[Hiring] Endpoint Engineer III @ECS Tech Inc

Role Description

The Endpoint Engineer III is responsible for supporting the engineering, implementation, administration, and optimization of enterprise endpoint security and data protection technologies. This role works closely with the Security Engineering Manager, security operations teams, enterprise IT teams, infrastructure teams, and platform owners to ensure endpoint security controls are effectively deployed, maintained, and integrated across client environments. The Endpoint Engineer III serves as a senior technical resource for endpoint security along with supporting the Data Loss Prevention (DLP) program, providing advanced troubleshooting, platform administration, policy management, integration support, and technical guidance. The engineer will contribute to the continuous improvement of endpoint protection, data protection, security automation, and operational processes that strengthen the organization's overall cybersecurity posture.

Responsibilities

• Administer, maintain, configure, and optimize enterprise endpoint security technologies including EDR/EPP, endpoint security agents, device controls, host-based security controls, and related technologies.
• Configure, administer, maintain, and optimize enterprise Data Loss Prevention and data protection platforms across endpoint, cloud, email, web, and other supported channels.
• Develop, implement, maintain, and tune endpoint and data protection security policies and configurations to provide appropriate protection while minimizing unnecessary operational impact.
• Support the implementation and operation of data classification, labeling, encryption, device control, and other technical controls designed to protect sensitive organizational information.
• Support enterprise deployment, upgrades, migrations, configuration changes, agent/sensor health, and lifecycle management of endpoint security and DLP technologies.
• Collaborate with enterprise IT, cloud, identity, network, infrastructure, and security teams to integrate endpoint security and data protection technologies with enterprise systems and services.
• Serve as a senior escalation point for complex endpoint security and DLP platform issues, including agent/sensor problems, policy conflicts, performance issues, integration failures, and unexpected control behavior.
• Provide technical expertise during security investigations involving endpoint activity, potential data exposure, DLP policy violations, malware, suspicious activity, and other endpoint security events.
• Analyze endpoint and DLP platform activity to identify false positives, policy gaps, configuration issues, and opportunities to improve security effectiveness and user experience.
• Develop and maintain scripts, integrations, and automation workflows to improve endpoint security administration, platform management, data protection operations, reporting, and response activities.
• Monitor the health, deployment status, reliability, and performance of security tool platforms, agents, sensors, policies, integrations, and supporting infrastructure.
• Provide technical guidance and mentorship to other engineers, assist with complex engineering initiatives, and contribute to technical decisions related to endpoint security.
• Develop and maintain engineering documentation, platform configurations, policy documentation, troubleshooting procedures, implementation guides, operational runbooks, and knowledge articles.
• Identify opportunities to strengthen endpoint security and data protection coverage, improve platform reliability, optimize policies and configurations, increase automation, and improve engineering and operational workflows.

Qualifications

• Minimum of 5–8 years of cybersecurity or security engineering experience supporting enterprise security operations environments.
• Hands-on experience administering and troubleshooting enterprise endpoint security technologies such as EDR/EPP, endpoint security agents, host-based security controls, device control, and related technologies.
• Experience with enterprise endpoint security technologies such as Microsoft Defender for Endpoint, CrowdStrike Falcon, Trellix, or similar platforms.
• Strong understanding of DLP concepts, sensitive data identification, data classification and labeling, encryption, device control, and protection of data at rest, in use, and in transit.
• Experience implementing, testing, troubleshooting, and tuning DLP policies and rules, including reducing false positives and evaluating the operational impact of data protection controls.
• Strong understanding of enterprise endpoint environments, Windows operating systems, identity and access technologies, networking concepts, cloud services, and security architecture.
• Demonstrated ability to troubleshoot complex endpoint security issues involving agents, operating systems, policies, applications, network connectivity, and security platform integrations.
• Experience using scripting or automation to support security engineering, platform administration, troubleshooting, or operational activities.
• Familiarity with cybersecurity and data protection frameworks and standards such as NIST Cybersecurity Framework, CIS Critical Security Controls, and ISO 27001.

Requirements

• Able and willing to obtain a US Security Clearance.
• Participates in on-call support to assist with security incident response, operational issues, and investigation activities to maintain continuous SOC coverage and response capabilities.

Benefits

• Salary Range: $130,000-$160,000
