About the Opportunity

Join a large public sector digital transformation initiative focused on modernizing critical home and community care technology. As a Senior Software Developer, you will play a key role in transforming legacy enterprise applications into scalable, cloud-enabled solutions that improve the delivery of essential services across Ontario.

Working alongside architects, business analysts, QA professionals, and development teams, you will help design and deliver secure, high-performing applications using modern Microsoft technologies. This is an opportunity to contribute to a multi-year modernization program while influencing architecture, mentoring peers, and delivering meaningful technology solutions.

What's In It for You

Work on a large-scale modernization program using the latest Microsoft and Azure technologies while helping shape the future of enterprise application development. You'll join a collaborative environment that values innovation, knowledge sharing, and continuous improvement, offering exposure to complex technical challenges and opportunities for professional growth.

Your Responsibilities

You'll design, develop, test, deploy, and maintain enterprise applications using C#, .NET Core, ASP.NET Core, Angular, JavaScript, and related technologies.

You'll modernize legacy .NET Framework, WCF, Windows Services, Windows Forms, and IIS-hosted applications by decomposing monolithic systems into modular, API-driven solutions.

You'll build secure REST APIs, implement JWT and OAuth2 authentication, and develop scalable, high-performance applications using asynchronous and multithreaded programming.

You'll develop and optimize Microsoft SQL Server databases while supporting Azure App Services, Azure SQL, Storage, Event Hub, Azure Data Explorer, Key Vault, Application Insights, and Azure Monitor.

You'll support Azure DevOps CI/CD pipelines, perform code reviews, troubleshoot production issues, and collaborate with cross-functional teams to deliver secure, maintainable software solutions.

Skills and Qualifications

10+ years of enterprise software development experience using C#, .NET Core, ASP.NET Core, and legacy ASP.NET Framework technologies.

Demonstrated experience modernizing legacy applications, designing REST APIs, and implementing secure authentication and authorization using JWT and OAuth2.

Strong experience developing Angular applications, including AngularJS migration, JavaScript, HTML, CSS, jQuery, component-based architecture, and responsive user interfaces.

Advanced Microsoft SQL Server expertise, including T-SQL, stored procedures, indexing, query optimization, execution plans, and database performance tuning.

Hands-on experience with Microsoft Azure services, Azure DevOps, Git, CI/CD pipelines, application monitoring, and cloud-native development.

Strong understanding of software architecture, Domain-Driven Design (DDD), API-first design, event-driven architecture, design patterns, Agile delivery, and secure software engineering practices.

Experience developing and supporting integrations between healthcare applications and systems.

Familiarity with HL7 standards and healthcare messaging, including troubleshooting HL7 interfaces.

Knowledge of FHIR standards, resources, APIs, and modern healthcare interoperability.

Hands-on experience developing, configuring, monitoring, and troubleshooting Mirth Connect channels and integrations is considered a strong asset.
