AI Engineer Intern

AI Engineering Intern — AR5 Labs

Remote | Internship

ABOUT AR5 LABS

AR5 Labs builds AI-powered automation tools for data analytics. Our flagship product, PlotStudio AI, is a desktop analytics platform where specialized AI agents collaborate through a multi-stage pipeline to deliver the kind of analysis a senior data scientist would produce, complete with code, visualizations, statistical rigor, and executive-grade narrative. Think Cursor, but for data analytics.

ABOUT THE ROLE

We're looking for an AI Engineering Intern to help build and improve the AI agent pipeline behind PlotStudio AI.

This is not a research internship. You'll work on production AI systems: prompt engineering, agent orchestration, model evaluation, and the infrastructure that makes multi-agent workflows reliable. You'll see how AI agents are actually built, tested, and shipped to real users.

You'll work directly with the founder and the AI/ML team. The codebase is small enough that your contributions will ship to production quickly, and complex enough that you'll learn how a real multi-agent system works from the inside.

If you're a student who wants to build AI systems, not just study them, this is the role.

RESPONSIBILITIES

• Help design, test, and iterate on prompts for PlotStudio's multi-agent pipeline (routing, planning, coding, interpretation agents)

• Build evaluation scripts to benchmark agent output quality across different datasets and question types

• Run experiments comparing model performance (GPT-4.1, GPT-5.1, Claude, Gemini) on specific analytical tasks

• Help improve agent self-correction logic: how the system detects errors, retries, and adjusts its approach

• Work on domain skill modules that inject specialized knowledge (finance, healthcare, econometrics) into the agent pipeline

• Build internal tooling for tracking agent accuracy, token usage, and failure modes

• Help extend the agent orchestration layer (built with LangGraph) to support new workflow types

• Document prompt versions, experiment results, and engineering decisions as you go

QUALIFICATIONS

Required:

• Currently pursuing a degree in Computer Science, Data Science, AI/ML, or a related field (rising sophomore, junior, or senior)

• Comfortable writing Python. You should be able to read, write, and debug code independently

• Basic understanding of how LLMs work: prompts, tokens, context windows, temperature

• Genuine interest in AI agents, not just chatbots. You should have an opinion on why single-prompt AI falls short for complex tasks

• Willingness to experiment, break things, and iterate quickly

• Self-directed and comfortable asking questions when you're stuck

• Able to commit 15-20 hours per week

Nice to have:

• Experience using the OpenAI API, Anthropic API, or any LLM SDK

• Familiarity with LangChain, LangGraph, CrewAI, or any agent framework

• Personal projects involving LLMs, prompt engineering, or AI agents

• Coursework in machine learning, NLP, or statistics

• Familiarity with Git and version control

• Experience with FastAPI, Flask, or any Python backend framework

• Understanding of statistical methods (regression, hypothesis testing, time series)

WHAT YOU'LL LEARN

• How a production multi-agent system is built: routing, planning, execution, self-correction, and interpretation agents working in sequence

• Prompt engineering at a level most people never see: versioned prompts, domain-aware injection, structured output parsing, and quality gates between agents

• How to evaluate AI systems beyond vibes: building benchmarks, measuring accuracy, tracking regressions across prompt versions

• How to ship AI to real users in a small, fast-moving team

WHY THIS INTERNSHIP

• You'll work on a real multi-agent AI system, not a tutorial project

• Small team means high visibility and direct mentorship from the founder

• Your work will ship to production and be used by real customers

• You'll have something concrete for your resume: "I helped build and evaluate the AI agent pipeline for a production analytics platform"

MUST HAVE

We are across the United States and Canada. Must be a citizen of either country.
