Amazon.com Services LLC is seeking a Senior Applied Scientist for the Frontier AI Assets – Assessments team in Bellevue, WA. You will design automated systems to assess data quality for frontier models and develop agents that audit themselves, aiming to improve accuracy over time.

You will lead methodology design, calibration against expert judgment, and publish methods while mentoring junior scientists and communicating outcomes to product and leadership teams.

Formación

• 5+ years building ML models for business applications.
• Experience programming in Java, C++, Python or related language.
• Experience with neural deep learning methods and machine learning.
• PhD in Computer Science, Engineering, Mathematics, Statistics, Economics, or a related field.
• Experience with ML and Large Language Model fundamentals, including architecture, training/inference lifecycles, and optimization of model execution, or experience building complex software systems that have been successfully delivered to customers.
• Experience in ML, data mining, information retrieval, statistics or natural language processing, or experience designing or architecting (design patterns, reliability and scaling) of new and existing systems.

Responsabilidades

• Design the assessment methodology for frontier AI assets.
• Build the automated assessment system, from LLM-as-a-Judge baselines to agents that plan their own audits and learn from their own errors.
• Oversee the expert audit program and raise the proficiency of the auditors who run it.
• Design the measurement methods that make quality findings defensible, including sampling strategy and error analysis.
• Communicate findings to the teams that create the data and to the teams that train models and build agents using it.
• Set technical direction for assessment science, mentor junior scientists, and present results to senior leadership.
• Publish research on assessment methodology at top-tier venues and contribute to patents.

Senior Applied Scientist, Frontier AI Assets - Assessments (FAI)

Job ID: 10567940 | Amazon.com Services LLC

Amazon's Artificial General Intelligence (AGI) organization builds frontier models and the AI agents on top of them, and every one of them depends on data we can trust. The Frontier AI (FAI) Assessment team owns the science of dataset quality - for the data that trains frontier models, and for the benchmarks that determine whether a model or an agent actually works.

In this role you will build the automated systems that make quality assessment at scale. Large language model (LLM)-as-a-Judge is the starting point, and our goal is to develop an agentic system that plan its own audits, critiques its own judgments, and improves its own accuracy over time. You will design it, calibrate it against expert human judgment, and set the technical direction for how the organization measures data quality.

Key job responsibilities

• Design the assessment methodology for frontier AI assets
• Build the automated assessment system, from LLM-as-a-Judge baselines to agents that plan their own audits and learn from their own errors
• Oversee the expert audit program and raise the proficiency of the auditors who run it
• Design the measurement methods that make quality findings defensible, including sampling strategy and error analysis
• Communicate findings to the teams that create the data and to the teams that train models and build agents using it
• Set technical direction for assessment science, mentor junior scientists, and present results to senior leadership
• Publish research on assessment methodology at top-tier venues and contribute to patents

A day in the life

• Train AI agents to assess the quality of datasets and evaluation benchmarks, and document where they fall short
• Diagnose their failures and improve the models, rubrics, and calibration behind them
• Review the quality reports that auditors and agents produce, and decide whether the conclusions hold
• Coach expert auditors and junior scientists, and move more of the manual audit work into automation
• Lead research on self-improving assessment agents, from open problem to publication

About the team

FAI Assessment is part of Frontier AI Assets in AGI. We assess the quality of the datasets and benchmarks behind Amazon's frontier models and agents, and we define what good data means. Today that work relies on human-in-the-loop review by domain experts. Our aim is to automate it with self-improving agents that experts keep calibrated. We are a small team of scientists working closely with the data, modeling, and agent teams.

Basic Qualifications

• 5+ years of building machine learning models for business application experience
• Experience programming in Java, C++, Python or related language
• Experience with neural deep learning methods and machine learning
• PhD in Computer Science, Engineering, Mathematics, Statistics, Economics, or a related field
• Experience with Machine Learning and Large Language Model fundamentals, including architecture, training/inference lifecycles, and optimization of model execution, or experience building complex software systems that have been successfully delivered to customers
• Experience in machine learning, data mining, information retrieval, statistics or natural language processing, or experience designing or architecting (design patterns, reliability and scaling) of new and existing systems

Preferred Qualifications

• Working knowledge of the public benchmarks used to evaluate frontier AI models and agents, and of their limitations
• Experience designing large-scale human data collection and improving the quality of the datasets
• Experience with the data pipelines behind model post-training and alignment
• Experience in developing recursive self-improving agents based on frontier LLMs
• Publication record at top-tier machine learning venues such as ICML, ICLR, CVPR, NeurIPS, AAAI, EMNLP, Interspeech, ICASSP
• Experience in an academic research or teaching position, such as professor, lecturer, or postdoctoral researcher
