Position Overview. Meridian LilyLifestyle

Description

The Senior Security Controls Engineer designs, implements, and continuously improves technical security controls that reduce risk across on premises, cloud, and endpoint environments. This role specializes in hardening, benchmark compliance, configuration risk reduction, compensating controls for nonpatchable vulnerabilities, and control automation  engineer partners with IT operations, platform teams, and risk/compliance to ensure controls are effective, measurable, and audit‑ready.

Director of Information Security

Boise,  - Onsite

Fulltime

0‑10% (as needed for site visits, projects, or audits)

May participate in a rotating on‑call schedule for security engineering support

• Engineer and maintain preventive and detective controls across endpoints, servers, network, identity, and cloud services (Azure/AWS).
• Lead configuration hardening initiatives using industry benchmarks (e.g., CIS) and establish secure configuration baselines for common platforms (Windows, Linux, network devices, cloud services).
• Design compensating controls for vulnerabilities that cannot be remediated through patching (e.g., configuration changes, isolation, access controls, WAF rules, EDR policy tuning, segmentation).
• Own the technical control lifecycle: control requirements design, implementation, testing/validation, monitoring, continuous improvement.
• Develop and maintain control‑as‑code and automation (Power Shell/Python/Terraform/CI‑CD) to deploy and enforce configurations consistently.
• Implement configuration compliance monitoring, drift detection, and remediation workflows; integrate with ticketing/ITSM for exception handling.
• Partner with Vulnerability Management to translate findings into durable mitigations (hardening, compensating controls, secure defaults) and reduce recurring exposure.
• Collaborate with SOC/IR to improve detections and containment policies aligned to threats and incidents; tune controls based on lessons learned.
• Produce audit‑ready evidence: control narratives, diagrams, test results, screenshots/exports, and KPI dashboards.
• Maintain standards, procedures, and runbooks for control engineering; mentor junior engineers and provide technical leadership to cross‑functional teams.

• Secure configuration baselines and reference architectures for key platforms.
• Benchmark compliance reporting (coverage, drift, exceptions) with remediation plans.
• Compensating control designs and validation artifacts for non‑patchable risk.
• Automation modules/scripts (policy‑as‑code) to deploy or enforce controls at scale.
• Control test plans, operational metrics, and audit evidence packages.

• 7+ years in security engineering, systems engineering, or infrastructure engineering with a strong focus on security controls and hardening.
• Hands‑on expertise with Windows and Linux hardening, identity controls, and endpoint security control configuration.
• Experience implementing benchmark‑based configuration standards (e.g., CIS) and managing exceptions/risk acceptances.
• Strong understanding of networking fundamentals (segmentation, firewalls, proxies, routing) and how to apply compensating controls.
• Cloud security controls experience in Azure and/or AWS (IAM, network controls, logging, security services).
• Proficiency in scripting/automation (Power Shell and/or Python); familiarity with infrastructure as code (e.g., Terraform) preferred.
• Ability to translate risk into technical control requirements and document controls for audit and compliance purposes.
• Excellent written and verbal communication; ability to work across infrastructure, application, and governance teams.

• Experience with configuration management and compliance platforms (e.g., Intune, Group Policy, SCCM/MECM, Ansible, Chef, Puppet).
• Experience with vulnerability scanning and exposure management tools (e.g., Tenable, Qualys, Rapid7) and mitigation engineering workflows.
• Experience tuning EDR policies and implementing detection/response guardrails (e.g., Microsoft Defender for Endpoint, Sentinel One, Crowd Strike).
• Experience with SIEM/SOAR integration…
