Shain Associates

Job Description

  • Continue advancements in the firm’s Linux security strategy by creating resilient controls across enterprise infrastructure
  • Lead adversary-informed assessments of Linux systems to stay ahead of emerging risks to critical business platforms
  • Design hardened Linux build standards that reduce attack surface while supporting reliable, high-performance technology operations
  • Develop automated checks and remediation workflows that continuously validate configuration, access, and patching practices at scale
  • Partner with security operations and infrastructure teams to investigate Linux-focused threats and strengthen detection and response playbooks
  • Analyze privilege paths, authentication flows, and service configurations to identify opportunities for containment and least-privilege enforcement
  • Advise engineering teams on secure deployment patterns for Linux workloads across data center and cloud-based environments
  • Create practical security guidance, threat models, and technical documentation that help teams make informed infrastructure decisions
  • Stay ahead of evolving threats to Linux environments by translating threat intelligence into proactive hardening priorities

What’s required

  • Five or more years of hands-on experience securing and engineering enterprise Linux environments in complex production settings
  • Strong offensive security or red-team background, including hands-on exploitation, attack-path analysis, and adversary simulation against Linux systems
  • Deep knowledge of Linux hardening, privilege management, authentication, access controls, logging, and secure configuration practices
  • Experience performing vulnerability validation, penetration testing, threat modeling, and remediation planning for Linux infrastructure
  • Proficiency with scripting or automation to assess configurations, enforce baselines, and support repeatable security operations
  • Ability to analyze system logs, process behavior, network activity, and endpoint telemetry during security investigations
  • Understanding of container, virtualization, and cloud-based Linux security considerations in enterprise environments
  • Strong communication and collaboration skills, with the ability to influence infrastructure, security, and engineering stakeholders
