Senior Software Engineer (Server), Invoices

  • Full-time

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

Our customers rely on our products because they are well designed, easy to use, and integrated with their business. We are a full-stack product oriented team, spanning across engineering, design, product, and marketing. You'll have a seat at the table in roadmap and strategy decisions and will play a critical role in helping the team accomplish our industry leading growth goals.

Our team is focused, fast-moving, and rapidly growing with an abundance of growth and impact opportunities.
