Principal Engineer, Long Term Planning and Forecasting

LTPF owns the demand forecasts and long-term plans that drive Amazon's top-line, capacity investments, working capital, and network topology decisions worldwide. Our outputs are reviewed by Stores and Operations leadership up to the CEO level, and they set the terms for billions of dollars in capex.

We are looking for a Principal Engineer to own the technical architecture that makes that possible. You will set the engineering direction across unified forecasting, coordinated planning system, and GenAI agentic insights platform. You will drive tech primitives, standardized and auditable outputs, and self-service interfaces.

Key job responsibilities

1. Own the technical architecture across systems. Drive simplification and establish the primitives and the migration path for the legacy systems.
2. Set and hold the engineering bar in design reviews across science, engineering and product.
3. Drive AI adoption as engineering infrastructure, including agentic tooling, skills, and spec-driven development practices that change how the org builds, and make the productivity gains measurable.
4. Partner across supply chain functions, operations, and Finance to drive system simplification and efficiency.
