Network Operations Center (NOC) Engineer

What You’ll Do

The Cisco Umbrella (formerly OpenDNS) Network Operations Center (NOC) is responsible for Level-1 incident response and the day-to-day operations of the global infrastructure that powers the Cisco Security Cloud.

The scale and complexity of our network generates a constant stream of exciting challenges which are solved by using an evolving set of technologies.

As a NOC Engineer, you will work on a dynamic ecosystem of network routing, switching, transit, peering, VPN tunneling, DDOS mitigation, compute, virtualization and container resources.

Your typical day will vary, but this is what you will be doing :

  • Work in a regional team of NOC Engineers in a follow-the-sun model.
  • Monitor the health and performance of the systems / services and quickly and efficiently respond to incidents / alerts as they arise.
  • Investigate and resolve issues or, depending upon complexity, raise the issue to higher-level network engineers, site reliability engineers and developers.
  • Support, configuration and maintenance of all networks and infrastructures.
  • Correspond with our transit providers and peers for incident resolution and help evaluate new peering opportunities.
  • Develop and document day to day processes and create and improve runbooks from lesson learned before resolving tickets.
  • Participate in occasional on-call and be flexible to work on some weekends in a rotational model
  • Whom You’ll Work With

    Infrastructure Engineering consists of Network Engineering, Systems Engineering, Site Reliability Engineering and Security Engineering - together, we build core Internet infrastructure, security applications and distributed systems at scale.

    Our environment processes millions of DNS and Proxy requests per second, across 40 datacenters and global cloud infrastructure providers.
