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.

The Payment Connections team enables Square to move money globally by building reliable channels to payment networks and acquirers. As a Software Engineer, you will build features and applications that power Square’s global expansion. Your work will empower the coffee shop down the street and the website on the other side of the planet to focus on their primary business, not on their payments. 

You will:

• Work on a team that has its hand in projects improving payments around the globe
• Dive into the specifications and systems of the incumbent financial world and find ways to abstract them into features for Square’s modern payments platform
• Work with experienced teams across Square (including a sister team in Melbourne, Australia) to translate what’s possible into remarkable experiences for our sellers and their customers
• Manage features and integrations throughout their lifecycle, from initial design to production payments
• Manage systems that move billions of dollars, pounds, and yen every week

You have:

• A natural curiosity about how money moves and the desire to become an expert in financial systems
• A willingness to lean into understanding complex systems and how they could be better
• A Bachelor’s degree in computer science or equivalent experience

Technologies we use and teach:

• Java
• Protocols such as ISO8583 and AS2805
• Deploy code to GCP, AWS, and Square's data centers
• Guice, Guava, Protocol Buffers, gRPC, Envoy
• MySQL, Kafka, SignalFX, Spanner, Bigquery
