• You're a relationship-driven operator who thrives on making customers wildly successful. As our first CSM, you'll own the entire post-sale experience— from onboarding new brands to deepening relationships with our existing portfolio, identifying expansion opportunities, and building the playbooks that will define how Endless Commerce delivers value at scale. • Lead new customers from signed contract to fully live on Endless— coordinating with our product team to ensure a smooth, fast, and confidence-building launch experience. • Own the health of your book of business. Build strong relationships with key stakeholders at each brand, proactively identify risk, and drive renewals. • Deeply understand each customer's operations so you can identify where additional Endless Commerce capabilities— new channels, features, or integrations— can make their lives easier and grow our footprint. • Partner with product and marketing to keep customers informed on product updates, new capabilities, and growth opportunities that are relevant to their business. • As our founding CSM, you'll be creating things from scratch— onboarding checklists, QBR templates, health score frameworks, escalation processes. You'll set the standard for how we do CS. • Synthesize feedback from across your portfolio and bring it back to product and leadership to help us build a better platform. • Work hand-in-hand with our partnerships and marketing efforts to turn happy customers into advocates who refer new brands into our ecosystem.
