By 2031, we aim to deliver £40 billion in annual sales, leveraging our existing strong performance momentum to significantly increase our positive impact on the health of billions of patients globally. Our Ahead Together strategy is centred on early intervention to prevent and alter the course of disease, thereby protecting people and supporting healthcare systems.\nOur diverse portfolio consists of vaccines, specialty medicines, and general medicines.\nThrough continuous innovation and a dedicated focus on scientific and technical excellence, we strive to develop and launch new, groundbreaking treatments that address critical health challenges.\nJob Purpose\nBuild, automate and run the platform that 50,000+ employees across [X] countries use to communicate and collaborate - Microsoft Teams, SharePoint Online and OneDrive, Exchange Online, the Microsoft 365 apps, Power Platform and Microsoft 365 Copilot.\nThis 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.\nThe role also runs what it builds. Platform Engineers own the operational health of their workloads - diagnosing the awkward, intermittent, only-happens-in-Tokyo problems that never reproduce in a lab, and eliminating the root cause rather than closing the ticket.\nKey Responsibilities\n\nDesign, build, test and deploy configuration across the Microsoft 365 estate: Teams policies, SharePoint and OneDrive settings, Exchange Online transport and mail flow, Purview policies, Entra ID groups and Conditional Access as it applies to collaboration workloads.\nImplement to the reference architecture and standards set by the Principal Architect; raise a design challenge when reality does not match the design rather than quietly deviating.\nDeliver backlog items from sprint to production with the tests, telemetry, documentation and rollback path included - \"done\" means running and observable, not merely configured.\nBuild and maintain integrations using Microsoft Graph and platform APIs; write the connective tissue between M365, ServiceNow, HR systems and the wider application estate.\nAutomate everything that would otherwise be done twice. Provisioning, lifecycle, reporting, remediation, joiner/mover/leaver flows, licence assignment and reclamation.\nExpress tenant configuration as code in version control; build and maintain CI/CD pipelines for policy and solution deployment with automated validation and staged ring-based rollout.\nReplace manual runbook steps with self-healing and self-service; treat a recurring manual task as a defect with a backlog item attached.\nOwn operational health of assigned workloads: monitoring, alerting, capacity, service health response and performance.\nInvestigate and resolve complex incidents and problems - third-line escalation for collaboration platform issues - and drive permanent root-cause elimination.\nParticipate in an on-call rotation for major incidents affecting the collaboration platform.\nManage the continuous change stream from Microsoft: assess message centre and roadmap items, test in a lab tenant, and implement, defer or disable with the reasoning recorded.\nMaintain patch, currency and configuration compliance; remediate vulnerabilities and drift.\nImplement and maintain security and information governance controls in the collaboration estate: sensitivity labels, DLP, retention, external sharing controls, app consent and Conditional Access.\nProduce the evidence that audits require - configuration baselines, change records, access reviews - generated automatically wherever possible.\nBuild to regulated-environment requirements where applicable, including GxP-validated systems and the qualification and change control they demand.\nWork daily with the Product Owner on refinement and estimation, and with the Architect on design; give honest estimates and flag risk early.\nProduce operational documentation, runbooks and knowledge articles good enough that the service desk can use them and the next engineer can pick the work up.\nSupport and coach the service desk and second-line teams; reduce escalation volume by transferring capability, not by absorbing it.\nMentor junior engineers and contribute to engineering standards and code review within the squad.\nEducation & Professional Qualifications\nBachelor's degree in Computer Science, Engineering or a related discipline, or equivalent demonstrable professional experience. Strong practical experience is an acceptable substitute for formal qualification.\nRelevant certifications desirable (e.g., Microsoft 365 Certified: Administrator Expert, Teams Administrator Associate, Identity and Access Administrator Associate, Information Protection and Compliance Administrator, Power Platform Solution Architect, Azure Administrator, ITIL v4 Foundation).\nArea of Specialisation\nHands-on Microsoft 365 platform engineering across the core collaboration workloads - Exchange Online, SharePoint Online / OneDrive and Microsoft Teams - at 50,000-user scale.\nConfiguration-as-code for tenant settings - Git, CI/CD pipelines, automated validation and staged ring-based rollout - plus advanced PowerShell and Microsoft Graph automation.\nMicrosoft Purview implementation - sensitivity labels, DLP, retention - and the practical behaviour of external sharing, Conditional Access and app consent controls once real users meet them.\nComplex collaboration-platform troubleshooting across client, identity, network and service layers, with root-cause elimination rather than ticket closure.\nExperience Required\n15Years overall and 10+ years in IT engineering or platform operations, including 5+ years working hands-on with Microsoft 365 in a production enterprise environment.\nExperience supporting or engineering a tenant of 5,000+ users; comfortable with the difference between a small tenant and a large one.\nDemonstrable hands-on capability across at least two of Exchange Online, SharePoint Online/OneDrive, or Microsoft Teams - at a level that includes troubleshooting, not only configuration.\nWorking PowerShell proficiency with real examples of automation delivered into production, plus practical experience calling the Microsoft Graph API.\nFamiliarity with Git and pull-request-based working; willingness to work configuration-as-code if not already doing so.\nExperience operating in an ITIL-aligned change and incident process, including production change ownership.\nExperience delivering within a Scrum or Kanban squad, including refinement, estimation and sprint commitment.\nWillingness to participate in an on-call rotation for major incidents.\nFluent English, written and spoken; able to explain a technical issue to a non-technical colleague.\nDesirable:\nExperience in a regulated industry - pharmaceutical, life sciences, biotech, financial services or healthcare - including GxP/CSV/CSA and validated-system change control.\nMigration delivery at scale - on-premises Exchange or SharePoint to cloud, file share to OneDrive/SharePoint, tenant-to-tenant, or third-party platform (Slack, Zoom, Google Workspace, Box) consolidation.\nTeams Phone / voice - Direct Routing, Operator Connect, PSTN migration.\nTeams Rooms and collaboration hardware - deployment, configuration and remote management at estate scale.\nViva suite implementation - Connections, Engage, Learning, Insights.\nPower Platform development - Power Automate flows, Power Apps, Dataverse, Copilot Studio agents.\nA second language beyond PowerShell - Python, C# or Go - and experience building small services or Azure Functions.\nInfrastructure-as-code tooling - Bicep, ARM or Terraform for the Azure resources supporting the platform.\nEndpoint management adjacency - Intune, device compliance and the endpoint's role in Conditional Access.\nSecurity engineering exposure - Defender for Office 365, Defender for Cloud Apps, threat hunting in M365 audit data.\nAccessibility testing and remediation in collaboration tooling.\nSkills/Background\nDeep hands-on configuration and troubleshooting across the core M365 workloads - Exchange Online (mail flow, transport rules, hybrid, anti-spam), SharePoint Online and OneDrive (site and permission models, sharing controls, migration), and Microsoft Teams (policies, lifecycle, meetings, channels).\nEntra ID as it applies to collaboration - groups and dynamic membership, Conditional Access, app registrations and consent, service principals and app-only authentication.\nMicrosoft Purview implementation - sensitivity labels, DLP policies, retention and disposition - and the practical behaviour of each once real users meet it.\nMicrosoft 365 apps deployment and configuration - servicing channels, policy management via the Cloud Policy service, add-in management.\nPower Platform administration - environments, DLP connector policies, solution deployment and ALM.\nMicrosoft 365 Copilot implementation mechanics - licence assignment, permission and oversharing remediation, and grounding behaviour.\nAdvanced PowerShell - modules, error handling, parameterisation, idempotency; scripts written to be maintained by someone else, not just to run once.\nMicrosoft Graph API fluency - REST, delta queries, permission scopes, app-only auth, throttling and retry handling.\nMonitoring and diagnostics - Log Analytics and KQL, M365 usage and audit telemetry, Power BI reporting; instrumenting your own work so problems surface before users report them.\nComplex troubleshooting - methodical isolation of intermittent, multi-layer problems spanning client, identity, network and service.\nITIL-aligned practice - incident, problem and change management executed properly at enterprise scale, including credible change records and rollback plans.\nProduction discipline - testing in a lab tenant first, ring-based release, blast-radius awareness, and the habit of asking \"what does this do to 50,000 people\" before pressing apply.\nClear technical writing - runbooks, knowledge articles and design notes others can actually follow.\nOwnership - sees an item through to working in production and stays with it when it misbehaves afterwards.\nCuriosity and self-direction - reads release notes, tests in a lab, and brings improvement ideas to refinement unprompted.\nCollaboration - works well with product, architecture, security and the service desk; explains technical constraint without condescension.\nUser empathy - remembers that a policy setting is somebody's Monday morning.\n Skills\nAccess Control (AC), Agile Methodology, Cisco Routing, Cross-Functional Teamwork, Data Analysis, Design Thinking, DevOps, Microsoft Dynamics 365 Data Migration Testing, Microsoft Office 365, Operator Interfaces, Prioritization, Product Development Research, Product Roadmapping, Project Management, Return on Investment (ROI), Software Development, Strategy Deployment, User Experience (UX), User Interface (UI) DesignWhy GSK?\nUniting science, technology and talent to get ahead of disease together.\nGSK is a global biopharma company with a purpose to unite science, technology and talent to get ahead of disease together.
