Senior ServiceNow Developer  - AI and Digital Innovation

Role Purpose:

The ServiceNow AI / Agent Engineer is responsible for building AI-enabled agent  capabilities that automate analysis, verification, document generation, and review, and integrating them cleanly into ServiceNow workflows. 

This role focuses on agent design, tool/subflow creation, evaluation, regression, and quality, rather than generic data science or model research. 

 

 

       Key Responsibilities :

AI Agent Build & Integration 

• Build AI agents (or agent-like services) that perform:   

o    rule codification 

o    anomaly detection and analysis 

o    verification and reconciliation 

o    document generation 

o    document review and issue highlighting 

• Implement agents as callable tools/components that can be invoked from

ServiceNow Integration 

• Integrate agents into ServiceNow using:   

o    Flow Designer subflows 
o    REST integrations 

o    structured payloads 

• Write outputs back to ServiceNow case records and evidence stores. 
• Work closely with Workflow Engineers to define invocation points and error 

handling. 

Evaluation, Regression & Hardening:

• Design and maintain agent evaluation packs:  

o    representative test inputs 
o    expected outcomes 

• Execute regression testing during hardening sprints to ensure:   

o    consistency 

o    no quality degradation across releases 

• Tune prompts/tools and logic based on SME feedback and test outcomes. 
  Quality, Controls & Compliance 
• Ensure agents operate within defined guardrails:   

o    no uncontrolled side effects 

o    explainable outputs where required 

• Support control-heavy use cases (e.g., reconciliation, review packs). 
• Assist in producing evidence required for audit, validation, and regulatory review.

 

 

       Required Technical Skills (Must Have) :

• Experience building AI-enabled functionality that integrates into enterprise

workflows. 

• Strong understanding of:  

o    API-based service integration 
o    structured inputs/outputs 

o    error handling and retries 

• Hands-on experience with:  

o    Python / similar backend language 

o    prompt or rule-based logic 

o    evaluation and test harness design. 

 

 

       

Required ServiceNow Knowledge: 

• Familiarity with:  
• ServiceNow Flow Designer integration patterns
•  Subflows and callable actions
• ServiceNow data structures for writing/reading outputs 

• Experience integrating external services into ServiceNow (preferred, not

necessarily certified). 

 

Desirable / Nice-to-Have Skills:

• Experience with agentic AI patterns (tool-calling, structured workflows, 

evaluation). 

• Exposure to enterprise document generation/review use cases. 
• Familiarity with Snowflake-based data consumption (reading curated data

marts). 

• Experience working in regulated industries (Finance, Tax, Risk, Compliance).

 

 

       Experience & Profile:

• 3+ years software/AI engineering experience. 
• Comfortable working in a delivery-focused AI implementation (not pure 

research). 

• Strong collaboration skills with workflow engineers and SMEs. 
• Quality-driven mindset with comfort in gated releases and regression cycles.
