C++ Feed Handler Engineer

Low Latency C++ Engineer – Market Data Systems

I am hiring for a team building the fastest market data platform on the planet.

They operate at the bleeding edge of C++ engineering, systems architecture, and real-time financial data. Their software ingests, decodes, and distributes live market data from global exchanges, with latencies measured in single-digit microseconds.

Engineers in this team work in an environment where:

• C++ is pushed to its absolute limits – with attention to every CPU cycle and cache line.
• Latency is key; performance is benchmarked and obsessively tuned.
• Code goes live in globally distributed systems supporting elite quantitative strategies.
• Engineers drive technical direction: from architecture to tooling to micro-optimisations.

Technologies in use include:

• Modern C++ on bare-metal Linux.
• Userspace networking, NUMA-aware memory design, lock-free data structures.
• Custom profiling and telemetry tools.
• Aeron, Kubernetes, and whatever else delivers speed and stability.

Ideal candidates will bring :

• A proven track record building ultra-low latency systems – in finance, gaming, telecoms, or similarly demanding domains.
• Deep systems-level knowledge, including performance tuning, concurrency, and CPU/memory architecture.
• An good eye for elegant, high-performance design.
• The ability to take ownership, work independently, and deliver high-grade and production-ready code.

I want to speak to engineers who build systems that move faster than thought.
