The Mission As a Sr/Staff Application & AI Engineer in our AI Center of Excellence, you will be a foundational member of the team responsible for architecting, building, and scaling our Scribe platform (ScribeIQ™).

You will bridge the gap between core software engineering, generative AI, and complex healthcare data structures.

This is a high-impact role where you will lead the technical implementation of LLMs, autonomous agents, and AI-driven user experiences.

Using your expertise in TypeScript, microservices, and modern frontend frameworks, you will help set the "gold standard" for how Raintree deploys scalable AI applications across the entire organization.

Key Outcomes • Architectural Strategy: Perform a comprehensive review of the Scribe platform, mapping current data flows and identifying at least two high-impact opportunities for new AI agent or workflow integrations.

What You Bring (Competencies) • Mastery of TypeScript & Modern Web: Unrivaled proficiency in TypeScript, Node.js, and modern frontend frameworks (React, Vue, or Next.js).

You write clean, scalable, and highly maintainable code. • AI & Agentic Engineering: Proven experience integrating LLMs, orchestrating autonomous AI agents, and building complex prompt workflows (e.g., using LangChain, LlamaIndex, or Semantic Kernel).

Bonus Points • ML Fluency: Strong working knowledge of foundational ML concepts, MLOps, and Python.

Educational Background • Preferred: Bachelor’s or Master’s degree in Computer Science, Software Engineering, Computer Engineering, or a related quantitative field (e.g., Mathematics or Physics).
