Software Engineer III, EMR Platform

About The Role

As a Senior Software Engineer, you will own complete features across our product portfolio

— from API design through application delivery. You will contribute to event-driven

services, real-time systems, and cloud-based healthcare applications. You are expected to

bring strong technical judgment to ambiguous problems, mentor less experienced

engineers, and actively shape team quality standards.

What You'll Do

• Architect and build production-grade REST APIs with full OpenAPI spec coverage
• Design and own domain-driven services aligned to clinical workflows
• Write comprehensive test suites — unit, integration, and contract tests — and hold
  
  

the team to that standard in code review

• Build and maintain features across desktop and web-based healthcare applications,
  
  

including real-time capabilities

• Integrate with cloud services and event-driven workflows
• Own CI/CD pipeline configuration and improvements
• Collaborate with security and platform teams on authentication and secrets
  
  

management

• Instrument services for observability using structured logging and APM tooling
• Mentor Software Engineer I and II team members through code review and pairing
  
  

What We're Looking For

Required

• Experience: 5+ years of professional software development experience
• C# — advanced patterns including async/await, dependency injection
  
  

(Microsoft.Extensions.DI), SOLID principles; .NET Core for APIs and .NET

Framework for desktop

• ASP.NET Core Web API — production API development including middleware,
  
  

routing, model binding, API versioning, and OpenAPI documentation

• WPF / XAML / MVVM — multi-threaded UI patterns, Dispatcher, async/await on
  
  

the UI thread, DevExpress MVVM framework

• LLBLGen Pro ORM — entity generation, query building, schema-first data access
  
  

patterns

• TypeScript / Node.js / Express / TSOA — advanced patterns including decorators,
  
  

DI (TypeDI, reflect-metadata), and auto-generated OpenAPI specs

• SQL Server — complex query design, stored procedures, index optimization
• Real-time messaging — SignalR client-side integration, Apache ActiveMQ / Apache
  
  

NMS, event-driven patterns

• AWS — S3, Lambda, Secrets Manager; practical working knowledge of MSK/Kafka
  
  

event streaming

• Authentication — JWT bearer auth, OAuth2/OIDC, Okta integration, token lifecycle
  
  

management

• Polly resilience policies — retry, circuit-breaker, and timeout patterns for external
  
  

integrations

• Testing — NUnit + Moq (C#); Jest, Supertest, Cypress (TypeScript); contract testing
  
  

against OpenAPI specs

• CI/CD — CircleCI or equivalent; pipeline authoring, environment promotion
  
  

strategies

• Structured logging and observability — NLog, Sentry, Datadog APM
• Security fundamentals — OWASP Top 10, input validation, parameterized queries,
  
  

secrets hygiene

Nice to Have

• VB.NET reading ability — legacy PVSC_Win components remain in production
• Python — ability to contribute to AI infrastructure (FastAPI, Pydantic, AWS
  
  

Lambda)

• LaunchDarkly — server-side SDK integration, flag lifecycle management
• React / Next.js — SSR, App Router, session management with NextAuth.js
• Serverless Framework — serverless.yml authoring and deployment
• Socket.io / real-time web systems — bidirectional event handling, connection
  
  

lifecycle

• Healthcare SaaS — familiarity with PHI handling, audit logging, or HIPAA-adjacent
  
  

compliance
