• Bachelor's degree in Computer Science, Software Engineering, Information Systems, or a related technical field. Relevant additional experience may be considered in place of a degree.
• Seven or more years of software development experience, including at least four years of hands-on ServiceNow application development.
• Demonstrated experience designing and developing complex custom or scoped applications.
• Advanced JavaScript skills and strong software engineering and object-oriented design fundamentals.
• Advanced experience with Business Rules, Script Includes, Client Scripts, UI Policies, ACLs, Glide APIs, Flow Designer, scheduled processing, and REST integrations.
• Experience designing integrations with external enterprise systems, including authentication, transformation, error handling, retries, and transaction logging.
• Experience conducting code reviews, defining development standards, and mentoring developers.
• Strong understanding of data modeling, application security, performance, testing, debugging, and release management.
• Ability to convert requirements into technical designs and estimates and explain complex issues to technical and nontechnical stakeholders.

Preferred Qualifications

• ServiceNow Certified System Administrator and Certified Application Developer; relevant implementation or micro-certifications.
• Experience with App Engine, IntegrationHub, Automated Test Framework, source control integration, and application deployment.
• Hands-on experience integrating ServiceNow with AWS-hosted services.
