Senior .NET / Azure Developer - Healthcare Software

About the role

We are seeking an experienced Senior .NET Application Developer to join a small, collaborative software team supporting and enhancing business-critical healthcare applications. This position will begin as a part-time opportunity of approximately 20 hours per week with defined working hours. As the product, team, and business needs evolve, there is potential for the position to expand into a full-time opportunity and potentially convert to direct hire. This is first and foremost a hands-on software development position. We are looking for a senior developer with strong Microsoft-stack experience who can quickly become productive in an established application environment using C#, .NET, Blazor, SQL Server, JavaScript, Microsoft Azure, and Azure DevOps. Prior experience developing or supporting healthcare, medical, clinical, health insurance, pharmaceutical, EMR/EHR, or related healthcare software is highly valued. The right person will be comfortable joining an established product, learning the existing architecture before recommending changes, independently owning assigned development work, and collaborating closely with an experienced Technical Lead/Senior Developer.

Responsibilities

• Design, develop, enhance, troubleshoot, and support established web applications using C#, .NET, Blazor/Razor, JavaScript, HTML/CSS, and SQL Server.
• Develop new application functionality while maintaining and improving existing production systems.
• Work with modern .NET/ASP.NET Core as well as established Microsoft application architectures.
• Develop and optimize T-SQL, stored procedures, tables, indexes, views, and data-access logic.
• Build and maintain APIs, integrations, application services, and supporting backend functionality.
• Diagnose application and performance problems across the UI, application/service, database, integration, and cloud layers.
• Write automated tests and validate application changes before release.
• Participate in code reviews and contribute ideas for improving application design, maintainability, performance, security, and development practices.
• Manage code through Git and Azure DevOps, including branches, pull requests, builds, and application deployments.
• Work within Microsoft Azure and become increasingly familiar with the configuration and deployment of the Azure resources supporting the application.
• As you become familiar with the product and infrastructure, serve as a backup to the Technical Lead/Senior Developer for selected Azure configuration, CI/CD, deployment, and production-support responsibilities.
• Initially focus on well-defined development tasks and tickets while learning the product; over time, contribute to new tool design, feature improvements, technical direction, and UI recommendations.
• Communicate technical recommendations, risks, trade-offs, and progress clearly to both technical and non-technical team members.

Requirements

• 5+ years of professional software development experience, with significant hands-on experience in the Microsoft/.NET technology stack.
• Strong current development experience with C# and .NET / ASP.NET Core.
• Experience developing Microsoft web applications using Blazor and/or strong Razor-based development experience.
• Strong SQL Server and T-SQL development skills, including stored procedures, queries, database objects, troubleshooting, and performance optimization.
• Experience developing, enhancing, and supporting established production applications, not exclusively greenfield development.
• Prior experience developing or supporting healthcare, medical, pharmaceutical, health insurance, clinical, EMR/EHR, or other healthcare-related software.
• Hands-on experience with Microsoft Azure in an application-development environment.
• Experience with Azure DevOps, Git, CI/CD, build/release processes, and application deployments.
• Strong debugging, root-cause analysis, and production-troubleshooting skills.
• Experience with automated testing and sound object-oriented development practices.
• Ability to work independently while also collaborating closely with another highly experienced senior developer.
• Strong communication skills and the confidence to offer ideas, explain technical decisions, and respectfully challenge an approach when appropriate.
• Ability to consistently commit to the required approximately 20-hour-per-week schedule and defined working hours.
• Comfortable working beyond the code itself in the Azure environment (Azure App Services, Azure SQL, Entra ID / Azure AD, RBAC, Key Vault / secrets and application configuration, Azure Functions, application/environment configuration, CI/CD pipelines, deployment and release troubleshooting, monitoring and production diagnostics).
• Infrastructure as Code experience
