About the role
We are looking for a Senior Full-Stack AI Engineer to join a healthcare technology project and become the technical anchor of a small, three-person engineering team.
You will take ownership of both the AI agent architecture and the full-stack application, working closely with two other engineers. This is a hands-on senior role combining backend development, AI orchestration, system architecture, and frontend engineering.
The project focuses on building AI-powered clinical workflow automation tools that help healthcare professionals process information and prepare clinical documentation while keeping all critical decisions under human control.
What you'll do
- Design and build production-ready AI agent pipelines, including intake triage, chart retrieval, cross-referencing, flag detection, protocol matching, and preparation assembly.
- Develop and maintain AI orchestration across models such as Anthropic and OpenAI, optimizing token usage, cost, and latency.
- Build and integrate MCP (Model Context Protocol) servers and tool interfaces, ensuring secure and scope-limited access to healthcare data.
- Implement robust guardrails and human-in-the-loop review workflows. All patient-facing information and chart updates must go through the appropriate clinical approval process.
- Develop the clinician-facing application using React and TypeScript, including nurse workspaces, protocol libraries, and physician summary views.
- Build and maintain backend services using Python and FastAPI.
- Integrate with healthcare systems and EMR vendor APIs for chart retrieval and draft-only document filing.
- Establish monitoring, logging, evaluation, and testing practices for AI agents and application workflows.
- Provide technical guidance and coordinate implementation across a team of three engineers.
Requirements
- 5+ years of commercial full-stack engineering experience.
- Strong hands-on experience with Python and FastAPI.
- Solid production experience with React and TypeScript.
- Proven experience building and deploying AI agentic systems in production, including:
- Tool use and function calling.
- Multi-step agent workflows and pipelines.
- Guardrails, validation, and fail-closed mechanisms.
- LangChain, LangGraph, or equivalent frameworks.
- Practical experience building or integrating MCP servers and designing secure tool interfaces.
- Experience delivering software under HIPAA or equivalent healthcare data privacy and security requirements.
- Understanding of least-privilege access, audit logging, data protection, and secure system design.
- Experience with multi-model orchestration, including routing tasks between different LLM providers based on cost, latency, and capabilities.
- Strong architectural thinking and the ability to make technical decisions independently.
- Upper-Intermediate or higher English communication skills.
Will be a plus
- Experience with speech-to-text systems and transcript-processing pipelines.
- Production integrations with EMR systems, FHIR, or other healthcare APIs.
- Experience with local model serving, such as vLLM or Ollama.
- Familiarity with AI evaluation and monitoring tools such as LangSmith, promptfoo, or custom evaluation frameworks.
- Experience building clinical workflow automation or EMR-adjacent products.
- Understanding of clinical workflows and the importance of keeping AI-generated outputs subject to physician review.
