Description

We are seeking a Senior Security Operations Engineer with a strong infrastructure and operations background and expertise across the Microsoft security ecosystem. Candidates with infrastructure or operations experience looking to move laterally into security are encouraged to apply. This is a hands-on senior role within the security operations function, responsible for the design, operation, and continuous improvement of security controls across Microsoft 365, Azure security tooling, AWS environments, enterprise email platforms, and SIEM capabilities. The role also contributes to incident response and security monitoring alongside the wider security team and provides clear visibility of security posture to both technical and senior stakeholders. What will you be doing Work with the Head of Information Security to design, implement, and manage security solutions across Microsoft 365, Azure, and AWS environments. Administer and continuously improve identity and endpoint security across Entra ID, Conditional Access, Intune, and the Microsoft Defender suite. Administer and continuously improve email security platforms, including anti-phishing, anti-spoofing, authentication (DKIM/DMARC/SPF), and email DLP. Maintain and expand SIEM tooling, and conduct regular security assessments across the Microsoft 365, AWS, and email environments to identify vulnerabilities and recommend mitigations. Triage, investigate, and respond to security incidents in line with the incident management standard — working with the external SOC team to monitor and escalate alerts, and producing reports with recommendations and remedial actions. Mentor and guide junior security staff. Create, maintain, and enforce information security policies across Microsoft 365, AWS, email security, and SIEM technologies. Skills and Experience Bachelor's degree in Computer Science, Information Technology or related field (master's preferred); relevant Microsoft and AWS operational experience will be considered in lieu of formal qualifications for the right candidate. A minimum of 7 years' experience with at least 3 at a senior level, focusing on Microsoft and AWS operations, with a passion for all things security. Ability to triage security incidents — assessing severity, scope, and impact, and driving timely escalation and response. Strong operational knowledge of the Microsoft identity and endpoint security stack: Entra ID (including hybrid identity and PIM), Conditional Access, Intune MDM/MAM, the Defender suite (Endpoint, Identity, Cloud Apps), and Microsoft Sentinel/SEIM. Experience with Microsoft Purview, including data classification, sensitivity labels, DLP, insider risk management, and compliance portal administration. Exposure to AWS security services (GuardDuty, Security Hub, IAM, CloudTrail). Demonstrable expertise in enterprise email security platforms, e.g. Mimecast, Proofpoint, and Microsoft Defender for Office 365. A grounding in network security fundamentals — segmentation, zero-trust principles, firewalls, and IDS/IPS. Strong automation skills, particularly for administering and integrating Microsoft security tooling. Excellent communication skills, both written and verbal.
