Senior Staff Applications Development Engineer

We 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.

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

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

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
