Together, these engineers will lead advanced security engineering and architecture efforts for MAJESTIC’s mission-critical systems, including those operating in distributed, low-bandwidth, intermittently connected, and operationally constrained mission scenarios.\nThe Enterprise ISSE will design, develop, implement, and validate security architectures for MAJESTIC’s core systems and enterprise environments, ensuring security controls are integrated throughout the full engineering lifecycle-from requirements and high-level architecture through deployment, sustainment, modernization, and ATO maintenance.\nThe Edge ISSE, leveraging the job functions described in ISSE_Edge, will engineer cybersecurity solutions tailored for MAJESTIC’s forward-deployed systems, remote nodes, and tactical-edge deployments. This includes designing architectures resilient to degraded communications, intermittent connectivity, and operational constraints while ensuring protection, monitoring, and defensive behaviors function reliably at the edge.\nBoth ISSEs will evaluate how mission and environmental conditions influence risk, threat exposure, data assurance, and defensive design to ensure resilient cybersecurity performance across MAJESTIC’s distributed system footprint-even in degraded or disconnected conditions.\nWorking closely with program leadership, system owners, developers, ISSMs/ISSOs, enterprise architects, and cybersecurity operations teams, the ISSEs will align enterprise and edge architectures with federal security requirements-including NIST 800-53, RMF, ICD 503, and DAAPM-and ensure secure, real-time system operation throughout MAJESTIC’s mission landscape.\nThis role requires on-site supportin Springfield, VA.\nKey Responsibilities:\nDesign and engineer secure edge system architectures optimized for distributed, low-bandwidth, and intermittently connected environments. \nTranslate mission-specific security requirements into edge-focused technical specifications, models, and design artifacts. \nSelect, implement, and validate security controls and mitigations tailored to tactical edge systems, remote nodes, and constrained operating conditions. \nIntegrate security into edge data flows, system diagrams, and high-/low-level designs, ensuring resilience under degraded or disconnected scenarios. \nEngineer core security capabilities-including boundary protections, encryption, IAM, auditing, and secure configurations-adapted for edge deployments. \nEmbed security across the entire edge system lifecycle, from requirements through field deployment, sustainment, and modernization. \nDevelop and maintain A&A engineering documentation, supporting ATO evidence for edge systems governed by RMF, ICD 503, and DAAPM. \nTest and validate security control effectiveness across edge applications, platforms, networks, sensors, and compute nodes. \nPerform edge-specific risk assessments, threat modeling, and vulnerability analysis; recommend mitigations suitable for forward-operating environments. \nEvaluate the security implications of system changes, upgrades, integrations, and technology refreshes affecting edge nodes and data paths. \nApply DISA STIGs, CIS Benchmarks, and maintain hardened configuration baselines designed for edge hardware and software. \nDesign monitoring architectures enabling SIEM connectivity, detection rules, audit/log collection, and event correlation-even across intermittent or delayed data links. \nSupport incident response by providing edge-architecture forensics, impact assessments, and mission-sustaining remediation guidance. \nCollaborate with developers, integrators, system administrators, and cyber teams to ensure secure deployment and integration of edge systems across MAJESTIC. \nPresent findings and recommendations on edge security engineering risks, architectures, and resilience strategies to senior leadership. \nProduce edge-focused technical documentation, diagrams, reports, SOPs, and design artifacts that support mission operations and accreditation. \n Education:\nHigh School diploma or equivalent \nCertifications (CWF Requirements):\nCandidates must satisfy Cybersecurity Workforce Framework (CWF) ID 652 (Security Architect, Intermediate Level) or 633 (System Security Engineer, Intermediate Level) requirements, as outlined by Navy COOL.This requirement can be met by possessing one or more of the following qualifyingcertifications:\n\nCertified Cloud Security Professional (CCSP). \nCertified Information Systems Security Officer (C)ISSO-A). \nCertified Secure Software Lifecycle Professional (CSSLP). \nCompTIA Cloud+. \nCompTIA SecurityX (formerly CASP+).\nFederal IT Security Professional-Designer-NG (FITSP-D). \nGIAC Cloud Security Automation (GCSA). \nGIAC Continuous Monitoring Certification (GMON). \nGIAC Security Essentials Certification (GSEC). \nOR This requirement can be met through:\nABachelor’s Degree in Cybersecurity, Computer Science, IT, or a related field. \nExperience:\n2-5 years of professional experience managing and supporting enterprise-levelITenvironments.\nTechnical Skills:\nStrong understanding of edge security architecture, secure system design, and engineering principles for distributed and intermittently connected environments. \nExperience developing SSPs, security diagrams, interface documentation, and control implementation descriptions for edge-deployed systems. \nProficiency with vulnerability scanning tools (Nessus, ACAS, Qualys) and analysis platforms, including assessment of remote nodes and field-deployed assets. \nKnowledge of DISA STIGs, CIS Benchmarks, and secure configuration/hardening standards, applied to resource-constrained edge hardware and software. \nFamiliarity with SIEM platforms (Splunk, SolarWinds) and mission-edge monitoring architectures, including delayed, disconnected, or low-bandwidth event collection. \nUnderstanding of Windows Server, Active Directory security, RHEL, and core network security concepts (TCP/IP, VLANs, IPsec, firewalls), including their application in distributed, tactical networks. \nExperience conducting edge-focused risk assessments, threat modeling, and architecture-level recommendations that account for operational constraints and mission scenarios. \nHigh-quality technical writing and documentation skills for engineering artifacts, audit evidence, and mission-specific edge system documentation. \nClearance Requirement:\nActiveTS/SCI clearance with the ability to obtain and maintain aTS/SCI with CI Poly. \nWork Environment and Notes:\nOn-Site Work: All work must be conductedon-site in Springfield, VA. \nProgram Scope: Supports on-premises enterprise IT environments, including virtualized Windows servers, MS SQL Server databases, and networking layers. \n Subcontractor Role: Responsibilities and compensation vary based on the subcontract agreement, with a competitive salary aligned to market rates and role-specific requirements.","description_format":"text","description_chars":7146,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":2,"team_size_min":null,"manages_managers":false,"education":{"level":"high_school","optional":true},"security_clearance":true,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United
