The reason you might care: If you like networks that actually matter, this will land with you. You will be working on live, latencyâsensitive platforms where uptime, routing decisions, and clean change execution have realâworld consequences. This isnât internal IT. Itâs production infrastructure used by external clients who expect things to work â every day, without excuses.
You will get:
- Ownership of real exchangeâstyle network infrastructure.
- Exposure to client onboarding, upgrades, and complex change windows.
- A mix of project work and handsâon operational responsibility.
- Enough scale to be interesting, without the politics of a megaâbank.
- A team that plans properly, documents properly, and trusts engineers to think.
What you will actually be doing: You will sit at the heart of the network operation. That means:
- Supporting live platforms during trading hours.
- Working directly with clients during onboarding and technical upgrades.
- Designing, building, and upgrading network infrastructure endâtoâend.
- Racking, configuring, testing, documenting â the full lifecycle.
- Making controlled changes to routing, switching, firewalls, and VPNs.
- Taking part in a sensible support rota (with planned outâofâhours work for major changes).
- Dealing with vendors when escalation is needed â not being blocked by them.
You will report into a handsâon infrastructure leader who understands networks, not a spreadsheet.
What you will need to bring: This will suit you if you already know your way around production networks and want more responsibility, not just tickets. You will need:
- Several years in network engineering or network support roles.
- Strong routing and switching fundamentals (BGP, OSPF, ACLs).
- Handsâon experience with Cisco and/or Arista environments.
- Confidence working with firewalls and VPNs (Fortinet or similar).
- Experience supporting or building VXLAN EVPN architectures.
- Comfort troubleshooting with packet captures and real diagnostics.
Useful extras (not dealâbreakers):
- Exposure to multicast (PIM, IGMP, MSDP).
- Lowâlatency or tradingâstyle networks.
- VMware, cloud platforms, or Linux admin.
Most importantly: you stay calm when things matter, document what you touch, and think before you change.
