About The Position

TCGplayer, an eBay company, powers a marketplace for buyers, sellers, hobby shops, and collectors across the trading card community. For many people, TCGplayer is more than a marketplace. It is part of how they discover, enjoy, and stay connected to the hobby they love! The Data Engineering team helps make that experience possible by building the systems, standards, and partnerships that make data easier to trust, easier to work with, and easier to scale across TCGplayer Technology. As a Staff Data Engineer, you will join our Data Engineering team and server as a technical leader, helping shape technical direction across warehouse and application-facing systems. You will work closely with engineering, platform, and analytics teams to strengthen data governance, improve confidence in data-related changes across distributed environments, and guide sound decisions around datastores, data movement, and system design. This is a highly collaborative Staff Data Engineer role with broad influence across TCGplayer, with the opportunity to raise engineering standards, support long-term platform health, and help teams build with greater clarity and confidence.
