About Themis Intelligence Themis Intelligence builds the Utility Knowledge Base (UKB) and Human-Guided Intelligence (HGI) platforms, redefining how utilities operate. Our systems transform complex operational data into clear, high-confidence decisions. We design software that empowers grid professionals to think faster, act decisively, and operate with precision in critical environments. Every product we ship is built for real-world performance: reliable, observable, and secure from day one. We are an AI-first organization, continuously applying modern tools and workflows to improve how we plan, execute, and deliver outcomes.

About the Role
As an AI Engineer – Co-op at Themis Intelligence, you will help develop, evaluate, and improve the AI agents powering our intelligent applications and platforms. You'll work on real engineering challenges involving Large Language Models (LLMs), agentic workflows, and the reliability of AI-driven systems. In this role, you will
• Develop, test, and improve LLM-powered agents and agentic workflows using Python and TypeScript.
• Evaluate agent performance across accuracy, factual consistency, hallucination, reasoning, and tool-use correctness.
• Experiment with prompting techniques, retrieval strategies, and model configurations to improve response quality.
• Build and maintain automated evaluation pipelines, test datasets, and reproducible benchmarks.
• Investigate agent failures, identify root causes, and implement improvements to grounding and reliability.
• Contribute to Retrieval-Augmented Generation (RAG), semantic search,



and knowledge retrieval workflows.
• Analyze and visualize evaluation results to compare models, track improvements, and identify performance trade-offs.
• Collaborate through Git-based development, code reviews, and technical discussions while taking ownership of assigned deliverables. You might thrive in this role if you
• Currently pursuing a degree in Computer Science, Engineering, Mathematics, Physics, or a related discipline.
• Strong programming skills in Python and TypeScript, with an understanding of software development fundamentals.
• Foundational knowledge of machine learning, natural language processing, or Large Language Models (LLMs).
• Experience building software or AI-related projects through coursework, research, internships, or personal initiatives.
• Familiarity with LLM APIs, prompt engineering, or AI-assisted development tools.
• Ability to debug systematically, analyze model outputs, and evaluate results critically.
• Strong problem-solving skills, willingness to learn unfamiliar technologies, and ability to work independently with guidance.
• Ability to thrive in a fast-paced, lean team environment, adapt to evolving priorities,



and take initiative with minimal supervision. Nice to Have
• Experience with agentic frameworks such as LangGraph or similar technologies.
• Familiarity with LLM benchmarks and evaluation frameworks.
• Exposure to vector databases, embeddings, semantic search, and RAG architectures.
• Experience with tool calling, structured outputs, agent orchestration, or multi-agent systems.
• Interest in AI safety, model reliability, interpretability, and real-world AI applications. This is a 12-month duration COOP/ Intern hybrid role (four days in-office) reporting directly to the Technology Director. The salary range for this role is $20–$30 per hours.
