Job Overview
Job description provided by G-Research.
G-Research is hiring a C++ Software Engineer in London to join its Colo Engineering and Performance team.
The team owns system-level application performance in the firm's colocation sites, giving developers insight and recommendations for improvement.
The engineer will develop high-performance, low-latency systems and collaborate closely with quantitative researchers and developers.
They will design and optimise rapid trading systems end to end, applying low-level systems programming and optimisation using languages such as C and C++.
The role also involves analysing and improving application performance using hardware counters and other profiling tools.
Candidates need expertise in low-level systems programming and optimisation for extremely low-latency, high-throughput network applications.
A deep understanding of modern computer architecture, including cache hierarchies of modern processors, is required, as is experience with fast-packet processing in user space.
Financial market knowledge is not required for the role, and experience optimising performance in managed runtime languages such as C# is desirable.
