TheOpportunityYou'll own the network infrastructure that connects Nascent's trading systems to exchanges, colocations, and internal platforms - the physical and logical fabric that every microsecond of execution depends on. This is a hands-on build-and-operate role: you'll design low-latency network topologies, manage colocation cross-connects and exchange connectivity, maintain precision time synchronization, and keep firewall and routing policy tight. You'll work alongside systems engineers, SREs, and quant infrastructure teams who treat deterministic performance as a first-class engineering discipline.
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.
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.
About you- 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.
