Strong knowledge of statistics, experimentation and machine learning, including regression, hypothesis testing, experimental design, feature engineering, model selection and evaluation.
Experience working with modern cloud data platforms, such as Snowflake, and the ability to structure and solve complex or ambiguous problems.
Clear communication, planning and collaboration skills, with the ability to work independently and partner effectively with Data Science, Engineering, Product and business teams across locations, time zones and changing priorities.
Additional Experience That Would Be Valuable:
Experience with generative AI and large language model applications, including embeddings, retrieval-augmented generation (RAG), vector search or prompt engineering.
Knowledge of deep-learning techniques or experience working with large-scale datasets.
Experience developing analytical solutions into repeatable products, capabilities or business processes.

Questions you could be asked
- How do you structure and test a prompt to get consistent output from a language model?
- How would you design a retrieval step so the model answers from real data instead of guessing?
- Tell me about a project where machine learning was part of your work. What did you do?
- Tell me about a project where data science was part of your work. What did you do?
- Tell me about a project where statistical analysis was part of your work. What did you do?
Adapt your resume
- List these exact terms on your resume: Prompt engineering, RAG, Machine learning, Data Science, and Statistical Analysis. An applicant tracking system matches the wording, not the idea.
- Attach one line of real, concrete experience to at least one of them. A tool named with nothing behind it rarely survives a human read.
- Lead with what you built, trained or shipped. This role is judged on the AI system itself, not the tools around it.
