Candidates who successfully navigate the initial screening phase advance to a comprehensive panel interview involving multiple team members and engineering managers. This multi-person stage allows you to interact directly with peers and leaders who understand the day-id-day demands of the role. Approach this stage prepared to discuss both your technical capabilities and your ideal workplace environment, keeping in mind that the organization values structured, professional interactions and strong cultural alignment.

Technical Competence & Security Fundamentals

This evaluation area assesses your core understanding of network security, system hardening, and vulnerability management. Interviewers look for your ability to apply security principles to both corporate IT and industrial control systems. Strong candidates demonstrate practical familiarity with configuration standards, risk frameworks, and security tools.

Be ready to go over:

• Network security controls – Firewalls, access control lists, authentication mechanisms, and logging practices.
• Vulnerability assessment and penetration testing – Methods for identifying system weaknesses and conducting secure evaluations.
• Compliance frameworks – Familiarity with the NIST Cybersecurity Framework and Risk Management Framework.
• Advanced concepts (less common) – Specific OT/ICS protocols, eMASS artifact management, and customized threat modeling for industrial environments.

Example questions or scenarios:

• Describe your experience with vulnerability assessments on IT or operational networks.
• How would you approach securing a programmable logic controller against unauthorized access?
• What steps do you take when performing post-event analysis of an unusual network occurrence?

As a Security Engineer, your day-to-day work centers on securing critical infrastructure and industrial control systems against sophisticated cyber threats. You will actively assist with network penetration testing, web application security evaluations, and comprehensive cybersecurity vulnerability assessments. Your responsibilities include designing secure system architectures, implementing technical controls, and ensuring adherence to established government and industry compliance frameworks.

You will routinely collaborate with adjacent engineering teams, project managers, and external client stakeholders to integrate security measures seamlessly into ongoing projects. This involves hands-on implementation and hardening of servers, workstations, network switches, and programmable logic controllers. Additionally, you will draft critical technical artifacts, such as control listings, dataflow diagrams, and compliance documentation, ensuring that every project maintains the highest standard of confidentiality and integrity.

Meeting the qualifications for this role requires a solid foundation in computer science, cybersecurity, or related engineering disciplines, paired with a practical understanding of industrial security. Burns & McDonnell seeks candidates who combine technical capability with the adaptability needed to operate in diverse on-site corporate and industrial environments.

• Must-have skills – A Bachelor’s degree in Cybersecurity, Computer Science, Computer Engineering, or Electrical Engineering (or equivalent experience); a fundamental understanding of cybersecurity principles and control systems; familiarity with vulnerability assessments and penetration testing; and effective written and oral communication skills.
• Nice-to-have skills – Prior internship experience in industrial cybersecurity; active industry-recognized certifications such as ethical hacking or network engineering credentials; and familiarity with government accreditation systems like eMASS.
• Soft skills – Strong critical thinking, the ability to operate under tight project deadlines, and a proven capacity to collaborate within multidisciplinary consulting and engineering teams.

Q: How difficult is the interview process at Burns & McDonnell? While technical requirements are rigorous, candidates often note that the primary challenge lies in adapting to the structured video screening format. Preparing thoughtful, concise answers in advance will help you navigate the recorded video stage with confidence.

Q: What is the typical timeline from initial application to an offer? Recruiters typically reach out within about a week of application submission. The complete process moves efficiently through video screenings and panel interviews, usually concluding within a few weeks depending on team scheduling.

Q: Are remote work options available for this role? Work arrangements depend heavily on specific project requirements, client locations, and team assignments, with many roles involving a hybrid balance of office, remote, and on-site industrial visits.

Q: What differentiates successful candidates during the panel interviews? Successful candidates demonstrate a genuine passion for critical infrastructure protection, clear communication skills, and an authentic alignment with the company’s collaborative and integrity-driven culture.

Q: How should I prepare for the asynchronous video interview? Treat the recorded video session as a live conversation by maintaining good eye contact with your camera, structuring your answers clearly, and practicing responses to standard behavioral prompts beforehand.

• Familiarize yourself with frameworks: Brush up on your working knowledge of the NIST Cybersecurity Framework and Risk Management Framework, as these guide much of the consulting practice's methodology.
• Practice structured storytelling: When answering behavioral or situational questions, use a clear framework to highlight your problem-solving process, actions taken, and the ultimate business impact.
• Be comfortable with video formats: Because the initial interview stage involves recording responses independently, practice talking to a camera without an interviewer present to build your comfort level.
• Highlight industrial awareness: If you have experience with Operational Technology or industrial control systems, make sure to spotlight it prominently to align with the core mission of critical infrastructure protection.
• Showcase your collaborative spirit: Emphasize your ability to work across different engineering disciplines and communicate technical risks clearly to non-technical stakeholders.
