Support Mainstay's Renovation as a Service (RaaS) operations as the primary day-to-day owner of vendor and agent communications. The Vendor Operations Specialist keeps work orders moving from assignment through completion across Slack, Helpscout, Airtable and SiteCapture. They handle routine vendor and agent questions directly, manage the RaaS inbox within SLAs, and administer scope edits, partial approvals and change orders as needed. The role is also the first point of contact for vendor escalations and on-site blockers such as access, utilities and security. By keeping Airtable accurate and following up on stalled or incomplete work orders, the Vendor Operations Specialist makes sure nothing falls through the cracks. Vendor reassignment or performance intervention goes to the Head of Partnerships & Field Operations, leaving that role free for higher-leverage work.
