Job description

A leading proprietary trading firm in NYC is expanding its core engineering team. We're looking to find a highly skilled C++ Developer to help build, optimize, and scale the low-latency systems that power our trading strategies. You’ll work shoulder-to-shoulder with quantitative researchers, platform engineers, and traders to push the boundaries of performance, reliability, and execution speed.

What You’ll Work On

• Develop and optimize ultra-low-latency C++ systems used for real-time market data processing and execution.
• Build high-performance exchange connectivity, order routing, and distributed compute components.
• Profile, tune, and refactor performance-critical code for microsecond-level improvements.
• Work closely with quants to translate research models into robust, production-ready systems.
• Contribute to architectural decisions around networking, concurrency, memory management, and fault tolerance.
• Enhance internal libraries, frameworks, and dev tooling to support a rapidly evolving trading environment.

What You Bring

• C++ (C++17/20) with deep understanding of performance, threading, and systems-level programming.
• Strong grasp of algorithms, data structures, CPU architecture, cache behavior, and network I/O.
• Experience with low-latency, high-throughput, or real-time systems (finance, gaming, telecom, HPC, etc.).
• Comfort working in Linux environments and using performance tools (perf, VTune, Valgrind, flame graphs, etc.).
• Ability to write production-quality code with an emphasis on reliability, testing, and maintainability.
• Bonus: experience with market data feeds, exchange protocols, FIX, or any trading-adjacent systems.

Why This Firm

• Work on mission-critical, latency-sensitive systems where engineering directly impacts PnL.
• Highly collaborative environment—engineers, quants, and traders work as one team.
• Flat structure, fast decision-making, and access to cutting-edge hardware/software.
• Competitive compensation with significant upside tied to engineering impact.
• Opportunity to solve challenging problems at scale in one of the world’s most performance-driven industries.

Our client is looking to pay a base package of $300-350k + bonus bringing comp package up to $1M in first year total guaranteed.
