Remote Security Control Assessor Jobs in Springfield, VA

ZERMOUNT POSITION DESCRIPTION (PD) SECURITY & RISK ENGINEER (SRE)POSITION OVERVIEWZermount 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 assessmentsRisk prioritization based on exploitability, exposure, and mission impactDirect integration with engineering and operations teams to drive remediationElimination of "check-the-box" compliance in favor of validated security outcomesYou 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 & RESPONSIBILITIESGeneral DutiesExecute Security Assessments (SA), Risk Assessments (RA), and Ongoing Authorization (OA) activities by validating security controls in live environments, not solely through documentation reviewConduct technical verification and validation of security controls across operating systems, applications, databases, cloud platforms, and network infrastructureIdentify real-world security risks, including exploitable vulnerabilities, misconfigurations, weak trust boundaries, and control failuresPerform continuous risk analysis using outputs from vulnerability scans, penetration testing, logging platforms, and configuration assessmentsDevelop risk-based findings and POA&M matrices, prioritizing remediation based on exploitability, exposure, and mission impactProduce executive-quality artifacts (SARs, risk memos, ATO packages, executive briefings) with validated, evidence-backed findingsConduct impact analysis for Requests for Change (RFCs), identifying security implications of architectural, configuration, or system modificationsValidate Zero Trust implementation and alignment across system architectures and capabilitiesPerform technical assessments of system architecture, data flows, and trust boundaries to identify control gapsConduct compliance validation for TIC, FISMA, and federal cybersecurity mandates through technical inspection and testingEnsure all deliverables meet accuracy standards with zero rework required and are aligned to program and client expectationsProvide weekly status reporting and briefings with clear articulation of risks, risk mitigation progress, and technical findingsSUBJECT MATTER EXPERTISE (SME)SME Area #1 -
