Who we are looking for We are looking for a
Senior Security Engineer, Cyber Defense Platforms reporting directly to the
Head of Defensive Engineering and Architecture . This role is hands-on and engineering-focused, responsible for
hardening enterprise endpoints (workstations and servers) to reduce attack surface across the environment.
You will enforce secure configurations, minimize unnecessary services, and support execution control mechanisms in alignment with established security standards and architectural guidance. The role requires close collaboration with
Network Security (NetSec) teams to reduce endpoint-to-network exposure (e.g., restricted protocol usage, dependency reduction, and Zero Trust enforcement impacts), as well as with
Data Security (DataSec) teams to support endpoint controls that protect sensitive data, prevent unauthorized tools, and ensure alignment with approved software and data protection policies
Why this role is important to us The team you will be joining is part of the
Integrated Defensive Engineering and Architecture(IDEA) - Cyber Defense function , which is critical to reducing enterprise cyber risk and strengthening resilience against modern threats.
This role is vital because a significant portion of enterprise risk resides at the
endpoint layer , where misconfigurations, excess privileges, and unapproved software are commonly exploited. By systematically reducing attack surface and enforcing strong endpoint controls, this role directly contributes to:
- Lower likelihood of ransomware and malware propagation
- Stronger Zero Trust posture
- Improved protection of sensitive and regulated data
- Measurable reduction in cyber risk at scale
What you will be responsible for As a
Senior Security Engineer, Cyber Defense Platforms , you will:
- Design, implement, and maintain endpoint hardening standards across workstations and servers, aligned with CIS benchmarks, internal standards, and risk-based guidance
- Reduce enterprise attack surface by disabling unnecessary services, features, protocols, and tooling across endpoint environments
- Engineer and support execution control mechanisms, including application control, script control, and prevention of unauthorized software
- Partner with NetSec teams to reduce endpoint-to-network exposure, including protocol restrictions, dependency mapping, and Zero Trust enforcement considerations
- Support DataSec initiatives by enabling endpoint-level controls that protect sensitive data and enforce approved software and data handling policies
- Identify and assess unapproved or risky endpoint software, working with stakeholders on remediation, allow-listing, or removal paths
- Collaborate with platform, infrastructure, and operations teams to ensure controls are scalable, reliable, and operationally sustainable
- Contribute to security architecture documentation, standards, and roadmaps related to endpoint and defense platforms
What we value These skills will help you succeed in this role
Strong
security engineering mindset with the ability to translate risk into practical, enforceable technical controls
Deep problem-solving skills and the ability to operate effectively in complex, large-scale enterprise environments
Experience designing and deploying security controls across
large scale multi-region environments
Ability to collaborate across security, infrastructure, and application teams while maintaining a strong security posture
Clear communication skills to explain trade-offs, risks, and control impacts to technical and non-technical stakeholders
Education & Preferred Qualifications Bachelor's degree in Computer Science, Engineering, Cybersecurity, or a related discipline (or equivalent experience)
8+ years of experience in security engineering, endpoint security, or defensive cyber roles
Strong hands-on experience with
endpoint security platforms (e.g., EDR, application control, configuration management, hardening frameworks)
Experience with
Zero Trust principles , endpoint-to-network control models, or execution control technologies
Security certifications such as
CISSP, GCED, GSEC, OSCP, or relevant vendor certifications are a plus
Additional requirements Experience working in
regulated or large enterprise environments preferred
Ability to influence and drive security improvements without direct authority
Occasional after-hours support for high-risk changes or security incidents, as required
Work Requirement Hybrid work model (specific in-office requirements aligned with team and location policy)
Standard business hours with flexibility to support global teams and critical security initiatives
Salary Range: $90,000 - $157,500 Annual
The range quoted above applies to the role in the primary location specified. If the candidate would ultimately work outside of the primary location above, the applicable range could differ.
