Senior Full Stack Developer

Role Summary The Senior Full Stack Developer is responsible for designing, building, and maintaining software solutions that support Intellivo's case management platform modernization and client-facing applications. This role bridges legacy and modern technology stacks, executing an incremental migration from a C#/.NET thick-client desktop application and stored-procedure-driven backend to a cloud-native Azure architecture using modern front-end frameworks and API-first design patterns. This person must be fluent in both legacy WinForms/WPF patterns and modern web development to execute a strangler-fig migration strategy that keeps production stable while delivering new cloud-native capabilities. The role partners closely with Data Engineering, Infrastructure, Product, and Operations to translate business requirements into reliable, secure, and user-centered applications in a regulated healthcare environment. Core Responsibilities Full Stack Application Development Design, develop, and enhance full stack applications across both legacy and modern technology stacks. Build responsive front-end interfaces using React, Blazor, or equivalent modern frameworks alongside back-end services on Azure. Write clean, maintainable, and well-documented code aligned with engineering standards and architectural direction. Legacy-to-Modern Migration Execute incremental migration of a legacy C#/.NET WinForms/WPF desktop application to a cloud-native Azure architecture using the strangler-fig pattern. Identify stored procedures and business logic suitable for extraction into modern API services without disrupting production operations. Maintain and stabilize the legacy platform during the transition period, ensuring continuity for 75+ daily users. API and Integration Development Build and maintain RESTful APIs and services that support case management workflows, client-facing portals, and data pipeline integrations. Work with Data Engineering and DevOps to ensure stable, scalable, and secure data movement across hybrid environments (on-premises and cloud). Integrate with third-party services, reporting tools, and identity management systems as required. Code Quality and Engineering Practices Implement automated testing practices including unit, integration, and regression testing. Participate in code reviews, enforce engineering standards, and contribute to the team's definition of done. Support CI/CD pipeline adoption and infrastructure-as-code practices across the development lifecycle. Production Support and Reliability Partner with engineering and operations teams to troubleshoot issues, resolve defects, and improve system reliability. Monitor system performance and propose improvements to both legacy and modern components. Contribute to incident response and post-incident review processes. Collaboration and Stakeholder Engagement Work with Product and business stakeholders to understand requirements, contribute to technical designs, and deliver solutions aligned with roadmap priorities. Communicate technical concepts clearly to non-technical partners including operations leadership and client services teams. Mentor junior developers on engineering best practices, code quality, and modern development patterns. Qualifications Required B.S. or B.A. in Computer Science, Software Engineering, Information Systems, or a related field. 7+ years of professional full stack software development experience. Proficiency in C#/.NET with strong experience in both WinForms/WPF and modern web frameworks (React, Blazor, or equivalent). Experience building and supporting web applications, RESTful APIs, and integrated systems in production environments. Strong SQL experience including comfort with stored-procedure-driven architectures and relational database design. Experience with Azure cloud services (Azure SQL, Azure App Service, Azure Functions, or equivalent). Familiarity with CI/CD, DevOps practices, version control (Git), and automated testing frameworks. Demonstrated experience using AI-assisted development tools (e.g., GitHub Copilot, Cursor, or similar) to accelerate coding, refactoring, and code review workflows. Preferred Experience with legacy-to-modern migration patterns (strangler-fig, anti-corruption layer, or similar). Familiarity with healthcare or regulated industry application development and HIPAA compliance requirements. Exposure to Power BI embedded analytics or reporting platform integration. Experience with TypeScript, Node.js, or other complementary full stack technologies. Professional Skills Strong problem-solving ability with attention to detail and pragmatic engineering judgment. Ability to work independently while collaborating effectively across technical and business teams. Comfortable navigating ambiguity in a hybrid legacy/modern environment where not everything is documented. Demonstrated ownership and initiative in driving development tasks through completion. #J-18808-Ljbffr Intellivo
