Full Job Description
Key job responsibilities

Design and build causal predictive models that move beyond correlation - developing systems that forecast workforce outcomes and identify the actionable drivers behind them, enabling leaders to intervene before problems materialize

Pioneer novel feature engineering by bringing creative approaches from LLMs, computer vision, and other emerging techniques into the causal modeling pipeline, unlocking signal that traditional econometric and tabular methods miss

Write production-quality science code that your partner engineering team can implement directly into operational decision-making tools - your work must be clean, well-documented, and built to scale

Bridge disciplines by translating between economists, data scientists, and engineers - synthesizing causal rigor with ML innovation to produce models that are both scientifically defensible and operationally useful

Design and execute experiments to validate causal claims and model performance, establishing evaluation standards that the team and stakeholders trust

Develop and elevate peers across the team - mentoring scientists in adjacent disciplines, sharing technical knowledge, and raising the collective bar on modeling and engineering practices

Present findings to senior leadership, distilling complex causal and predictive insights into clear recommendations that drive workforce strategy for Amazon's Tier 1 hourly populations.
