Staff Data Scientist

Zip Co Limited

9h • $192,000 - $240,000 • Remote

About The Position

Remote-first opportunity for US-based employees with the option to work in-person out of our Manhattan office. Start your adventure with Zip. As a Staff Data Scientist, you will leverage your expertise in Data Science to define, architect, build, implement and scale, new ML/AI solutions that push the next frontier of capabilities at Zip. You will be building the first generation of models that leverage rich new data sources and provide the foundation for the next generation of Zip. You will use your extensive experience, mentoring and partnering with more junior data scientists to build best-in-class ML and AI solutions. As a green field opportunity, you will be expected to independently experiment and iterate on solutions and take a test-and-learn approach to your work. You will balance short-term tangible business gains with more long-term ambitious work that together maximize the value for the business. Whatever you build, you will be expected to own end-to-end, and be responsible for communicating with business stakeholders and collaborating with engineering teams on making them work in a production environment. In addition to your extensive experience in Data Science and Financial Services, you are self-driven, intellectually curious, and comfortable iterating on simple solutions that are informed by experimental results.
