Cyber Security Engineer

Cybersecurity Engineer

The Cybersecurity Engineer will support system-level security initiatives across multiple Navy Submarine subsystems, focusing on securing Linux-based platforms, containerized environments, and emerging cloud-like architectures. This role suits an engineer who enjoys solving complex, cross-domain problems, working across decentralized systems, and driving security improvements from initial concept through detailed design and implementation. The position offers significant exposure to Red Hat-based Linux security, container security, and enterprise security frameworks, with the opportunity to influence security practices across a broad engineering organization.

Responsibilities

• Drive system-level cybersecurity initiatives across multiple Navy Submarine subsystems from analysis through design and implementation.
• Translate high-level security requirements and frameworks (such as NIST 800-53) into clear, actionable guidance for engineering and development teams.
• Develop, document, and implement security best practices across multiple subsystems and platforms.
• Assess existing subsystem architectures to identify security gaps and recommend improvements and hardening strategies.
• Coordinate with multiple engineering teams to standardize and implement security solutions in a consistent and scalable manner.
• Lead cross-functional security efforts, influencing technical direction and aligning teams around security objectives and priorities.
• Configure, harden, and secure Red Hat-based Linux systems, including RHEL, CentOS, and Fedora environments.
• Implement and tune security tools and controls such as SELinux, USBGuard, firewalld, and related Linux security mechanisms.
• Secure containerized environments using technologies such as Podman, Docker, and Kubernetes, including configuration and policy enforcement.
• Contribute to the design and security of on-premises or cloud-like infrastructures, including PKI and secure communications between systems.
• Develop custom security solutions, scripts, and lightweight tools primarily in Python, with some C/C++ to enforce, automate, and monitor security controls.
• Design solutions for unique or niche security requirements that arise from specialized system constraints or mission needs.
• Continuously monitor, assess, and respond to evolving threats, including newly discovered vulnerabilities and zero-day exploits.
• Stay current with emerging risks, security advisories, and industry best practices, and proactively propose mitigation strategies.
• Collaborate in ambiguous and complex technical environments, using strong problem-solving skills to resolve security challenges across decentralized systems.

Essential Skills

• Approximately 510+ years of experience in cybersecurity, systems engineering, or Linux administration.
• Strong understanding of Linux operating systems, particularly Red Hat-based environments such as RHEL, CentOS, and Fedora.
• Hands-on experience configuring and securing Linux systems using tools such as SELinux, USBGuard, and firewalld.
• Experience working with security frameworks and compliance standards, including interpreting and applying NIST 800-53 controls.
• Ability to translate high-level security requirements into practical, implementable technical guidance for engineering teams.
• Proven experience working across multiple teams and influencing technical direction in a collaborative environment.
• Strong problem-solving mindset with the ability to operate effectively in ambiguous and complex technical settings.
• Security+ certification or the ability to obtain it within a defined timeframe.

Additional Skills & Qualifications

• Experience with container technologies such as Kubernetes, Podman, and Docker, including security configuration and hardening.
• Exposure to cloud or cloud-like architectures, including on-premises or hybrid environments with shared or distributed services.
• Scripting and programming experience, especially in Python, with additional experience in C or C++.
• Familiarity with Rust as a nice-to-have programming skill for security tooling or systems development.
• Understanding of Public Key Infrastructure (PKI), digital certificates, and secure system-to-system communication mechanisms.
• Familiarity with Model-Based Systems Engineering (MBSE) concepts and artifacts as a nice-to-have capability.
• Experience with file sharing and security protocols, including hardening of NFS or similar technologies.
• Strong communication skills to clearly convey security requirements, risks, and recommendations to technical and non-technical stakeholders.

Work Environment

The role centers on securing complex, mission-critical systems that run on Linux operating systems in Red Hat-based environments. You will work extensively with tools such as SELinux, USBGuard, firewalld, and related Linux security utilities, and you will engage with container platforms including Podman, Docker, and Kubernetes. The environment includes on-premises or cloud-like infrastructures that rely on PKI, secure communications, and hardened file sharing protocols such as NFS. Work is highly collaborative, involving close interaction with multiple engineering teams and disciplines in a structured, security-focused setting. The position emphasizes continuous learning and staying current with emerging vulnerabilities and threats, and it offers the opportunity to shape enterprise-wide security practices while working on sophisticated naval systems.
