Freelance Probabilistic Risk Analysis Engineer Jobs in Virginia

ZERMOUNT POSITION DESCRIPTION (PD) SECURITY & RISK ENGINEER (SRE)

POSITION OVERVIEW

Zermount Inc. is seeking a System Risk Engineer (SRE) to support system risk analysis and ensure that federal information systems comply with Information Assurance and cybersecurity standards. The SRE exists to ensure organizational systems are secure, resilient, and defensible in real-world operating conditions, not simply compliant with security documentation. This role directly contributes to mission assurance by identifying, validating, and reducing cybersecurity risk through direct technical assessment, control validation, and risk-based decision support across enterprise environments.

Operating at the intersection of security engineering, risk assessment, and compliance, the SRE transforms federal mandates (e.g., NIST RMF, FISMA, EO 14028, OMB directives) into measurable security outcomes by validating the effectiveness of security controls within live systems. The role requires continuous evaluation of system posture through hands-on analysis of architectures, configurations, logs, vulnerability data, and control implementations across cloud, network, operating system, application, and database layers.

This position demands foundational technical expertise across multiple domains, enabling the SRE to assess complex enterprise environments, identify exploitable conditions, and determine whether implemented security controls effectively reduce risk. The SRE is expected to go beyond documentation review and verify findings through system-level evidence, testing, and analysis, ensuring the findings reflect actual operational risk.

The SRE is a core enabler of Zermount's Modern GRC mindset, which emphasizes:

• Continuous, real-time risk identification during compliance assessments
• Risk prioritization based on exploitability, exposure, and mission impact
• Direct integration with engineering and operations teams to drive remediation
• Elimination of "check-the-box" compliance in favor of validated security outcomes

You will be directly responsible for supporting system authorization and mission assurance by producing objective, defensible, and technically accurate findings that enable Authorizing Officials, ISSOs, and system owners to make informed risk decisions. This includes conducting security control assessments, validating Zero Trust implementation, analyzing architectural and configuration changes, and ensuring that remediation actions are both effective and sustainable to reduce risk.

DUTIES & RESPONSIBILITIES

General Duties

• Execute Security Assessments (SA), Risk Assessments (RA), and Ongoing Authorization (OA) activities by validating security controls in live environments, not solely through documentation review
• Conduct technical verification and validation of security controls across operating systems, applications, databases, cloud platforms, and network infrastructure
• Identify real-world security risks, including exploitable vulnerabilities, misconfigurations, weak trust boundaries, and control failures
• Perform continuous risk analysis using outputs from vulnerability scans, penetration testing, logging platforms, and configuration assessments
• Develop risk-based findings and POA&M matrices, prioritizing remediation based on exploitability, exposure, and mission impact
• Produce executive-quality artifacts (SARs, risk memos, ATO packages, executive briefings) with validated, evidence-backed findings
• Conduct impact analysis for Requests for Change (RFCs), identifying security implications of architectural, configuration, or system modifications
• Validate Zero Trust implementation and alignment across system architectures and capabilities
• Perform technical assessments of system architecture, data flows, and trust boundaries to identify control gaps
• Conduct compliance validation for TIC, FISMA, and federal cybersecurity mandates through technical inspection and testing
• Ensure all deliverables meet accuracy standards with zero rework required and are aligned to program and client expectations
• Provide weekly status reporting and briefings with clear articulation of risks, risk mitigation progress, and technical findings
