Endpoint Security Engineer Jobs in Arkansas (NOW HIRING)

• Demonstrated experience designing, building, and operating security platforms (SIEM, EDR, IAM, CSPM) in production environments.
• Proven track record of building automation, integrations, or tooling that measurably reduced manual security work.
• Design, build, and maintain core security platforms — SIEM, EDR, IAM, and CSPM — including data pipelines, ingestion design, and platform integrations.
• Own the SIEM logging and detection data pipeline; design ingestion, parsing, and enrichment to support detection engineering and incident response.
• Build incident response tooling, forensic capabilities, and response automation to accelerate detection and response.
• Design and implement vulnerability scanning architecture and integrate vulnerability management into CI/CD pipelines.
• Build cloud security guardrails, infrastructure-as-code (IaC) security controls, and CSPM integrations across AWS, Azure, and/or GCP.
• Engineer the enterprise IAM platform, including identity federation, SSO, and automated provisioning/de-provisioning workflows.
• Architect and harden network and endpoint security controls (NGFW, EDR, segmentation) and evaluate emerging technologies.
• Build threat intelligence platform integrations and enrichment pipelines to support detection and response teams.
• Implement technical controls that satisfy compliance framework requirements (C2M2, NIST CSF, TSA Security Directives) in partnership with GRC.
• Provide technical evidence and configuration exports to support C2M2, NIST CSF, and TSA Security Directive audits and assessments.
• Support control testing by producing log samples, access reports, and system configuration artifacts requested by GRC/auditors.
• Document technical risk exceptions and compensating controls when a system can't fully meet a framework requirement.
• Maintain a mapping between deployed security tooling/controls and the specific framework requirements they satisfy.
• Design and deliver security platforms and integrations in alignment with enterprise reference architectures set by the Information Security Architect.
• Partner with engineering, platform, and product teams to embed secure design practices into the software delivery lifecycle.
• Serve as a technical mentor across the security organization; set and document engineering standards and best practices.
• Evaluate new security tools and technologies; drive build-vs-buy recommendations and proof-of-concept efforts.
• Participate in a shared on-call rotation to support critical security infrastructure and respond to platform-impacting issues.

• Bachelor’s degree in computer science, Engineering, Information Security, or a related field is required. Master's degree is preferred.
• 5–10+ years of progressive experience in security engineering or systems engineering.
• Professional certifications preferred: CISSP, GCIH, OSCP, AWS Certified Security – Specialty, Microsoft Certified: Azure Security Engineer, or Certified Kubernetes Security Specialist (CKS).

• Hands-on expertise in operating and tuning SIEM platforms (e.g., Splunk, Microsoft Sentinel), including correlation rule and detection content development.
• Working knowledge of cloud security engineering across AWS, Azure, and/or GCP, including IaC security controls and CSPM tooling.
• Experience engineering identity and access management (IAM) platforms, federation/SSO, and privileged access management (PAM).
• Solid understanding of network and endpoint security technologies, including NGFW, EDR, and network segmentation.
• Experience integrating vulnerability management and security testing into CI/CD pipelines.
• Familiarity with threat intelligence platforms and enrichment pipeline design.
• Working knowledge of compliance frameworks (C2M2, NIST CSF, TSA Security Directives) and the ability to translate requirements into technical controls.
• Ability to evaluate tooling trade-offs, design integrations, and reason about scale, reliability, and operational impact.
• Strong communication skills; able to explain complex technical designs to both technical and non-technical audiences.
• Self-directed; able to drive multi-quarter engineering road maps with minimal supervision.
• Meticulous attention to detail when building, testing, and documenting security platforms and automation.
