At Squarespace, we believe great relationships drive great results. We’re looking for a Customer Success Manager (CSM) who is passionate about driving growth for a portfolio of SMB commerce customers and is excited to join us in establishing a brand new customer success motion from the ground up—someone who can think strategically, act tactically, and move decisively to help our customers grow their business on Squarespace. This isn’t about stepping into an existing playbook—it’s about writing it. From day one, you’ll have the chance to shape how we engage, grow, and win with our customers. Whether your background is in customer success, account management, e-commerce, consulting, or entrepreneurship, what matters most is your drive and ability to deeply understand your customers’ businesses, craft value-realization plans, and drive measurable results for your customers. You’ll serve as the architect of success across your entire book of business, building trusted relationships and delivering impact at every touchpoint. If you’re someone who thrives on ownership, loves moving fast, and gets energized by building from the ground up, this role is your chance to leave a mark—not just on your customers’ businesses, but on the future of Customer Success at Squarespace. This is a hybrid role working from our NYC office 3 days per week. This role reports to one of our Managers, CSM.
