Infrastructure & Platform Architect L3

Role Summary

Lead the senior onshore architecture view for the ServiceNow CSDM-aligned re-platforming program, owning high-impact design decisions across CMDB, ITOM, integrations, and service operations architecture.

• Represent the technical target state in stakeholder-facing discussions, ensuring that CSDM, CMDB integrity, Service Mapping, Discovery, Event Management, and platform governance remain coherent end to end.
• Provide stronger architecture authority than the L2 profile, including design governance input, senior stakeholder interaction, and guidance on acceptable deviation from OOTB platform behaviour.
• Ensure the solution is architected to support reliable ITSM, ITOM, service model, reporting, and future AI/AIOps readiness outcomes as described in the SoW.
• Operate at high level with emphasis on strategic architecture leadership, onshore-facing representation, and preservation of long-term platform sustainability.

Key Responsibilities

• Own the review and validation of CSDM target architecture, service taxonomy, CI model design, and integration architecture decisions that shape the overall transformation outcome.
• Lead architecture walkthroughs with delivery leadership and customer-side stakeholders, explaining design rationale, delivery implications, and required standards compliance.
• Guide sequencing of foundational capabilities such as environment setup, CMDB baseline, Discovery, core integrations, and Service Mapping progression in line with the path-critical delivery model.
• Oversee governance of exceptions, OOTB restoration decisions, architecture risk items, and design quality gates that influence downstream build, testing, and cutover stages.
• Advise on readiness for SIT, UAT, production cutover, operational runbooks, and BAU transition from the perspective of architecture completeness and resilience.
