Role Summary

We are looking for an experienced, hands-on Infrastructure Engineer to join TBI's Digital & Technology team for a critical period of infrastructure and cyber security delivery. This is not a purely advisory security role. We are looking for someone who is comfortable getting into the technology, identifying what needs to change and implementing those changes. A major priority will be helping TBI successfully deliver its next Cyber Essentials / Cyber Essentials Plus certification. We therefore particularly want to hear from engineers who have taken an organisation through the certification process before and understand how to translate security requirements into practical technical remediation. Alongside this, you will provide senior 3rd-line infrastructure expertise across our Microsoft 365 and cloud environment and work closely with our Technical Architect, infrastructure and support teams, and managed Security Operations Centre (SOC).

Key Responsibilities

• Infrastructure & Platform Management: Maintain and support the 3rd line infrastructure estate, managing the Azure platform (PaaS, IaaS, VNETs and storage accounts) and the wider M365 estate, including Exchange Online, Teams (incl. telephony integration), OneDrive and SharePoint Online.
• Security Operations: Act as the primary internal liaison with the managed third-party SOC, monitoring and responding to security alerts using Microsoft Defender XDR and Microsoft Sentinel, and supporting incident triage, containment and root cause analysis.
• Vulnerability & Patch Management: Conduct regular vulnerability assessments, track remediation progress and support patch management across the estate.
• Compliance & Certification: Support Cyber Essentials (and Cyber Essentials Plus) certification activities, implementing and recommending remediations to close identified gaps, and assist with internal and external audits and security assessments.
• Collaboration: Work closely with the Technical Architect to design and implement secure, scalable infrastructure solutions, and with the IT Service Desk and wider Infrastructure team to ensure secure configurations and timely resolution of issues.
• Data Protection & Email Security: Assist with the management and configuration of email protection, web control, data loss prevention (DLP), and device monitoring platforms.
• Threat Intelligence & Policy: Contribute to threat intelligence analysis and recommend defensive improvements; support the development and maintenance of security policies, procedures and technical standards.
• Automation & Documentation: Develop and maintain PowerShell scripts to automate routine administrative and security tasks, and produce and maintain accurate system documentation.
• Backup & Resilience: Manage and test M365 and Azure backup and disaster recovery arrangements.
