Company Description

Square builds common business tools in unconventional ways so more people can start, run, and grow their businesses. When Square started, it was difficult and expensive (or just plain impossible) for some businesses to take credit cards. Square made credit card payments possible for all by turning a mobile phone into a credit card reader. Since then Square has been building an entire business toolkit of both hardware and software products including Square Capital, Square Terminal, Square Payroll, and more. We’re working to find new and better ways to help businesses succeed on their own terms—and we’re looking for people like you to help shape tomorrow at Square.

Job Description

It provides the necessary components to onboard new sellers by managing identity, processing their payments, transfering funds, and providing accounting, reconciliation, and reporting in a secure and compliant way. 

We are looking for a senior front-end engineer to join the Payments Onboarding team. As part of the Payment Platform, Payments Onboarding is responsible for building the foundational components used to collect information Square needs to understand the merchants we do business with, and ensure they are able to take payments in compliance with Square's banking partners and the countries in which we operate.

  • Hold yourself, and your teammates accountable to the standards of engineering that enables Square to safely move billions of dollars in payments and allow our customers to trust us with their sensitive data


You have:

  • Natural curiosity and desire to build products that merchants depend on
