Network Engineer

TheOpportunity

You'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. This position must be geographically located within +/- 3 hours EST.

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.

About Nascent

Founded in 2020, Nascent exists to build, expand, and capture opportunity, in open markets and permissionless technologies. Building from a base of permanent capital, we deploy assets across a range of both liquid and long-term strategies that ensure we are among the most active users of the open financial system we are helping to build. We’ve backed 100+ early-stage teams that we believe can change markets and expand what’s possible. At Nascent, we combine that venture + market pedigree with product-grade engineering to turn research into revenue: experiments that ship fast, are evaluated rigorously, and move P&L. We focus on models, low-latency infrastructure, and resilient systems that compound performance over time.

Our Team & Culture

We’re an interdisciplinary team of engineers, quants, and operators who treat skill-building like a sport. The culture is competition + curiosity: push to win, share learnings, and iterate publicly through red-teams, internal games, and post-mortems. Autonomy isn’t a perk — it’s how we ship.
