If you've spent years navigating the gap between legacy SharePoint environments and where the platform needs to be — and you actually enjoy solving that problem — this role is worth a look.

One of the world's leading law firms are looking for a Senior SharePoint Developer & Administrator to own the modernisation of their SharePoint estate — migrating from SharePoint 2016 on-prem, rewriting legacy web parts, and building out a modern intranet on SharePoint Online. This isn't a ticket-taking role. You'll have real scope, technical depth, and stakeholder exposure.

What you'll be doing
  • Leading migration from SharePoint 2016 on-prem to SharePoint SE and SharePoint Online
  • Rebuilding legacy web parts using SPFx (Type Script, React, REST APIs, Microsoft Graph)
  • Administering both on-prem and cloud environments — patching, upgrades, governance, DR
  • Configuring Business Connectivity Services and External Content Types
  • Designing and maintaining the enterprise intranet — architecture, navigation, branding
  • Providing technical leadership to junior developers and shaping platform standards
What we're looking for
  • Strong hands‑on experience with SharePoint SE and SharePoint Online
  • Experience with C# / .NET, SQL Server, and RESTful API integrations
  • Solid on‑prem admin background — patching, performance tuning, troubleshooting
  • BCS and ECT experience a strong plus
  • Microsoft 365 / Azure familiarity (Azure AD, Azure Functions) is a bonus
Why it's worth considering
  • Rare opportunity to own a full‑scale SharePoint modernisation at a global law firm
  • Broad technical scope — development, administration, integration, and intranet design
  • Exposure to senior stakeholders and real influence over platform direction
  • A firm that takes its technology estate seriously
