Product Designer - Senior Level, Developer Platform

  • San Francisco, CA, USA
  • Full-time

Company Description

We believe everyone should be able to participate and thrive in the economy, so we’re building tools that make commerce easier and more accessible to all. We started with a little white credit card reader but haven’t stopped there. Our new reader helps our sellers accept chip cards and NFC payments, and our Cash app lets people pay each other back instantly. We’re empowering the independent electrician to send invoices, setting up the favorite food truck with a delivery option, and helping the ice cream shop pay its employees.
