We're looking for an experienced Vendor Relationship Manager / Market Data Analyst to join our Data Vendor Management team. This team forms and manages our relationships with various financial market data vendors and exchanges while partnering directly with traders, researchers, and internal stakeholders to identify and assess the data requirements that drive our trading strategies. You will be responsible for negotiating new contracts and ongoing contract renewals and maintaining the inventory management platform for our contracts, including the cost structure for each. You will also help with usage reporting and audits to ensure that our team continues to best meet the firm's needs. Managing this correctly requires working with several teams across Jane Street, including Legal, HR, Engineering, Accounting/Finance, and other business areas, to ensure that new contracts are fully understood and vetted, invoices are processed on time, and colleague requests for new data vendors and services are heard and considered.
