About the Position
We are looking for an experienced Network Engineer to join our Network Security team to help us to run, scale and continuously improve our network security infrastructure through hands-on operations, design, and implementation. The ideal candidate would have strong networking fundamentals and experience with security appliances such as firewalls and proxy to join our Network Security team.
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. Supporting such a large multi-function network requires advanced tooling for monitoring and automation.
Strong communication and interpersonal skills will be needed to collaborate with colleagues across the firm globally. You will find and resolve issues, plan and execute deployments, and improve systems where possible. In this role, we’ll look to leverage your advanced networking skills and security knowledge to:
Work closely with Network Engineering on design and deployment of security perimeter and adjacent network infrastructure
Effectively manage and continuously evolve network segmentation, DMZ, and other aspects of network security
Evaluate and lab test new platforms for our network security infrastructure
Collaborate with Cybersecurity on detection and mitigation of threats and vulnerabilities on our network
Interface with application owners and traders to enable business workflows in a secure way
Proactively enhance support by improving network infrastructure observability, scripting, and communicating requirements to our software engineers
Improve our network security processes and documentation
A holistic approach to system design is critical for this role. The Networking department prioritizes flexibility, compatibility, and efficiency when crafting solutions, all while seeking ongoing buy-in and feedback from users across the firm. Our firm’s culture prizes intellectual humility, openness, and continuous improvement, which translates directly to the daily work of this team. We’re all partners working towards shared goals and are always looking for the next best idea that will make our work stronger.
Your strong communication skills and analytical thinking will be invaluable as we support the daily work of our colleagues and keep our systems operating at the highest standard.
About You
7+ years of experience operating and deploying network infrastructure
Experience with routing and network protocols (OSPF, BGP, PIM-SM)
Experience troubleshooting transport protocols (TCP/UDP)
Strong understanding of firewall hardware architecture, performance metrics, and its functional components
Experience with firewall configuration and troubleshooting
Understanding of Public Key Infrastructure and related technologies
Understanding of modern encryption techniques
High capacity to learn; we are interested in how you think, not just what you know
Ability to context switch, while still being able to prioritize and organize your stack
Ideally experience with overlay networks (EVPN, VxLAN)
A flexible and reliable team player who enjoys working in a collaborative environment
Proficiency in a programming language is preferred
Fluency in English is required
