Summary

We're looking for a C++ Lead to architect and build ultra-low-latency trading systems for crypto markets. This is a genuinely hands‑on leadership role; you'll be writing code as an individual contributor while also leading and mentoring a team of engineers around you. You'll own the core trading infrastructure decisions, drive how the architecture evolves, push for engineering quality across the team, and make sure delivery actually happens on a platform that needs to be scalable, fast, and reliable all at once.

What You'll Be Doing

• Architecting and building ultra-low-latency trading infrastructure from the ground up
• Leading development across OMS, execution engines, and market data platforms
• Driving performance optimization, scalability, and system reliability as ongoing priorities, not one-time fixes
• Designing exchange connectivity through REST, WebSocket, and FIX
• Mentoring engineers and shaping the technical architecture as the team and platform grow

What We're Looking For

• 10+ years working in Modern C++ (C++17/20), this is a senior bar, not a stretch goal
• Deep expertise in low-latency, multithreaded, distributed systems
• Substantial background in HFT, algorithmic trading, electronic trading, market making, or exchange connectivity; any combination of these is fine
• Strong Linux systems programming, networking, and PostgreSQL experience
• Crypto or capital markets experience is a strong plus, though not a hard requirement
