- A leading technology or quantitative firm (such as FAANG+, Magnificent 7+, top-tier quant funds or equivalent) with a Mid-senior level title. Applied Scientist, Research Scientist and Machine Learning Engineer/Scientist roles also qualify.
- A top financial institution (a leading bank, hedge fund or trading firm)
- A top-tier consulting firm, working as a data scientist
- A Fortune 100 company, with a senior or manager-level title
- Experience may be split across more than one qualifying employer
- Strong command of Python, SQL, statistical modeling, machine learning, experimentation and causal inference
- Proven ability to turn messy real-world data into rigorous analyses and reliable pipelines
