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 youll be doing

Our engineers have experience running large, distributed systems both on bare metal and on cloud services (bonus points for Amazon Web Services.) Our systems process 500+ BILLION transactions per day! You will join a team that focuses on quality, pragmatic solutions to issues. Operating in an automation first environment, you will work along side our development team 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. Accurately. The first time.

Our Tech Stack

These are some technologies that we are using to operate and improve our platform:

• Linux (Debian)

• AWS (EC2)

• Python / Rust

• Ansible

• Nagios, Grafana

Who you are?

To join the team, we are looking for candidates with a background in Linux/BSD systems and operation at scale. Strong candidates can show skill in networking and automation, preferably with Ansible and Python experience. While it would be excellent if you already know something about the DNS, as long as you have a basic understanding and ability to learn, we are always happy to guide new team members the ropes. We also want to know that you've been responsible for time-sensitive, critically important 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 SLOs are high. You have shown all the vital skills to build and improve these systems over the course of your career -- this isnt your first rodeo.
