I worked there as a software engineer a bit over a year from the beginning of 2020.

My two cents:

I really liked the people there, how work is structured into cross-functional teams, learned a ton about biology and felt doing something useful (was part of the team whose work resulted in 2 novel targets in AstraZeneca's portfolio that were derived by AI-enabled target identification process).

There is definitely potential to create something impactful, but I was not really considering them an EA organization myself (compared to CEA, Open Phil and smilar).
