TS/SCI w/Poly

Position Overview

Position is with the VA Intel Customer and requires an active TS/SCI with Full Scope Poly clearance.

The ISSE will lead and execute security engineering activities across complex, enterprise‑scale environments. This role requires deep technical expertise across infrastructure, platforms, and applications, combined with expert‑level, hands‑on experience implementing the NIST Risk Management Framework (RMF) within federal government environments. The ideal candidate is a technical practitioner, not just an advisor – someone who can design, implement, assess, and secure systems end‑to‑end while directly supporting system authorization, continuous monitoring, and risk‑based decision‑making. This role also serves as the technical focal point for all security incidents, leading triage, investigation, and resolution efforts in coordination with program and enterprise security teams.

Qualifications

• Bachelor’s Degree in Computer Science, IT, or a related technical discipline, or the equivalent combination of education, technical training, or work/military experience
• Minimum ten (10) years of related cyber security engineering experience

Required Knowledge / Skills

• Proven hands‑on Cyber Security Engineer SME, not policy‑only or audit‑only
• Comfortable working across network, system, platform, and application layers
• Deep understanding of how security controls are actually implemented and validated
• Experience in federal RMF‑driven environments
• Able to bridge security, engineering, and compliance effectively
• Experienced in managing security incidents from detection through resolution
• Skilled at balancing immediate incident response needs with long‑term security improvements
• Effective collaborator across organizational boundaries during high‑pressure security events
• Operate independently as the technical authority for system security engineering
• Demonstrate the ability to provide technical hands‑on configuration, validation, and assessment of security controls
• Translate RMF and NIST requirements into real‑world technical implementations
• Communicate complex technical security issues clearly to both technical and non‑technical stakeholders
• Maintain a strong balance between security compliance and operational practicality
• Lead rapid response to security incidents with minimal guidance
• Demonstrate strong analytical and troubleshooting skills under pressure during active security events
• Effectively communicate incident status, impact, and remediation progress to technical and leadership audiences

Security & Compliance

• Expert‑level experience with NIST Risk Management Framework (RMF) in federal government environments
• Strong knowledge of:
  • NIST SP 800‑53
  • NIST SP 800‑37

• Direct involvement I ATO packages, control implementation, and assessments
• Hands‑on experience with Security Information and Event Management (SIEM) platforms (e.g., Splunk, ELK Stack, ArcSight, QRadar)
• Demonstrated experience in security incident detection, analysis, and response
• Proven ability to triage security alerts and determine criticality and impact

Infrastructure & Platforms (Hands‑On)

• Networking (e.g., routing, switching, firewalls, load balancers, network security controls)
• Operating Systems:
  • Windows Server

Engineering Experience

• Security engineering and system hardening
• Vulnerability discovery and remediation
• Secure system design and architecture reviews
• Technical documentation supporting RMF compliance
• Experience in cloud environments (AWS, Azure, GCP, CI) within federal RMF contexts

• Serve as technical point of contact for all security incidents affecting the program
• Lead triage and analysis of new security alerts from SIEM, IDS/IPS, and other security monitoring tools
• Drive remediation efforts for recurring security alerts, identifying root causes and implementing systemic fixes
• Coordinate incident response activities between program stakeholders and enterprise security operations
• Act as primary liaison between program teams and enterprise security for incident escalation, resolution, and reporting
• Perform forensic analysis and technical investigations of security events
• Document security incidents, response actions, and lessons learned
• Develop and maintain runbooks and playbooks for common security incident types
