Full Job Description

Contract to Hire
McKinney, TX (Hybrid)

Responsibilities

Monitor Proofpoint dashboards, alerts, quarantine queues, digest activity, abuse mailboxes, and user-reported phishing submissions.
Triage and investigate email threats including phishing, business email compromise (BEC), impersonation, malware delivery, spam, and fraudulent communications.
Determine risk using email artifacts such as headers, sender reputation, authentication results (SPF/DKIM/DMARC), URLs, attachments, domains, and message content.
Use Proofpoint search / message tracking capabilities to identify campaign scope and locate malicious messages across impacted mailboxes.
Execute containment actions in Proofpoint: block/deny-list malicious senders, domains, URLs, and other indicators; manage allow/deny logic where appropriate.
Drive remediation and takedown actions (e.g., message removal guidance, user notification, escalation to IR/SOC when needed).
Administer and continuously tune Proofpoint policies, detection rules, and protection controls to improve efficacy and reduce false positives.
Review quarantined messages and determine whether messages should be released, blocked, or escalated, documenting rationale and outcomes.
Maintain and refine block lists, allow lists, and exception workflows with strong change control and documentation.
Monitor and assist with SPF, DKIM, and DMARC posture to reduce spoofing/impersonation risk.
Identify misconfigurations and coordinate corrective actions with domain owners, Microsoft 365 administrators, and relevant business stakeholders.
Support investigations involving account compromise, suspicious mailbox rules/forwarding, unusual email access patterns, and suspicious outbound activity.
Coordinate with SOC, IAM, Incident Response, Microsoft 365, Legal, HR, and business leaders during sensitive investigations.
Document investigation steps, findings, remediation actions, recurring attack patterns, and lessons learned.
Create and maintain SOPs and response playbooks for Proofpoint-driven workflows (triage, quarantine review, campaign response, indicator blocking).
Track and report email-security metrics: message volume, blocked threats, phishing trends, user reporting rates, false positives, remediation SLAs, and emerging TTPs.
Identify opportunities to automate repetitive tasks across investigation, containment, and reporting.
Support email-security projects such as Proofpoint enhancements, platform upgrades, policy changes, onboarding new domains/business units, and M&A-related integration.

Required Skills

Demonstrated experience using Proofpoint in an operational security role (monitoring, quarantine triage, investigations, policy tuning).
Strong knowledge of phishing/BEC tradecraft and email analysis (headers, routing, URLs/attachments, domain reputation).
Working understanding of Microsoft 365 / Exchange Online concepts and email authentication (SPF/DKIM/DMARC).
Strong analytical skills, attention to detail, sound judgment, and clear communication with both technical and non-technical users.
Ability to document work cleanly and operate effectively in an alert-driven environment.

Estimated Min Rate: $110000.00
Estimated Max Rate: $130000.00
