Job Description

Sector: Proprietary Trading


Compensation: Exceptional total package (above market base + heavy buy-side bonuses + excellent benefits)


My client, a globally recognized leader in the proprietary trading space, is seeking an exceptional Linux Systems Engineer to join their core infrastructure team. This is not a typical sysadmin role; it is a hybrid position for those who live and breathe systems-level programming, automation, and performance engineering.


You will be responsible for the heart of the firm's technological stack--the low-latency, high-performance Linux environment that drives their real-time trading systems. This group is the first and last line of defense for production stability, requiring a unique blend of deep theoretical knowledge and pragmatic, rapid-fire problem-solving skills.


A Glimpse into the Projects You'll Tackle:


While the core mandate is ensuring unparalleled platform stability and performance, your work will be varied and deeply technical. You can expect to be involved in projects such as:


Ultra-Low-Latency Kernel Tuning: Investigating and patching kernel and network stack behavior to shave off critical microseconds, using the most advanced profiling tools available.

Large-Scale Automated Provisioning: Designing the next generation of bare-metal automation to manage a globally distributed fleet of trading servers with absolute consistency and zero touch.

Deep Systems Performance Analysis: Developing custom tooling to perform real-time, fleet-wide analysis of hardware and OS performance, identifying anomalies before they impact trading.

Resilience and Chaos Engineering: Building systems to proactively test failure modes and ensure the trading platform can withstand any hardware or network fault.

Close Collaboration with Trading Strats: Working directly with quantitative researchers and developers to understand their system needs and co-design optimal hardware and OS configurations.

Who You Are:


You are a systems programmer at heart. You see the operating system not as a static platform, but as a complex, malleable piece of software to be understood, optimized, and mastered. You automate not because you're told to, but because you cannot tolerate manual, repetitive work.


Required Qualifications:


A profound, foundational understanding of operating system internals, with specific expertise in the Linux kernel.

Expert-level proficiency with the Linux command line and shell scripting (Bash).

Strong systems programming skills in C or C++ or Python or Go, with knowledge of concepts like virtual memory, process scheduling, and socket programming.

Practical experience with systems debugging and performance profiling tools Fundamental knowledge of networking (not at a network engineer's level) Experience in a high-performance computing (HPC) environment, low-latency trading, or a tech firm where systems performance is paramount.

* Background in configuration management at scale (e.g., Ansible, Puppet, Salt, or custom-built solutions)
