Applied Scientist II, Demand Enablement, Product Analytics and Operations

In this role you will design and build intelligent multi-agent systems that automate root cause analysis for advertising campaign delivery at scale. You will architect agentic orchestration patterns where specialized sub-agents (campaign diagnostics deal-level troubleshooting pacing control) are invoked as composable tools by a reasoning layer that determines which subsystems to query based on the nature of the issue. You will develop hierarchical analysis frameworks that move from daily trend detection to intra-day anomaly isolation enabling the system to pinpoint when and why delivery degraded rather than relying on static time windows. You will build self-learning feedback loops where the system identifies recurring failure signatures (auction dynamics pacing anomalies supply contention) updates its diagnostic knowledge as engineering teams deploy fixes and retires stale patterns automatically. We are looking for a passionate Applied Scientist with technical expertise in LLM-based agent architectures retrieval-augmented generation time-series anomaly detection and production ML addition to hands-on experience building agentic AI solutions an ideal candidate should demonstrate the ability to translate complex distributed system behaviors into structured diagnostic reasoning show a willingness to push the boundaries of how LLMs interact with real-time operational data and thrive in an environment where you ship production systems that directly reduce advertiser escalation time from days to minutes.

Key job responsibilities
* Conduct deep data analysis to derive insights for the business identify gaps and uncover new opportunities.
* Develop scalable and effective machine learning models and optimization strategies to solve business problems.
* Run regular A/B experiments gather data and perform statistical analysis to optimize advertiser experiences.
* Collaborate closely with software engineers to deliver end-to-end solutions into production.
* Enhance the scalability efficiency and automation of large-scale data analytics model training deployment and serving.
* Research and implement new machine learning models and techniques to improve advertising performance.

A day in the life
Your primary focus is building a multi-agent diagnostic system that automates root cause analysis for advertising campaign delivery issues. On a typical day you might review how the system handled recent escalations identify where it reasoned incorrectly adjust orchestration logic and write new evaluation cases. You will design agent architectures that invoke specialized sub-agents as tools build hierarchical analysis frameworks that move from trend detection to anomaly isolation and develop self-learning loops that keep the systems diagnostic knowledge current as the underlying platform evolves. You will work closely with SDEs building the diagnostic platform product managers defining the troubleshooting experience and the support teams who rely on your system to resolve advertiser delivery issues in minutes instead of days. Beyond the core agent work you may find yourself diving into causal inference to measure recommendation effectiveness prototyping proactive anomaly detection or contributing to evaluation science for systems that reason over complex operational data.

About the team
The Demand Enablement Product Analytics and Operations team builds the diagnostic and intelligence layer for Amazon DSP the demand-side platform powering Amazons programmatic advertising business. We own the systems that detect diagnose and surface delivery issues across campaigns giving internal teams and advertisers the visibility to act before problems impact spend. Our product portfolio spans automated troubleshooting platforms advertiser-facing delivery insights and AI-powered root cause analysis using multi-agent architectures on foundation models. We are a small high-ownership team that ships production systems end-to-end from data pipelines processing billions of bid events to LLM-based agents that reason over complex advertising systems. If you want to work at the intersection of applied science distributed systems observability and real business impact measured in advertiser dollars recovered this is the team.
