Description:

The Enhancing Home and Community Care (HCC) Digital Connectivity program is executing a multi-year strategy to modernize the HCC digital ecosystem, reduce dependency on the Client Help and Related Information System (CHRIS) platform, and establish the technical foundations for a future-state home care platform. Current plans require the Agency to rationalize existing CHRIS functionality and progressively decompose the platform's monolithic architecture into modular, interoperable services that can integrate with next-generation digital solutions. To support this transformation, the Agency requires the procurement of three Senior Software Developers responsible for designing, developing, enhancing, and maintaining enterprise-grade web applications and backend services. These resources require extensive experience with the Microsoft technology stack, modern web development frameworks, Azure cloud services, SQL Server, and API development. They will contribute to solution development and support the delivery of secure, scalable, and high-performing software solutions.

Responsibilities:

• Design, develop, test, deploy, and maintain enterprise applications using .NET, AngularJS, JavaScript, and related technologies.
• Develop and integrate secure REST APIs and modernize legacy .NET Framework, WCF, Windows Services, and Windows Forms applications.
• Build responsive web user interfaces and implement secure authentication using JWT/OAuth2.
• Develop high-performance, multithreaded, and asynchronous applications.
• Develop, configure, and support Azure cloud services, including App Services, Azure SQL, Storage, Event Hub, ADX, Key Vault, and monitoring solutions.
• Develop and optimize SQL Server databases, including complex queries, stored procedures, indexing, execution plans, and performance tuning.
• Perform application testing, production troubleshooting, root-cause analysis, and performance optimization across application, database, cloud, and infrastructure layers.
• Support DevOps and CI/CD processes using Azure DevOps and Git-based source control.
• Conduct code reviews and ensure high-quality, maintainable, secure, and well-documented software.
• Collaborate with architects, analysts, QA, infrastructure teams, and business stakeholders on technical design and solution delivery.
• Contribute to application modernization and migration of legacy systems to modern Azure-based platforms.

Deliverables:

• Develop functionalities per business requirements.
• Migrate applications from .NET Framework 4.x to .NET Core/.NET.
• Design, develop, and implement secure RESTful APIs.
• Develop modern Angular web front-ends and migrate existing AngularJS applications to Angular.
• Develop and optimize data access and database operations, including query and performance optimization.
• Conduct performance testing and tuning to improve application scalability, responsiveness, and reliability.
• Implement and enhance application security, including authentication, authorization, and secure API practices.
