IDR, ensuring scan coverage, remediation tracking, and automation where possible. - Implement and maintain hardened security baselines across all operating systems using Intune, Group Policy, CIS Benchmarks, and EDR configuration controls.
- Maintain complete visibility of endpoint and cloud security tool deployment (EDR, DLP, vulnerability scanning, logging agents), ensuring consistent coverage and compliance.
- Serve as a lead investigator for alerts from EDR, SIEM, Rapid7, DLP, WAF, and cloud‑native security platforms.
- Conduct threat hunting, deep‑dive log analysis, malware investigation, and IOC analysis across endpoints and AWS environments.
- Work closely with NOC, infrastructure, cloud engineering, and endpoint teams to drive rapid and effective response to incidents.
- Support secure deployment and configuration of AWS services, ensuring alignment with best practices, identity controls, encryption standards, and logging/monitoring (Cloud Trail, Cloud Watch, Guard Duty, IAM, VPC, KMS).
- Partner with cloud and Dev Ops teams to embed security into CI/CD pipelines, IaC templates, and cloud architecture decisions.
- Assess cloud workloads for misconfigurations, excessive permissions, and exposure using Rapid7, AWS Config, and native cloud posture tools.
- Own lifecycle management of security tools, including patching, upgrades, feature enablement, and decommissioning.
- Monitor new vulnerabilities affecting security systems (EDR, DLP, SIEM, agents, cloud services) and coordinate remediation.
- Participate in tool evaluations, POCs, vendor assessments, and ongoing modernization efforts.
- Maintain operational security documentation: SOPs, configuration standards, runbooks, and exception logs.
- Participate in on‑call rotation and provide occasional after‑hours support during incidents or maintenance windows.
- Bachelor’s degree in Computer Science, Information Security, or equivalent hands‑on experience.
- 5+ years of experience in security engineering, endpoint/cloud security, or detection engineering roles.
