Job Description
At P&G, your career is built to scale with our iconic brands like Ariel ® , Safeguard ® , Tide ® , Head & Shoulders ® , Old Spice ® , and Vicks ®.
Ready to join the team that powers our iconic brands? Here’s what you’ll be doing:
We are seeking a Senior Email Security & Reliability Engineer to comprehensively own our global messaging defense platform. This role perfectly balances Core Security Engineering (designing mail flows, tuning policies, and stopping threats) with Reliability Engineering —specifically Site Reliability Engineering (SRE) to ensure the uptime of our mail routing, and Security Reliability Engineering (SecRE) to guarantee our detection pipelines and automated response systems operate flawlessly.
A heavy focus of this position is driving low-code/no-code playbook automation and orchestration to maximize operational efficiency for both the Email Security and broader Security Operations Center (SOC) teams. You will maintain our multi-layered stack—centered around Proofpoint (inline) and Microsoft Defender for Office 365 (non-inline post-delivery)—while scaling an active automation framework that leverages dynamic user risk assessments to trigger cloud-based browser isolation for our most targeted users.
Job Overview
This role requires a unique mix of messaging security expertise, automation scripting, and reliability engineering. While this is not a pure software development role, you will heavily utilize Python and PowerShell to build integrations, automate repetitive workflows, and orchestrate responses using modern SOAR platforms. The role also expects the heavy integration and use of Artificial Intelligence (AI) tools in day-to-day work—ranging from maximizing AI-driven security telemetry to utilizing AI capabilities to accelerate engineering, documentation, and troubleshooting tasks. Your goal is to ensure mail routing never drops, security controls fail-securely, and the SOC benefits from high-fidelity, automated email threat containment.
Key Responsibilities
Automation, SOAR, & SOC Integration
SOAR Orchestration: Design, build, and optimize automated incident response playbooks within Cortex XSOAR and Torq to accelerate threat containment and reduce manual analyst overhead.
Efficiency Optimization: Develop automation workflows to improve operational efficiency, streamline alert triaging, and eliminate manual processes for both Email Security operations and the centralized SOC.
API Integration Management: Build and maintain reliable integrations linking Proofpoint, Microsoft Defender, and other security tools via APIs to ensure seamless telemetry sharing and orchestration.
Scripted Automation: Write targeted, efficient scripts in Python and PowerShell to parse email headers, query security logs, manipulate data objects, and bridge gaps between disparate security solutions.
Core Email Security Engineering
SEG Policy Management: Configure and fine-tune inbound/outbound rules within Proofpoint Enterprise Gateway to block phishing, spam, malware, and business email compromise (BEC).
Multi-Layered Threat Hunting: Monitor and tune Microsoft Defender for Office 365 in a non-inline configuration to detect, investigate, and auto-remediate malicious emails that bypass the gateway perimeter.
Email Governance: Enforce, troubleshoot, and audit domain health and brand protection configurations via SPF, DKIM, and DMARC protocols.
Incident Triage & Analysis: Investigate complex SMTP routing anomalies, resolve delivery failures, and support the SOC during high-priority email-borne campaigns.
SRE & SecRE (Reliability Engineering)
Infrastructure Reliability (SRE): Own the availability, performance, and operational health of enterprise mail routing. Build monitoring dashboards, establish alerting thresholds, and define Service Level Indicators/Objectives (SLIs/SLOs) for mail delivery.
Control Pipeline Reliability (SecRE): Treat security controls as software systems. Ensure…
