Candidates should have at least one semester/quarter left of their education after finishing the internship

Preferred Qualifications

Strong foundation in statistics, machine learning, optimization, economics, analytics, experimental design, and causal inference, with experience applying these methods to solve complex business problems

Experience with exploratory data analysis, statistical modeling, experimentation, and model development

Proficiency in SQL and familiarity with programming languages such as Python and/or R

Demonstrated problem-solving skills, analytical rigor, and a research-oriented mindset, with the ability to drive projects from ideation and experimentation through prototyping, implementation, and deployment

Interest in operating as a full-stack Applied Scientist, taking ownership of the end-to-end solution lifecycle and collaborating closely with cross-functional technical and business stakeholders

Excellent communication skills, independence, and strong execution, with a bias toward action and a track record of delivering results

Interest in software engineering fundamentals and productionizing analytical solutions, including familiarity with tools and concepts such as ML web applications (e.g., Streamlit, Flask), real-time databases, distributed computing frameworks (e.g., Spark, Ray), and modern AI/LLM frameworks (e.g., Hugging Face Transformers, LangChain)
