Job Description

JOB DESCRIPTION

Were 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 guardrailsintegrating 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 Youll 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 612 months)

DLP policy efficacy: reduction in unauthorized shares/exports; mean time to remediate violations.

Label coverage & accuracy: % of sensitive content labelled; 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
