For the further development of a complex ServiceNow platform, a developer specializing in the middlelayer level is sought. The focus is on implementing business logic, integrations, and data processing between the frontend and backend systems.
Typical Areas of Responsibility:
Design and development of server-side business logic in ServiceNow using Business Rules, Script Includes, and Workflows.
Design, implementation, and maintenance of REST- and SOAP-based integrations to third-party systems (e.g. SAP, Jira, HR systems) via IntegrationHub or custom scripts.
Development and optimization of data flows and transformations within the platform.
Performance analysis and optimization of server-side scripts and database interactions.
Ensuring platform stability and security through robust and error-resistant coding.
Relevant Technologies, Tools or Methods:
ServiceNow platform: in-depth knowledge of the Glide API (GlideRecord, GlideSystem), server-side scripting (JavaScript ES5).
Integrations: IntegrationHub (Spokes), REST/SOAP API Explorer, JSON, XML.
Automation: Flow Designer, Workflow Editor.
Development tools: ServiceNow Studio, VS Code with ServiceNow plugins.
Methodology: Agile (Scrum), use of Update Sets and Application Scopes for deployment.
Typical KPIs or Success Metrics:
Transaction response times for critical middlelayer processes.
Error rate for API calls and integrations (< 1%).
Success rate of automated workflows.
Code complexity (e.g., measured via SonarQube integration).
Adoption rate of new functionalities enabled by the middlelayer.
Particular Challenges, Risks or Specifics:
Complexity of dependencies between various ServiceNow modules and external systems.
Ensuring scalability with high transaction volumes.
Debugging asynchronous processes and integrations.
Adhering to ServiceNow best practices to avoid compromising platform upgradeability ("out-of-the-box" vs. customizing).
Concrete Deliverables:
Implemented and tested Script Includes and Business Rules.
Fully configured and documented integrations in IntegrationHub.
Technical documentation of the developed logic and data flows.
Completed Update Sets, ready for deployment to the production environment.
Lessons Learned / Best Practices:
Reusable logic should be encapsulated in Script Includes rather than duplicated across multiple Business Rules.
Asynchronous Business Rules should be preferred for long-running operations to avoid blocking the user experience.
The Flow Designer is preferable to the classic Workflow Editor for new automations.
