Sr. Software Engineer

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.

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
• Performance and application performance monitoring (APM) tooling, and familiarity with security and compliance frameworks (SAST, SOC 2, or HITRUST)
• Legacy application migration and modernization experience
