Senior Microsoft 365 Consultant (Contract)

• Deliver across several parallel workstreams on an ongoing Microsoft programme for a large enterprise customer
• Configure Microsoft 365 across the core workloads and deliver tenant hardening
• Implement and tune Defender and the wider Microsoft 365 security stack
• Deliver the identity side of a wider business system change, covering Entra, access and authentication
• Run application and tenant migrations across the Microsoft estate, including moving Power Platform apps where they are in scope
• Hold the technical relationship with a demanding customer, managing expectations and pushing back where a request needs challenging

• A seasoned technical consultant, used to high stakes enterprise accounts and the scrutiny that comes with them
• Broad Microsoft 365 consulting background, strong across general configuration rather than deep in one workload
• Hands on with Defender and the Microsoft 365 security stack, including tenant hardening
• Entra and identity delivery, including supporting wider application or infrastructure programmes
• Experience of application and tenant migrations
• Partner, consultancy or managed service provider background, delivering into large or complex environments
• Confident with difficult stakeholder conversations and working without close supervision
• Available at short notice for an initial six month engagement

Desirable

• Power Platform exposure, particularly moving apps between tenants. A CRM background is a bonus but not expected
• Fundamental networking understanding, enough to sit alongside a SASE rollout integrated with Azure

This contract sits with an established cloud and managed services provider running an ongoing programme of Microsoft work for one of its larger enterprise customers. It is a deliberately generalist brief. Several workstreams run at once, so they want someone who can pick up a piece of work, deliver it properly and move on to the next, rather than a specialist in a single product.

Live workstreams span Microsoft 365 configuration and tenant hardening, Defender and the wider security stack, application and tenant migrations, and the identity side of a business system change being run elsewhere. Power Platform comes into it as part of the migration work, moving apps across rather than building new ones from scratch. A SASE network rollout integrated with Azure sits alongside it all.

Worth being straight about the environment. This is a demanding enterprise customer working at pace, where the stakes on each change are high. It needs a seasoned consultant who has handled that kind of account before, can hold their own with a challenging stakeholder, and keeps delivery moving without being managed.

Why This Role Stands Out

• Genuine variety. Security, identity and migration work inside one engagement, which is rare on a contract this length
• Six months initially, on a programme with more work behind it rather than a short fixed piece of delivery
• Real ownership. You take a workstream from design through to implementation
• The provider runs its own managed services, so the work has to stand up operationally, not just pass a design review
