Sr Staff Software Engineer

Company Description
It all started in sunny San Diego, California in 2004 when a visionary engineer, Fred Luddy, saw the potential to transform how we work. Fast forward to today - ServiceNow stands as a global market leader, bringing innovative AI-enhanced technology to over 8,100 customers, including 85% of the Fortune 500®. Our intelligent cloud-based platform seamlessly connects people, systems, and processes to empower organizations to find smarter, faster, and better ways to work. But this is just the beginning of our journey. Join us as we pursue our purpose to make the world work better for everyone.
Job Description
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.
