Tax Operations Specialist

About Miter: Miter is on a mission to help construction and field services contractors build physical infrastructure with complete confidence. Historically, our physical economy has been forced to run on outdated, clunky on-premise legacy software built in the 1980s and 1990s. Miter is rewriting that baseline by combining applied artificial intelligence with embedded fintech payments to rebuild core HR, operational management, and financial systems from the ground up. Backed by $50M+ from top-tier institutional investors including Bessemer Venture Partners, Coatue, and Battery Ventures, Miter is one of the fastest-growing vertical SaaS solutions in the construction sector.
