Low-latency systems
Why does Low-latency systems matter in quant?
Low-latency engineering is the discipline of removing microseconds from the path between market data arriving and an order leaving: kernel bypass, busy polling, NUMA awareness, careful allocation and relentless measurement.
This is a measurement culture as much as a coding one. Candidates who can describe how they profiled a system, what they found and what the change was worth interview far better than those who list techniques.

Methodology
Figures are expressed as annual total compensation (base salary plus expected performance bonus) in the reference market's local currency, converted from a US dollar base. They describe typical market ranges rather than any individual offer, and exclude sign-on payments, deferred equity and carried interest. Portfolio-manager figures reflect formulaic profit-share arrangements and are therefore far more dispersed than any other role.

Modelled bands describe the market, not an individual offer. Where an employer states pay, the stated figure is used and labelled as such.
