# Roles {% embed url="" %} Roles - ML Teams {% endembed %} ## Summary * The **Machine Learning Product Manager** is someone who works with the Machine Learning team, as well as other business functions and the end-users. * This person designs docs, creates wireframes, comes up with the plan to prioritize and execute Machine Learning projects. * The role is just like a traditional Product Manager, but with a deep knowledge of the Machine Learning development process and mindset. * The **DevOps Engineer** is someone who deploys and monitors production systems. * This person handles the infrastructure that runs the deployed Machine Learning product. * This role is primarily a software engineering role, which often comes from a standard software engineering pipeline. * The **Data Engineer** is someone who builds data pipelines, aggregates and collects from data storage, monitors data behavior. * This person works with distributed systems such as Hadoop, Kafka, Airflow. * This person belongs to the software engineering team that works actively with Machine Learning teams. * The **Machine Learning Engineer** is someone who trains and deploys prediction models. * This person uses tools like TensorFlow and Docker to work with prediction systems running on real data in production. * This person is either an engineer with significant self-teaching OR a science/engineering Ph.D. who works as a traditional software engineer after graduate school. * The **Machine Learning Researcher** is someone who trains prediction models, but often forward-looking or not production-critical. * This person uses TensorFlow / PyTorch / Jupiter to build models and reports describing their experiments. * This person is a Machine Learning expert who usually has an MS or Ph.D. degree in Computer Science or Statistics or finishes an industrial fellowship program. * The **Data Scientist** is actually a blanket term used to describe all of the roles above. * In some organizations, this role actually entails answering business questions via analytics. * The role constitutes a wide range of backgrounds from undergraduate to Ph.D. students. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
