Have you ever wondered how microservices systems can be scaled vertically or horizontally to meet heavy usages? As a Performance Software Engineering Intern you will learn to create tests, test, and monitor the performance of the system's components to prevent, detect, and address performance issues. You will learn how to analyze the system's performance and collaborate with other teams to solve performance problems. You will learn what to avoid in order to create performant software. You will be working on a cloud-based open source project, FOLIO, with experienced engineers from around the world. FOLIO has gained popularity and adoption in recent years, including but not limited to the Library of Congress, MOBIUS consortium, and others.
