Position Overview & Specifications

About the Position

Jane Street’s numerous distributed systems are built on an agile, reliable, multi-vendor network infrastructure that supports all traffic profiles from trading to internet connectivity.

We are looking for a Junior Network Engineer who will help us maintain the team’s highest level of service and scale our network ahead of our business’ demands, while pushing for more standardisation through automation.

Strong communication and interpersonal skills will be needed as you collaborate with colleagues across the firm globally. You will find and resolve issues, plan and execute deployments, and improve systems where possible. Getting the details right and keeping good records are critical in this role. Striving to improve the team through documentation and contributing to our monitoring and automation systems is a must.

A typical day in the Network Engineering team includes:

  • Working on cross-team projects such as site expansions and new colocation builds, with the help of our project managers
  • Interacting with stakeholders to provision new market data feeds and connections to third parties
  • Contributing to support tasks and actively taking steps to improve the team's ability to monitor the network effectively, through scripting and/or conveying requirements to our dedicated developers

About You

  • Experience working across LAN and WAN networks
  • Experience with routing and network protocols (OSPF, BGP, PIM-SM)
  • Experience troubleshooting transport protocols (TCP/UDP)
  • Experience working with Linux and proficient in a programming language
  • Ideally experience with overlay networks (EVPN, VxLAN)
  • Eagerness to automate your workflow to increase efficiency
  • High capacity to learn; we are more interested in how you think than what you already know
  • High capacity for context switching and organising your workload
  • Clear communication skills with the ability to maintain a high degree of customer service
  • A flexible and reliable team player who enjoys working in a collaborative environment
  • Fluency in English is required
