We're hiring a hands-on delivery engineer to take Cortex deployments from initial setup through production rollout and keep them running well afterward. You'll own the technical execution of Cortex projects for our customers: standing up the platform, onboarding data sources and endpoints, tuning detections, and building automation playbooks. Once a deployment goes live, you'll also pick up operational issues for it and for other customers.

Responsibilities

• Configure and deploy Cortex XDR, XSIAM, and XSOAR, translating architecture and design decisions into a working environment
• Lead endpoint agent rollout, log source and data onboarding, and integration configuration across a customer's security and IT stack
• Tune detection rules and correlation logic to reduce noise and align with each customer's environment and threat profile
• Build and maintain XSOAR playbooks that automate response actions and reduce manual triage work
• Troubleshoot production issues across the platform: agent health, ingestion failures, integration breakage, playbook errors, and detection gaps
• Write clear documentation and runbooks
• Escalate to Palo Alto support channels when an issue requires vendor involvement, and manage the case through to resolution
• Validate a project's technical scope against the signed SOW before kickoff, and flag gaps or risks early

Requirements

• At least 5 years of hands-on experience in security operations or security engineering, including direct, production experience deploying and operating Palo Alto Cortex (XDR, XSIAM, and/or XSOAR)
• Demonstrated experience taking a Cortex deployment from initial configuration through go-live: agent rollout at scale, data source onboarding, and integration setup
• Strong troubleshooting ability across Windows, Linux, and macOS endpoints, plus solid networking fundamentals
• Scripting proficiency in Python and/or PowerShell, and comfort reading and modifying XSOAR playbooks
• Experience integrating third-party tools and APIs into a SIEM or SOAR platform
• Ability to work independently across several customer environments at once, in a project and ticket-driven delivery model rather than a single dedicated account.
• Strong written documentation skills

Advantage:

• Cortex XDR or XSIAM certification, or equivalent Palo Alto platform certification such as PCNSE
• Prior experience delivering security projects at a systems integrator, reseller, or professional services firm, where work is scoped against a statement of work rather than an open-ended internal mandate
• Familiarity with cloud platforms (AWS, Azure, or GCP) for onboarding cloud-based log sources
• Exposure to Cortex Cloud or CNAPP concepts, given the ongoing convergence between Cortex and Prisma Cloud
• Experience with a second SIEM or EDR platform, useful when working in mixed-vendor environments
