What You'll Do
Design realistic tax tasks: provision calculations, planning scenarios, and multi-jurisdictional questions without a single clean answer Write evaluation rubrics that capture sound tax reasoning, defensible positions, and the trade-offs behind them Review AI-generated provisions, computations, and analyses for technical accuracy and compliance Build reference solutions across direct and indirect tax that anchor how the research evaluates model output Flag where models misapply rules, miss jurisdictional nuance, or take positions that wouldn't survive review You May Be A Good Fit If 5–8+ years in tax — public accounting practice or a corporate tax function You've owned a provision or run planning across jurisdictions CPA, EA, ACA / CTA, or equivalent (preferred, not required) You can explain a position clearly enough to teach the reasoning, not just the result How Engagements Work Fully remote, part-time and flexible.
