What You'll Do

This role is within the Collaboration Software Group (CSG) and focuses on the systems and services that provide the infrastructure on which Cisco Collaboration technologies such as WebEx, Jabber, and Spark are built.

You will primarily serve as a subject matter expert on DNS and IPAM, but also on other infrastructure services like NTP, Syslog, TACACS/Radius, Netflow, and Network Automation systems, and you’ll keep these services running well. The work will periodically require the analysis and reconciliation of data between various systems, but there is opportunity to delegate the routine parts. The greater part of the job will be continually evolving these infrastructure services, including design, development, implementation, deployment, and operation.

Roles and Responsibilities:

Primarily for DNS / IPAM (and other infrastructure services, as may be appropriate):
  • Develop and analyze performance metrics
  • Optimize performance
  • Analyze data between disparate systems, develop reconciliation plans, perform or delegate reconciliation work
  • Evolve end-to-end systems architecture to be scalable, robust, and performant
  • Serve as a 24x7 On-Call resource for these systems, along with other members of the team
For other Network Automation activities:
  • Evaluate and analyze existing systems implementations
  • Evolve legacy systems to better fit into the contemporary automation framework
  • Work with the team to develop best practices for automating service lifecycle, primarily with Cisco NSO and other internally developed workflow systems
Who You'll Work With
  • Service Owners, Developers, and Project Managers across the world within CSG
  • CSG Network Engineering and Architecture Team
  • CSG Network Operations Center
  • CSG Systems Operations Center
  • Other CSG teams as necessary to support the services
  • Occasionally: other parties within Cisco (InfoSec, Corporate IT, Sales Engineering, Technical Support)
  • Rarely: customers, directly (though usually arranged by Sales Engineering or Technical Support)
Who You Are
  • You have 10 years experience and preferably an Undergraduate or Graduate degree in Computer Science
  • An expert on the DNS and BGP protocols (and competent with other common routing and application protocols)
  • An accomplished Linux Systems Administrator
  • Knowledgeable on the use of Puppet for systems configuration management
  • An accomplished developer in C, Java, and Python.  You have read kernel source and understand it.
  • You cringe at the sight of "O(n!)"
  • You can use gdb and a core dump.
  • You understand how BGP peering can influence anycast routing, and how to fix it.
  • You ponder deep philosophical questions, like: “Source of Truth: Database or Network?”
