Full Stack Developer with IOT

## Full Stack Developer – IoT (.NET/C#)

**Contract | Remote | U.S. citizens only**

Build and modernize a cloud-native clinical diagnostics platform for remote monitoring of instruments used by hospitals and laboratories worldwide. You’ll contribute across IoT connectivity, edge applications, software distribution, AI agents, and full-stack development as the platform transitions from TFS, VB6, and AngularJS to AWS ECS Fargate, React 19, .NET 8, and GitHub Actions.

**Responsibilities**

- Develop MQTT, AMQP, and REST pipelines connecting diagnostic instruments to cloud services.

- Create lightweight Windows and Linux edge applets for telemetry and software update enforcement; integrate instrument protocols and support migration from the legacy stack.

- Package software installers using MSI or NSIS for connected and air-gapped instrument environments.

- Implement delta updates with rollback, version detection, and audit trails; integrate IEC 62304-aligned packaging into GitHub Actions CI/CD.

- Build and deploy AI agents with LangGraph, MCP, or LangChain, including RAG pipelines using instrument manuals and support knowledge bases.

- Develop AI tools such as code generation, pull-request bots, and test scaffolding.

- Build React 19 dashboards for alerts, consumable tracking, and update status, and develop .NET 8 or Python backend services, REST APIs, and event-driven microservices.

- Create unit, integration, and end-to-end tests to support regulated software releases.

**Required focus:** Full-stack development with IoT and Microsoft technologies, including .NET/C#.
