For the further development of a complex ServiceNow platform, a developer specialized in the middle layer is sought. The focus is on implementing business logic, integrations, and processing data between the frontend and backend systems.
Typical responsibilities:
Designing and developing 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.
Analyzing performance and optimizing server-side scripts and database interactions.
Ensuring platform stability and security through robust, 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 for API calls and integrations (< 1%).
Success rate of automated workflows.
Code complexity (e.g., measured via SonarQube integration).
Adoption rate of new features enabled by the middle layer.
Key challenges, risks, or specifics:
Complexity of dependencies between different ServiceNow modules and external systems.
Ensuring scalability under high transaction volumes.
Debugging asynchronous processes and integrations.
Adhering to ServiceNow best practices to keep the platform upgradeable ("out-of-the-box" vs. customizing).
Specific 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 production.
Lessons learned/best practices:
Encapsulate reusable logic in script includes instead of duplicating it across multiple business rules.
Prefer asynchronous business rules for long-running operations to avoid blocking the user experience.
Use Flow Designer over the classic Workflow Editor for new automations.
