We are a small, high-performing proprietary trading firm building cutting-edge trading systems across global markets. We’re seeking a hands-on CTO who has personally built and operated low-latency trading systems and understands the full lifecycle of systematic trading — from exchange connectivity to strategy deployment and real-time risk management.
This is a build-and-lead role for someone who thrives in a high-performance environment and wants meaningful ownership over the firm’s technology and trading infrastructure.
What You’ll Do
- Architect, build, and optimize ultra-low latency trading systems in production.
- Design and maintain exchange connectivity, including onboarding new venues and market data feeds.
- Partner closely with traders and researchers to translate strategies into scalable, production-ready systems.
- Own system reliability, performance, and security across all trading platforms.
- Lead and mentor a small, elite engineering team, setting technical standards and development practices.
- Drive infrastructure strategy, including hardware, colocation, networking, and cloud where appropriate.
- Continuously improve latency, throughput, and fault tolerance across the trading stack.
What We’re Looking For
- Proven experience in proprietary trading or high-frequency trading (HFT) environments.
- Deep expertise in C++ and Python in production trading systems.
- Hands-on experience building trading engines, OMS, EMS, and market data systems.
- Direct experience onboarding trading systems to exchanges (FIX, binary protocols, custom APIs).
- Strong understanding of:
- Market microstructure
- Low-latency networking
- Real-time systems
- Risk management
- Strategy deployment pipelines
- Experience scaling systems from prototype to live trading.
- A builder mindset — you write code, design systems, and lead from the front.
Why This Role
- True technical ownership — shape the entire trading platform.
- Direct impact on P&L — your systems power live trading strategies.
- Lean, elite team — no bureaucracy, just performance.
- Upside participation — competitive comp + bonus + equity.
