CARDS Graduate Advances from Intern to Cyber Security Systems Engineer

Not only do internships provide “real life” experience for Saint Leo University students, they also can lead to career opportunities and first jobs. Levi Leuck ’25 recently advanced from intern to full-time employee at Cole Engineering Services Inc. (CESI) in the Orlando, FL, area. 

Following the completion of his internship, Leuck was promoted to cyber security systems engineer, having secured the position prior to graduating on May 7 with a Bachelor of Science in cybersecurity.

The son of Donna Leuck, he was born in Russia and brought to the United States at an early age. He graduated from Bishop Moore Catholic High School in Orlando. 

“I chose Saint Leo’s Cybersecurity Program primarily because it was recognized by the National Security Agency [NSA] and the Department of Homeland Security [DHS] as a National Center of Academic Excellence (NCAE) in Cybersecurity,” he said.

“I actively sought out opportunities within the Tampa and Dade City communities to grow my cybersecurity skills, connect with professionals, and apply what I learned in real-world contexts,” Leuck added.

He cites Dr. Edward Santiago, assistant professor of computer science in the College of Computing, Artificial Intelligence, Robotics, and Data Science (CARDS), as a mentor. He was able to collaborate with Santiago on development of the college’s Cyber Lab, making it a space where “students could engage more deeply with their interests in computer science and cybersecurity, gaining essential hands-on experience that is often difficult to access in traditional classroom settings.” 

Leuck also helped Santiago to expand the PenTest Club, connecting students with professionals and employers from the Tampa and Dade City areas as well as the region. These included ConnectSecure, a software company in Tampa, and Sittadel, a computer security service in Lakeland, FL. Representatives of the companies spoke to Saint Leo students about securing cybersecurity employment and opportunities. 

“Additionally, we [Santiago and Leuck] partnered with the town of Saint Leo to host a cybersecurity community class focused on understanding current online threats and learning practical internet safety skills,” Leuck said. 

Santiago’s “unwavering dedication and the extraordinary work he continues to do for students” made a difference in Leuck’s academic journey. “His passion for teaching and mentorship sets him apart as a truly exceptional educator,” he said of Santiago. 

On the Job

As a cyber security systems engineer at CESI, Leuck plays a role in securing Department of Defense (DoD) systems and cyber training environments.

“CESI automates infrastructure deployment using Infrastructure as Code [IaC]. My team also helps develop and test cyber range scenarios,” he said. “We work closely with software and systems engineering teams to ensure systems are secure, resilient, and mission-ready. My work supports critical national defense initiatives, such as the Persistent Cyber Training Environment [PCTE].”

Leuck said he looks forward to continuing his education and advancing his cybersecurity skills. “I am eager to gain hands-on experience and apply what I’ve learned to support not only our warfighters but also the broader mission of the Department of Defense,” he said.

Advice for Incoming Cybersecurity, Computer Science Students

Leuck believes in the power of networking. “My biggest advice to incoming cybersecurity or computer science students is to start building your network early,” he said. “Connections in the industry often open doors to job opportunities that grades alone cannot.” 

Another important thing for CARDS students: Start studying for the cybersecurity certifications. “Industry-recognized certifications such as CompTIA Security+ demonstrate your commitment and foundational knowledge to potential employers.”

He suggests students explore areas that genuinely interest them, “whether it’s penetration testing, network vulnerabilities, or another specialization. Going beyond the classroom and investing in your own growth is what will ultimately set you apart in a highly competitive field.”
