Pros
The culture is healthy, balanced and welcoming. It's a great size where it's not so small that everything feels hectic and tenuous, but it's not so big that it's impossible to do something that feels valuable. The science problems are diverse, require you to keep on top of the field, and push you to think outside of the box. If you like problem solving with data, you'll love Valkyrie!
Cons
This isn't a super cushy large tech company where they do your laundry and give you free lobster for lunch (though we have great benefits). I like that it's more of a scrappy place, but if you want a data science job where you throw your models to an engineer to finish the implementation, or you only want to deal with straightforward, clean data, it's probably not a good fit.
