Do you want to join an innovative team applying machine learning, advanced optimization techniques, and Large Language Models (LLMs) to transform the delivery of heavy and bulky items for Amazon customers? Are you excited about working with large-scale operational data and developing models that solve real-world logistics and fulfillment challenges? If so, the Amazon Extra Large (AMXL) Science team may be the right fit for you.
AMXL is Amazon's specialized business for delivering heavy and bulky items, including appliances, furniture, fitness equipment, and mattresses, with a premium customer experience that includes room-of-choice delivery, at-home installations, and assembly services. We are seeking an Applied Scientist to help develop scalable machine learning and optimization solutions that improve delivery efficiency, capacity planning, network design, and customer experience across our rapidly growing network.
In this role, you will partner with senior scientists and engineers to translate complex operational problems into data-driven solutions, build and evaluate models, and contribute to next-generation fulfillment and logistics systems.

Key job responsibilities

Apply machine learning, statistical techniques, time series modeling, and operations research to build and improve models for delivery routing, capacity planning, demand forecasting, workforce scheduling, and network optimization

Analyze large-scale historical and real-time operational data to identify efficiency patterns, bottlenecks, and emerging trends across the AMXL network

Develop, validate, and deploy innovative models under the guidance of senior scientists to improve cost-to-serve and customer experience

Experiment with emerging technologies, including Generative AI and LLMs, to enhance automation, scheduling, and operational decision-making

Collaborate closely with software engineers to implement models in real-time production systems

Partner with operations, product, and business teams to translate operational insights into actionable improvements

Build scalable, automated pipelines for data analysis, model training, and validation

Monitor model performance and provide clear reporting on key operational and business metrics

Research and prototype new modeling approaches to improve system performance and delivery quality

A day in the life

You will be working within a dynamic, diverse, and supportive group of scientists who share your passion for innovation and excellence in logistics and fulfillment science.
You will work closely with business partners, operations teams, and engineering teams to create end-to-end scalable machine learning solutions that address real-world challenges across AMXL's heavy and bulky delivery network, including demand forecasting, capacity planning, routing optimization, and customer experience improvement.
You will build scalable, efficient, and automated processes for large-scale data analyses, model development, model validation, and model implementation in production systems.
You will also provide clear and compelling reports on your solutions to both technical and non-technical stakeholders, and contribute to the ongoing innovation and knowledge-sharing that are central to the team's success.
