ServiceNow is seeking a Senior Software Engineer to own the server-side JavaScript engine at the heart of the ServiceNow platform. You will develop and maintain the runtime that powers custom applications, workflows, and business logic, ensuring apps move smoothly and securely from development to production.
In this role, you will:
- Own code from design, implementation, test automation, and delivery across the scripting engine and broader platform surfaces
- Work with platform teams and internal stakeholders to understand requirements and drive the full development lifecycle
- Build software that is simple to use, allowing customers to extend and customize functionality
- Contribute to the design and implementation of new capabilities while maintaining and enhancing existing functionality
- Mentor colleagues and promote knowledge-sharing across teams
- Apply advanced knowledge of data structures, algorithms, object-oriented design, design patterns, and performance/scale considerations
- Architect modular, reusable systems for scalability and extensibility
This role requires deep expertise in compiler and runtime systems. You will optimize execution engines, memory management, and performance at the systems level.
REQUIREMENTS:
- Experience in leveraging or critically thinking about how to integrate AI into work processes, decision-making, or problem-solving (may include using AI-powered tools, automating workflows, analyzing AI-driven insights, or exploring AI's potential impact on the industry)
- 3+ years of experience with Java or similar object-oriented language (C++, C#, Go equivalent acceptable)
- Passion for JavaScript as a language — its semantics, execution model, and evolution — as well as the Web as a platform
- Experience with backend or systems-level programming; exposure to language internals (parsing, compilation, interpretation) is a plus but not required
- Advanced knowledge of data structures, algorithms, object-oriented design, design patterns, and performance/scale considerations
- Familiarity with distributed systems concepts — resource isolation, concurrency, and scaling execution across shared infrastructure
- 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 (JVM/backend systems, platform infrastructure, security and sandboxing, service-oriented architecture) is a strong plus
