Christine Straub · Lead AI/ML Engineer · Remote / United States

Lead AI/ML Engineer building the evaluation infrastructure that makes AI agents trustworthy in production.

I design RL environments, deterministic verifiers, and benchmark tasks that test whether AI agents and LLMs actually work — then I build the production systems behind them: document intelligence pipelines, RAG, MCP-based agents, and GPU-optimized inference.

About Me

Christine Straub.

I'm Christine Straub, a Lead AI/ML Engineer specializing in AI agent evaluation and production machine learning systems. My core work is evaluation infrastructure for AI agents: RL environments, task specifications, deterministic verifiers, and benchmark tasks. I also build the production systems those evaluations protect: document intelligence, OCR/VLM extraction pipelines, RAG, AI agents and MCP tooling, computer vision, and MLOps/LLMOps. Over 9+ years I have shipped production AI/ML systems across defense, healthcare, finance, robotics, legal document workflows, and enterprise AI platforms, with open-source contributions to Unstructured, the leading open-source document intelligence toolkit.

AI systems should do more than demo well. I build for clear inputs, reliable tools, measurable behavior, strong evaluation, and graceful human review when uncertainty is high. If your team needs an AI/ML engineer for agent evaluation, document intelligence, or production ML systems, let's talk.
