Principal C++ Engineer

Principal C++ Software Engineer – Trading Execution - NYC/Chicago - Hybrid

A leading proprietary trading firm is hiring C++ engineers to build and improve the execution systems behind its options market-making business.

The engineering goal is to make trading faster, more efficient and more reliable, reducing latency, improving execution decisions and ensuring systems perform under demanding market conditions.

You’ll work on performance-critical C++ systems, partnering directly with traders, quants and other engineers. There’s a clear connection between the code you write, how effectively the firm trades and the commercial impact of your work.

What You’ll Do

• Build and improve C++ execution engines and automated trading systems
• Identify bottlenecks and reduce latency across the execution path
• Develop and refine execution logic alongside traders and quants
• Improve system reliability, scalability and operational simplicity
• Investigate production behaviour and turn performance insights into engineering improvements
• Own changes from design and implementation through to live trading

What We’re Looking For

• Strong C++ skills and experience building production software
• Strong CS fundamentals, including algorithms, data structures and concurrency
• Experience with systems where performance, reliability and correctness matter
• Engineers who enjoy ownership, technical collaboration and measurable impact
• No prior trading or quantitative finance experience required.

We welcome engineers from technology companies and other performance-focused environments.

All conversations strictly confidential.
