Job description

Senior StaffApplicationsDevelopment Engineer

• Full-time
• Employee Type: Regular
• Region: AMS - North America and Canada
• Work Persona: Flexible

It all started when engineer Fred Luddy wrote code that automated a tedious task for his coworker, Phyllis. 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.

Join us to put AI to work for people.

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

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.
• 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
• 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

• 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
