Wireless Network Engineer

Job Description

Wireless Engineer – Global Trading Firm (Low-Latency, RF & Operations)

\n

\n

A global, market-leading trading firm is hiring an Infrastructure Engineer to own the reliability, automation and performance of its latency-critical trading and communications stack – from Linux servers and networks to wireless/RF links and remote sites.

\n

\n

The Role

\n

You’ll be the operational backbone for systems where microseconds matter and mistakes are costly: building robust Python tooling others rely on, hardening Linux environments, and ensuring data moves reliably across networks and wireless links – including towers, data centres and remote sites worldwide.

\n

\n

What You’ll Do

\n

\n
• Build production-grade Python automation and internal tools (not one-off scripts) used daily by engineers and traders.

\n

• Own Linux infrastructure end-to-end: BIOS/firmware, kernel tuning, CPU isolation, time sync (PTP), and repeatable deployments.

\n

• Design and support networking basics that underpin trading: routing, VLANs, multicast/unicast, and how market data and orders flow.

\n

• Work with RF fundamentals: wireless signals, antennas, interference, and link performance for critical comms paths.

\n

• Manage remote devices and infrastructure with a strong operational mindset: change control, incident response, and vendor/contractor coordination across time zones.

\n

• Travel to towers, data centres and remote sites (domestic and international) and participate in a global on-call rotation, including occasional off-hours work.

\n

\n

\n

You Bring

\n

\n
• Solid Python for automation/tooling: you build CLIs, services, or libraries that teams adopt and maintain.

\n

• Strong Linux systems skills in production environments.

\n

• Networking fundamentals: routing, VLANs, TCP/UDP, multicast, and practical understanding of how data moves.

\n

• RF basics: wireless propagation, antennas, interference, and real-world link troubleshooting.

\n

• Operational discipline: comfort with change control in high-stakes environments; experience coordinating vendors, contractors, or field crews globally.

\n

• Willingness to travel to sites and cover an on-call rotation across time zones.

\n

\n

Nice-to-Have Bonuses

\n

\n
• Monitoring/observability: Grafana, Splunk, or similar for latency, jitter and tail-latency dashboards.

\n

• Regulatory/licensing exposure: FCC, FAA, permitting or similar compliance contexts.

\n

• Hands-on with RF test equipment or optical transport (dark/lit fibre, DWDM, etc.).
