Core Security Engineering and Architecture

As a Security Engineer, you must possess a rock-solid foundation in network security, system hardening, and threat mitigation. Interviewers evaluate your ability to design secure systems and identify flaws in existing architectures. A strong candidate will naturally balance security requirements with the need for operational uptime—a critical consideration in the utility sector.

Be ready to go over:

• Network security – Firewalls, IDS/IPS, segmentation, and zero-trust principles.
• Incident response – The lifecycle of an alert, from detection and triage to containment and eradication.
• Risk assessment – How to evaluate vulnerabilities based on exploitability and business impact.
• Advanced concepts (less common) –
  • OT/ICS security principles (e.g., Purdue Model).
  • NERC CIP compliance standards.
  • Cloud security architecture (AWS/Azure).

Example questions or scenarios:

• "If you see an alert for unexpected outbound traffic from a critical internal server, what are your first three steps?"
• "How would you design a secure network boundary between a corporate IT environment and an industrial control system network?"
• "Explain the difference between a vulnerability assessment and a penetration test, and when you would use each."

Behavioral and Team Collaboration

Working at Duke Energy requires a high degree of collaboration. You will often need to enforce security policies with teams whose primary goal is keeping systems running without interruption. Interviewers are looking for empathy, clear communication, and a team-oriented mindset.

Be ready to go over:

• Conflict resolution – Navigating disagreements over security policies or patching schedules.
• Communication – Explaining complex security risks to non-technical stakeholders.
• Adaptability – Handling shifting priorities during a live incident.

Example questions or scenarios:

• "Describe a time when you had to enforce a security policy that was highly unpopular with the end-users. How did you handle it?"
• "Tell me about a time you had to work with a difficult team member to resolve a critical issue."
• "How do you prioritize your tasks when you receive multiple high-severity alerts at the same time?"

Key Responsibilities

As a Security Engineer at Duke Energy, your day-to-day work revolves around proactive defense and continuous monitoring. You will be responsible for deploying, configuring, and tuning security tools that protect our enterprise and operational networks. This includes analyzing threat intelligence, managing vulnerabilities, and ensuring that our infrastructure meets strict regulatory compliance standards.

Collaboration is a massive part of this role. You will frequently partner with infrastructure engineers, application developers, and operational technology teams to integrate security controls without disrupting critical grid operations. When an incident occurs, you will act as a key technical responder, analyzing logs, containing threats, and developing remediation strategies.

You will also drive continuous improvement initiatives. This might involve automating repetitive security tasks, refining incident response playbooks, or leading security architecture reviews for new business projects. Your ultimate deliverable is a resilient environment that can withstand modern cyber threats while supporting the company's mission to deliver reliable energy.

Role Requirements & Qualifications

To be competitive for the Security Engineer position, you need a solid mix of technical acumen and the right soft skills to navigate a large, regulated enterprise.

• Must-have skills – Strong foundational knowledge of networking protocols (TCP/IP, DNS, HTTP), experience with enterprise security tools (SIEM, EDR, firewalls), and a clear understanding of vulnerability management and risk assessment. You must also have excellent analytical skills to triage alerts and investigate anomalies.
• Experience level – Typically, candidates have 3 to 5+ years of dedicated experience in cybersecurity, network engineering, or systems administration with a heavy security focus. A background in enterprise IT environments is essential.
• Soft skills – Exceptional verbal and written communication skills are required. You must be able to translate technical risks into business impacts and build consensus across disparate teams.
• Nice-to-have skills – Experience with Operational Technology (OT) or Industrial Control Systems (ICS) security is a massive differentiator. Familiarity with NERC CIP regulations, cloud security platforms, and scripting languages (Python, PowerShell) for automation will also make your profile stand out.

Frequently Asked Questions

Q: How difficult is the interview process? The difficulty is generally rated as average. The panel is not trying to trick you with obscure brainteasers; rather, they are focused on having a practical, thorough conversation about your actual experience and how it applies to our environment.

Q: What is the culture like during the interview? Candidates consistently report a relaxed, polite, and welcoming atmosphere. The panel wants to get to know you as a potential colleague. Expect a collaborative tone where back-and-forth dialogue is highly encouraged.

Q: Why do interviews start with a "safety advisory"? At Duke Energy, safety is foundational to our culture. It is standard practice to begin meetings with a brief "safety moment"—a short tip or reminder about physical or cybersecurity safety. It sets the tone for our operational priorities.

Q: How long does the process take from interview to offer? Timelines can vary. While the interview itself is often a single comprehensive panel round, the time to receive an offer can range from a few days to a few weeks, occasionally impacted by broader corporate hiring cycles or pauses.

Q: Do I need prior experience in the energy sector to be hired? No, prior energy or utility experience is not strictly required. While knowledge of OT/ICS environments is a great bonus, strong foundational IT security skills and a willingness to learn the nuances of critical infrastructure are what matter most.

Other General Tips

• Prepare your own Safety Moment: Because you know the interview will likely start with a safety advisory, preparing a brief, relevant safety tip (e.g., a quick reminder about MFA, or a physical safety tip like ergonomics) shows incredible cultural alignment and preparation.
• Know your resume flawlessly: The panel will use your resume as the primary roadmap for the interview. Be prepared to discuss the technical details, business impact, and your specific role for every single bullet point.
• Engage the entire panel: You will be speaking with 3 to 4 people. Make sure to make eye contact (even virtually) and direct your answers to the whole group, not just the person who asked the question.
• Ask thoughtful questions: When given the chance to ask questions at the end, use it to show your interest in the company's specific challenges. Ask about the integration of IT and OT, or how the team measures success.
• Emphasize availability alongside security: In the utility sector, bringing a system down for patching can be just as impactful as a cyber attack. Show that you understand how to balance security controls with operational uptime.
