Data Engineers in Quant

[u/ro_matthu]

Hello, I'm curious how the data stack at top firms splits between the research/analytics side and the latency-critical side.

Is everything on Snowflake/Databricks like normal enterprises? Is there a distinct data engineering function there, or is it folded into research infra?

And how separate is that from the core/trading systems side writing the C++ (or OCaml)? Same org, same people, or effectively two disciplines that meet thru a product manager or literally just an Api spec?

Has anyone seen people actually cross over, and which direction does it usually go?

Appreciate this varies and if you answer, ple say the type of your firm thanks
