Lead Endpoint Cybersecurity Engineer

Summary

The Lead Endpoint Cybersecurity Engineer is a senior technical engineering role responsible for the design, deployment, maintenance, testing, troubleshooting, and continuous improvement of enterprise endpoint cybersecurity technologies. The engineer will provide deep technical leadership across endpoint security platforms and their supporting infrastructure, ensuring security applications are stable, performant, effectively integrated, and capable of operating at enterprise scale.

The position builds on the existing internal Endpoint Engineering charter, which describes responsibilities for designing, deploying, maintaining, and optimizing endpoint security solutions across the enterprise. The existing Senior Endpoint Cybersecurity Engineer requirement similarly emphasizes endpoint-security solution design and deployment, EDR and deception technology, detection tuning, technology evaluation, incident-response collaboration, architecture, and mentoring.

This role will have two strategic deployment responsibilities:

• Enterprise Deception Framework: Lead the endpoint-engineering activities required to deploy, integrate, validate, operate, and optimize the company's enterprise cyber deception capability.
• AI Detection and Response (AIDR): Lead endpoint engineering and technical implementation activities associated with evaluating and deploying an endpoint-based AI Detection and Response capability designed to identify and respond to emerging AI and agentic-AI threats.

Key Responsibilities and Duties

• Serve as a technical lead for enterprise endpoint cybersecurity technologies across Windows, macOS, Linux, VDI, and server environments as applicable.
• Design, configure, deploy, maintain, upgrade, and troubleshoot endpoint cybersecurity applications and agents.
• Provide senior-level break/fix and problem-management support, including root-cause analysis for application failures, agent health issues, policy conflicts, deployment failures, integration failures, and endpoint instability.
• Perform application lifecycle activities including upgrades, configuration changes, policy tuning, regression testing, deployment validation, and rollback planning.
• Develop technical standards, runbooks, operating procedures, implementation documentation, and support documentation.
• Identify opportunities for automation through scripting, APIs, configuration-management platforms, and other engineering mechanisms.
• Troubleshoot agent installation, upgrade, communication, policy, interoperability, and stability issues.
• Coordinate complex incidents with cybersecurity, infrastructure, desktop engineering, vendors, and application owners.
• Identify conflicts between existing and proposed cybersecurity agents.
• Perform stability, coexistence, upgrade, rollback, failure-mode, and regression testing.
• Document findings and provide technical go/no-go recommendations before production deployment.
• Establish performance monitoring following initial deployment waves.
• Engineer the endpoint components of the Deception Framework across supported workstation and server populations.
• Perform proof-of-concept and production-readiness testing.
• Validate deceptive files, credentials, registry artifacts, sessions, processes and related endpoint lures as appropriate to approved use cases.
• Test failure conditions and confirm endpoint stability when deception components are unavailable or impaired.
• Validate integration of Deception telemetry with enterprise security monitoring and response systems.
• Support deployment waves and troubleshoot installation, communications, configuration, and endpoint-side operational issues.
• Develop deployment procedures, engineering standards, configuration documentation, troubleshooting guides, and operational runbooks.
• Assist with tuning and continuous improvement following production deployment.
• Ensure endpoint implementation adheres to architecture, privacy, security, change-management and production-safety requirements.
• Validate integration with existing EDR/XDR, SIEM, SOAR, identity and security operational workflows.
• Conduct controlled performance testing to quantify CPU, memory and other endpoint overhead.
