Senior Site Reliability Engineer

Job Description

Mozilla is a category of one: a global technology not-for-profit super-powered by a worldwide community of volunteers, with a mission to keep the internet a healthy public resource for all. By building great products, creating innovative technologies, and engaging people to take action, we create an outsized impact in the world. We always place people ahead of profit.

Mozilla wants you to help fight for an Internet that’s open and accessible to everyone. We fulfill that mission as both a corporation and a non-profit organization, blending technology with advocacy, policy and education.

Site Reliability Engineering treats operations as a software problem. In SRE, we flip between the fine-grained detail of application debugging to the big picture of capacity across a range of systems with a user population measured in hundreds of millions. We are responsible for our products in production. We drive reliability and performance by mastering the full depth of the stack. We see no reason for system downtime. You will have the opportunity to take on complex problems of scale while using your expertise in coding, algorithms, complexity analysis and large-scale system design. And your career will take big steps forward working with some of the best developers in the industry.

Your independence, curiosity, and willingness to try new things will be an asset, not a liability.

• Design, develop, document and deliver software to improve the availability, scalability, latency and efficiency of Mozilla's services and infrastructure.

Mozilla exists to build the Internet as a public resource accessible to all because we believe that open and free is better than closed and controlled. When you work at Mozilla, you give yourself a chance to make a difference in the lives of Web users everywhere. And you give us a chance to make a difference in your life every single day. Join us to work on the Web as the platform and help create more opportunity and innovation for everyone online.
