Senior Applied AI Engineer

CaseGuild builds the industry’s most advanced evidence reasoning platform for complex litigation, helping legal teams investigate massive document sets and surface critical facts with speed and precision.

We’re a fast growing, early-stage Seattle startup building systems at the intersection of information retrieval, machine learning, and large language models, operating at billions of tokens where accuracy and speed matter. You’ll join a small, senior team that ships production systems daily, measures everything, and iterates based on real-world performance.

This role is for a startup engineer who is data-first, evaluation-driven, and has built production systems.

You’ve spent years building ML or AI systems where success isn’t measured by demos, but by metrics, benchmarks, and real-world performance. You understand that modern LLM pipelines still require datasets, experiments, baselines, and failure analysis, and you enjoy owning that end-to-end.
