Description

Linux Engineer - Hong Kong - relocation support and visa sponsorship available

Join a leading global trading firm where Linux sits at the heart of production trading systems. You'll work on the critical infrastructure that powers low-latency, high-reliability workloads, partnering closely with Trading, Technology, and Operations.

What you'll do

• Own and improve the Linux platform that underpins production trading systems.
• Debug tricky systems issues end-to-end (including kernel performance) and resolve live production incidents with clear root-cause analyses and durable fixes.
• Build tooling for deployment automation, scalable configuration management, and comprehensive monitoring - automating wherever it reduces error rate and operational load.
• Develop and maintain management tools; dive into Unix/Linux internals when performance or reliability demands it.
• Collaborate across teams to roll out firm-wide changes safely and repeatably.

What you bring

• Experience in electronic trading, hedge funds, proprietary trading/market making, exchanges, or similarly time-critical, high-throughput, high-frequency/low-latency environments.
• Deep knowledge of operating system fundamentals, plus fluency with the Unix command line and shell scripting.
• Practical experience with modern Linux systems and systems programming concepts: C, sockets, virtual memory, and the process lifecycle.
• Strong troubleshooting skills and familiarity with profiling/debugging tools such as gdb, perf, DTrace, eBPF, or SystemTap.
• Solid understanding of network fundamentals and common protocols.
• Programming experience in any language (functional languages are a plus).
• Bachelor's degree in Computer Science/Software Engineering or equivalent experience.

Why this role

• High impact: your work directly supports real-time trading.
• Variety: anything from kernel-level investigations to automation and tooling.
• Culture: engineer-led, collaborative, and obsessive about correctness and reliability.
• Industry leading compensation
