Software Engineer - Clinical Systems (C# / .NET)

Develop and maintain software components within the O4A - TheHub clinical microservices platform, built in C# / .NET with an Angular front end. The core of the role is hands-on back-end and full-stack engineering on live clinical workflows. As part of the platform’s roadmap, the role also contributes to AI-enabled product features - such as real-time assistant chat, LLM API integration, and document-processing pipelines - so practical familiarity with Generative AI tooling is a valued asset, not the primary requirement. This is a software engineering role, not a data science or AI research role.

Your tasks:

• Develop and maintain C# / .NET microservices within O4A - TheHub, following existing architectural conventions and preserving the reliability of live clinical workflows. Includes working with the proprietary Ark framework (FME.Ark.*) - learned on the job.
• Contribute to front-end development (Angular / TypeScript) as required, in collaboration with the Lead Front-end Engineer.
• Debug and troubleshoot issues across the microservices environment, minimising impact on clinical operations.
• Contribute to the platform’s AI-enabled features (e.g. the AI Integration microservice) under the technical guidance of the Lead Data Scientist - implementing, integrating and maintaining Generative-AI capabilities as the product roadmap evolves.
• Participate in code review and technical documentation, building shared architectural knowledge of TheHub to reduce key-person dependency.
• Collaborate with the Lead Data Scientist on solution design, translating AI/ML concepts into maintainable C# components.
• Support integration with the platform’s cloud and messaging services (Azure) for real-time and asynchronous processing.
• Support integration with the platform’s cloud and messaging services (Azure) for real-time and asynchronous processing.
• Stay current with software engineering and applied Generative-AI practices relevant to the platform, and help adopt new tooling as it matures.
• Participate in technical alignment meetings with the team and clinical stakeholders.

• Bachelor’s degree in Computer Science, Information Technology, or a related field.
• Minimum 1-2 years of professional software development with demonstrated, production-grade C# / .NET experience. Preferred range is 3-5 years, enabling faster ramp-up on the platform’s proprietary framework and clinical system complexity.
• Git source control and collaborative development workflows
• Azure DevOps / YAML CI/CD pipelines
• Docker / containerization - all services run in containers; basic familiarity required
• Azure platform services: Azure OpenAI, Azure Service Bus, Azure AI Services
• Spanish: Native or fluent (team communication)
• English: Professional proficiency (documentation and tooling)
• IT skills:
• C# / .NET 8 - required; async/await, IAsyncEnumerable<>, DI, REST APIs
• ASP.NET Core - middleware pipeline, IOptions, controller and hub patterns
• Valued (differentiators):
• Angular / TypeScript / JavaScript - front-end contribution
• SignalR - real-time streaming hub; HITL concurrency patterns
• SQL / Vertica - querying and validating clinical patient data at the terminal columnar data store
• A plus (applied AI - nice to have, not required):
• LLM API integration - Azure OpenAI / OpenAI; streaming completions, tool-calling / function-calling protocols
• Agentic AI patterns - tool registries, HITL approval flows, conversation state management
• RAG pipelines - embeddings, vector stores, retrieval
• ONNX Runtime - in-process model inference for OCR pipelines
• Agent orchestration frameworks - Semantic Kernel, LangChain, AutoGen, or equivalen
• Healthcare IT or regulated environments: a plus, not required
• Awareness of clinical data sensitivity requirements (GDPR, patient data protection)
