Global Seller Onboarding Manager (West)

Since we opened our doors in 2009, the world of commerce has evolved immensely, and so has Square. After enabling anyone to take payments and never miss a sale, we saw sellers stymied by disparate, outmoded products and tools that wouldn't work together.

So we expanded into software and started building integrated, omnichannel solutions – to help sellers sell online, manage inventory, offer buy now, pay later functionality, book appointments, engage loyal buyers, and hire and pay staff. Across it all, we've embedded financial services tools at the point of sale, so merchants can access a business loan and manage their cash flow in one place. Afterpay furthers our goal to provide omnichannel tools that unlock meaningful value and growth, enabling sellers to capture the next generation shopper, increase order sizes, and compete at a larger scale.

Today, we are a partner to sellers of all sizes – large, enterprise-scale businesses with complex operations, sellers just starting, as well as merchants who began selling with Square and have grown larger over time. As our sellers grow, so do our solutions. There is a massive opportunity in front of us. We're building a significant, meaningful, and lasting business, and we are helping sellers worldwide do the same.

The Role

At Square, we believe every seller deserves an exceptional start to their journey. The Global Seller Onboarding (GSO) team is responsible for the seamless implementation of new sellers across diverse industries. We partner closely with internal teams and trusted third-party contractors to ensure every implementation—whether remote or onsite—sets the foundation for long-term success.

As we evolve our structure to better support our sellers, we're looking for a Regional Implementation Manager to lead our West Region team of Implementation Specialists (ISs). You'll play a critical leadership role in shaping how Square delivers onboarding experiences at scale, managing a high-performing internal team and supporting our broader transition to a regionally split model (East/West).

You will report directly into the temporary GSO team lead, with potential for broader leadership scope as the team structure evolves.

• Partner with cross-functional teams (e.g., Sales, Product, Support, and Legal) to resolve implementation challenges and enhance the onboarding journey.


• Champion the transition to a new East/West regional model, clearly communicating the rationale and rollout plan to internal and external stakeholders.


• Be a trusted voice and feedback loop to inform long-term organizational design and leadership planning.


• Promote an environment of trust and collaboration throughout the deal process to enable strong AE and GSO working relationships.


• Act as a change agent in the shift to regionalized onboarding, building team resilience and fostering clarity through evolving roles, workflows, and ownership models.
