What is Network Operations (BONS)?

Blizzard online network systems is the global network operations team responsible for supporting ALL of Blizzard’s customer-facing IT systems and services.  Such services include Battle.net, World of Warcraft, StarCraft II, Diablo 3, Hearthstone, and Heroes of the Storm.  In addition to managing these IT platforms, BONS also works closely with our development teams throughout a product’s lifecycle.  Our team’s mission statement: Innovating and delivering global technology solutions to power the most epic entertainment experience... Ever.

 
Understand your Responsibilities
 
Improve and Implement:

As a network admin you will look for opportunities to improve efficiency within the network, look for deficiencies in existing implementations, and propose solutions. In addition you will support our senior admins and engineers in the integration of complex deployments to support a global network environment. Whether day to day optimizations or analysis of complex problems, you’ll be the glue that keeps the environment running.

 
Troubleshoot and Support:

As the bread and butter of the admin team, you will resolve critical environmental outages and develop improvements and solutions to prevent such problems from reoccurring. You will work directly with vendors and peering partners in making sure the series of tubes connecting Blizzard’s services and customers are able to successfully handle enormous amounts of material. In this role you will also manage network configuration branches, provide network documentation and diagrams, and maintain network device hardware and software deployments within the environment.  As with most IT groups, you will share off-hours duties for global on-call coverage on a rotational basis.

 
Security and Stability:

Security is everyone’s job. As the core backbone of operations, you will identify security weaknesses and propose solutions that hold stability and security in the forefront. As a stalwart defender of the network, you will be principally responsible for managing stateful firewall rules and ACLs, assisting with network security audits, device patching, and educating peers and internal customers on security practices and principles.

 
Lead and Grow:

As a core member of our admin team, you will provide training sessions on complex subjects or newly evolving technologies to peers and internal customers, including upper management. In this position, you will actively engage with peers to provide consultation and recommendations, as well as develop documentation on new or old technologies and how it relates to internal systems. You will have opportunity to learn and grow in your career; working with a plethora of network protocols and technologies.

 
Technical Requirements
 
Time in the field:

This position requires a minimum of 2 years’ experience supporting a network operations group which focuses on service stability, security, and customer satisfaction.

 
The Technicalities:

Strong understanding of networking from conceptual design to physical implementation is a must, as is in-depth knowledge of the TCP / IP stack, layers of the OSI Model, network topologies, and routing protocols. Solid TCP connectivity debugging experience is part of the job, which frequently means getting dirty with packet captures or helping track down protocol bugs in embedded network operating systems. 

 
Network OS and Protocols:

Cisco IOS and the CLI should be second nature to you. You must have demonstrative experience with VLANs, STP, EtherChannel bonding and load-balancing algorithms, IPv4 Subnetting, and should know the differences between NAT and PAT (and when to use them).  In-depth knowledge of fundamental Internet standards encompassing DHCP, PXE, DNS, SMTP, SNMP, HTTP and many other services that stretch between the inter-tubes should hold a permanent slot in your array of wisdom and experience.

 
Thrive in our environment:

Our environment never stays the same. The perfect candidate should exhibit a high attention to detail, adjust quickly to an ever-changing and evolving environment, and poses sharp analytical competency for all-things-technology! We like to travel while doing IT stuff; therefore occasional domestic, and / or international travel is required.

 

A strong candidate will also bring to the table some of the following:

  • Experience with Juniper switches and routers, Linux TCP / IP stack
  • Experience with firewall appliances (Cisco ASA, FWSM) and VPN tunneling
  • Experience with routing protocols, such as OSPF, EIGRP, and BGP
  • Experience with high density multi-layer switching platforms, such as Cisco 6500, Nexus series
  • Experience with network load balancers, SSL Offloading, Cisco ACE, F5, and Citrix
  • Experience with advanced network diagnostic tools, tcpdump, Wireshark, and NetFlow
  • Experience with monitoring solutions, such as Cacti, CiscoWork, and Cisco Prime
  • Experience with network cabling, fiber optics, and enterprise data center environments
  • Network certifications, such as CCNA, CCNP, JNCIA, etc.
