Job description

About the role

The Security Administrator is a hands-on technical role on the Information Security team, responsible for engineering, hardening, and operating security controls across a hybrid environment spanning Microsoft Azure, Microsoft Entra ID, Microsoft 365, and traditional infrastructure. This is not a policy-focused position. The ideal candidate is an accomplished Security Administrator who can walk into an existing complex environment, quickly understand the architecture, andimmediatelycontribute to incident response, identity and access hardening, cloud security engineering, and vulnerability remediation.

Success in this role requires deep, current technicalexpertisein Information Security, Security Operations, Microsoft Ecosystem, aDevSecOpsmindset, and fluency with automation and infrastructure-as-code / security-as-code practices. The organizationoperatesin a highly regulated financial services environment, so the candidate must apply strong engineering discipline while meeting compliance obligations.

What you’ll do

Security Operations & Incident Response

• Operate, tune, and build detections inMicrosoft Sentinel(KQL foranalytics rules, hunting queries, workbooks) andMicrosoft Defender XDRto detect, investigate, and respond to threats.

• Design and automate response withSOAR playbooks(Logic Apps / Sentinel automation rules) to reduce mean time to respond.

• Lead and coordinate hands-on incidentresponsefor events such as data breaches, malware outbreaks, and identitycompromises, including containment, eradication, and root-cause analysis across cloud and on-premises systems.

• Partner with Security and Risk leadership to translate policies and frameworks into enforceable, technically implemented controls.

• Develop, test, andvalidatedisaster recovery and resilience strategies from a security perspective.

Access Management & Compliance
