The Mission

Your mission as Staff/Principal Engineer is to drive the improvement of the platform, making the product extremely fast, scalable, reliable and easy to operate. The results will be directly reflected in the fraud prevention metrics, dependent business variables (revenue, margin) as well as valuation of the company and your personal stock option pool. Your code will be used to process data from more than 50M devices, creating decisions within milliseconds on top of thousands of events per second.

You will collaborate with backend engineers, founders, product managers, research team
(building the ML/AI models), platform team and other fraud-fighters in the company.
