Your Mission: Your job is to make sure every TMC that launches actually performs: that its agents are trained and using the tool, its corporate accounts are migrating on schedule, and bookings are happening on Engine. You’ll be the primary relationship owner for a portfolio of TMCs and their key corporate accounts, the first call when something goes wrong, and the person who turns a quiet launch into a growing partnership. What You’ll Do: • Own post-launch success for a portfolio of TMC partners and their corporate accounts, from first booking through sustained GBV growth on Engine content • Partner with the Implementation Manager from contract signature through launch: own the commercial and relationship track while Implementation owns configuration, agent training, and first booking • Define a corporate-account migration plan and activation milestones with each TMC, hold both sides accountable to them, and own the handoff from Implementation to ongoing success management • Monitor TMC health across trips booked, lodging attached to Engine content, agent and traveler adoption, account migration pace, and support volume; flag risks and act before they compound • Lead QBRs for strategic TMCs and regular health check-ins for smaller agencies, and use them to set the next quarter’s plan with each partner • Serve as the first line of escalation for post-launch TMC issues, coordinating with Implementation, Support, and Product to drive resolution • Identify expansion within each TMC’s footprint (additional corporate accounts, air and car on Engine content, Groups and Engine X) and co-sell in partnership with the Business Development team • Bring TMC and agent feedback to Product and Implementation; you speak for the live TMC base internally What You'll Bring to Engine: • 8+ years in partner success, customer success, or strategic account management, ideally in corporate travel, TMC or booking-tool products, or B2B SaaS • Track record of managing a portfolio of B2B relationships with measurable revenue or GBV outcomes • Experience working alongside or coordinating with implementation or technical teams without owning the implementation yourself • Strong data orientation: you use metrics to diagnose problems and steer partner conversations • Strong communicator, written, verbal, and async: you can boil a complex partner situation down to a clear update for your VP • Comfortable structuring your own work without much direction Preferred • Prior experience at, or selling into, a TMC: you understand how agencies make money, how they work with GDSs, and what it takes to move a corporate account onto a new booking tool • Familiarity with corporate booking tools, GDS content, or hotel distribution • Experience building or contributing to health scoring models, QBR frameworks, or pa
