Troubleshoot system issues in live trading environments with precision and speed.
Collaborate with network and hardware engineers on server architecture, co‑lo deployments, and performance testing.
Required Skills
Strong expertise in Linux internals (networking stack, memory, scheduling, interrupts).
Proven low‑latency or high‑performance systems experience.
Skilled with performance tools (perf, eBPF, tcpdump, etc.) and scripting (Bash/Python).
Strong hardware awareness (NUMA, CPU pinning, NIC technologies).
Preferred Experience
Familiarity with kernel bypass tech (Solarflare/OpenOnload, VMA, DPDK).
Understanding of market data feeds or FPGA‑accelerated environments.
Attributes
Detail‑oriented, calm under pressure, and highly analytical.
Clear communicator and proactive problem solver.
Seniority level Mid‑Senior level
Employment type Full‑time
