Job description

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

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.

The Role

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.

What You’ll Do

• Build production‑grade Python automation and internal tools (not one‑off scripts) used daily by engineers and traders.
• Own Linux infrastructure end‑to‑end: BIOS/firmware, kernel tuning, CPU isolation, time sync (PTP), and repeatable deployments.
• Design and support networking basics that underpin trading: routing, VLANs, multicast/unicast, and how market data and orders flow.
• Work with RF fundamentals: wireless signals, antennas, interference, and link performance for critical comms paths.
• Manage remote devices and infrastructure with a strong operational mindset: change control, incident response, and vendor/contractor coordination across time zones.
• Travel to towers, data centres and remote sites (domestic and international) and participate in a global on‑call rotation, including occasional off‑hours work.

You Bring

• Solid Python for automation/tooling: you build CLIs, services, or libraries that teams adopt and maintain.
• Strong Linux systems skills in production environments.
• Networking fundamentals: routing, VLANs, TCP/UDP, multicast, and practical understanding of how data moves.
• RF basics: wireless propagation, antennas, interference, and real‑world link troubleshooting.
• Operational discipline: comfort with change control in high‑stakes environments; experience coordinating vendors, contractors, or field crews globally.
• Willingness to travel to sites and cover an on‑call rotation across time zones.

Nice-to-Have Bonuses

• Monitoring/observability: Grafana, Splunk, or similar for latency, jitter and tail‑latency dashboards.
• Regulatory/licensing exposure: FCC, FAA, permitting or similar compliance contexts.
• Hands‑on with RF test equipment or optical transport (dark/lit fibre, DWDM, etc.).
