Experience with OAuth 2.0, JWT, Web APIs, Web Services, and secure application development.
• Strong understanding of cloud architecture, microservices, distributed systems, and application integration.
• Knowledge of high availability, fault tolerance, scalability, database design, and software architecture.
• Experience with Azure monitoring, application performance optimization, and production support.
• Excellent analytical, troubleshooting, and problem-solving skills.
• Strong communication skills and experience collaborating with technical teams, business partners, and senior stakeholders.
• Ability to work independently, manage multiple priorities, and contribute effectively in a collaborative environment.

Preferred Qualifications

• Prior experience within asset management, investment management, or financial services.
• Strong application architecture and technical design experience.
• Experience leading legacy application modernization initiatives.
• Experience migrating monolithic .NET applications to Azure-based microservices.
