Civil engineering is a great choice for people interested in building the infrastructure for the world of tomorrow. Some of the things civil engineers might look after include: water engineering, including how we supply fresh water, and treat wastewater to transport infrastructure, including roads and airports, building embankments for dams. Civil engineers made The Sydney Harbour Bridge a reality, helping to figure out a way a bridge that large could support its own weight. 

Mechanical engineering is all about product design, from robotics to energy planning and pollution control. Mechanical engineers can look after projects that focus on emerging sciences and ways to apply them, such as renewable energy, and solar energy towers. Some people combine a science degree with a major in engineering, blending their science with engineering principles. 

Mechanical engineers design and maintain machinery. This can include computer-aided design and manufacturing, using CAD/CAM. Other specialisations include consumer product design, automotive, robotics and control systems. 

The problems they are working on solving can be everything from what’s the best way to control noise, or pollution in various industries such as marine, oil, gas and aerospace industries. 

A principal highway engineer leads and manages design packages for major roads and highways. They are responsible for the project design from start to finish, including all details and delivery roll-out plans. In addition to this, they manage project teams to deliver on time and to budget. To secure a role like this, you would have significant experience delivering major road and highway projects, as well as experience as a mentor of junior engineers, topped off with exceptional communication skills. 

A software engineer creates products. They provide services or improvements to websites and apps. A product engineer (within software engineering) builds the designed product, such as a food delivery app. If the designer has requested certain things, which are outlined in mock-ups, an engineer works on how they will implement it in practice. Software engineers, including product engineers, work closely in collaboration with project managers and designers. The engineer then works on the process of building, including the reading, writing and fixing code. No two days look the same. 

Transport engineers plan and execute projects that look after this infrastructure. It could include a massive highway upgrade, or a roll-out of a new transit hub for a community. They plan, design and operate these systems that connect people and places, such as roads, bridges, airports, and transit stations.
