The reason you might care

If you like networks that actually matter, this will land with you.

You’ll be working on live, latency-sensitive platforms where uptime, routing decisions, and clean change execution have real-world consequences. This isn’t internal IT. It’s production infrastructure used by external clients who expect things to work — every day, without excuses.

You’ll get:

• Ownership of real exchange-style network infrastructure

• Exposure to client onboarding, upgrades, and complex change windows

• A mix of project work and hands-on operational responsibility

• Enough scale to be interesting, without the politics of a mega-bank

• A team that plans properly, documents properly, and trusts engineers to think

And yes — this is a grown-up environment. People collaborate, challenge ideas, and get on with the work.

What you’ll actually be doing

You’ll 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 end-to-end

• Racking, configuring, testing, documenting — the full lifecycle

• Making controlled changes to routing, switching, firewalls, and VPNs

• Taking part in a sensible support rota (with planned out-of-hours work for major changes)

• Dealing with vendors when escalation is needed — not being blocked by them

You’ll report into a hands-on infrastructure leader who understands networks, not a spreadsheet.

What you’ll need to bring

This will suit you if you already know your way around production networks and want more responsibility, not just tickets.

You’ll need:

• Several years in network engineering or network support roles

• Strong routing and switching fundamentals (BGP, OSPF, ACLs)

• Hands-on 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 deal-breakers):

• Exposure to multicast (PIM, IGMP, MSDP)

• Low-latency or trading-style networks

• VMware, cloud platforms, or Linux admin

Most importantly: you stay calm when things matter, document what you touch, and think before you change.
