Note that depending on the specific federal project or clearance requirements tied to the Annapolis Junction office, additional screening steps may be introduced.

Cybersecurity Compliance & Frameworks

Understanding regulatory standards is the backbone of the Security Engineer role at Bigbear. Because we operate heavily within defense and government sectors, your ability to translate compliance requirements into actionable engineering tasks is critical. Interviewers evaluate this by discussing your hands-on experience with federal frameworks and your ability to navigate audits. Strong performance means you don't just know the acronyms; you know how to implement the controls practically without paralyzing the engineering team.

Be ready to go over:

• NIST 800-53 & RMF – Understanding the Risk Management Framework lifecycle and how to select, implement, and assess security controls.
• Continuous Monitoring – How you maintain compliance post-deployment and automate evidence collection.
• Audit Preparation – Your experience acting as a liaison between technical teams and external auditors or government assessors.
• Advanced concepts (less common) – FedRAMP authorization processes, DoD SRG compliance, and integrating compliance-as-code into CI/CD pipelines.

Example questions or scenarios:

• "Walk me through how you would conduct an initial risk assessment for a newly developed AI analytics platform."
• "Describe a time you had to enforce a strict NIST control that significantly impacted the development team's workflow. How did you handle it?"
• "How do you ensure continuous compliance in a cloud environment where infrastructure is constantly changing?"

Risk Assessment & Vulnerability Management

Identifying vulnerabilities is only half the job; prioritizing and mitigating them is where a Security Engineer truly adds value. Interviewers want to see your methodology for triaging security findings from various tools and translating them into actionable remediation plans. A strong candidate will demonstrate a risk-based approach, showing that they understand the difference between a theoretical vulnerability and a practical threat to Bigbear's specific environment.

Be ready to go over:

• Vulnerability Scanning – Experience with industry-standard tools (e.g., Nessus, Qualys) and how to interpret their output.
• Risk Scoring – How you use CVSS scores combined with environmental context to prioritize patching.
• Remediation Tracking – Managing Plans of Action and Milestones (POA&Ms) and driving them to closure.
• Advanced concepts (less common) – Threat modeling complex system architectures and conducting tabletop incident response exercises.

Example questions or scenarios:

• "If a critical zero-day vulnerability is announced, walk me through your immediate next steps to assess our exposure."
• "How do you handle a situation where a system owner refuses to patch a critical vulnerability due to uptime concerns?"
• "Explain your process for translating a technical vulnerability report into a business risk summary for executive leadership."

Security Architecture & Cloud Defense

While compliance is a major focus, you must also possess the technical engineering chops to validate that security architectures are sound. Bigbear leverages modern cloud infrastructure to deliver its AI solutions. Interviewers will assess your understanding of secure network design, identity management, and cloud-native security controls. Success in this area requires proving you can look at a system diagram and immediately spot the weak links.

Be ready to go over:

• Cloud Security Basics – Securing AWS or Azure environments, managing IAM policies, and configuring security groups.
• Network Security – Understanding firewalls, VPNs, segmentation, and zero-trust principles.
• Data Protection – Encryption standards at rest and in transit, and secure key management practices.
