Mid-level experience and metro location increase competition, but niche low-latency skillset reduces applicant pool.
Role requires specialized low-latency trading network skills and exchange connectivity, limiting cross-industry transferability.
Multiple mandatory low-latency networking protocols, hardware, and a 3+ years requirement create strict filters.
Design, deploy, and troubleshoot low-latency network infrastructure supporting quantitative trading operations.
Manage connectivity to global stock exchanges, brokers, market-data providers, and ISPs, ensuring high availability and redundancy.
Automate operational tasks, maintain documentation, and coordinate network changes across multiple third-party stakeholders including data centers and telecom providers.

Experience configuring and supporting Cisco Nexus, Arista, or similar network devices.
Familiarity with low-latency technologies such as cut-through switching, hardware timestamping, FPGA devices, and kernel-bypass networking.
Knowledge of datacenter installation standards including cabling (DAC/AOC), optics (SFP/SFP+/QSFP), and PTP clock synchronization.
Experienced with designing and maintaining ultra-low latency networks for high-frequency or algorithmic trading environments.
Skilled in collaborating with multiple vendors and third-party data center teams for network deployment and maintenance.
Proficient in automating network operations and incident root-cause analysis using scripting tools like Python, Bash, or Ansible.
