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, helping the ice cream shop pay its employees, and giving the burgeoning coffee chain capital for a second, third, and fourth location. Let’s shorten the distance between having an idea and making a living from it. We’re here to help sellers of all sizes start, run, and grow their business—and helping them grow their business is good business for everyone.
The API Extensibility team builds common services for our public APIs that handle millions of requests a day from Square's external developer community. We are a small and growing team with an abundance of growth and impactful opportunities.
As a software engineer on the API Extensibility team, you will own the design, creation, and maintenance of new centralized, highly scalable, and performant services that will be used by every Square public API. You will work with our teams to ensure the solutions you develop work with their systems and meet the reliability and scalability required to deliver first-in-class customer experiences. As our systems require high availability, you'll design systems to handle large system outages without impact to our customers. You'll care about performance, down to the millisecond, and know how to not only implement, but to maintain these systems. Lastly, you'll have fun working on new complex problems with accomplished engineers who are passionate about what they do.
