Following the initial screens, you will move to the formal interview stage. This is often a highly structured panel interview conducted either virtually or physically on-site at an HII facility. The panel is typically comprised of the hiring program manager and several senior members of the security engineering team. Each panelist will ask specific, pre-determined questions covering a diverse range of categories, from deep technical engineering concepts to behavioral and personality-related scenarios.

This visual timeline outlines the typical progression from your initial contact with HR to the final decision. Candidates should use this timeline to pace their preparation, ensuring they are ready for the distinct format of both the automated video screen and the highly structured, multi-person panel interview.

To succeed in the HII interview process, you must perform well across several distinct evaluation areas. The panel of interviewers will assess your depth of knowledge in these specific domains to ensure you can handle the responsibilities of a Security Engineer.

Defense-in-Depth & Compliance Frameworks

This area evaluates your ability to design and maintain secure systems that comply with strict federal mandates. HII operates under continuous scrutiny from government auditors, making compliance a foundational engineering requirement.

Be ready to go over:

• NIST Guidelines – Deep familiarity with NIST SP 800-53 and NIST SP 800-171 controls.

As a Security Engineer at HII, your day-to-day activities will be diverse and deeply integrated into the company's broader engineering and manufacturing operations. You will not operate in a silo; instead, you will serve as a trusted security advisor across multiple programs.

Your primary responsibility is to design, implement, and maintain robust security controls across HII networks, systems, and platforms. This involves conducting continuous risk assessments, analyzing system architectures for security weaknesses, and defining security requirements for new technology acquisitions. You will play an active role in ensuring that all systems maintain their authorization to operate (ATO) by keeping them aligned with federal cybersecurity frameworks.

Collaboration is a core component of this role. You will work alongside systems engineers, software developers, network administrators, and physical security teams to ensure a unified approach to security. For example, when a new system is designed for a naval vessel or a defense program, you will collaborate with the design team to threat-model the architecture, identify potential attack vectors, and embed security controls directly into the system's foundation. Additionally, you will assist in responding to security alerts, conducting forensic analyses, and preparing detailed technical reports for senior leadership and government stakeholders.
