Sr. Software Engineer

Duties:

You will develop end-to-end features for our healthcare portal applications, working across the full technology stack from database to user interface. Our platform is modern and actively evolving, and this role is focused on new development: building data-rich, user-facing features in a regulated healthcare environment, increasingly with AI-assisted capabilities.

The majority of your time will go to feature development for roadmap deliveries: creating lo-fi/hi-fi mockups for new features, implementing Angular components, building C# backend services, designing database schemas, and integrating with external systems. The balance goes to keeping the platform healthy as it evolves, including performance optimization, addressing technical debt, refactoring legacy patterns as our architecture modernizes, and scalability improvements.

You will work independently to translate business requirements into user interface designs and technical implementations, collaborate with other engineers on API contracts, and participate in architecture discussions. Where it fits, you will build configurable, data-driven feature logic so product behavior can be adapted without code changes, rather than one-off hard-coded flows. This position requires versatility to context-switch between frontend and backend work while maintaining code quality and adhering to healthcare compliance requirements, including writing secure, privacy-conscious code and contributing to automated testing. You'll need to navigate ambiguous requirements, proactively communicate blockers, and bring innovative ideas to improve both user experience and technical architecture.

Skills:

Required:

7+ years of full-stack software development experience with C# and a modern component-based JavaScript framework

Expert-level C# with ASP.NET Core for backend API development and business logic

Expert-level Angular and TypeScript for frontend development

Strong experience designing and consuming RESTful APIs

Solid Entity Framework Core and SQL Server skills, with comfort dropping to hand-written SQL (for example, Dapper) when performance calls for it

Experience building data-driven, configurable feature logic (rules engines or similarly parameterized behavior) rather than one-off hard-coded flows

Experience building data-forward interfaces such as dashboards, reporting, or search and filtering over sizable datasets

Proficiency in modern frontend technologies including HTML5, CSS/SCSS, and responsive design principles

Hands-on experience building and operating applications on Microsoft Azure: App Services, Azure Functions, Key Vault, and Application Insights; authentication with Azure AD B2C and MSAL; and Azure DevOps for CI/CD

A security-conscious approach to code, and experience meeting quality and application-security standards in a regulated or enterprise setting

Able to work independently and deliver with limited day-to-day direction

Strong communication skills with ability to work effectively with both technical and non-technical stakeholders

Comfortable working in environments with ambiguity and evolving requirements

Proactive problem-solver who surfaces blockers early and drives solutions

Collaborative team player who brings innovative ideas for features and technical improvements Preferred:

Healthcare or clinical application development in a HIPAA-regulated, PHI-handling environment

Integrating AI or LLM-backed capabilities with attention to grounding, citation, or explainability

Clinical decision support, guideline- or protocol-driven logic, or other rules-based domain modeling

Multi-tenant SaaS and tenant data isolation

Component-driven frontend architecture, and third-party or vendor data integrations

Experience with patient portal or member-facing applications
