Job Specifications

Low Latency C++ Engineer - Market Data Systems - 6-12 month contract

I am hiring contractors 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.
Available immediately.
