Senior C++ Software Engineer - Strategy Development (Philadelphia)

A top global trading firm is hiring a Senior C++ Software Engineer to join a high‑impact Strategy Development team responsible for building and optimizing the core infrastructure that powers real‑time trading across global markets. This is a deeply technical, performance‑critical role where engineering quality directly influences trading and pricing outcomes. You'll operate close to the business, partnering with traders, quants, and senior engineers to build systems where precision, latency, and reliability are non‑negotiable.

This role may be based in either New York City or Philadelphia, PA. Why This Role Your software runs in production, at scale, directly affecting real‑time pricing and trading decisions You'll work alongside traders and quantitative researchers, not downstream from them Short development cycles with a strong bias toward engineering ownership and technical rigor Problems that demand mastery of modern C++, concurrency, and system‑level performance What You'll Work On Core C++ infrastructure supporting real‑time trading, pricing, and strategy execution Latency‑sensitive, event‑driven systems and execution pipelines Performance‑aware model and strategy integration Systems that require deep understanding of multithreading, memory behavior, and Linux internals Who We're Looking For We welcome engineers from elite, performance‑driven environments where correctness and real‑time constraints matter.This includes candidates with backgrounds in: High‑performance trading or electronic markets Game engines / AAA gaming Autonomous driving, robotics, or simulation platforms Scientific computing, real‑time graphics, or low‑level systems If you've built game engines, autonomy stacks, physics or simulation frameworks, or other high‑throughput real‑time systems, your skills will translate seamlessly. Responsibilities Architect and implement high‑performance C++ systems for live trading environments Optimize applications for latency, throughput, and fault tolerance Collaborate with traders and quants to translate trading needs into robust technical solutions Debug and resolve complex issues in real‑time production systems Contribute to system design, performance reviews, and technology evaluations Qualifications 5+ years of professional software engineering experience Deep expertise in modern C++ (C++17 / C++20 preferred) Strong foundation in systems programming, multithreading, and Linux Experience working on latency‑sensitive or real‑time systems Hands‑on experience with profiling, debugging, and performance optimization Degree in Computer Science, Engineering, Mathematics, or equivalent experience Strong communication skills and a collaborative, engineering‑first mindset
