Applied Scientist II, Demand Science

The Amazon Devices & Services Demand Science (DSci) team is seeking a scientist with strong AI/ML and communication skills to help with demand forecasting and supply optimization for the entire Amazon device family of products, services, and accessories. Amazon Devices represents a highly complex space with 100+ products across several product categories (e‑readers, tablets, TV, smart speakers and audio assistants, wifi routers, and video doorbells and cameras), for sales both online and in offline retailers globally.

We develop scalable and robust state‑of‑the‑art ML, AI, and automation solutions — including transformer‑based forecasting architectures, large language model (LLM)-powered agents, and agentic AI workflows — that learn from diverse data sources and power advanced predictive models. With better forecasts we drive down supply chain costs, enabling the offer of lower prices and better in‑stock selection for our customers.

In this role, you will own the full lifecycle — from research through production deployment. You will drive end‑to‑end solutions: understanding business requirements, exploring large‑scale historical data and ML models, building prototypes, developing conceptually new approaches (including AI‑native experimentation and agent‑driven automation), and partnering with engineering teams to deploy and maintain solutions in production. You will collaborate closely with scientists, engineering peers, and business stakeholders, at the heart of a growing & exciting focus area for Amazon Devices and Services where AI is transforming how we forecast, validate, and optimize decisions.

You are an individual with strong science abilities, excellent communication skills, solid coding skills, and comfort with modern AI tools and frameworks. You will be responsible for researching, prototyping, experimenting, analyzing predictive models, implementing production‑ready solutions, and developing AI‑driven automation that reduces manual intervention and enables hands‑off science operations.

• Build forecasting models from prototype through production, working closely with engineering to deploy at scale
• Find and integrate new data sources to improve forecast accuracy and coverage
• Design and deliver production‑ready solutions for business‑critical forecasting and optimization problems
• Define and track performance metrics — both technical (error rates, bias, coverage) and business (plan attainment, financial impact, reduction in manual overrides)
• Write and maintain clear technical documentation; present findings and recommendations to scientists, engineers, and business leaders
• Set team standards for methodology, code quality, experimentation rigor, and AI‑assisted workflows

We are a focused science team looking for help with enhancing the demand forecasting framework we’re building and figuring out how to best solve the needs of both our internal stakeholders and cross‑functional partners.

• 4+ years of building models for business application experience
• PhD, or Master’s degree and 4+ years of CS, CE, ML or related field experience
• Experience programming in Java, C++, Python or related language
• Experience in state‑of‑the‑art deep learning models architecture design and deep learning training and optimisation and model pruning
• Experience in building machine learning models for business application

• Experience using Unix/Linux
• PhD in computer science, machine learning, engineering, or related fields
• Experience in any of the following areas: transformer model architectures (e.g., TFT, foundation models), neural network / deep learning model fine‑tuning and development.
