Senior Principal - P&C Platform Engineer

About the role

This is the hands-on build role. The Platform Engineer takes architecture direction and a prioritised backlog and turns them into working, tested, automated, documented configuration in production. The expectation is engineering rather than administration: configuration expressed as code and deployed through pipelines, not clicked through a portal and remembered by whoever was on shift.

What you'll do

• Design, build, test and deploy configuration across the Microsoft 365 estate: Teams policies, SharePoint and OneDrive settings, Exchange Online transport and mail flow
• Implement to the reference architecture and standards set by the Principal Architect
• Deliver backlog items from sprint to production with the tests, telemetry, documentation and rollback path included — "done" means running and observable
• Build and maintain integrations using Microsoft Graph and platform APIs; write the connective tissue between M365, ServiceNow, HR systems and the wider application estate
• Automate everything that would otherwise be done twice. Provisioning, lifecycle, reporting, remediation, joiner/mover/leaver flows, licence assignment and reclamation
