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.

Our Software Engineers will keep Square simple and making our users faster and smarter by giving them a designed payments experience and rich data surrounding each transaction. We’re looking for smart engineers of all shapes and sizes, who are excited to build outstanding software and solve hard problems. Our challenges span many technologies, web and mobile applications (iOS, Android) to server-side development (Java and/or Ruby). Our engineers work on small teams with people across engineering, product, and creative, building reliable, fast, responsive, and beautiful software. 

Opportunities are available in our San Francisco and Atlanta offices (with limited roles available in our NYC office).

You will build and improve:

• Reliability: Ensure Square works right, every time, by using testing, continuous integration, and in-depth code reviews.
• Fraud Prevention: Make quick decisions on millions of dollars which requires diligence and passion for detecting bad actors and preventing loss.
• Security: Create interactions and APIs that strengthen trust, increase security, and make it harder to do the wrong thing.
• Analytics: Collect all the data around every transaction and turn it into tools that help our users.
• Products: Envision entire new products, features, and flows that are inspired, considered, and magical.

• Completing a degree in Computer Science, Electrical Engineering, Math or related technical field, with an expected graduation between December 2019 and August 2020. Bootcamp graduates and and engineering training participants are also considered upon completion of program requirements.
   
• Programming experience in one or more object-oriented languages, including C, C++, Objective-C, Java, Ruby, Scala, Go, and/or Python.
   

At Square, our purpose is to empower – within and outside of our walls. In order to build the best tools for the businesses and customers we support all over the world, we have to start at home with a workforce as diverse and empowered as our sellers. To this end, we take great care to evaluate all employees and job applicants equally, based on merit, competence, and qualifications. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, disability status, or any other characteristic protected by law. We encourage candidates from all backgrounds to apply and always consider qualified applicants with arrest and conviction records, in accordance with the San Francisco Fair Chance Ordinance.

Applicants in need of special assistance or accommodation during the interview process or in accessing our website may contact us. We will treat your request as confidentially as possible. In your email, please include your name and preferred method of contact, and we will respond as soon as possible.
