About The Position

The Information System Security Engineer (ISSE) is a customer-facing cybersecurity engineering consultant supporting organizational ISSMs, ISSOs, Mission Partners, system owners, architects, and development teams. The role provides security architecture and Risk Management Framework (RMF) guidance for on-premises, cloud-hosted, legacy, and modernizing systems throughout the System Development Lifecycle (SDLC). The ISSE helps customers understand cybersecurity requirements and develop actionable technical solutions to implement controls, remediate vulnerabilities, and improve system security before or after formal assessment.

The role supports multiple concurrent systems, projects, and development efforts, translating governance requirements into threat-informed engineering solutions. The position follows a hybrid onsite schedule, with four days onsite weekly, and requires residence within commuting distance of Fort Meade, Maryland, or Chambersburg, Pennsylvania.

• Expert-level knowledge of RMF and NIST SP 800-37.
• Expert-level knowledge of NIST SP 800-53 security and privacy controls.
• Strong security architecture and systems-security engineering experience.
• Practical experience applying DoD STIGs, SRGs, and PPSM requirements.
• Experience converting compliance requirements into practical engineering solutions.
• Hands-on engineering or configuration experience with enterprise security technologies, including SIEM platforms such as Splunk or Elastic, vulnerability scanners such as ACAS/Nessus, and EDR technologies.
• Knowledge of traditional and cloud-native architectures.
• Ability to support multiple concurrent systems, projects, and development efforts.
• Strong written, verbal, consulting, and presentation skills.
• Must reside within commuting distance of Fort Meade, MD, or Chambersburg, PA, to work a hybrid schedule with four days onsite weekly.

Nice To Haves

Responsibilities

• Serve as the embedded security engineering expert for Mission Partners, ISSMs, ISSOs, system owners, architects, and development teams.
• Provide security engineering support throughout the SDLC, including requirements gathering, design reviews, sprint planning, modernization, implementation, and production.
• Translate RMF, NIST SP 800-53, DoD cybersecurity policy, and other governance requirements into actionable, threat-informed engineering solutions.
• Conduct security architecture and design reviews for new and existing systems.
• Analyze network and cloud-native architectures, applications, APIs, microservices, containers, serverless functions, interfaces, and data flows to identify security weaknesses.
• Collaborate with architects and developers to identify achievable security controls and reduce compliance friction before formal assessment.
• Engineer and document vulnerability mitigation strategies and provide technical consultation supporting POA&M corrective actions.
• Develop solutions that reduce system attack surface and improve resiliency without unnecessarily compromising mission capability.
• Translate security requirements into technical implementation activities such as MFA, database encryption, and secure network zoning.
• Apply DoD STIGs, SRGs, and PPSM guidance to system engineering activities.
• Use security telemetry and findings from SIEM, vulnerability scanning, and EDR technologies to recommend architectural and engineering improvements.
• Provide technical mentorship and guidance to ISSMs, ISSOs, developers, and system owners.
• Present cybersecurity risks, architectural findings, mitigation strategies, and recommendations to technical personnel and Government leadership.
• Document customer interactions, supported systems, issues addressed, and technical recommendations as required.

Benefits

• 26 days of paid leave, including vacation, sick, personal time, and holidays.
• Performance bonuses based on individual contributions and company-wide results.
