Senior SharePoint Engineer

PGI's Senior SharePoint Engineer will play a crucial role in ensuring the stability, security, and scalability of our IT infrastructure. This position combines technical expertise with hands-on implementation, proactive system management, and a commitment to continuous improvement. You will work closely with the IT team and business stakeholders to deliver robust infrastructure solutions that align with organisational goals.

What you’ll be doing:

• Design, deploy, and manage scalable, secure Microsoft 365 information management solutions, using SharePoint Online, Teams, OneDrive, Entra ID, Purview, Power Platform/Logic Apps, and related Microsoft technologies where appropriate.
• Lead the design and implementation of a modern SharePoint information architecture, including sites, hub sites, document libraries, storage strategy, content types, managed metadata, term store structures, column design, and folder-versus-metadata models.
• Plan and deliver end-to-end migrations from on-premises Windows file servers to SharePoint Online, including analysis, restructuring, storage model design, and reduction of uncontrolled file sprawl or ad hoc sharing.
• Redesign and standardise permissions and access models, replacing legacy file-share ACLs with role-based access controls using Entra ID groups, SharePoint and Teams governance, least-privilege principles, and internal/external sharing controls.
• Implement and manage Microsoft Purview and SharePoint security and compliance capabilities, including sensitivity labels, default encryption, DLP, data lifecycle and retention policies, DSPM, access governance, audit/reporting, and insider risk management.
• Define and roll out organisation-wide data storage standards, including when to use SharePoint, Teams, and OneDrive; naming conventions; taxonomy; lifecycle management; and document management governance.
• Design and deploy Teams and SharePoint templates to improve consistency across departments and projects.
• Use SharePoint Syntex, Power Platform, Logic Apps, scripting, and automation to improve document classification, extraction, process efficiency, and infrastructure management.
• Configure and optimise search and metadata-driven discovery, including managed properties, refiners, search schema, and metadata optimisation.
• Maintain clear technical documentation, standards, procedures, and reporting data for information management performance, risks, issues, and improvements.
• Provide ongoing administration, optimisation, troubleshooting, escalation support, backup/disaster recovery input, and continuous improvement for SharePoint, Teams file storage, and Microsoft 365 document management services.
• Work closely with IT colleagues, business stakeholders, and external vendors to understand requirements, provide expert guidance, communicate progress, challenge decisions where needed, and deliver well-documented solutions with minimal supervision.
• Deliver training, adoption support, change management, and knowledge sharing so staff and IT colleagues understand how to store, secure, find, and manage information effectively.
• Contribute expert input to security policies and ensure information management solutions support relevant requirements including Cyber Essentials+, ISO/IEC 27001, and UK GDPR.
