Latency Critical & Low-Level C++ Software Engineer

Latency Critical & Low Level C++ Software Engineer

Chicago – Onsite

About The Role:

We’re hiring onsite in Chicago for two C++ engineering roles:

• Latency-Critical C++ Engineer: Build high-performance systems used directly by traders and quants, tackling challenging problems with real-time impact in live markets.
• Low-Level C++ Engineer: Optimize ultra-low latency trading systems across the full stack, working at the hardware–software boundary to maximize performance.

.

What You’ll Do:

As the Latency-Critical C++ Engineer, you will:

• Write and optimize ultra-low latency C++ across trading systems that is performance-critical C++ across our low-latency systems, from order execution to market connectivity

• Profile, benchmark, and eliminate bottlenecks end-to-end
• Partner with traders/quants to turn performance needs into efficient code
• Own systems from development through production
• Apply modern C++ to solve real-time performance challenges

As the Low-Level C++ Engineer, you will:

• Develop high-performance, ultra-low latency C++ systems to improve performance-critical C++ applications, ensuring ultra-low latency and high throughput
• Work closely with hardware, FPGA, and systems teams
• Diagnose and fix real-time performance and stability issues
• Create tools for deep system profiling and monitoring

What We’re Looking For:

For the Latency-Critical C++ Engineer, we are looking for:

• BS in CS/CE or equivalent
• 2+ years C++ focused on performance and correctness
• Strong modern C++ (C++17/20), concurrency, memory, STL
• Solid algorithms, data structures, and low-level systems knowledge
• Ownership mindset with attention to trade-offs and code quality
• Depth over breadth

For the Low-Level C++ Engineer, we are looking for:

• BS in CS/CE or equivalent
• 2+ years C++ in high-performance environments
• Strong algorithms, data structures, modern C++ (C++17/20)
• Experience with multithreading and performance tuning
• Ability to analyze results and optimize systems and diven to continuously improve
• Clear communication across technical and non-technical teams
• Driven to continuously improve
