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. ### What you get to do in this role - Own code from design, implementation, test automation, and delivery of high-quality product to our users - Work with product owners to understand detailed requirements and drive the full development lifecycle - Build software that is simple to use, allowing customers to extend and customize functionality to meet their specific needs - Contribute to the design and implementation of new products and features while enhancing the existing product suite - Mentor colleagues and promote knowledge-sharing across teams - Apply advanced knowledge of data structures, algorithms, OO design, design patterns, and performance/scale considerations Raise the engineering bar through architecture reviews, code reviews, mentoring, and technical direction Architect modular, reusable component systems for scalability and extensibility - Own architecture across the request path — proxy, version-aware routing, server-rendered component runtime, and the ServiceNow platform services it calls into - Set technical direction for framework-level APIs (context propagation, layout composition, state management) consumed by every downstream component team Represent AIUX Framework in cross-org architecture decisions and act as an escalation point for the hardest production issues ## Qualifications To be successful in this role you have: Experience 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. 10+ 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) Passion for JavaScript and the Web as a platform, reusability, and componentization Advanced experience with modern UI frameworks: Angular, React, Vue, or Lit Advanced knowledge of data structures, algorithms, object-oriented design, design patterns, and performance/scale considerations Advanced knowledge and experience with relational databases: development, troubleshooting, and performance optimization Deep expertise in server-side rendering and hydration, including the failure modes specific to isomorphic rendering (markup mismatches, browser-API leakage into server code) - Strong 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 Comfortable working across a JVM/Maven backend (Java, ServiceNow Glide platform conventions) in addition to a Node/TypeScript SSR stack - Demonstrated experience as a technical lead, Staff Engineer, or equivalent senior individual contributor responsible for architecture, technical direction, code quality, and mentoring - Track record designing framework-level abstractions (component base classes, context/DI systems, event contracts) consumed by many other engineering teams - Ability to make pragmatic architecture decisions across performance, reliability, security, maintainability, and delivery speed - Demonstrated capability to manage multiple projects with material technical risk across teams and processes - Track record serving as functional lead or technical owner Exposure to multiple technology stacks: Cloud Dev, Platforms, Web Dev, Frameworks, service-oriented architecture Experience designing and architecting modular, reusable component systems Preferred — AIUX Framework specific Experience with build systems that emit multiple targets from one component source (server bundles vs. code-split browser bundles) ### Hands-on experience operating services in Kubernetes deployment configuration, scaling, rollout/rollback, and incident response Experience building and maintaining observability tooling (Grafana dashboards, Prometheus alerting) for production systems FD21 For positions in this location, we offer a base pay of $190,900 - $334,100, plus equity (when applicable), variable/incentive compensation and benefits.
