For the further development of a complex ServiceNow platform, a developer specializing in the middle layer is sought. The focus is on implementing business logic, integrations, and processing data between the frontend and backend systems.
Typical areas of activity:
Design and development of server-side business logic in ServiceNow using Business Rules, Script Includes, and Workflows.
Designing, implementing, and maintaining REST- and SOAP-based integrations with third-party systems (e.g., SAP, Jira, HR systems) via IntegrationHub or custom scripts.
Developing and optimizing 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 middle-layer processes.
Error rate in 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 middle layer.
Specific 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 jeopardizing platform upgradability ("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 developed logic and data flows.
Completed Update Sets, ready for deployment to the production environment.
Lessons learned/best practices:
Encapsulate reusable logic in Script Includes instead of duplicating it in multiple Business Rules.
Prefer asynchronous Business Rules for long-running operations to avoid blocking the user experience.
The Flow Designer is preferred over the classic Workflow Editor for new automations.
