Original job description

Archived listing. The details below describe a past opening.

Company Description 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.

Job Description

We are the platform engineers handling app lifecycle at ServiceNow. We develop and maintain the server-side JavaScript engine at the heart of the ServiceNow platform - the runtime that powers custom applications, workflows, and business logic. We ensure apps move smoothly and securely from development to production. This role requires deep expertise in compiler and runtime systems - you'll optimize execution engines, memory management, and performance at the systems level.

What you get to do in this role:

Design and optimize execution engines, JIT/AOT compilation pipelines, and memory management systems to ensure customer applications run at scale
Build high-quality, clean, scalable, and reusable code by enforcing best practices around software engineering architecture and processes (Code Reviews, Unit testing, etc.)
Work with product owners to understand detailed requirements and own your code from design, implementation, test automation, and delivery of high-quality product to our users
Implement software that is simple to use, allowing customers to extend and customize functionality to meet their specific needs
Mentor colleagues and promote knowledge-sharing across teams on low-level systems engineering, performance profiling, and optimization techniques

Qualifications

To be successful in this role you have:

12+ years of experience with Java or similar object-oriented language, with at least 5+ years working on compiler, runtime, JIT/AOT systems, or language execution engines
Experience integrating AI into software development, workflows, decision-making, or automation using AI-powered tools and technologies.
Strong experience with compiler/runtime systems: execution engines, memory management, concurrency, JIT/AOT compilation, performance optimization, profiling, and debugging
Advanced knowledge of data structures, algorithms, object-oriented design, design patterns, and performance/scale considerations at the systems level
Passion for JavaScript and the Web as a platform; experience with modern UI frameworks (Angular, React, or Vue)
Experience developing, troubleshooting, and optimizing relational databases
Experience with LLVM, language runtime development, or low-level systems engineering (strong plus)
Track record working across multiple technology stacks (Cloud Dev, Platforms, Web Dev, Frameworks, service-oriented architecture)
Capability to manage multiple projects with material technical risk across teams and processes; may serve as functional lead or technical owner

For positions in this location, we offer a base pay of $171,900 - $300,800, plus equity (when applicable), variable/incentive compensation and benefits. Sales positions generally offer a competitive On Target Earnings (OTE) incentive compensation structure. Please note that the base pay shown is a guideline, and individual total compensation will vary based on factors such as qualifications, skill level, competencies, and work location. We also offer health plans, including flexible spending accounts, a 401(k) Plan with company match, ESPP, matching donations, a flexible time away plan and family leave programs. Compensation is based on the geographic location in which the role is located and is subject to change based on work location.

Work personas (flexible, remote, or required in office) are categories that are assigned to ServiceNow employees depending on the nature of their work and their assigned work location. Learn more here. To determine eligibility for a work persona, ServiceNow may confirm the distance between your primary residence and the closest ServiceNow office using a third-party service.
