As a Decision Scientist, you will apply data-driven techniques to identify new opportunities, participate in project definition and prioritization and directly impact business strategy setting outcomes. There is a high expectation of proactively identifying, investigating, and resolving problems with data; designing and establishing key metrics; and the effective usage of various techniques such as statistical modeling and A/B experimentation to drive the best decisions.You will be responsible for the implementation, documentation, and on-going monitoring associated with any customer-facing decisions and risk controls you make.

Decision Scientists are not responsible for the direct development of advanced ML algorithms, but they work closely with ML teams to inform model performance evaluations.
