Cyber Security Engineer

Job#: 3015181

Job Description:

Our great client has an immediate opening for a Cybersecurity Engineer. If you are interested please apply with resume to .

We're seeking a senior cybersecurity engineer to design, build, and operationalize enterprise grade- data protection capabilities anchored in Microsoft E5. You will lead engineering for Microsoft Purview (Information Protection & DLP, eDiscovery/Audit), Sensitivity Labels, and related guardrails-integrating telemetry and enforcement through Zscaler, CrowdStrike, and Splunk. This role bridges secure-by-default platform engineering with pragmatic automation to protect regulated data (e.g., PHI/PII) at scale. Senior leadership has prioritized accelerating Copilot and E5 controls adoption, creating a high impact- opportunity to shape how we protect data across SaaS and AI workloads.

What You'll Do

Engineer secure-by-default E5 data protection

• Design and implement Microsoft Purview DLP policies (endpoint, Exchange, SharePoint, OneDrive, Teams) and Sensitivity Label taxonomy with automated enforcement paths.
• Build policy-as-code pipelines (CI/CD) to version, test, and deploy DLP rules, label configs, and governance artifacts in multiple environments.

Integrate Zscaler, CrowdStrike, and Splunk

• Connect Zscaler SSE inspection with Purview controls; route events to Splunk for analytics, dashboards, and detections that close visibility and enforcement loops.
• Leverage CrowdStrike telemetry (e.g., Falcon/Shield) to correlate endpoint behaviors with data movement signals for insider-risk and exfiltration use cases.

Build automations & guardrails

• Develop services and workflows (e.g., Azure Functions, Logic Apps, Graph API) to auto-remediate mislabels, revoke risky shares, and notify data owners.
• Implement secure-by-default configuration baselines and drift detection for E5 security controls (MCAS/Defender for Cloud Apps, Conditional Access, etc.).

Operate and continuously improve

• Own reliability for data protection pipelines: SLIs/SLOs, runbooks, and incident playbooks in partnership with Insider Risk team.
• Create Splunk content (data models, dashboards, correlation searches) aligned to exfiltration, anomalous access, and label violations.
• Partner with Privacy and Compliance for audit-ready controls (eDiscovery/Audit), evidence, and exception processes.

Collaborate across security & platform teams

• Work with PSO, IAM, and Insider Risk to align label taxonomy and enforcement with business workflows and least-privilege access.
• Provide technical leadership and mentoring for engineers/analysts rolling out new E5 features and operational support.

Required Qualifications

• 5+ years engineering experience in enterprise security or platform engineering; hands-on- with Microsoft E5 security stack (Purview DLP, Information Protection, eDiscovery).
• Proven expertise building policy-as-code for DLP/labels (GitHub/Azure DevOps), and automating Graph/PowerShell administration.
• Demonstrated ability to design secure-by-default guardrails and support rapid SaaS/AI adoption (including Copilot) without compromising compliance.

Nice to Have

• Strong background in data protection for regulated data (PII/PHI), insider-risk detection, and evidence-driven investigations.
• Production experience with Zscaler (SSE/ZIA/ZPA), CrowdStrike (Falcon APIs/telemetry), and Splunk (TA configs, CIM, correlation searches).
• Experience migrating from legacy DLP (e.g., Forcepoint) to Microsoft DLP; building vendor-neutral dictionaries and detection logic.
• Familiarity with MCAS/Defender for Cloud Apps, conditional access policies, and SSPM evaluations.
• Background in HIPAA/PHI audit support and exception governance workflows.

Success Metrics (first 6-12 months)

• DLP policy efficacy: reduction in unauthorized shares/exports; mean time to remediate violations.
• Label coverage & accuracy: % of sensitive content labeled; false positive/negative rate trends.
• Telemetry integration: end-to-end event flow (Purview Zscaler/CrowdStrike Splunk) with actionable detections.
• Secure-by-default adoption: # of guardrails implemented; drift detected/resolved; Copilot controls baselined.
• Audit readiness: evidence completeness for eDiscovery/Audit; exception closure rates.

Tools & Technologies (primary)

• Microsoft E5 / Purview: Information Protection, DLP, eDiscovery/Audit, Insider Risk
• Zscaler (SSE/ZIA/ZPA), CrowdStrike (Falcon/Shield), Splunk (CIM, ES)
• Automation: GitHub, Graph API, PowerShell, Azure Functions/Logic Apps
• Data flows: Exchange/SharePoint/OneDrive/Slack, endpoints, web proxies, CASB/SSE
