Job Title: Senior Engineer - CMDB OT & Discovery
GCL:D1/D2/D3
Introduction to role:
Are you ready to build a trusted view of Operational Technology that keeps manufacturing running and safeguards patient supply? Step into a visible, hands-on role where you connect discovery data, govern configuration quality and model IT-to-OT dependencies to strengthen operational resilience across our plants. Do you enjoy turning complex discovery signals into clean, decision-ready configuration models that leaders can rely on during incidents and change?
You will serve as the subject-matter guide for OT configuration data in ServiceNow. You will integrate authoritative sources like Claroty xDome. You will be responsible for crafting CI classifications and relationships. You will link assets to accountable owners, applications, and services. Working in a globally distributed team across the UK and our technology hub in Chennai, you will partner with OT cybersecurity, manufacturing application owners, site engineering, quality, enterprise architecture and network teams to ensure configuration data is accurate, auditable and actionable.
Accountabilities:
OT Asset Lifecycle and Discovery: Maintain an accurate, reconciled inventory of in-scope OT assets in ServiceNow with owners, support groups, locations and lifecycle status aligned to authoritative sources. Define and enforce OT CI classifications, required attributes, relationships and onboarding standards. Drive discovery coverage across sites and zones using passive approaches and trusted OT platforms, avoiding unnecessary active scanning and respecting production constraints. Govern onboarding through retirement, validate stale or absent assets with owners and prevent reappearance of retired CIs while retaining required history.
Claroty Integration and Reconciliation: Act as the CMDB specialist for Claroty xDome data. Maintain device-type, class and attribute mappings; monitor end-to-end data flow from discovery source through the engine handling recognition and matching to CI creation and updates. Investigate failed jobs, mapping errors, duplicates and source-to-target discrepancies; coordinate fixes and validate outcomes. Set source precedence to protect authoritative OT data and retain full traceability; collaborate with CMDB/integration engineering on complex IRE changes.
IT-to-OT Dependency Modeling and Manufacturing Alignment: Build and maintain dependencies linking manufacturing services and applications, including PAS-X and TrakSYS, to OT systems, servers, databases, middleware, interfaces, networks, gateways, cloud/platform services and OT devices. Validate critical dependencies with application owners and OT engineers, identify and remediate gaps or orphaned assets and periodically certify high-impact relationships to enable reliable impact analysis.
Data Quality and Governance: Own OT-specific data quality analysis for completeness, correctness, compliance, freshness and relationship coverage. Establish preventative controls, coordinate remediation with source owners and track exceptions and risks. Maintain documentation for sources, mappings, modeling decisions and controls, and provide configuration evidence for audit and regulatory requests.
Collaborator Collaboration and Enablement: Translate OT needs into actionable CMDB requirements and working standards. Partner across cybersecurity, application ownership, network, infrastructure, cloud and asset management to align discovery, identification and reconciliation practices. Guide collaborators on CMDB guidelines to improve operational resilience and manufacturing impact analysis.
Essential Skills/Experience:
Bachelor’s degree in Engineering, Computer Science or Information Technology, or equivalent experience.
6–9 years of experience in asset management, configuration management, CMDB, discovery or cyber visibility roles, including at least 3 years in OT or industrial environments.
