What skills help Security System Engineers find jobs?

Tell us what job you are looking for, we’ll show you what skills employers want.

What skills stand out on security system engineer resumes?

David Garaventa

Director, Computer Information Systems and Cybersecurity Programs, Assistant Professor, CIS, Albertus Magnus College

The skills/attributes required across a variety of jobs in the IT fields.

What soft skills should all security system engineers possess?

David Garaventa

Director, Computer Information Systems and Cybersecurity Programs, Assistant Professor, CIS, Albertus Magnus College

Communication and collaboration skills are critical. Particularly now that many employees are working remotely, it has become more difficult - yet more important than ever - to have IT teams that work effectively together, even when they are not in the same room together. But this is not unique to the IT realm. Whether via remote meetings or through effective written communications, it is no longer enough to simply have "technical skills." Technical skills can be taught to employees more easily than developing employee's soft skills, so when an employee approaches their job with a strong set of communication skills and strong analytic reading and writing abilities, they can often make themselves stand out to employers. The employers will recognize that they have the attributes to be an asset to the team and can then invest in helping them develop any technical areas where they may be lacking.

This is not to say that technical skills don't matter, because they do, especially in the IT field. But suppose an employee brings a strong set of soft skills to an IT team (e.g., collaboration, communication, critical thinking, etc.). In that case, they probably also can learn more technical skills as part of their job function. I once had a colleague say to me that when she is hiring, she has found that technical skill is all over the place...but it's the soft skills that are harder to find. Lastly, having the ability - and a desire - to be continually learning is essential. Technology is not static, and businesses are not static, so thinking critically in different settings across various technology platforms is very important. The tools your department uses today may not be the tools they are using tomorrow, so being fluid, adaptable, and constantly learning is the name of the game.

What hard/technical skills are most important for security system engineers?

David Garaventa

Director, Computer Information Systems and Cybersecurity Programs, Assistant Professor, CIS, Albertus Magnus College

The technical skills that are required are broad and tend to be business and/or industry-specific. If you are working in healthcare IT, the patient management platforms you use could be different from the client database used by a bank's IT team, for example. So, on the one hand, the recommendation would be to determine what platforms are most commonly used in your industry area and spend time mastering those platforms. On the other hand, most industries tend to have specific tools that are most commonly used, and spending time mastering those is important.

Going deeper into the subject, technical skills around project management, cloud infrastructure, security, and end-user support bridge across all industries. Having knowledge and skills in these areas will serve IT professionals well, no matter what field or industry they end up in. Again, it is challenging to recommend specific technical skills because the field of IT is so broad.

What security system engineer skills would you recommend for someone trying to advance their career?

Professor David Sanford

Associate Professor an Department Chair (MIS, CS, CYB MGT, IS CYB), Northwood University

Here's some of what they may do on a typical day: Develop and install computer systems and programs to ensure they meet company needs. They all ensure that computers can talk to each other and the internet without interference. Some may set up Virtual walls and put locks in place to keep the bad guys out and ensure the company's information is secure. From a technical aspect, if something goes wrong, they jump in and fix it ASAP to get everything running smoothly. They are the go-to people when others in the company have computer problems. They are supported and taught how to use new technology. From a data perspective. some handle important information and make sure it is organized and accessible when needed. Many manage large tech projects and ensure efficiency within an organization through the integration or creation of new technology. Some perform managerial duties such as developing and maintaining guidelines and manuals so that everyone can learn how to use the system(s). In this field, employees are constantly learning about new tech and products to stay on top of their game. They analyze this new technology to determine if it could be used within their organization to increase efficiency or improve a business process. In all. for someone just starting out in this field, they can spend their days teaching, running small projects and helping the team. As they gain more experience, they will face bigger challenges and learn new things.

What type of skills will young security system engineers need?

John Ring

Director Engineering Outreach, Elon University

While our universities consistently educate engineering students with hard skills and strong engineering fundamentals, tomorrow's engineers need to be strong communicators, collaborators, and critical thinkers. Our professional environments are filled with data and information, and the constraint is typically how much time individuals can dedicate to solving a problem. At Elon University, we educate tomorrow's engineers to have the hard skills necessary to analyze the information and situations, apply critical thinking techniques to determine ways to solve the issue, and then concisely and efficiently communicate with colleagues as solutions are being set in motion.
