This role will lead the team responsible for administering IT-deployed, company-wide applications; building and maintaining integrations — primarily through our IPaaS platform, Workato, and, where needed, custom middleware built on AWS; and designing and deploying AI agents across our AI platform stack (Glean, Claude, Gemini, and/or AWS Bedrock) to automate and enable work across GTM, Finance, Legal, Engineering, and other teams. The ideal candidate brings strong technical breadth across applications, integration architecture, and AI enablement, along with the ability to partner effectively across every department in a fast-growing organization. By strengthening our BizApps function, this role will directly enable business scalability, operational efficiency, and cross-functional productivity.
