Sr Staff Software Engineer

ServiceNow•San Diego, CA

About The Position

We're seeking a senior technical leader to shape the future of ServiceNow's developer experience. You'll work on the ServiceNow IDE—a web-based VSCode fork that serves as the foundation for our Build Agent, an agentic AI product that empowers and enhances developer productivity. This is a full-stack role (Java backend, TypeScript frontend) where you'll architect and build core features that directly impact how thousands of developers build on the ServiceNow platform. You'll own significant technical initiatives end-to-end, set engineering standards for the team, and work cross-functionally with design, product, and AI teams to define what modern AI-assisted development looks like. You'll be both a hands-on engineer diving deep into complex technical challenges and a strategic leader who keeps the bigger picture in focus—driving outcomes, not just deliverables. This role requires someone who leads by example, takes ownership beyond their immediate scope, and is energized by building developer tools that multiply the impact of others across the platform.
