Applied Scientist III, Demand Technology, Amazon Demand Side Platform, Bravo Non-endemic
Applied Scientist III, Demand Technology, Amazon Demand Side Platform, Bravo Non-endemic at Amazon scores 90 out of 100 on AI centrality, which makes it a Level 4 role on this board.
AI in this role
Own the applied science roadmap and machine learning models for conversion prediction, ranking, and measurement on the Demand Side Platform.
Key job responsibilities
- Own the applied-science roadmap for one or more non-endemic performance workstreams — from problem framing and experiment design through offline validation, online experimentation, and production launch.
- Design and improve machine learning models for sourcing, ranking, and response prediction that optimize toward advertiser outcomes such as cost per acquisition and return on ad spend.
- Define measurement methodology — including incrementality, weighted conversions, and off-Amazon attribution — that correctly values an impression when the conversion happens outside Amazon.
- Partner with engineering, product, and sales-facing teams on deep dives into real enterprise advertiser accounts, turning account-level learnings into scalable model and system improvements.
- Mentor scientists and engineers across the organization, publish internal best practices, and contribute to the broader scientific community through peer reviews and publications.
A day in the life
You might start your morning analyzing offline experiment results for a new conversion-prediction model, then join a design review with engineers on how to serve that model in the real-time bidding pipeline. After lunch launch, you could be working with a product manager to define success metrics for a non-endemic advertiser segment, followed by a code review for a teammate's feature-engineering change. You regularly carve out time to read recent research on causal inference or data-efficient learning and assess whether new techniques could improve your team's models.
About the team
We are a lean team of applied scientists and software development engineers within Amazon DSP, focused on strategic initiatives that have not had significant investment before. We work close to the customer — partnering directly with product and sales-facing teams to understand advertiser needs and translate them into scalable scientific solutions. If you want to shape the direction of a high-priority problem space where your ideas move quickly from whiteboard to production, we would love to hear from you.
Basic qualifications
- 3+ years of building machine learning models for business application experience
- PhD, or Master's degree and 6+ years of applied research experience
- Experience programming in Java, C++, Python or related language
- Experience with neural deep learning methods and machine learning
Preferred qualifications
- Experience with modeling tools such as R, scikit-learn, Spark MLLib, MxNet, Tensorflow, numpy, scipy etc.

Skills and AI tools this role asks for
Questions you could be asked
- Tell me about a project where machine learning was part of your work. What did you do?
- Tell me about a project where causal inference was part of your work. What did you do?
- Tell me about a project where experiment design was part of your work. What did you do?
- Tell me about a project where python was part of your work. What did you do?
- Tell me about a project where modeling was part of your work. What did you do?
Adapt your resume
- List these exact terms on your resume: Machine Learning, Causal Inference, Experiment Design, Python, and Modeling. An applicant tracking system matches the wording, not the idea.
- Attach one line of real, concrete experience to at least one of them — a tool named with nothing behind it rarely survives a human read.
- Lead with what you built, trained or shipped — this role is judged on the AI system itself, not the tools around it.
