In this role you’ll be a part of a team of software engineers that design and develop the software stack that enables these user experiences. You will play an integral part in ideating new algorithms and models that would unlock new experiences or improve accuracy and performance of existing ones. You will work with other members of the team to design pipelines that yield the data needed to train and refine your algorithms and models.You will ensure product quality by developing and improving tooling (including internal iOS applications), continuous integration, and data analysis and visualization. You will communicate with cross-functional teams and leadership about your designs, your progress and any risks that you see. You’ll test your work, dogfood it, collect metrics, and iterate.
