Onboarding Manager

Numeral•San Francisco, CA

About The Position

About NumeralHQ Numeral is building the automation backbone for internet commerce — starting with the painful world of sales tax compliance. We handle everything from registration to remittance, delivering a white-glove service so e-commerce businesses can stay laser-focused on what they do best: growing their products, customers, and teams. We’re one of the fastest-growing companies from Y Combinator’s W23 batch, backed by top-tier investors including Benchmark Capital. Our team has deep roots from the early days at Stripe, Airbnb, Notion, and other breakout companies — and now we’re bringing that same level of craft, speed, and ambition to a space that’s long overdue for reinvention. Numeral is small but mighty. Growth is already borderline unmanageable — which means every hire we make now will directly shape the trajectory of the company. If you’re excited about joining as an early team member and want the kind of ownership that defines careers, we want to meet you. Mission Running an online business today means wearing a thousand hats — most of them not the reason founders started their company. Our mission is to eliminate the administrative and accounting burdens that distract businesses from doing what they love. We’ve already helped hundreds of merchants avoid the headache of building giant finance teams just to manage tax compliance. Tomorrow, we’re scaling that impact even further: building the automation layer that lets internet businesses stay nimble, compliant, and future-proof. About the role: We’re looking for an Onboarding Manager to join our growing team and build the engine that powers our customer success. Our Onboarding team serves as the face of Numeral to our newest clients, guiding them from signed contract to full deployment. Your role blends customer engagement, project management, operational execution, and strong people management — ensuring customers launch quickly and confidently on our platform and your team is able to move with speed and rigor. This is a high-impact, cross-functional role. You’ll work closely with leadership, CX and the broader Ops team, Product, and Engineering to help design scalable playbooks that can support rapid growth. You thrive in ambiguity, bring order to chaos, and love building processes from 0 to 1.
