Intern AI Engineer, Early-Career – LLM Context & Data Layer (Healthcare)

Cotiviti is seeking an early-career AI engineering intern to develop AI-powered applications that improve healthcare treatment, payment, and operations. The role focuses on building LLM context layers, data retrieval systems, semantic indexing, AI components, and governance guardrails while collaborating with data, research, product, and business teams.

What you'll do:

• SQL fundamentals - comfortable writing queries against structured data, not just describing them
• Exposure to LLM APIs (e.g., OpenAI, Azure OpenAI, Anthropic) and familiarity with one orchestration framework (LangChain, LlamaIndex, or similar)
• Git basics - comfortable with branching and reviewing code as part of a team workflow
• Experience building or designing semantic layers, knowledge graphs, or context retrieval systems (RAG pipelines); understands embedding models, chunking strategies, and retrieval optimization
• Ability to reason about data quality, duplication, and freshness - especially critical for training and maintaining embeddings
• Fetch and ingest data from live external sources (APIs and web sources) into a structured pipeline - handling formats, rate limits, and failures, not just calling a pre-built connector
• Design and build the schema and storage layer your pipeline writes to, in collaboration with data engineering, comfortable with vector storage or semantic indexing patterns
• Build and test AI components - embeddings, retrieval logic, prompts - using established patterns and tools; iterate on context relevance and accuracy
• Communicates technology-related updates and requirements to other departments and contributes to presentations for senior management
• Collaborates with research and development teams, product management, and strategic analysts to support ongoing projects
• Partners with Business Units to provide reliable intelligence, validated technology options, and insights on enterprise and industry trends
• Supports technology project teams by coordinating specific tasks, assisting with day-to-day operations, and contributing to the successful delivery of solutions

What they're looking for:

• Currently pursuing or recently completed an advanced degree in healthcare, technology, or a related field (e.g., Biomedical Informatics, Computer Science) with preference of a PhD
• Demonstrated interest or experience in AI, healthcare technology, or informatics research
• Strong foundational knowledge in generative AI model development, architectures, and vector databases
• Hands-on experience with working with Machine Learning and Deep Learning models
• Hands-on experience working with cloud services (AWS/Azure), large data sets, and building data pipelines for ML solutions
• Ability to work collaboratively and communicate effectively with cross-functional teams
• Communicating with others to exchange information
• Assessing the accuracy, neatness, and thoroughness of the work assigned
• Remaining in a stationary position, often standing or sitting for prolonged periods
• Repeating motions that may include the wrists, hands, and/or fingers
• Must be able to provide a dedicated, secure work area
• Must be able to provide high-speed internet access/connectivity and office setup and maintenance

Benefits:

• Nonexempt employees are eligible to receive overtime pay for hours worked in excess of 40 hours in a given week, or as otherwise required by applicable state law.
