Guaranteed Rate is changing the way people buy homes. In 2015, we introduced the Digital Mortgage SM solution, enabling people to get approved for a loan online in less than 30 minutes. With our low rates and dedication to customer success, we quickly became the eighth largest retail mortgage lender in the country.

Network Engineer 

We are looking for an experienced Network Engineer to assist in maintaining our network reliability and lead improvement projects in our effort to change the mortgage industry completely! 

The Financial technology space "Fintech" space is booming and Guaranteed Rate is at the center of it. We are focused on automating the mortgage process for consumers. Imagine getting a mortgage with no email, no faxing, no stack of papers in 10 days or less instead of 30 or more!! If you have been through the process of buying a home, you know how amazing this will be. We are the #8 lender in the country and one of only 2 that is independent (not a bank) so we are in a good spot to win this race. We have already made tremendous strides and we are looking for someone who wants to help us finish the job and disrupt the entire industry.  

Who is GR?

Guaranteed Rate is not your typical company and certainly not your typical mortgage company. We are young, technology driven, have tons of energy and we love what we do – get people and great priced mortgages alongside our impeccable customer service. We’re in a River North office with exposed brick and duct work, windows we can actually open during the summer and an open floor plan – no cubicle life here. The awesomeness doesn’t end there; we also have:

  • Holiday parties? We got’em! Not just major holidays, any holiday…. Mardi Gras, Valentine’s Day, St. Paddy’s Day, Opening Day, Boxing Day (for our Canadian employee), Sweetest Day, Groundhog Day, etc.
  • Game room, library and white board paint for collaboration – yeah, it’s awesome.
  • Access to our free GR nurse practitioner. Psshh who needs a doctor’s appointment when our nurse can do it all? Did we mention the free part?
  • 401k with some matching, Blue Cross health care coverage – yup, dental and vision too, short-term disability, life insurance – we got ya covered on this one, legal assistance – for a small monthly fee.

So what do we want from you?

The position is responsible for the remediation, management and troubleshooting of Guaranteed Rate’s local and wide-area network facilities. The network is comprised of approximately 180 offices with planned growth ~50 sites of which about 90% are “on-net” using local Juniper firewalls to a Cisco VPN concentrator and 5% are on an MPLS connections moving to WAN solutions. Two active/active data centers as well as a large Amazon presence. The entire architecture is based on Cisco router and switch hardware. 

 A few other things too:

  • Maintain a fault-tolerant network to ensure a 99.9% uptime for application services.
  • Own the resolution of level 3 outages and network equipment failures meeting department service level agreements (SLAs) by involving the necessary team members and vendors where appropriate.
  • Own the establishment of a basic NOC including the improvement of the internal monitoring and alerting infrastructure.
  • Collaborates with other teams to facilitate new architectures and deployments as they relate to networking architectures including systems team and vendors to ensure application needs are met in addition to end-user needs.
  • Create and maintain internal documentation for team use as well as for NOC/Level1 support staff troubleshooting manuals.
  • Cross train team members to spread technical and institutional knowledge. If you are the only one that understands a network feature, you have failed.

What you’ll bring to the table.

  • Deep desire to create a well-running machine. Guaranteed Rate has grown significantly over the last 5 years and our network has barely kept pace. You will be the person implementing best practices to support organization growth.
  • Three or more years of experience in network engineering with at least the last two of the three in a large Cisco environment. Experience in a large retail environment a plus.
  • Experience operating/managing a large organization’s routers and switches, VLANs and wireless networks.
  • Extensive experience with troubleshooting wide-area, multi-provider networks.
