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.ymlauthoring 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
