She cried tears of joy. That moment inspired Fred to build a company that could do that for everyone-freeing people from busywork so they could focus on meaningful work. Today, ServiceNow is the AI control tower for business reinvention. Our ServiceNow AI platform brings together any AI, any data, and any workflow- helping 85% of the Fortune 500® work smarter, faster, and better. We're building an AI-native culture where technology and talent are unstoppable together. And we're just getting started.\nJoin us to put AI to work for people.\nWe are the AI Experience Framework (AIUX) team that builds the platform that powers ServiceNow's AI-first user interfaces. Using modern Lit-based web components, AIUX builds modular, reusable conversational experiences that serve as the technical foundation for conversation-first applications like Employee Slate. This role owns full-stack architectural decisions in a modern JavaScript/component-driven environment, working across AI integration, performance scale, and multi-team coordination - spanning our SSR runtime (server-rendered Lit components, versioned request routing, isolated execution pools) and the ServiceNow Glide platform layer it integrates with.\nWhat you get to do in this role: \nOwn code from design, implementation, test automation, and delivery of high-quality product to our users \nWork with product owners to understand detailed requirements and drive the full development lifecycle \nBuild software that is simple to use, allowing customers to extend and customize functionality to meet their specific needs \nContribute to the design and implementation of new products and features while enhancing the existing product suite \nMentor colleagues and promote knowledge-sharing across teams \nApply advanced knowledge of data structures, algorithms, OO design, design patterns, and performance/scale considerations \nRaise the engineering bar through architecture reviews, code reviews, mentoring, and technical direction \nArchitect modular, reusable component systems for scalability and extensibility \nOwn architecture across the request path - proxy, version-aware routing, server-rendered component runtime, and the ServiceNow platform services it calls into \nSet technical direction for framework-level APIs (context propagation, layout composition, state management) consumed by every downstream component team \nRepresent AIUX Framework in cross-org architecture decisions and act as an escalation point for the hardest production issues\nTo be successful in this role you have:\nExperience in leveraging or critically thinking about how to integrate AI into work processes, decision-making, or problem-solving. This may include using AI-powered tools, automating workflows, analyzing AI-driven insights, or exploring AI's potential impact on the function or industry.\n10+ years of professional software engineering experience, with deep expertise in JavaScript and substantial experience in Java or a similar OO language (C++, C#, Go acceptable) \nPassion for JavaScript and the Web as a platform, reusability, and componentization \nAdvanced experience with modern UI frameworks: Angular, React, Vue, or Lit \nAdvanced knowledge of data structures, algorithms, object-oriented design, design patterns, and performance/scale considerations \nAdvanced knowledge and experience with relational databases: development, troubleshooting, and performance optimization \nDeep expertise in server-side rendering and hydration, including the failure modes specific to isomorphic rendering (markup mismatches, browser-API leakage into server code) \nStrong systems-level Node.js experience: process/worker isolation (V8 isolates or equivalent sandboxing), HTTP/1.1 and HTTP/2 semantics, reverse proxying, and designing for concurrent versioned rollouts \nComfortable working across a JVM/Maven backend (Java, ServiceNow Glide platform conventions) in addition to a Node/TypeScript SSR stack \nDemonstrated experience as a technical lead, Staff Engineer, or equivalent senior individual contributor responsible for architecture, technical direction, code quality, and mentoring \nTrack record designing framework-level abstractions (component base classes, context/DI systems, event contracts) consumed by many other engineering teams \nAbility to make pragmatic architecture decisions across performance, reliability, security, maintainability, and delivery speed \nDemonstrated capability to manage multiple projects with material technical risk across teams and processes \nTrack record serving as functional lead or technical owner \nExposure to multiple technology stacks: Cloud Dev, Platforms, Web Dev, Frameworks, service-oriented architecture \nExperience designing and architecting modular, reusable component systems \nPreferred - AIUX Framework specific\nExperience with build systems that emit multiple targets from one component source (server bundles vs. code-split browser bundles) \nHands-on experience operating services in Kubernetes: deployment configuration, scaling, rollout/rollback, and incident response \nExperience building and maintaining observability tooling (Grafana dashboards, Prometheus alerting) for production systems \nFD21\nFor positions in this location, we offer a base pay of $190,900 - $334,100, plus equity (when applicable), variable/incentive compensation and benefits.
