Senior Security Endpoint Engineer

Dragos, Inc. is a global leader in xOT cybersecurity, dedicated to protecting critical infrastructure systems. The Senior Security Endpoint Engineer will manage the full lifecycle of endpoint security and ensure a seamless employee experience while maintaining security posture.

Responsibilities:

• Own the complete endpoint lifecycle including provisioning, configuration, enrollment, refresh, and decommissioning across all supported platforms while maintaining standard build configurations and baseline images
• Administer and optimize the endpoint detection and response (EDR) platform, including sensor deployment, detection tuning, and response policy optimization to reduce alert noise while preserving security effectiveness
• Lead endpoint-focused incident response activities including triage, containment, forensic data collection, and post-incident review; develop and maintain incident response runbooks for endpoint threat scenarios
• Establish and manage the endpoint patching program across operating systems and third-party software, define patch compliance SLAs by severity level, and coordinate patching efforts with Infrastructure and Systems Engineering teams
• Administer the mobile device management (MDM) platform for corporate and BYOD devices, manage mobile configuration profiles, compliance policies, and ensure mobile endpoint visibility within security tooling
• Act as the escalation point for complex endpoint issues beyond helpdesk capability, maintain user-facing documentation and guidance, and gather staff feedback to reduce unnecessary policy burden while preserving security controls
• Build and maintain endpoint automation for configuration management, compliance verification, remediation workflows, and reporting; evaluate new endpoint tools and capabilities and contribute endpoint-focused priorities to the security engineering roadmap

Requirements:

• 5–8 years of hands-on experience in endpoint security, endpoint management, or a combined security/IT operations role
• Deep working knowledge of EDR platforms: deployment, tuning, policy management, and incident response workflows
• Demonstrated experience managing endpoints across Windows, macOS, and Linux at scale
• Hands-on MDM administration experience (corporate devices and/or BYOD) across iOS and Android
• Practical experience with patch management programs including SLA definition, compliance tracking, and exception handling
• Proficiency with scripting and automation (PowerShell, Bash, Python, or equivalent) for endpoint management and operational workflows
• Familiarity with vulnerability management workflows and how endpoint patching integrates into the broader program
• Strong written communication skills — you can document a configuration decision and explain a security risk to a non-technical audience without losing accuracy in either case
