We're building a world of health around every individual - shaping a more connected, convenient and compassionate health experience. At CVS Health®, you'll be surrounded by passionate colleagues who care deeply, innovate with purpose, hold ourselves accountable and prioritize safety and quality in everything we do.

If you're passionate about building real, production-ready AI systems—and not just experimenting in notebooks—this role offers the opportunity to do meaningful, hands‑on work at the forefront of applied AI engineering.

• Design and develop AI-powered applications and features using Python, leveraging LLMs, RAG (Retrieval Augmented Generation), and agentic AI frameworks.
• Build and deploy production-ready AI agents and assistants that automate workflows and enhance user experiences across enterprise applications.
• Implement RAG pipelines including document ingestion, chunking strategies, vector embeddings, and semantic search to enable intelligent information retrieval.
• Develop and integrate AI features into existing applications using RESTful APIs, microservices architecture, and cloud‑native patterns.
• Apply prompt engineering best practices to optimize LLM outputs for accuracy, consistency, and reliability in production environments.
• Collaborate with software engineers, product managers, and UX designers to translate business requirements into AI‑powered solutions.
• Evaluate and select appropriate AI models, frameworks, and tools based on use case requirements, cost, and performance considerations.
• Write clean, maintainable, and well‑tested code following software engineering best practices including code reviews, CI/CD, and version control.
• Monitor AI application performance, implement logging and observability, and continuously improve model accuracy and response quality.
• Stay current on emerging AI technologies, frameworks (Lang Chain, Llama Index, CrewAI), and industry best practices in AI application development.

• 5+ years of software development experience with Python
• Experience building applications using LLMs (OpenAI, Anthropic, Azure OpenAI, or open-source models)
• Hands‑on experience with RAG (Retrieval Augmented Generation) implementations
• Familiarity with vector databases
• Experience with at least one cloud platform (AWS, Azure, or GCP)
• Proficiency in Git version control and collaborative development workflows

• Experience with Agentic AI frameworks (Lang Chain Agents, Auto Gen, CrewAI, or similar)
• Familiarity with AI‑assisted development tools and practices (Git Hub Copilot, Cursor, or similar)
• Experience with containerization (Docker) and orchestration (Kubernetes)
• Knowledge of CI/CD pipelines (Git Hub Actions, Jenkins, or similar)
• Experience with FastAPI, Flask, or similar Python web frameworks
• Familiarity with frontend technologies (React, JavaScript) for full‑stack AI applications
• Experience with prompt engineering, fine‑tuning, and model evaluation techniques
• Understanding of AI safety, responsible AI practices, and ethical considerations
• Experience with document processing libraries (Lang Chain document loaders, Unstructured, etc.)
• Familiarity with observability tools for AI applications (Lang Smith, Weights & Biases, or similar)
• Strong problem‑solving skills and ability to debug complex AI system behaviors
• Understanding of RESTful API design and integration

• Bachelor's degree in Computer Science, Software Engineering, Information Technology, or a related field is required.
• Equivalent practical experience will be considered.
