US Sales & Use Tax Manager

Volta is the category-defining, fully vertically integrated AI infrastructure platform – from capital to clusters to software, under a founder-led enterprise. Our mission is The Utility of Compute™: AI infrastructure as dependable and available as electricity, for every organization that needs it. Launched with a $10B strategic partnership with one of the leading frontier AI labs, a Series A led by Andreessen Horowitz, and a $5B AI Infrastructure Fund, Volta is building the infrastructure layer of the AI era from the ground up.

We are 100+ people across London, Palo Alto, and New York, with rapid growth expectations to hundreds.

This is an opportunity for an experienced sales and use tax specialist to build scalable processes within a fast-growing, global AI infrastructure business and directly influence the tax cost of major infrastructure investments.
