About this role

Alpaca seeks a Senior Data Scientist for AI Evaluation to design measurement systems for models and agents operating remotely across the Americas. This remote position suits an experienced quantitative professional who wants to establish a greenfield evaluation practice at a global financial technology infrastructure provider.

Role Overview

Alpaca is hiring a Senior Data Scientist, AI Evaluation to operate as a senior individual contributor establishing the quality bar for models and agents. The person in this role will turn ambiguous quality questions into concrete scoring methods, ground truth definitions, and automated evaluation loops. Working independently from the teams building the systems, this practitioner will leverage an existing data foundation to enhance overall quality and accelerate safe system releases while partnering closely with product, engineering, and analytics engineering teams.

Key Responsibilities

Design AI evaluations by establishing clear metrics, ground truth, and scoring methods for models and agents
Build repeatable evaluation loops to monitor quality over time and prevent regressions prior to deployment
Collaborate with engineering and analytics engineering to operationalize evaluation harnesses
Translate evaluation findings into actionable recommendations for system enhancements
Formulate quality standards, comprehensive documentation, and review practices
Mentor colleagues on evaluation best practices and foster a measurable AI quality culture

Requirements

Possess 6 to 10 years of professional experience in quantitative data science or machine learning, focusing specifically on measurement or evaluation
Demonstrate a strong statistical and machine learning background, treating evaluations as experiments using sample sizing, confidence intervals, significance, and non-determinism management while validating automated graders against human ground truth
Exhibit proficiency in Python and SQL alongside practical experience evaluating models in production settings
Apply strong judgment when defining quality metrics and ground truth for ambiguous outputs
Maintain excellent communication and cross-functional collaboration abilities to align technical teams and leadership
Display strong problem-solving capabilities within fast-paced, greenfield environments

Nice to Have

Hands-on experience with LLM and agent evaluation in production, covering evaluation harnesses, LLM-as-judge calibration, and CI regression gates
Prior work evaluating text-to-SQL, analytics agents, or alternative systems featuring verifiable correctness against data
Background working within fintech, brokerage, or related sectors where incorrect answers carry real business or risk consequences
Familiarity with AI tools utilized across research and engineering workflows
Holding a quantitative degree is considered a plus, though equivalent industry experience is equally welcomed
