• Act as the primary liaison between Tax, Engineering, and Product teams
• Contribute to taxonomy design for tax data
• Provide expert feedback on TRAM generated determinations and monitoring results
• Manage and oversee team of TRAM trainers who will collect ongoing expert feedback that will be used to finetune TRAM and build on Sphere’s data moat
