Job Title: Data Researcher
Duration: 12+ Months contract with extension
Location: Elk Grove, CA or Austin, TX Or Sunnyvale, CA (Onsite on every Tuesday, Wednesday, and Thursday)

About the Role
We are seeking a highly analytical Data Researcher with a strong background in Data Science, Experimental Research, and Generative AI to evaluate the effectiveness of AI-powered analytics agents.
This role is ideal for someone who enjoys applying scientific methodology to solve complex problems. Rather than simply building AI solutions, you will rigorously design experiments, evaluate AI agent performance, analyze results, and provide evidence-based recommendations on whether Generative AI can reliably answer analytical questions.
The successful candidate will combine expertise in Python, SQL, Snowflake, AI/LLM technologies, statistical experimentation, and research methodology to build reproducible experiments and measure AI system performance.

Key Responsibilities

Design, build, and evaluate Generative AI-powered analytics agents.
Develop controlled experiments to evaluate AI agent performance.
Form hypotheses and design statistically sound research methodologies.
Measure model accuracy, repeatability, reliability, and failure modes.
Analyze experimental results and communicate findings with quantitative evidence.
Evaluate different LLM configurations including prompting strategies, model parameters, RAG, and agent architectures.
Define analytical metrics and establish evaluation baselines.
Create reproducible research documentation, structured experiment logs, and technical reports.
Collaborate with Data Scientists, AI Engineers, Product teams, and business stakeholders.
Present research findings and recommendations to technical and executive audiences.

Required Qualifications

Bachelor's or Master's degree in Computer Science, Data Science, Statistics, Machine Learning, Artificial Intelligence, or a related discipline.
5+ years of experience in Data Science using:

Python
SQL
Snowflake

3+ years of experience designing and conducting controlled experiments, including:

Hypothesis testing
Experimental design
Baseline creation
Bias reduction
Statistical evaluation

3+ years evaluating ML models or AI systems using:

Error analysis
Variability measurement
Reproducibility testing
Performance benchmarking

1+ year of hands-on experience with Generative AI, including:

LLMs
Prompt Engineering
AI Agents
Retrieval-Augmented Generation (RAG)
API-based model interaction
Model parameter tuning (temperature, top-p, etc.)

Strong understanding of:

Statistical analysis
Data quality
Analytical metrics
Experimental research

Experience maintaining reproducible research documentation.
Excellent communication and presentation skills.

Preferred Qualifications

Experience evaluating Large Language Models (LLMs) for correctness, consistency, and repeatability.
Experience with Tableau or other BI/Visualization platforms.
Experience in Operations, Support, or IT Analytics.
Experience presenting research findings to leadership or executive stakeholders.
Familiarity with LangChain, LangGraph, CrewAI, AutoGen, or similar AI agent frameworks.
