The Role

Most backtests look brilliant until they meet a live order book. Your job is making sure this one survives the trip.

You'll join the systematic trading arm of a privately owned investment group as it takes a futures strategy out of research and UAT and into live markets, trading the owners' own capital. You'll own the critical path end to end: market data, execution, broker connectivity and the hard limits that sit between a bug and a margin call.

You'll work alongside trading, quant and engineering colleagues, pick up the phone to the broker when a FIX session misbehaves, and have real say over architecture and engineering standards. As the trading capability grows, you'll have a clear path to Staff Engineer.

Day-to-day, you work remotely, and you'll meet the team in person at regular company days.

What makes you a great fit

• You write expert-level C++ and have five or more years shipping it into production systems.
• You understand exchange-traded futures properly: contract specs, tick values, leverage, margin, rolls and mark-to-market P&L.
• You've built or run systematic trading systems with automated risk limits, kill switches and reconciliation against broker fills and positions.
• Hands-on FIX experience, ideally against Interactive Brokers, CME or similar institutional infrastructure, puts you at the front of the queue.

The broader technical team uses: C++, Python, NumPy, SciPy, pandas, SQL, FIX, Docker, CI/CD, Infrastructure as Code, Kubernetes.
