Senior Network Engineer

Must-Have

8–10+ years of experience in network engineering, ideally in high-performance environments

3–5+ years of experience with low-latency connectivity, preferably in high-speed trading or financial services

Strong understanding of low-latency networking principles

Experience with server-to-switch connectivity using technologies (For i.e. Glue)

Exposure to financial trading environments is ideal, but broader low-latency experience is acceptable

Expertise in multicast, BGP, and low-latency switching hardware (e.g., Arista 7130, Cisco 350 series or similar)

Advanced troubleshooting skills, including:

Proficiency with Wireshark and packet capture analysis

Experience using tap aggregation tools for traffic inspection

Ability to capture and analyze data for both real-time troubleshooting and post-event research

Highly motivated and passionate, with a proactive approach to taking on new responsibilities and mastering emerging skill sets

Plusses

Experience with Layer 1 low-latency technologies

Familiarity with cloud networking, especially in hybrid or multi-cloud environments (AWS most relevant)

Background in global infrastructure projects or distributed systems (For ex. In Frankfurt, London, Asia, etc.)

Network automation skills, including scripting or use of tools like Ansible, Python, or Terraform

Certifications (Cisco, Arista, CorVel)

Day-to-Day

As Sr. network engineer, on a day-to-day basis, about 25% of the time is spent on troubleshooting, which can increase during critical incidents or when addressing architectural challenges. Another 25% is focused on strategic planning, while the remaining 50% is dedicated to building and executing solutions-- as a senior team member, the balance shifts more toward strategic oversight. Key initiatives include global infrastructure build-outs, such as projects in Frankfurt and London, and a major migration effort within New Jersey, moving from one data center space to another. Over the next year or two, additional migrations and expansions are expected, including the development of a new data center in Europe. The role also involves revamping global routing architecture and supporting low-latency initiatives globally, expanding into Asia more so as the year continues. Cloud integration, particularly with AWS, is an ongoing focus as part of the broader modernization strategy.
