Junior Software Engineer

About the role

Geneva Trading is seeking a Junior Software Engineer with a s ystems-programming pedigree to join our Chicago headquarters. In this role, you will be an integral part of a specialized development staff that works side-by-side with Traders and Quantitative Researchers. We aren't looking for a "back-office" developer; we need a problem solver who wants to sit at the intersection of code and the markets. You will use your understanding of Operating Systems and low-level architecture to ensure our strategies are the fastest and most reliable in the world. This role is for the curious mind -the engineer who doesn't just want to write a strategy but wants to understand exactly how the Linux kernel handles every packet that strategy sends. Core Responsibilities Collaborative Development: Work daily within a tight-knit unit of Traders and Quants to translate high-frequency strategies into production-ready code. Systems-Level Optimization: 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). Research & Diagnostic Tooling: Leverage Python to build high-speed data pipelines, backtesting frameworks, and real-time monitoring tools to analyze strategy behavior. Deep-Dive Problem Solving: 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). Execution Excellence: Maintain a "zero-error" mindset, ensuring the absolute correctness of trading logic in a high-stakes, real-time environment. The Technical Profile Education: BS/MS in Computer Science or Computer Engineering with a strong academic focus on Operating Systems . Language Proficiency: C++: Professional-level understanding of pointers, memory layout, and concurrency. Python: Ability to write clean, efficient code for data analysis and automation. OS Fundamentals: Deep knowledge of Linux/Unix internals . You should understand how the OS manages hardware resources and how to optimize that interaction for speed. The "Curious" Mindset: A natural drive to deconstruct complex systems. You are the person who reads the man pages and enjoys figuring out the "why" behind a system's behavior. The Geneva Environment High-Touch Collaboration: You are part of the trading desk's heartbeat, where feedback loops between code and market impact are measured in microseconds. Intellectual Rigor: Solve non-trivial puzzles alongside some of the brightest minds in the industry. Chicago Culture: Work in our state-of-the-art Chicago office, enjoying the energy of the trading floor combined with a flat, meritocratic structure.
