It’s our mission to help all of Thumbtack scale and get more done through technology and cross-functional alignment. About the Role This role owns the Internal Platform Infrastructure program, driving the platform and integration layer that powers Thumbtack's operational teams while coordinating across IT infrastructure on identity, security, and enterprise tooling initiatives. You'll partner closely with Engineering, Security, IT, Procurement, Data, HR, and business stakeholders across Commercial Operations, Sales, Service, and Trust Safety.
