Expert Opportunity - US Tax Professional ($150/hr, up to $3k/week)

We're working with a leading foundational AI lab to find experienced US tax professionals who can help train their latest language model on corporate tax preparation and compliance tasks. We're looking for CPAs and chartered accountants who have led or managed a tax department at a large corporate and have deep hands-on experience with US tax compliance. You understand the difference between a technically correct filing and one that is optimised, you know where the common errors and risks sit in corporate tax preparation, and you can evaluate AI-generated tax work with the eye of someone who has signed off on real filings. You'll create, evaluate, and refine AI-generated work across core corporate tax workflows: preparation and review of US tax forms including 1099s and corporate returns, tax provision analysis, compliance documentation, tax risk identification, and technical tax memo writing.
