Responsibilities
Microsoft Purview Administration (Compliance & Data Governance)
- Configure and manage Purview capabilities to support compliance objectives, including data classification and labeling, data loss prevention (DLP), retention and deletion policies, eDiscovery workflows, and compliance reporting.
- Develop and maintain Purview‑derived compliance artifacts and evidence outputs to support assessments, audits, due diligence, and continuous monitoring aligned to CMMC 2.0 Level 2 and NIST SP 800‑171.
- Define and operate data retention and deletion procedures, integrating with Purview retention controls where appropriate
Microsoft Defender Administration (Threat Protection & Security Operations)
- Configure, tune, and operate Microsoft Defender security controls across identity, endpoints, email/collaboration, and cloud applications, consistent with licensing and compliance scope.
- Monitor alerts, investigate suspicious activity, and drive remediation actions; reducing noise through continuous tuning and improvements.
- Establish and maintain detection and response playbooks, including alert triage, escalation paths, documentation requirements, and post-incident follow-up.
Incident Response & Threat Prevention
- Own and maintain the Security Incident Response Plan, including severity definitions, roles and responsibilities, evidence handling, escalation paths, and internal/external communication procedures.
- Lead security incident response from identification through containment, eradication, recovery, and lessons learned.
- Perform root-cause analysis and coordinate corrective actions with IT administrative staff and relevant stakeholders.
- Proactively implement threat prevention measures: hardening, secure configuration baselines, conditional access/MFA enforcement support, and policy-driven risk reduction.
- Maintain an incident register covering actual, attempted, and suspected security incidents (including phishing attempts), investigations performed, and outcomes.
Compliance Enablement (CMMC L2 / NIST Controls)
- Maintain the System Security Plan (SSP) and Plan of Actions & Milestones (POA&M) for in‑scope systems, ensuring clear implementation statements, ownership, and evidence references.
- Support definition and maintenance of the CUI boundary, including systems, users, endpoints, networks, and data flows.
- Translate CMMC and NIST control requirements into concrete configurations, procedures, and ongoing monitoring activities across Microsoft 365, on‑prem infrastructure, and restricted or air‑gapped environments.
- Collect, organize, and maintain audit‑ready evidence to support internal assessments, customer diligence, and third‑party assessments.
- Define and maintain a centralized logging strategy (SIEM) spanning cloud and on‑prem environments, including ingestion of logs from identity systems, endpoints, email, servers, firewalls, VPNs, and IDS/IPS platforms.
On‑Prem & Air‑Gapped Security
- Establish and operate secure data transfer procedures for air‑gapped and restricted environments, including removable media governance, integrity validation, malware scanning, and chain‑of‑custody documentation.
- Partner with Network Architecture to design and maintain secure monitoring architectures for restricted and air‑gapped environments, including TAP/SPAN placement, IDS deployment, and segmentation alignment with OT/ICS security best practices
Security Engineering & Integrations
- Support integrations between cloud-based services and the Microsoft security/compliance ecosystem (e.g., log sources, alerting, ticketing workflows, SSO/identity integrations).
- Contribute to automation where appropriate (e.g., scheduled scripts, workflows, or playbook-style response actions).
Cross-Functional Collaboration & Communication
- Work closely with IT and engineering teams to ensure smooth operations and secure-by-default practices.
- Document, categorize, and prioritize security issues to ensure efficient escalation and resolution.
- Enforce approved security, compliance, and privacy policies and contribute to ongoing policy development and improvement.
- Collaborate with Network Architecture on secure network design, segmentation strategy, and enforcement controls including firewall policy, IDS/IPS, and Zero Trust network principles.
- Collaborate with Network Architecture on secure network design, segmentation strategy, and enforcement controls including firewall policy, IDS/IPS, and Zero Trust network principles
- Implement privacy impact assessments (PIAs) for new systems or processes involving personal data.
- Partner with Legal and HR to document the company’s GDPR and CCPA applicability position, including the basis where such laws do not apply.
- Support inclusion of appropriate data privacy and security terms in third‑party contracts and service agreements.

- Experienece: 7+ years of experience in security administration, security operations, compliance operations, or adjacent IT roles with direct security responsibility.
- Demonstrated hands‑on experience administering Microsoft 365 security and compliance services, including Microsoft Purview and Microsoft Defender in an enterprise environment.
- Proven background in security incident response, investigation, and documentation in regulated or high‑risk environments.
- Working knowledge of system security best practices, access control, secure configuration, and audit logging.
- Strong written and verbal communication skills; able to translate technical security risk into clear, actionable steps and documentation.
- Comfortable operating as a self‑directed individual contributor in a fast‑paced and evolving environment.
- Excellent technical and interpersonal communication skills; able to translate security risk into actionable steps.
- Comfortable in a fast-paced, dynamic, and ambiguous environment.
