Office location with Hybrid working: Hammersmith

About the role and the Team:

The Enterprise Architect – ServiceNow is a senior individual contributor within the Enterprise Architecture function, accountable for the architecture, governance and roadmap of the ServiceNow platform as a strategic workflow and service management capability across the company. The role owns the platform target architecture and standards, spanning core modules such as CMDB/CSDM, IT Service Management (ITSM), Customer Service Management (CSM), Field Service Management (FSM) and IT Operations Management(ITOM), ensuring the platform is coherent, scalable, well-governed and aligned with the enterprise architecture and customer-centric transformation goals.

The architect defines how ServiceNow integrates with the wider OSS/BSS and enterprise landscape, establishes configuration-over-customisation principles, instance and upgrade strategy, and data/CMDB governance, and champions the adoption of platform AI capabilities (e.g. Now Assist, predictive intelligence and intelligent automation). Designs are presented through the Architecture Review Board and Design Review Board, working in close partnership with Service Operations, Customer Experience, Field Operations, Networks and deliveryfunctions, as well as the ServiceNow vendor and implementation partners.

Success requires outstanding communication and stakeholder management: the architect must be able to simplify complex platform scenarios for executive, business and technical audiences, and to guide solutions through the full project delivery lifecycle to successful outcomes.

What will you be doing?

• Define architecture and standards across core modules including CMDB/CSDM, ITSM, CSM, FSM and ITOM (Discovery, Event Management, Service Mapping), and assess the fit of additional capabilities (e.g. Telecommunications Service Management, ITAM, HRSD, App Engine) against business demand.

• Work with the Data function to align ServiceNow data architecture with the wider enterprise data strategy, reporting and analytics.

Integration & Solution Design Oversight

• Provide architectural leadership on strategic programmes with ServiceNow scope, taking an end-to-end view across business processes, platform capabilities and integrations through the full project delivery lifecycle.
• Produce and review high-level and solution designs, presenting them through the Architecture Review Board (ARB) and Design Review Board (DRB) with clear rationale, options analysis and traceability.
• Actively resolve complex platform, data and integration issues, providing clear direction and pragmatic solutions that keep delivery moving.

• Present complex platform scenarios in a clear, simple and compelling way to audiences ranging from developers to senior leadership.
• Support the management of the ServiceNow vendor relationship and implementation partners, contributing to licensing, roadmap and capability discussions to ensure value for money.

Governance, Standards & Capability Development

• Set standards, patterns and ways of working for ServiceNow design and development, coaching developers, designers and analysts to raise capability across the function.
• Maintain awareness of the ServiceNow release roadmap and industry best practice, translating it into pragmatic improvements to the platform roadmap.
