The ideal candidate would be equally comfortable guiding the development of models to rank tweets and predict engagement, whiteboarding new product ideas with designers and product managers, or brainstorming ways to efficiently index and serve tweets with systems engineers.

Who You Are:

  • You have a background in machine learning, ideally prediction/binary classification, logistic regression, decision trees, deep learning techniques
  • You have familiarity with A/B experiments and metrics
  • You have enthusiasm for experiment and metrics-driven iterative product development
  • You can hold your own technically with engineers on the team and give constructive feedback on projects and ideas
  • You have a sense of urgency, move quickly and ship things
  • You can partner with other leads from engineering, product and design to craft a roadmap and measures of success
  • You can be a bold source of engineering talent and will be comfortable closing candidates
