Job summary

Nascent is seeking a hands-on Network Engineer to own the architecture and operation of the firm’s trading infrastructure. You will design low-latency L2/L3 topologies, manage colocation connectivity, and enforce precise time sync across systems while building Python tooling to automate this stack.

You will work with SREs and quant teams, own incidents end to end, and contribute to vendor relationships. You’ll be one of two engineers with clear ownership, shaping network decisions and policies

Qualifications

• 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.

Responsibilities

• 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.
