The Cyber Endpoint Security Systems Engineer is responsible for the technical architecture detection engineering automated integration platform modernization and attack surface reduction across enterprise endpoint ecosystems. This role engineers and scales the endpoint security platform infrastructure (e.g. architecting resilient topologies designing migrations to modern capabilities) develops detection-as-code capabilities architects modern API integrations and builds automated containment workflows to enhance defensive posture while minimizing operational overhead.

Responsibilities:

• Architect test and deploy resilient high-availability enterprise endpoint security platform topologies (e.g. multi-tier Trellix ePO clustered databases load-balanced Agent Handlers in DMZs and segmented cloud environments).
• Lead strategic modernization initiatives including re-architecting legacy on-premises endpoint security infrastructure.
• Design and test migration paths for legacy point products.
• Engineer multi-platform agent compatibility across enterprise operating systems microservices containerized workloads and non-persistent VDI environments.
• Formulate platform sizing compute/storage scalability models network bandwidth throttles and disaster recovery architectures (RTO/RPO) for all endpoint security management systems.
• Develop test and deploy custom behavioral detection rules (mapped directly to the MITRE ATT&CK framework) to catch novel adversary tradecraft persistence mechanisms and lateral movement.
• Engineer host-level Attack Surface Reduction (ASR) baselines including Windows Defender Application Control (WDAC) Trellix Application Control/Solidcore execution control baselines Credential Guard Exploit Guard and Linux kernel security modules (SELinux/AppArmor).
