Throughout history, engineers have propelled society forward. The ability to harness electricity, improving the efficiency of agriculture and developing medicines and lifesaving equipment for the betterment of human health — the influence of engineers on society is incalculable.

Think about the grand structures of our time, the tallest buildings in the world, the largest dams, or the longest bridges. These engineering feats are visible to everyone. What about the innovations taking place at the microscopic and atomic levels? Vaccines and medicines allow us to live longer lives. Atom splitting allows us to unleash immense force. Further consider the innovations that have taken society from the Stone Age to the modern era. Think about the invention of the wheel; the development of the space program in the 1960s; or the hyperscale data centers that allow us to stay connected with others, get information, or entertain ourselves. All these achievements are the fruits of the labor of engineers working in various disciplines

As new problems arise, engineers advance technology to help solve them. Still, as the world grows increasingly complex, 21st century engineering leaders must embrace an interdisciplinary approach to address challenges in technology, business, and society. The willingness to innovate across a complex global framework is essential to further technological advancement and build humanity’s long-term resilience in the face of familiar foes: climate change and disease.

A master’s degree and a professional engineering, or PE, license can help prepare engineers for an increasingly global society and to become leaders in their fields. A PE license is “the engineering profession’s highest standard of competence, a symbol of achievement and assurance of quality,” according to the National Society of Professional Engineers. The combination of an advanced degree and a PE license can position an engineer for increasing responsibility, including managing teams.

Engineers have become increasingly important, and organizations in industry, government, and academia seek to hire them. Science and engineering employment represents 5% of all U.S. jobs, exceeding the pace of overall workforce growth, according to “The State of U.S. Science and Engineering 2020” from the National Science Foundation. The median annual salary for occupations in science and engineering was $85,390 in 2017, according to the report: “more than double the median for all U.S. workers ($37,690).”

Employers often seek engineers with backgrounds in one of the four main branches of engineering: chemical, electrical, civil, and mechanical. However, engineering is a vast discipline centered on solving problems with innovative solutions, which makes it an evolving, expanding field. Popular engineering disciplines include biomedical engineering, aerospace engineering, and environmental engineering.
