Network Engineer

Chicago, IL

Post Date: 08/15/2017 Job ID: 9395 Category: Network/Systems

Our Client is looking for a mid- to senior-level Network Engineer, who is passionate about all aspects of networking and gets a thrill out of designing, implementing and supporting high-performance networks.

 

You are a highly capable engineer with an appetite for accuracy, and are not afraid to go beyond the standard text-book concepts of networking. You thrive on working with your peers and cross-functional teams and are able to motivate and encourage your colleagues around you. Ability to clearly communicate - both verbally and written - technical concepts and challenges to both technical and non-technical stakeholders is a must.

 

The Network Engineers in the Trading Infrastructure team are responsible for designing, implementing and supporting the WAN, LANs and all low-latency connectivity to trading venues. They work closely with our Systems Engineers, other teams and external parties to provide best in class infrastructure solutions supporting our trading business.

 

RESPONSIBILITIES
  • Design, implement and support the European networking infrastructure. Key areas include Low-latency networking, Unicast and Multicast routing, OSPF, BGP, PIM SM, as well as things like QoS, STP, NAT, protocol tuning, etc.
  • Monitor, guard and analyze the proper functioning of our network infrastructure. Take adaptive, retentive and corrective measures and perform structural maintenance.
    Proactively improve their infrastructure by contributing scripts and code to our automation efforts (e.g. Bash, Python).
  • Accurately create and maintain documentation detailing the implemented network components, as well as relevant procedures and other documentation.
    Responsibility for our IT security related platforms. Key areas include Palo Alto firewalls, Juniper MAG SSL gateways, VPNs, Security policies, etc.
  • Work flexible hours. We are proud of the uptime of the trading environment, so every now and then you will be working outside of regular business hours to apply critical changes. This could be from your desk, your couch at home or also inside of one of our datacenters abroad.
    Liaise with external vendors, exchanges and providers to explore new technology solutions, implement new services or troubleshoot problems.

 

WHAT MAKES IT FUN?

 
  • One of the most fun aspects of the job is that we have a very quick feedback loop. We release early and often to get incremental benefits as they are implemented.
  • We operate at the bleeding edge of technology. If something new can potentially bring an advantage we will actively invest in developing and utilizing the solution as quick as we can.
  • We really believe in sharing knowledge and technology between the different offices. Much of our technology stack is shared between all three regions, and we provide opportunities to travel between the regions both for personal growth and to assist where people can have the biggest impact.
  • Our Client provides an opportunity to learn about financial markets and how exchanges work. We know from experience that a lot of people really enjoy learning about a field beyond their immediate area of expertise, it’ s one of the things that makes this job more interesting than others.
  • We employ a broad range of people with varying backgrounds. What they have in common is their superior technical expertise, their extraordinary smarts and their collaborative approach. We will not accept less.
