About the role

Core Responsibilities

  • Work daily within a tight-knit unit of Traders and Quants to translate high-frequency strategies into production-ready code.
  • Build and tune trading applications using Modern C++, with a heavy focus on OS-level performance (e.g., CPU affinity, memory management, and kernel bypass).
  • Leverage Python to build high-speed data pipelines, backtesting frameworks, and real-time monitoring tools to analyze strategy behavior.
  • Act as the "systems expert" for the desk—diagnosing jitter, race conditions, or latency spikes by digging into the Linux stack (schedulers, interrupts, and syscalls).
  • Maintain a "zero-error" mindset, ensuring the absolute correctness of trading logic in a high-stakes, real-time environment.

Requirements

  • BS/MS in Computer Science or Computer Engineering with a strong academic focus on Operating Systems.
  • Professional-level understanding of C++ (pointers, memory layout, and concurrency).
  • Ability to write clean, efficient Python code for data analysis and automation.
  • Deep knowledge of Linux/Unix internals, including how the OS manages hardware resources and optimizing that interaction for speed.
  • A natural drive to deconstruct complex systems; enjoys reading man pages and figuring out the "why" behind system behavior.
