Who we are

At Cisco Umbrella (nee OpenDNS) we provide best-in-class DNS based services globally to internal and external customers. As part of Cloud Infrastructure Engineering we build DNS as infrastructure, offer network security services and operate as a business within Cisco. By working in lock-step with engineering, we enable businesses to securely innovate and protect them from existing and emerging threats.

What you’ll be doing

We are looking for engineers with experience running large, distributed systems both on bare metal and on cloud services (bonus points for Amazon Web Services.)  Our systems process 250+ BILLION transactions per day.  You will work along side our current development, system engineering, and performance teams to understand the current architecture and moving pieces.  We own these applications end-to-end; architecture, software development, infrastructure and the operational component.  The challenges can be significant. At times, it may mean rewriting or refactoring of an application in order to automate everything and remove human dependency.

We are committed to getting it done... properly, the first time.

Who you are

To join the team, you are going to want a background in Linux/BSD systems and operation.  While it would be great if you already know something about the DNS, as long as you have a basic understanding and willingness to learn, we are always happy to teach new team members the ropes.  We also want to know that you've been responsible for time sensitive, mission critical systems with a high attention to detail. Our services are the heart of the Cisco Umbrella product and we take ownership of that very seriously -- our internal and external SLOs are high.  You have demonstrated all the necessary skills to build and run these systems over the course of your career -- this isn’t your first rodeo.
