At ServiceNow, our mission is to “make the world of work, work better for people,” and our AI-driven platform is delivering on that promise. We're the #1 enterprise platform for uniting AI, data, and workflows — simplifying how people work, automating what slows them down, and enabling seamless, impactful experiences.  About the Role — Senior Staff Data Platform Software Engineer, Data Access Team   Every workflow, AI agent, and application on the ServiceNow AI Platform depends on one thing: getting the right data, fast, correctly, and securely. As part of the Persistence organization, you'll build the layer that makes that possible, the foundation under a platform that 85% of the Fortune 500 runs their business on. You'll help: Give developers and customers faster, more reliable, more secure access to the data platform they build on Push the limits of IO, transactions, and concurrency across relational, time-series, and columnar engines Turn hard infrastructure problems into simple capabilities and automation for the developers and customers who build on the platform About the Team   The Data Access team owns the ServiceNow ORM and data access layer. We take the platform's logical object model and translate every data request into high-performance queries against many database engines, including our homegrown RaptorDB (PostgreSQL), MariaDB, Oracle, and Trino, graph databases, and time-series databases. Our home-grown SQL generation engine, table management, and database metadata services are what let application developers build powerful applications across industries without ever having to manage engine complexity. That makes us one of the most leveraged teams in the company. A single improvement to our engine speeds up thousands of applications and millions of queries, and getting it wrong is not an option.
