About the role
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.).
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
