Expert Systems Engineering Professional

This certification is for those who have at least 25 years of experience in systems engineering and three references. Rather than an examination, recipients are subject to a peer review panel.

Certified Information Systems Security Professional

Offered by the International Information System Security Certification Consortium, the Certified Information Systems Security Professional (CISSP) shows an individual's ability to design and implement cybersecurity programs. Successful candidates have five years of systems security experience and pass an examination.

Professional Engineer

The Professional Engineer (PE) is a common license required for engineers who plan to work with the public. Each state has different requirements to earn a PE, though a bachelor's degree from an accredited school, four years of experience under the supervision of a licensed engineer and a passing grade on the Fundamentals of Engineering exam are standard.


Systems engineers use several soft and hard skills to help them do their job well. Here are some examples:

Technical skills

This requirement varies depending on the industry in which the systems engineer works but requires being adept at planning software, modeling software and specialized equipment. IT systems engineers typically have a comprehensive understanding of data architecture, cloud computing and cybersecurity. This helps them develop and maintain protected internal data systems.

Functional modeling

Systems engineers build functional models, which demonstrate how various parts of a product interact with one another to produce the intended outcome. They develop specifications and diagrams to support and contextualize these models, and in creating them, they may clarify how to design and construct the final product to maximize its efficiency.

Analytical skills

A systems engineer's job requires a detail-oriented and meticulous analysis of each task they complete. They view a system as a whole and a sum of its parts. They also identify small details and make alterations. Sometimes, they implement large-scale changes to an entire system. Systems engineers also apply specific types of analysis to identify issues, clarify expectations and devise solutions, such as:

  • Needs-means analysis

  • Function-means analysis

  • Systemic textual analysis

  • Viewpoint analysis

Risk management

Systems engineers examine existing systems for weaknesses and opportunities for improvement, and risk management skills help them assess the likelihood and cost of system vulnerabilities. The following capabilities are critical for systems engineers involved with risk management:

  • Risk impact assessment

  • Risk prioritization

  • Risk mitigation planning

Time management

System engineers prioritize tasks, make and adhere to deadlines and create timelines for work completion. They also adjust to changes that occur in real-time and predict changes and plan accordingly. All this requires an ability to manage time and plan accordingly.


Systems engineers may work with a variety of different professionals. During a workday, they may interact with a marketing professional, a software engineer, a senior finance executive, a manufacturing plant member and a driver. It's important to develop clear and open communication methods to ensure they can explain technical information in simple terms to those outside of the engineering field.


Systems engineers collaborate on teams with designers, security experts, researchers, salespeople, manufacturing plant employees and marketing employees to launch a product. Effective engineers can delegate tasks, follow up on progress, conduct quality checks and offer constructive feedback.

Systems engineer work environment

Systems engineers can work in nearly any industry. Some aspects of a system engineer's work environment are consistent:

  • Systems engineers use technology constantly, including specialized software, security systems, modeling systems and plant equipment.

  • Products, requirements and standards are constantly evolving, so systems engineers stay current with new technology and update their knowledge to stay current.

  • System engineers work in person or remotely with people from many other fields, including other engineers and technology specialists, clients, financial specialists, public relations personnel and plant employees.

  • Although systems engineers typically work in offices, they may travel to facilities and job sites to inspect processes, manufacturing lines or server storage areas, depending on their industry.

  • Systems engineers generally work full-time during normal business hours, though some overtime may be necessary to meet deadlines.

Systems engineers are present in most industries. They can find employment with government agencies, nonprofits or private companies. Common industries include:

  • IT

  • Consumer goods manufacturing

  • Civil engineering

  • Health care

  • Agriculture

  • Finance and banking
