About The Position

M9 Solutions is seeking an ISSE to work on-site in support of a government contract for a client located in Bellevue, Nebraska. An active Top Secret security clearance is required. The role applies systems security engineering and cybersecurity practices across the system life cycle, translating mission objectives, operational needs, threats, and policy into measurable security requirements and engineering specifications. It supports technical reviews and evaluates systems for security, resilience, reliability, maintainability, interoperability, scalability, and operational supportability.

The position develops or reviews security architecture and engineering products, defines security architecture patterns, and designs or recommends safeguards for protecting data. It also conducts or supports threat modeling, attack-surface analysis, misuse-case development, and engineering risk assessments. The posting lists a salary range of $90,000–$105,000 USD and describes the role as a full-time employee position.

Requirements

• Active Top Secret security clearance.
• Bachelor’s degree or equivalent experience.
• At least 5 years of cybersecurity engineering, information assurance, or security architecture experience.
• ITIL Foundations v4 certification or ability to obtain it within 9 months.
• Certifications such as CISSP, GIAC, CEH, or equivalent advanced cybersecurity credentials.
• Strong technical background in system security, network security, cryptography, secure architectures, firewalls, and DevSecOps environments.
• Proficiency in programming languages such as Java, C++, and Python, with hands-on experience in secure coding and automation.
• Familiarity with cloud security (AWS, Azure, or GCP), virtualization, identity management, and security compliance frameworks.
• Demonstrated strength in problem solving, communication, documentation, and attention to detail.
• Experience designing secure architectures for enterprise systems, applications, and cloud platforms.

Nice To Haves

• Knowledge of systems engineering life-cycle processes, including requirements decomposition, functional analysis, design synthesis, integration, verification, validation, and configuration management.
• Experience with systems engineering and systems security engineering practices.
• Ability to develop and analyze system, subsystem, interface, and security requirements.
• Knowledge of security architecture principles, including defense in depth, Zero Trust architecture, ICAM, network segmentation and boundary protection, key management, secure configuration, and system hardening.
• Experience with model-based systems engineering tools or methods, such as SysML, UML, architecture modeling, or digital engineering environments.
• Experience with enterprise architecture frameworks or federal architecture approaches.
• Experience with risk management and security engineering standards, such as NIST risk management and security-control frameworks.
• Experience with cyber forensics, intrusion detection, threat analysis, and incident response.
• Strong background in system and network security, encryption algorithms, cryptography, identity management, and secure architectures.
• Proficiency with tools such as Splunk, Nessus, Wireshark, Nmap, AWS/Azure/GCP security suites, and vulnerability management platforms.
• Knowledge of secure programming in Java, C++, and Python, and automation for security workflows.
• Ability to communicate complex technical architecture and cybersecurity issues to engineers, program managers, system owners, and senior leaders.
• Ability to develop clear technical documentation, diagrams, briefings, decision papers, and engineering recommendations.
• Ability to work effectively across engineering, cybersecurity, operations, acquisition, testing, and sustainment organizations.
• Ability to manage competing priorities while maintaining technical rigor, traceability, and configuration discipline.
• Familiarity with DevSecOps practices, virtualized environments, cloud security frameworks, and infrastructure-as-code such as Terraform.
• Certifications such as CISSP, CISSP-ISSEP, CISSP-ISSAP, INCOSE ASEP, GIAC, CEH, or equivalent advanced cybersecurity credentials.
• Strong communication, documentation, analytical skills, and attention to detail.

Responsibilities

• Translate mission objectives, operational needs, threats, and policy requirements into measurable system security requirements and engineering specifications.
• Participate in systems engineering technical reviews, including requirements, preliminary design, solution design document, test readiness, and operational readiness reviews.
• Integrate cybersecurity requirements throughout the system life cycle, from concept development and requirements analysis through deployment, sustainment, and disposal.
• Evaluate system designs for security, resilience, reliability, maintainability, interoperability, scalability, and operational supportability.
• Develop or review system architecture products, including operational views, logical and physical architecture diagrams, data-flow diagrams, trust-boundary and network diagrams, interface control documents, and deployment diagrams.
• Develop and maintain cybersecurity artifacts, including system security plans, security-control implementation statements, architecture diagrams, risk assessments, remediation plans, contingency plans, and security test documentation.
• Define security architecture patterns for identity and access management, privileged access, encryption, key management, network segmentation, endpoint protection, logging, monitoring, backup, recovery, and remote access.
• Design or recommend technical safeguards that protect data in transit, at rest, and in use, consistent with mission and system requirements.
• Conduct or support threat modeling, attack-surface analysis, misuse-case development, and engineering risk assessments.
