Wireless Network Engineer

Wireless Network Engineer

A leading quantitative trading firm is hiring a Wireless Network Engineer to build, automate, and operate the ultra-fast network that connects financial markets. The role combines software development, RF engineering, and production network operations. You’ll help find faster routes while keeping existing links reliable.

What you’ll do

• Design and assess wireless paths, including line of sight, signal strength, interference, antenna placement, and frequency planning.
• Commission and optimise links using licensed microwave, millimetre wave, free-space optics, and other wireless technologies.
• Build Python tools to monitor link performance, automate device control, and speed up fault diagnosis.
• Integrate radios, amplifiers, controllers, and power systems using SNMP, serial/TCP connections, and vendor APIs.
• Investigate live incidents, coordinate field repairs, and turn findings into better monitoring and network design.
• Work on the supporting infrastructure, including fibre connections, DWDM, exchange cross-connects, and precision timing.
• Coordinate new sites, vendors, and field crews, and plan changes to live networks.

What you’ll bring

• Strong practical Python , Linux , and Git experience, alongside networking fundamentals such as routing, multicast, Ethernet, and VLANs.
• You’ll also need hands-on RF knowledge: link budgets, spectrum analysis, interference, and antenna systems.
• Experience with tools such as Grafana, Icinga, Splunk, ClickHouse, Docker, or Kubernetes would be useful, as would familiarity with telecom licensing and site development.
• The role involves travel to towers, rooftops, and data centres, plus participation in an international on-call rotation. It would suit someone who enjoys building tools as much as solving complex problems on a live network.
