> Junior systems-focused Software Engineer working directly with traders and quants at a high-frequency trading firm. Optimize low-level trading applications in Modern C++ and Linux internals, build Python tooling for backtesting and monitoring, and diagnose latency issues in real-time trading systems.

## Job Description

## 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.
