Senior Software Engineer, Continuous Integration Infrastructure

  • San Francisco, CA
  • Full-time

Company Description

When we launched the little white reader, we invented mobile, ubiquitous payments and enabled anyone to start, run, and grow a business. Ten years and billions of transactions later we’re reimagining commerce for businesses of all types and sizes—we’re enabling the independent electrician to send invoices, helping the beauty salon pay its employees, and giving the burgeoning coffee chain capital for a second, third, and fourth location. We’re working to find new and better ways to help businesses succeed on their own terms—and we’re looking for people like you to help shape tomorrow at Square.

Job Description

The CI Infrastructure team strives to enable our engineers to test and release their applications as efficiently as possible. Our role is to design, implement, and manage a solution to lower the friction of developing in a service-oriented architecture through the use of cloud computing and container technologies like Kubernetes & methodologies such as Continuous Deployment.

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.

The team regularly works with open source projects and tools and we contribute back as well. Our main CI application, Kochiku, was built in-house and open sourced. Check out Square's full list of open source projects at http://square.github.io/.
