Technology, Information and Internet San Jose, CA 10,001+ employees Public Company

eBay operates a massive distributed commerce platform serving millions of sellers and buyers across 190+ markets, built on a polyglot stack spanning Java, C#, Python, Kafka, and cloud data warehouses (BigQuery, Snowflake). The hiring surge is heavily weighted toward engineering (90 roles) and product (42 roles), with active adoption of streaming (Kafka), modern identity protocols (OAuth 2.0, SAML 2.0, passkeys), and AI-enabled transformation — indicating a shift toward real-time commerce features and seller intelligence at scale. Pain-point clustering around reliability, data governance, and seller onboarding suggests infrastructure maturation efforts as core priorities.
