Role Purpose
As the Endpoint Security Engineer, you are accountable for defining endpoint hardening standards and engineering baseline security controls across all Windows, macOS, and Linux device estates.

Operating as a hands-on technical lead, you will drive endpoint risk reduction across the enterprise. By configuring advanced EDR/XDR controls, managing device compliance frameworks, and supporting incident response teams, you will ensure end-user devices are continuously defended against modern compromise techniques.

In this role, you will lead and manage the following domains:

Endpoint Hardening & Baselines: Defining, implementing, and enforcing security baselines across Windows, macOS, and Linux fleets.

EDR/XDR Control Engineering: Managing and tuning Microsoft Defender endpoints and security capabilities.

Device Compliance Frameworks: Designing compliance policies that enforce endpoint health prior to granting corporate resource access.

Vulnerability & Posture Reduction: Leading targeted initiatives to mitigate system vulnerabilities, OS flaws, and configuration drift.

Security Reviews & Incident Support: Conducting technical endpoint security reviews and assisting incident response teams during major investigations.

Key Skills & Qualifications
- Bachelor's degree in Computer Science, Information Technology, Cybersecurity, or a related field (or equivalent practical experience).

- A minimum of 5–7 years' technical experience in endpoint security engineering, OS hardening, and endpoint management at scale.

- Deep engineering knowledge of multi-OS security architectures (Windows, macOS, Linux) and cross-platform EDR deployment.

- Relevant certifications such as Microsoft Certified: Security Operations Analyst Associate (SC-200), GIAC Endpoint Asset Protection (GCED), or CISSP are highly desirable.

Security Expertise & Architecture
Deep understanding of OS internal security structures (Windows Defender, macOS Security Frameworks, Linux PAM/AppArmor/SELinux) and local attack mitigation controls.

Tooling & Technical Proficiency
Proficiency in Microsoft Defender for Endpoint, Intune, JAMF, Microsoft Security Baselines, CIS Benchmarks, and endpoint management systems.

Risk Management & Prioritisation
Ability to prioritize OS-level misconfigurations and endpoint vulnerabilities based on active exploit availability and local device access rights.

Governance, Process & Control Design
Experience designing automated device compliance policies, device health attestation checks, and local privilege management controls.

Service Delivery & Operational Management
Proven ability to manage endpoint security agent coverage, maintain health telemetry across global device estates, and minimize agent conflicts.

Data Analysis, Reporting & Insight
Skilled in analyzing endpoint telemetry, KQL querying, and generating clear health dashboards for device compliance and security posture.

Stakeholder Management & Influence
Ability to partner with workplace platform engineering teams to push security updates and baseline policy changes without disrupting end-user productivity.

Threat Intelligence Integration
Ability to translate threat intelligence indicators (IoCs) and adversary techniques (MITRE ATT&CK) into tailored endpoint detection and block rules.

Leadership & Collaboration
Proven ability to lead technical endpoint security workstreams, provide clear remediation directions, and mentor junior operational staff.

Continuous Improvement & Automation
Experience driving security automation through script-based remediation (PowerShell, Bash, Python) and unified endpoint management integrations.

Key Accountabilities & Success Measures
Endpoint Hardening & Security Baselines
Accountability: Architect, deploy, and maintain standardized security baselines for all Windows, macOS, and Linux endpoints.
Success Measures: Greater than 98% compliance rate with established OS security baselines across the entire enterprise estate; 100% of managed devices bound by strict compliance and attestation requirements.

Defender Suite Engineering & Telemetry
Accountability: Engineer Microsoft Defender capabilities, optimize detection engine rules, and ensure full agent health across all OS platforms.
Success Measures: >99% agent deployment health and active reporting across all connected devices; Dynamic detection policy coverage mapped directly against top MITRE ATT&CK techniques.

Vulnerability & Risk Reduction Initiatives
Accountability: Drive endpoint risk reduction programs aimed at mitigating configuration flaws, unpatched software, and high-risk local permissions.
Success Measures: Measurable structural reduction in high and critical endpoint security posture gaps; MTTR for critical endpoint configuration drift kept within defined SLA targets.
