Sub-Disciplines
There are many sub-disciplines in Electrical Engineering. Some Electrical Engineers specialize exclusively in one sub-discipline, while others specialize in a combination of sub-disciplines. The most popular sub-disciplines are electronics, microelectronics, signal processing, power, control, telecommunications, and instrumentation computer engineering.
A Variety of Projects and Using CAD
Electrical Engineers work on a variety of projects, such as computers, robots, cell phones, cards, radars, navigation systems, wiring and lighting in buildings, and other kinds of electrical systems. Electrical Engineers are increasingly relying on Computer-Aided Design (CAD) systems for the creation of schematics and layout circuits; they use computers to simulate how electrical devices and systems will function.
Skills and Tools
Electrical Engineers work in various industries, and the skills required also vary. These skills can range from basic circuit theory to those needed to be a project manager. For example, some work in defense-related and nuclear power industries has country-specific security implications and requirements. The tools and equipment that an Electrical Engineer may need are also variable. They can range from a straightforward voltmeter to a top end analyzer to advanced design and manufacturing software.
Overseas Jobs
A second language may be useful when applying to international companies. There are excellent opportunities to work overseas, particularly in the oil, petrochemical and power sectors, large consulting firms, and large building contractors. It could be either an overseas posting with a multinational employer or by applying for a job based overseas.
Self-Employment & Consultancy
Self-employment and consultancy are natural options for individuals with adequate knowledge, expertise, experience, and a good reputation.
Potential Pros & Cons of Freelancing vs. Full-Time Employment
A freelancer Electrical Engineer has freedom in regards to flexible schedules, working hours and location. They have full ownership of the business and can afford selectivity in terms of the variety of projects and clients presented. While it has unlimited earning potential, it also has less stability and security, with inconsistent work and cash flow. There is more responsibility, effort, and risk involved. Paid holidays and sick/maternity/paternity leaves become unaffordable. There is the added pressure of a self-employment tax and no eligibility for unemployment benefits.
A full-time Electrical Engineer, however, has access to company-sponsored health benefits, insurance, and retirement plans. They have job security with a fixed, reliable source of income and guidance from their bosses. They are susceptible to potential boredom and inability to pursue passion projects due to their lack of time or effort. There is a lack of flexibility, ownership, and variety, and need to budget extra money for commuting and attire costs.
