Linux and networking

Why does Linux and networking matter in quant?

Deep Linux and networking knowledge is a standing requirement across trading engineering: kernel tuning, NIC behaviour, multicast market data and the measurement tooling around them.

Network engineering now appears in a large share of trading infrastructure postings, reflecting how much of the remaining latency budget sits in the network rather than in application code.

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.
