What are the Different Types of Engineers?

Engineering is among the most diverse and impactful professional fields, driving innovation across every industry. Engineers apply principles to create solutions for complex issues, ranging from skyscrapers to lifesaving health technologies that shape our world. 

With engineering services projected to gross $312.5 billion by 2025 and a 3.4% growth rate, studying one or more engineering disciplines has never been more relevant for individuals looking to pursue this rewarding line of work. Here are some popular engineering fields and specialties. 

Chemical Engineer

Chemical engineers use mathematics, biology, physics, and chemistry principles to solve problems in producing or utilizing chemicals, fuel, pharmaceuticals, food, and other products. They design processes and equipment for large-scale manufacturing, organize and plan production procedures, and supervise operations.

Chemical engineers work at the crossroads between molecular science and mass-scale production, taking innovations from the lab and using them to advance our daily lives commercially. As of 2023, chemical engineers averaged an annual salary of nearly $121,860, reported the U.S. Bureau of Labor Statistics, and a 10% growth rate is projected through 2033.

Specialties Within Chemical Engineering

Biomedical Engineering: They apply principles from chemical engineering to the fields of biology and medicine, designing pharmaceuticals, artificial organs, and clinical diagnostic equipment. They bridge the gap between engineering and medicine, combining to create everything from drug release systems to implantable biocompatible materials.

Process Engineering: Process engineers create, set up, and refine chemical production procedures. They work mainly on industrial equipment, making it efficient, secure, and environmentally compliant and maximizing output. They apply their work to anything from petroleum refineries to food processing plants.

Environmental Engineering: It involves solving environmental issues using chemical solutions. Environmental chemical engineers design water purification, air pollution, and waste treatment systems. Their activities are more important than ever, as industries turn to sustainable means to help them leave less impact on the environment.

Civil Engineer

Civil engineers design, construct, and maintain the physical and naturally formed environment, such as roads, bridges, canals, dams, airports, sewers, and buildings. Civil engineering is an ancient field of engineering and is the backbone of infrastructure development on which modern civilization relies.

These professionals make buildings usable, safe, affordable, and sustainable. Civil engineers must consider weather patterns, geology, and population when designing buildings that communities will utilize for decades.

Specialties Within Civil Engineering

Structural Engineering: Structural engineers plan and calculate load-bearing structures such as buildings, bridges, and towers. They calculate how structures will react to weather, earthquakes, and everyday usage and ensure they will be safe and secure throughout their lifetime.

Transportation Engineering: Transportation engineers design, plan, operate, and manage transport systems, such as highways, railways, airports, and harbors. They research flow dynamics, predict demand for the future, and develop solutions that provide the highest mobility while lessening environmental impact and improving safety.

Geotechnical Engineering: Geotechnical engineers learn about soil and rock mechanics to understand how those materials will interact with human-created structures. Their knowledge is useful for foundation design, tunneling, and slope stability analysis, which can prevent catastrophic failure in large infrastructure projects.

Electrical Engineer

Electrical engineers design, make, test, and manage the production of electrical machinery, from electric motors and power generation systems to navigation and communication systems. What they create drives our modern world, enabling everything from home appliances to international telecommunication systems.

Electrical engineering is a rapidly changing field as technological progress raises new specializations and prospects. Electrical engineers concentrate on electrical systems and energy and develop technologies that help enhance efficiency and functioning across different industries.

Specialties Within Electrical Engineering

Power Systems Engineering: These engineers design and maintain electrical power grids, generation facilities, and distribution networks. They deliver secure electricity to residential, commercial, and industrial consumers and develop solutions incorporating renewable energy sources for a sustainable world.

Electronics Engineering: Electronics engineers work with small electrical systems and components, and design and develop devices and circuitry for use within consumer electronics, communications, and computers. They work with microprocessors, integrated circuitry, and other components, which are the foundations of contemporary technology.

Control Systems Engineering: This involves creating and implementing systems to control, command, direct, or regulate the functioning of other systems or equipment. Control systems engineers create everything from thermostats to complex industrial control and robot control systems, which enhance accuracy and efficiency.

Mechanical Engineer

Mechanical engineers design, construct, and evaluate mechanical systems and products. They can be as small as microchips and sensors or as large as machines, generators, and turbines. These versatile individuals apply principles of movement, energy, and force to create solutions to issues within nearly every field.

One of the broadest and most diverse fields, mechanical engineering offers numerous opportunities for specialization and career paths. The field is part art and part science, allowing engineers to translate concepts into physical objects to solve real-world problems.

Specialties Within Mechanical Engineering

Automotive Engineering: Automotive engineers design and construct cars and subsystems. They also create and implement new technologies, such as electric power and autonomous features, to make the automobile better, safer, more fuel-efficient, and environmentally sustainable.

HVAC Engineering: These design heating, ventilating, and air-conditioning systems for structures ranging from houses to large offices. They must balance comfort and energy usage against environmental and building codes.

Robotics Engineering: Robotics engineers apply mechanical engineering, electronics, and computer science principles to design and develop automated machines and systems. They create robots for production, health care, and exploration applications, among numerous other purposes, and design machines capable of performing repetitive tasks with high accuracy.

General Engineer

General engineers have broad knowledge across engineering disciplines and thus can look at issues from a systems perspective rather than from individual disciplines. They are versatile and thus applicable to fields such as project management, consultancy, and interdisciplinary subjects where broad knowledge is desirable.

These engineers typically liaise between specialist engineering teams to facilitate the integrated design of diverse components into functioning systems. They work from a systems perspective that can recognize issues that are often underappreciated when disciplines work separately.

Specialties Within General Engineering

Systems Engineering: Systems engineers lead complex engineering projects from a systems perspective. They coordinate the efforts of skilled teams, manage technical risks, and ensure that everything operates together seamlessly to meet project aims.

Engineering Management: They apply engineering and business principles to lead technical organizations and teams. They translate technical requirements into strategic plans, make resource decisions, and lead projects from planning through implementation.

Sustainability Engineering: Sustainability engineers use concepts from different disciplines to design environmentally friendly solutions. They evaluate the environmental impact of products and processes throughout their lifetime, looking for strategies to reduce natural resource use and waste generation.
