I interviewed for a data science job there & the team of engineers seemed really unhappy. They reported into the director of operations, which is a weird place for data science to report, and the managers I met definitely viewed it as a paranoid cost center kind of thing.
Also in the interview process I recall that Digital Ocean made a very low offer and refused to discuss negotiating it. Seemed clear that cheap hires were mandatory for data science / machine learning.
I wouldn’t be surprised if this lack if investment meant that some data science intern or bootcamp grad is designing this automatic fraud shut down system, and that there’s a glaring lack of investment in professional usability for a system like that.
