## About the Role

* You enjoy solving large-scale machine learning problems that directly impact millions of deliveries.
 * You have a strong sense of ownership and enjoy taking models from research through production.
 * You're comfortable working in ambiguous environments where experimentation and iteration drive product decisions.
 * You care about both model quality and production reliability.
 * You're excited to work across a diverse set of ML techniques-from neural networks and optimization to multimodal AI.
 * You collaborate well across engineering, product, and data science teams., * 5+ years of industry experience building and shipping production machine learning systems with measurable business impact (Bachelor's, Master's, or PhD).
 * Strong experience developing production machine learning models using modern deep learning frameworks such as PyTorch and distributed data processing technologies such as Spark and Airflow.
 * Experience building, deploying, monitoring, and maintaining production ML systems end-to-end.
 * Strong software engineering skills in Python and experience with modern ML infrastructure and tooling.
 * Deep expertise in at least one of the following areas:
 + Deep Learning
 + Reinforcement Learning
 + Optimization / Operations Research
 + Large Language Models (LLMs) or Vision-Language Models (VLMs)
 * Experience applying machine learning to estimation, ranking, prediction, optimization, or decision-making problems at production scale.
 * Hands-on experience with LLMs or VLMs is a strong plus.
 * Experience in logistics, marketplaces, or delivery platforms is helpful but not required.
 * Proficiency using AI-assisted development tools (e.g. Claude Code, Codex, Cursor) throughout the software development lifecycle.
 * You are located or are planning to relocate to San Francisco, CA, Sunnyvale, CA, or Seattle, WA.

## Description

As a Machine Learning Engineer on the Drive team, you'll own machine learning systems end-to-end-from feature engineering and model development to experimentation, deployment, monitoring, and continuous iteration.

Your work will span several high-impact problem areas:

 * Build next-generation machine learning models for delivery ETA, pickup ETA, merchant prep-time estimation, and order release prediction that improve reliability for merchants and consumers.
 * Develop deep learning models that leverage large-scale spatiotemporal, marketplace, and behavioral signals to improve prediction accuracy.
 * Apply reinforcement learning and optimization techniques to improve logistics decision-making, assignment strategies, and marketplace efficiency.
 * Build AI-native product experiences using large language models (LLMs) and vision-language models (VLMs). For example, transform pickup photos, item verification flows, receipts, and drop-off images into structured quality signals that help verify orders, prevent delivery defects, and improve issue resolution.
 * Design and run rigorous online experiments, production monitoring, and model iteration to continuously improve performance.
 * Partner closely with software engineers, product managers, data scientists, and platform teams to bring new machine learning capabilities into production at scale.
 * You'll have the opportunity to work across traditional machine learning, deep learning, reinforcement learning, optimization, and multimodal AI while solving some of the most challenging logistics problems at DoorDash.
