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. And make it easier for customers to shop and pay at their favorite businesses. 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 is a big practitioner of the service-oriented architecture model of software development. Our production ecosystem consists of a vast array of interdependent services. Our team's mission is to lower the friction of developing in a service-oriented architecture through the use of cloud computing and container technologies like Docker. We want to make development in a SOA-environment an efficient and pleasant experience.

You should feel at home working in and around a broad swath of technologies, and understanding the day-to-day frictions of development work your colleagues face. You'll be working with Engineers across the company to eliminate bottlenecks and develop complementary solutions that allow developers to move faster. You enjoy building new systems from the ground up as much as you love tweaking existing systems to achieve maximum performance.

You Will:

• Communicate with engineering teams to determine pain points in the development process.

• Design, develop, and deploy scalable solutions that speed up development.

• Contribute to monitoring, stability, and security of existing tools.

• Communicate technical designs in writing and in person to multiple technical audiences.

• Participate in business-hours on-call rotation for issues with CI systems.

• Build systems that impact developers day-to-day.

You have:

• 3+ years of software engineering experience

• Bachelor’s degree or relevant technical experience

• Experience working with and deploying applications in Linux containers (any of LXC, Docker, Mesos, etc)

• Solid experience and skills with the Linux/Unix command line and tools

• Experience developing in at least one of Ruby, Go, Python and/or Perl

• Proficient in unit and integration testing paradigms.
