As a Senior Security Engineer in our Digital Workplace Area, you will contribute to the development and structure around SEBs core security capabilities.

Through close collaboration with Security Operations, Microsoft EntraID, cloud platform team, architects and Group Security function, you will enable effective threat protection, detection and response. This is a platform-focused engineering role rather than a SOC analyst role: your contribution is to build, integrate and continuously improve the Microsoft capabilities that strengthen Cyber Security and Zero Trust across SEB.

The role combines senior-level Microsoft 365 platform engineering with hands-on experience of security capabilities in Microsoft Defender. You will drive modernization, operational readiness and long-term service ownership, and translate security requirements into solutions that work across the Digital Workplace, endpoint, identity and Azure environments.

Your work will help ensure that identity, collaboration, information and endpoint-related security controls are scalable, reliable and aligned with the bank's overall security posture.

In this role you will:

• Configure and maintain security policies across Defender suite

• Implement and fine-tune security controls and policies based on requirements, incidents new threats

• Investigate and troubleshoot platform related incidents together with SOC or other teams identifying relevant remediation changes or improvements

• Troubleshoot for example, endpoint protection issues together with device management and Intune teams, for example onboarding problems, sensor health, security configuration, attack surface reduction rules and endpoint exclusions

• Evaluate and implement new Defender capabilities and Microsoft security features

To thrive in this role, we believe you have:

• Senior-level experience designing, engineering and operating Microsoft 365 in a large enterprise environment and related administration and governance capabilities.

• Hands-on experience implementing operating and improving security capabilities within the Microsoft Defender ecosystem, including Microsoft Defender XDR, Defender for Office 365, Defender for Endpoint, Defender for Identity or Defender for Cloud Apps.

• Strong knowledge of Microsoft Entra ID, including authentication, Conditional Access, identity protection, application identities and integration between identity and Microsoft 365 services.

• Experience translating security and architecture requirements into scalable platform configurations, integrations, policies, and operational processes.

• Understanding of Zero Trust, cloud security and secure-by-design principles

• Strong stakeholder management and communication skills, fluent English in speech and writing, and experience supporting or coaching colleagues.

You understand that strengthening security is not only about responding to incidents. It is about building a well-governed, resilient and user-friendly platform where identity, technology, processes and people work together.

You are motivated by taking ownership, collaborating across organizational boundaries and delivering security capabilities that make a measurable contribution to the bank's overall security posture.
