Linux Engineer (low latency)

OverviewMy client, an investment manager specialising in systematic trading, is looking for a talented Linux Engineer to join their high-performance, low-latency platform team.

You’ll collaborate with some of the industry’s top developers, quants, and platform engineers, helping to design, deploy, and refine deterministic, microsecond-level systems.

If you thrive in the Linux ecosystem, enjoy solving kernel-level challenges, and want to push bare-metal systems to their limits while writing performance-critical code, this could be the role for you.

Responsibilities

Collaborate with developers, quants, and platform engineers to design, deploy, and refine high-performance low-latency systems.

Contribute to kernel-level work and performance-critical code in Linux environments.

Help ensure deterministic, microsecond-level system behavior on a high-performance platform.

Qualifications

Demonstrated capability working in low-latency domains where timing is paramount.

Practical exposure to data-path acceleration methods that avoid conventional kernel boundaries.

Skilled in interpreting hardware-level performance signals and applying profiling/analysis tools for deep system diagnostics.

Proficiency in at least one mainstream programming language.

Solid grasp of modern CPU microarchitectures and their performance implications.

Familiarity with precise time-synchronisation mechanisms (e.g., PTP) and the examination of packet traffic at scale.

Experience automating infrastructure through configuration/orchestration frameworks such as Ansible, Terraform, or Python is a plus.

Location and scheduleIn-office requirement: at least 4 days per week in London.
