Job Description

Square’s purpose is economic empowerment; since the company’s beginning, we have been helping numerous people start and manage their own businesses. During the pandemic, many small businesses struggled, as they scramble to adapt to going online to reach their customers.

The Orders team has a mission to enable sellers to reach their customers anywhere, and provide a seamless experience to the customers (e.g. buy online, pickup in store) that today might only be available from much larger merchants. We have already started rolling out to a small percentage of sellers, with a goal of expanding this to all sellers. Furthermore, we strive to build an Orders platform that empowers both teams at Square and an ecosystem of third-party developers to support our sellers in this bright future ahead.

This is a massive undertaking with huge challenges. We have a wide range of sellers with many different needs, and to meet those needs, we work with many stakeholder teams at Square in navigating dependencies and intertwined technical / product ambiguities. As we scale to more sellers, we also have new obstacles to overcome on performance and reliability. The team has been growing rapidly, and that has brought its own scalability challenges, so we are re-examining our rituals to support the team.

As a backend engineer on the Orders Core API team, you will help build API solutions for our first and third-party customers that support our mission of empowering our sellers to succeed by helping them throughout their entire business lifecycle. Our API solutions need to support high-volume with low-latency and be reliable.

You will:

• Help lead the design/development of Orders API solutions that are used by first and third-party developers to interact with the orders platform
• Lead by example and help foster a culture of positivity, psychological safety, and inclusivity within the team
• Work with other engineers and PM’s across multiple teams to gather requirements, design, develop, test, launch, and maintain features
• Mentor other engineers and contribute to the direction of the team
• Provide technical expertise and guidance to other engineers (both on our team and outside of our team)
• Help maintain and improve the processes we use to manage our work
• Be excited to work in the middle of the Orders ecosystem and solve complex problems that require high availability and reliability
• Be on-call for the applications our team owns

If you share our passion for this mission, and are eager to solve these complex challenges, please reach out to us!

• 5+ years of industry experience designing and building APIs using Java or an equivalent language
