 Description of the network environment and name of the products that will be supported:

1.     Large transport network utilizing OSPF/ISIS, BGP, MPLS, RSVP/LDP. This physical network covers most of the geography of southern California. They have approximately 300 L3 hop locations connected via a combination of Ethernet over Fiber, some copper, some microwave and a relatively small amount of traditional TDM. The network is 98% Juniper, consisting of MX960s/MX480 (2 WAN and 2 CORE routers in each Datacenter) MX240s, SRX240s in packet mode, MX104s, ACXs, LN2600s.  There is a smattering of CTP utilized to provide Circuit Emulation over the IP network.

2.     MPLS with both LDP and (transitioning to) RSVP is utilized everywhere. Both L2 and L3 tunneling are employed. VRFs are used at endpoints to segment traffic for transport across the converged network. QOS is heavily employed to protect critical services during unexpected network load events.

3.     OSPF is the IGP used (although attempts are being made to move to ISIS but route leaking in the network is slowing that effort). OSPF to ISIS migration will be completed over the next couple of months so that Northstar can be implemented. BGP is utilized to provide the MPLS signaling services (VPLS, etc) as well as for standard external route advertisement with peers.

4.     It has an ongoing project to migrate configuration and management of the network to Junos Space. The Space applications they use are Service Now, Service Insight, Network Director and Services Activation Director.

5.     Network edge security is provided by SRX5800, SRX3600 and a smattering of smaller devices. They also use SRXs to provide access control to the data center, as well as some critical operations areas (NERC CIP). (Note this is separate from the Information Security Team at Sempra which uses primarily Palo Alto).

6.     It has two primary data centers, each employing Q-Fabric for core switching. This is a G system, utilizing QFX3500s and QFX5100 at the top of rack. Fiber Channel over Ethernet (FCOE) is transported across the fabric as well but only in MPK datacenter. RB datacenter is using ISCSI as the transport. Migration plan is in effect to move to QFX10k with NSX acting as the overlay design in both datacenters

7.     It?s LAN switching vendor is officially Brocade, however they have a large amount of EX switching infrastructure, utilizing EX3300s, 4200s, 4300s, 8200s, and 9200s, as well as the QFX line 3500s, 3600s, and 5100s.

8.     Currently It is heavily focusing their efforts in moving their backup datacenter located in Monterey Park, CA to Las Vegas, NV. That involves a lot of technological changes. Juniper PS is involved in this project to move from QFabric to QFX10k to work in conjunction with VMware NSX using MC-LAG technology between leaf and spines. DC infrastructure will be running on Nutanix and the design and implementation is on going with support from HCL America. The 2 datacenters (RB and LV) WAN will be connected via a 100G link.

 Description of the Ideal candidate's strengths and experiences:

1)  Expert level relationship management, communications skills and interpersonal skills to manage face to face communications on a daily basis with multiple levels of customer management and engineering staff across multiple departments within the host company in a responsible and professional fashion.

2)   Customer Culture is casual professional with a reporting hierarchy.
