Systems Engineer: Career Overview
Discover what a systems engineer does and the educational pathways that can help you enter the field.
Systems drive the contemporary business landscape. When well-designed and strategically implemented, these bring an efficient edge to business operations, limiting errors while boosting adaptability and scalability. If systems are outdated or poorly executed, however, they can prompt significant bottlenecks that prevent organizations from reaching their full potential.
This is where systems engineering comes into play. This discipline relies on broad industry expertise, including a unique blend of management and technical skills, to deliver major boosts in productivity while also limiting defects and bottlenecks. Systems engineers work to limit redundancies, enhance output, and deliver overall impressive returns on investment across numerous high-impact industries.
What Is a Systems Engineer?
Systems engineering is an interdisciplinary field that determines how interconnected components or processes (known as systems) can work together seamlessly to achieve specific objectives. This may encompass technical areas such as hardware and software as well as management capabilities, all applied to core elements such as system design, integration, and lifecycle management.
So, what is a systems engineer’s role in this context? Although variations exist across fields, systems engineering professionals are generally responsible for designing, implementing, and managing complex systems. Drawing from elements of engineering and management theories, this role places a strong emphasis on systems thinking, which demonstrates how individual components interact within overarching systems.
What Does a Systems Engineer Do?
Systems engineers work in a fast-changing environment, adapting to new challenges and project requirements as they arise. These skilled professionals oversee a range of functions within the systems engineering lifecycle:
- System design - Translate requirements into clear technical specifications, defining components, their functions, and how they fit together.
- Development - Oversee the system build, working with hardware and software teams to ensure everything aligns with the design plan.
- Systems integration - Combine individual parts into a working whole, troubleshooting compatibility issues along the way.
- Human-machine interaction - Ensure systems are safe, user-friendly, and designed to reduce error and support operator needs.
- Risk analysis - Identify and address operational or security risks before they disrupt performance.
- System optimization - Improve system efficiency and performance through testing, simulations, and ongoing adjustments.
How to Become a Systems Engineer
Systems engineering can be a rewarding field, but it's also demanding. Systems engineers must possess an advanced technical skill set, complemented by a strategic mindset, along with strong coordination and leadership.
These skills are gained through years of theoretical and hands-on training. This often begins with earning a bachelor's degree. At the undergraduate level, future systems engineers might explore computer science, industrial engineering, or mechanical engineering. The most relevant undergraduate programs explore technical concepts and soft skills, ideally delivering a well-rounded introduction to systems thinking.
Graduate-level programs offer higher-level training, providing a strong foundation in fundamental systems engineering principles plus core development methodologies. Georgia Tech’s Professional Master's in Applied Systems Engineering (PMASE) provides a comprehensive overview covering everything from systems design to simulation execution and relevant graphical modeling languages.
Systems Engineer Skills
Systems engineers showcase a diverse range of competencies, including technical expertise alongside interpersonal abilities. Both are vital to success in this interdisciplinary field.
Technical Skills
Sometimes referred to as hard skills, technical competencies draw heavily upon engineering principles but also encompass modeling, simulations, and many other analytical techniques that help systems engineers abide by stringent standards.
- Software development - Systems engineers should possess a thorough understanding of software architecture, design principles, testing methodologies, and even insights into embedded systems.
- Programming - Many programming languages support excellence in systems engineering. For instance, Python is favored for its versatility and broad support for simulation and automation. Other helpful programming languages include Java (for enterprise-scale systems) and C++ (for embedded systems). Furthermore, systems engineers should be intimately familiar with MATLAB/Simulink, which is frequently utilized across engineering disciplines.
- Networking - Systems engineers may be closely involved in the design and implementation of communication infrastructure. To that end, they must understand communication protocols and network topologies, along with data transmission methods and other insights that help them promote secure, efficient communications.
- Cloud computing - With a significant share of enterprises now reliant on cloud platforms, there is a firm expectation that systems engineers will have cloud literacy. This allows engineers to embrace cloud-first strategies.
- Information security - Insights into encryption and intrusion detection allow systems engineers to safeguard sensitive data while also enhancing system integrity and strengthening regulatory compliance.
- Risk management - Systems engineers should be able to anticipate various technical and operational risks across numerous lifecycle phases and develop strategies to prioritize and mitigate these concerns.
Workplace Skills
Beyond technical expertise, successful systems engineers rely on strong workplace skills to collaborate, solve problems, and keep complex projects on track.
- Communication - Explain technical concepts clearly, collaborate across teams, and build consensus with stakeholders.
- Troubleshooting - Use critical thinking and problem-solving to quickly identify and resolve issues during integration and other project phases.
- Attention to detail - Balance big-picture thinking with focused analysis to ensure accuracy throughout design, development, and risk analysis.
- Time management - Prioritize tasks effectively, manage competing deadlines, and coordinate with multiple teams.
Prepare for a Bright Future in Systems Engineering
Uncover meaningful opportunities within the world of systems engineering. Georgia Tech’s Professional Master's in Applied Systems Engineering (PMASE) helps working professionals develop a systems mindset, plus in-demand technical and management competencies. Learners take a deep dive into model-based systems engineering (MBSE), an approach that uses modeling and simulation to support requirements development, system design, analysis, verification, and validation across the full system lifecycle. It also helps systems engineers visualize complex interactions, reduce risk earlier in development, and improve cross-team communication.
"As someone who has worked in both document-centric and model-based systems engineering, I've seen incredible value in the technology that model-based systems engineering brings. It connects the digital thread and moves us toward what's often called digital twinning, enabling us to see results much more quickly," says PMASE alumni and mentor Christopher Phillips.
Offered online, this two-year degree program provides flexible, asynchronous coursework alongside three in-person learning opportunities at the beginning, midpoint, and end of the program. A final capstone helps students apply knowledge gained to real-world challenges. Contact us to learn more about our applied systems engineering program.
