Integration meets Innovation At Celigo, we believe integration should empower — not exhaust — innovation. As a modern Integration and Automation Platform (iPaaS), we’re on a mission to simplify how companies integrate, automate, and optimize processes. Powered by game-changing technology like runtime AI and prebuilt, mission-critical integrations, Celigo is redefining how businesses connect their world. Celigo is looking for a Senior Partner Account Manager to hunt and grow the channel partnerships that extend Celigo's reach in the market. This is a business development role at its core: you will identify which partners have the potential to build real practices around Celigo, clear whatever is in the way, and grow those relationships into durable revenue engines. What would you do if hired? Own the partner pipeline from identification to activation. You will research the market to find partners worth betting on, make the first move, and drive each relationship to a productive and active practice without waiting for someone to hand you a playbook. Build and expand partner practices by working cross-functionally with sales, marketing, and product to create joint initiatives, co-sell motions, and enablement programs that make it natural for partners to lead with Celigo. Use AI to research partner companies, surface deal and performance signals from Salesforce and partner management tools, and draft partner-facing communications faster, so your time goes toward the strategy and conversations that require human judgment. Track partnership performance through KPIs and turn the data into action. When a partner is underperforming or stuck, you will diagnose what is in the way and move to fix it, not just report the gap. Stay ahead of how the iPaaS and integration ecosystem is evolving. You will bring insights on where new categories of partners are emerging and what competitors are doing in their channel programs before leadership has to ask. Navigate conflicts and
