Bare-Metal Nanosecond-Latency Infrastructure Engineer

DUDOK; Amsterdam; Hybrid; EUR 120,000 - 150,000; Full time

Job summary

Barak Capital Market Making in Amsterdam seeks an Infrastructure Engineer who thrives on squeezing every microsecond out of a system. You will own the performance, reliability, and automation of our bare-metal trading infrastructure from BIOS to application level.

You will implement precision time synchronization (PTP/PPS), kernel-bypass networking, and observability tooling to profile latency and tail-latency.

Qualifications

• 4+ years in a Linux infrastructure, SRE, or performance engineering role.
• Deep Linux knowledge: kernel tuning, scheduling, memory management and I/O.
• Hands-on with kernel-bypass networking tools and frameworks.
• Experience with time synchronization at scale (PTP/PPS).
• Scripting and automation in Bash/Python; configuration management tools.
• CI/CD tooling experience in bare-metal or on-prem contexts.
• Comfort with hardware settings and colocation environments.
• Familiarity with perf, ftrace, flamegraphs, eBPF/bpftrace, cyclictest.

Responsibilities

• Own and optimize bare-metal Linux infrastructure end-to-end from BIOS to app-level performance.
• Implement and maintain precision time synchronization across the trading environment.
• Configure and tune kernel-bypass networking for ultra-low-latency paths.
• Profile latency at all layers and optimize interrupts, NUMA, and memory usage.
• Build and maintain CI/CD pipelines and IaC for repeatable deployments.
• Develop monitoring focused on latency distribution, jitter, and tail latency.
• Collaborate with quantitative developers and trading teams to co-design infrastructure.
• Manage network infrastructure including switch configuration and colocation connectivity.
