Senior Software Engineer, Seller

Square



About the job

Company Description

Since we first opened our doors in 2009, the world of commerce has evolved immensely โ€“ and so has Square. After enabling anyone to take a payment and never miss a sale, we saw sellers stymied by disparate, outmoded products and tools that wouldnโ€™t work together. So we expanded into software and started building integrated, omnichannel solutions โ€“ to help sellers sell online, manage inventory, run a busy kitchen, book appointments, engage loyal buyers, and hire and pay staff. And across it all, weโ€™ve embedded financial services tools at the point of sale, so merchants can access a business loan and manage their cash flow all in one place.

Today, weโ€™re a partner to sellers of all sizes โ€“ large, enterprise-scale businesses with complex commerce operations, sellers just starting out, as well as merchants who began selling with Square and have grown larger over time. As our sellers scale, so do our solutions. We all grow together.

There is a massive opportunity in front of us. Weโ€™re building a business that is big, meaningful, and lasting. And we are helping sellers around the world do the same.

Job Description

As Square's business continues to experience growth, these teams serve the heart of the business, allowing Square product teams and third parties to build safe, scalable, and reliable products. We are looking for software engineers who feel comfortable in all parts of the stack to join our seller organization. Here are just a few of our teams:

Payments

  • We provide APIs for first and third parties to access our platform.
  • We move money between customers, credit card processors, and banks quickly, reliably, and securely โ€“ and our ambition is to make this easy.
  • We solve several technical challenges: Security and privacy, monitoring, re-architecting for the future, scalability, supporting payment methods such as cryptocurrency, 3DS, ACH, and support Square's expansion to support new payment types in international markets.
  • We are a backend service team, and use Java on Square's Linux servers and cloud platforms along with technologies like Guice, Guava, Protocol Buffers, jOOQ, MySQL, Kafka, AWS and GCP.
Catalog
  • The Catalog team builds the platform and product features that allow Square merchants to manage the items and inventory they sell.
  • We support all types of merchants from food trucks with just a few menu items to retail chains with hundreds of thousands of SKUs for sale across many locations.
  • The team is involved in the technical details of building available and reliable services, while also working with product teams to allow Square to build new capabilities for our merchants and buyers all over the world.
  • We partner with external developers to build public APIs that allow Square to expand its ecosystem.
Prices
  • The Prices team manages tools that help Square merchants set prices, manage taxes, and provide discounts to their customers.
  • We are a full-stack team, delivering features through Mobile, Web, and API across nearly all of Squareโ€™s products.

  • We use Java / Kotlin on Android, Objective-C / Swift on iOS, Javascript and Ember on the web, and Java and Ruby on the server.
Orders
  • We are a team that ties together many software components across Square, including Payments, Prices and Catalog, allowing developers to quickly combine all components to develop new features on top of Squareโ€™s platform.
  • Our Order Platform APIs are designed for use by first (internal) and third-party (external) developers.
  • We design high-volume, low-latency, distributed transaction processing systems, making thoughtful tradeoffs between consistency and availability when both are not possible.
  • Our work spans client and server environments and we use Java, Go, Javascript and Ember.JS.
