I’ll echo @erp12 on this. If you look for jobs that are heavy in spark and/or scala, you’re likely to find more FP minded teams. Python may still be the primary language used, but there will often be opportunities to use other languages as well.
I used to work in https://www.agoda.com/, and they have a big data science and engineering team. The main stack is Spark + Scala with a big emphasis on FP. Perhaps the only exception was developing deep learning algorithms, which was done in Python.
