Senior AI Agent Engineer – LLMs, Python, Full-Stack & Healthcare Automation

Project Overview We are looking for an experienced AI Agent Engineer to help build an AI-powered operating system for independent medical practices. The platform aims to automate and streamline patient communication, clinical documentation, patient follow-ups, and care coordination through intelligent AI agents. The ideal developer will have strong software engineering fundamentals, hands-on experience building LLM-powered applications and autonomous AI agents, and the ability to develop reliable, scalable, production-ready systems. You will take ownership of projects from concept to production, including system architecture, backend and frontend development, AI integrations, workflow automation, testing, deployment, and ongoing improvements. Key Responsibilities - Design, develop, and deploy AI agents for clinical documentation, patient communication, follow-ups, and care coordination. - Build LLM-powered workflows using OpenAI APIs or other modern AI technologies. - Develop backend services, APIs, integrations, and infrastructure to support reliable AI agent execution. - Implement agent tool calling, workflow orchestration, evaluations, monitoring, and human-in-the-loop review. - Build scalable and secure full-stack applications. - Integrate external healthcare systems and third-party services where required. - Ensure data privacy, security, reliability, and appropriate human oversight for sensitive healthcare workflows. - Collaborate directly with stakeholders to understand complex clinical workflows and translate them into practical software solutions. - Take ownership of technical architecture, implementation, deployment, and continuous product improvement. Required Skills - Strong Python development experience. - Experience building LLM-powered applications and AI agents. - Experience with OpenAI APIs, function calling/tool use, and prompt engineering. - Backend development with Django, FastAPI, or similar frameworks. - Experience developing REST APIs and integrating third-party services. - Strong understanding of PostgreSQL and database architecture. - Full-stack development experience with React, JavaScript, or TypeScript. - Experience building production-ready applications with a focus on reliability, scalability, and security. - Ability to work independently and deliver complete features from concept to production. Nice to Have - Experience with RAG, vector databases, and agent orchestration frameworks. - Experience with healthcare systems, EHR/EMR integrations, or clinical workflows. - Knowledge of HIPAA-related engineering and healthcare data privacy requirements. - Experience with asynchronous processing, Redis, background jobs, and event-driven architecture. - Familiarity with AWS, Docker, CI/CD, and cloud infrastructure. - Experience building AI-powered SaaS platforms or early-stage startup products. What We're Looking For We want an engineer who thinks beyond simply writing code. You should be comfortable understanding ambiguous problems, making practical technical decisions, designing reliable systems, and building products that solve real-world problems. We value strong ownership, clear communication, engineering quality, and the ability to use AI-assisted development tools effectively. Working Arrangement - Remote collaboration with US Pacific Time overlap. - Competitive compensation based on experience. - Flexible vacation policy. - Opportunity to contribute to product architecture and technical direction from an early stage.
