Software Engineer, New Grad (Platform Engineering) Square
San Francisco, CA

Job Description

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.

Square's goal is to carry every transaction. Our customers expect from us the highest levels of precision, predictability, and reliability. Production Engineering builds the physical and logical infrastructure that our applications sit on; this must be a solid base that our server-side software engineers can rely on to build highly available software.

As a team, we value correctness, efficiency, and automation. We measure and monitor everything, and have a culture of continuous reflection and improvement. We aim to eliminate friction for our software engineers in production and believe that no project should be delayed due to lack of reliable infrastructure. We believe that a well designed production environment can be beautiful. We're looking for engineers who share our values, particularly those who have experience building, monitoring, and maintaining high-volume, low-latency, distributed transnational platforms.
