Square builds common business tools in unconventional ways so more people can start, run, and grow their businesses. When Square started, it was difficult and expensive (or just plain impossible) for some businesses to take credit cards. Square made credit card payments possible for all by turning a mobile phone into a credit card reader. Since then Square has been building an entire business toolkit of both hardware and software products including Square Capital, Square Terminal, Square Payroll, and more. 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.

As a team, we value correctness, efficiency, and safety. We measure and monitor everything, and have a culture of continuous reflection and improvement.  We aim to eliminate friction 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 a senior software engineer who shares our values and has thorough experience in managing and utilizing content delivery networks (CDN).

You will:

• Help architect, design, and implement improvements to our infrastructure and how it takes advantage of content delivery networks (CDN).
• Interface with other engineering teams
• Deliver security-related enhancements at the CDN layer
• Define standards for CDN use across Square
• Build tools that drive automation and self-service
• Support engineering in troubleshooting failures and performance issues related to CDN
• Participate in an on-call rotation covering all of the above
• Mentor team members

You have:

• 5+ years hands-on experience with CDN management
• In-depth knowledge of CDN architecture and functionality
• Solid DevOps skills
• Solid experience with open source environments
• Strong understanding of protocols like DNS, TCP, TLS and HTTP
• Strong communication and collaboration skills
• Impressive organizational skills
• A personal commitment to quality

We’re working to build a more inclusive economy where our customers have equal access to opportunity, and we strive to live by these same values in building our workplace. Square is a proud equal opportunity employer. We work hard to evaluate all employees and job applicants consistently, without regard to race, color, religion, gender, national origin, age, disability, pregnancy, gender expression or identity, sexual orientation, citizenship, or any other legally protected class.
