Wireless Network Engineer (RF & Automation)

Wireless Network Engineer (RF & Automation) 📍 Chicago, IL (Chicago-based candidates only) 💰 Above-market compensation The role Our client is a high-frequency trading firm running a high-performance wireless network. Signals are beamed between towers, rooftops and data centres, linking two major financial exchanges, where every microsecond counts. Their field and operations team builds and maintains that network, and they now need an engineer to keep it visible and healthy. Youll catch issues before they become outages and automate the system so it gets smarter over time. Its a highly competitive space where the traditional approach doesnt always cut it, so they want someone who enjoys finding creative solutions. In return, they pay well above market rates. What youll do Monitoring and alerting: Build and improve tools in Splunk, Grafana and custom code to track signal quality, spot degradation trends and alert before small issues snowball. The aim is to catch problems while theyre still data points, not outages. End-to-end troubleshooting: When traffic isnt flowing right, trace the issue across wireless links, access points and user connections. That means reading signal data, running packet captures, checking device connectivity and following the trail wherever it leads. Hands on the network: Design new wireless paths, work with regulators on licensing and bring new links online. Youll also get more performance out of the existing infrastructure across both exchanges. Incident response: When something breaks, you lead the response. Find it, fix it, document it, then feed the lessons back into monitoring and design so it cant break the same way twice. Playbooks: Write the runbooks that let field crews and on-call engineers handle situations confidently without you on the phone. What youll bring Python for automation and tooling. You can build tools other people actually use, not just one-off scripts. Strong Linux skills Solid networking fundamentals: routing, VLANs and how data moves RF fundamentals: wireless signals, antennas and interference Experience managing remote devices or infrastructure Comfortable working under change control in environments where mistakes matter Able to coordinate vendors, contractors and field crews across time zones Nice to have Monitoring tools such as Grafana or Splunk Regulatory or licensing experience (FCC, FAA, permitting) RF test equipment or optical transport experience Please note Travel to towers, data centres and remote sites, both domestic and international On-call rotation across global time zones, including occasional out-of-hours work Hamilton Barnes
