About the role
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.
What you'll bring
- 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.
- Packet capture and protocol-level troubleshooting (tcpdump, Wireshark).
- 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.
