What you'll do

• Design, build, and optimize latency-critical C++ components for the core trading platform.
• Develop electronic market-making systems including real-time pricing, hedging, and pre-trade risk controls.
• Build instrumentation and benchmarks to measure and reduce tail latency and jitter.
• Optimize software/hardware interactions including CPU caches, NUMA, and kernel-bypass networking.
• Develop, review, and debug high-quality production code while setting engineering standards.
• Diagnose production issues during live trading and automate remediation of recurring problems.
• Implement high-performance market data feed handlers and order books for various asset classes.

What we're looking for

• Formal training or certification in software engineering concepts and 10+ years of applied experience.
• 5+ years of experience leading technologists to manage and solve complex technical items.
• Expert-level modern C++ (C++17/20) including templates, memory management, and compiler-generated code.
• Hands-on experience designing and operating latency-sensitive production systems with measurable performance improvements.
• Deep understanding of software/hardware interaction including CPU caches, NUMA, branch prediction, and kernel-bypass networking.
• Strong multithreading skills including the C++ memory model, atomics, and lock-free data structures.
• Proficiency in Linux systems programming, networking (TCP, UDP multicast), and performance tools like perf, gdb, eBPF, or VTune.
• Experience in electronic trading, market microstructure, or developing high-performance market data feed handlers (preferred).
