IES Payments is building a first-of-its-kind Economic Profit (EP) framework to measure the full economic value of Amazon Payment Products (APPs) and payment-led promotional levers across 9 emerging markets. Today, program leaders cannot credibly quantify the total value their products create beyond direct revenue contribution — EP changes that. We are looking for an Economist who will own the incrementality science that underpins this framework. You will design, evolve, and defend the econometric methodologies that measure how payment instruments create value — within the transaction (Day-0) and over the 365-day customer lifetime (DSI). You will be the single-threaded science owner for how we compute and justify incrementality across always-on instruments, promotional constructs, weblabs, and behavior-change programs. This is not a support role. You will directly shape how Amazon measures the ROI of its payment investments across IES — and your work will feed into S-Team level planning and investment decisions. Key job responsibilities What You'll Do Incrementality Methodology — Design & Evolve ● Own end-to-end design of incrementality computation logic across EP use cases: always-on APPs, one-time promotions, weblab measurement, and ongoing behavior-change programs (e.g., UPI adoption rewards) ● Evolve the Day-0 incrementality methodology — the novel component that captures value created within the current transaction itself, where standard DSI excludes the event day ● Design econometric approaches for use cases where GCCP fails (weblabs with instrument dynamics) and where traditional promo measurement breaks down (investment-phase → payoff-phase programs) ● Develop and validate proxy logic for segment-wise EP cuts in the absence of dedicated compute infrastructure CBA & Cross-Functional Alignment ● Lead the formal methodology defense with CBA V-Team — every surrogate, every computation, every modification to Watson's default workflow requires rigorous scientific justification and CBA sign-off ● Align with DEX and Stores Finance on the science behind cost-to-serve incrementality metrics (CoP avoidance, UPB savings, CoBW reduction) ● Navigate the surrogate onboarding challenge: new payment surrogates can cannibalize value currently attributed to existing Marketplace HVAs — you will need data-backed arguments to bring Stores leadership on board, not just science correctness ● Build and maintain the defensibility of EP methodology against internal scientific scrutiny Partnership with Data Science ● Work hand-in-hand with the EP Data Scientist to build a holistic case for payment HVA incrementality — you bring the econometric logic, they bring the predictive model justification; both must align for CBA acceptance ● Jointly defend surrogate onboarding proposals where the economist provides the causal framework and the data scientist provides the feature-level model evidence ● Translate econometric findings into business narratives for VP+ leadership reviews Geographic Expansion ● Adapt and calibrate EP methodology for Brazil, Mexico, MENA, and APAC markets — each with distinct instrument mixes, data maturity levels, and marketplace economics ● Determine where the India-built methodology transfers cleanly and where market-specific econometric adaptations are needed About the team Our team is dedicated to applying economic thinking to some of Amazon's most impactful business questions. We bring together economists with expertise spanning causal inference, structural modeling, and applied microeconomics to deliver insights that guide long-term strategy. We value intellectual rigor, open debate, and a collaborative spirit that makes everyone stronger. We are building toward a future where economic analysis is deeply embedded in decision-making at every level. If you want to work alongside thoughtful, curious colleagues and see your work shape how Amazon operates, this is the team for you.

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.
