About the Role: As a Staff Software Engineer on Gusto Pro Integrations, you'll build and own integrations between Gusto and the third-party tools accounting firms already use to run their practice. The team maintains a growing portfolio of integrations today (including our Bookkeeping integrations), and we expect that portfolio to keep expanding as the team grows what "integrations" means for Gusto Pro.
