SOFTWARE ENGINEERING AT A PROPRIETARY TRADING COMPANY: OPTIVER

Summary from the TLDR Data newsletter

Optiver's platform shows what happens when latency, reliability, and ML quality map directly to P&L. Roughly 950 engineers support 10M+ daily trades across a stack spanning C++, Python, Rust, Kafka, Postgres, Databricks, custom Linux kernels, and co-located hardware. The pattern is deep infrastructure ownership, not generic speed culture.
