## About the Role

* You've worked in latency-sensitive, colocation, or trading environments - you understand why microseconds matter and how network decisions land on execution.
 * You design infrastructure from scratch rather than only operating what someone else built.
 * You script your way out of repetitive work; automation is instinct, not an afterthought.
 * You own incidents end to end - you don't escalate and wait, you dig in until it's resolved.
 * You're comfortable as one of two network engineers: small team, real ownership, nowhere to hide.
 * You treat on-call as part of the craft, not an imposition.
 * You translate network decisions into language systems engineers, SREs, and quant teams can act on.

Preferred experience

 * 3+ years hands-on with L2/L3 networking in latency-sensitive, colocation, or trading environments.
 * Strong working knowledge of BGP and OSPF - configuration, troubleshooting, and design in production.
 * Production experience with PTP (IEEE 1588) or comparable precision time synchronization.
 * Proficiency in Python for network automation, configuration management, or operational tooling.
 * Hands-on firewall configuration and management (Cisco ASA, Palo Alto, or equivalent).
 * Packet capture and protocol-level troubleshooting (tcpdump, Wireshark).
 * Nice to have: CCNP/CCIE with practical work behind it; IaC for network config (Ansible, Terraform); hybrid-cloud connectivity (AWS Direct Connect, Azure ExpressRoute); DPDK or kernel-bypass exposure.

## Description

This isn't a ticket-queue seat inside a large NOC. You'll be one of two network engineers with direct ownership over architecture decisions, vendor relationships, and the tooling you build to monitor and automate the stack - designing connectivity from scratch, not just maintaining what someone else built. The problems are real: packet captures at the switch port, PTP drift investigations, firewall policy reviews that directly affect trade flow - and you'll have the autonomy to solve them end to end. This position must be geographically located within +/- 3 hours EST., * Own colocation connectivity: cross-connects, exchange feeds, and carrier relationships across production colo facilities.

 * Design and maintain low-latency L2/L3 network topologies for trading infrastructure.
 * Configure, troubleshoot, and optimize BGP and OSPF routing in production.
 * Maintain precision time synchronization (PTP / IEEE 1588) across trading and infrastructure systems.
 * Manage firewall policy (Cisco ASA, Palo Alto, or equivalent) - changes that directly affect production traffic paths.
 * Write Python tooling for network automation, configuration management, and operational monitoring.
 * Perform packet capture and protocol-level troubleshooting (tcpdump, Wireshark).
 * Build and maintain runbooks, network diagrams, and infrastructure documentation.
 * Participate in the on-call rotation and own incidents end to end, from triage through post-mortem.
