Job description

C++ Developer – Smart Order Routing

Ready to build the fastest paths to market? If you're a performance-obsessed C++ engineer with deep experience in low latency trading systems and smart order routing, this is the challenge you've been looking for.

This is an opportunity to work at the sharp end of trading technology – designing, building, and refining ultra-low latency software used in live front-office environments. You’ll work across the full software stack and collaborate with high-performing market data teams to create systems that compete at nanosecond scale.

Whether you're architecting new systems from scratch or tuning every last cycle out of a performance-critical loop, you’ll be trusted to make technical decisions, take ownership, and mentor others. It’s greenfield meets precision engineering – and your input won’t just be welcome, it’ll be expected.

What’s on Offer

• Significant ownership in designing and building latency-critical components from day one.

• Autonomy to drive greenfield projects from architecture to release.

• A high-trust environment where your technical leadership and mentoring are valued.

• Chance to work with some of the most modern tools in high-performance C++ development.

What You’ll Need

• Minimum 5 years’ experience building low latency trading systems in C++11 or above.

• Hands-on experience with Smart Order Routing and Market Data – this is essential.

• A track record of writing performance-sensitive, multithreaded applications.

• Proven experience with code profiling and tuning under tight latency constraints.

• C++14 experience is a bonus but not essential.
