Hardware Engineer: A Deep Dive into Electrical Engineering Concentrations

Hardware engineering, a vital branch of electrical engineering, focuses on the design, development, and testing of physical components of electronic systems. Unlike software engineering, which deals with the non-tangible aspects of computing, hardware engineering is concerned with the tangible, physical elements of technology.

The field has evolved significantly since the invention of the transistor in 1947. Milestones such as the development of the integrated circuit in the 1950s and the microprocessor in the 1970s have revolutionized the way we approach hardware design, leading to the compact, powerful devices we use today.

Educational Pathways

Academic Requirements

A Bachelor of Science in Electrical or Computer Engineering is typically required. Key courses include Microelectronics, which delves into semiconductor devices and IC fabrication techniques, and Digital Systems, focusing on logic design and microprocessors.

Advanced Degrees and Specializations

For those aiming for research or high-level industry roles, a Master’s or Ph.D. is advisable. Specializations can include Embedded Systems, where the focus is on integrating hardware and software for specific applications, and VLSI Design, which deals with the creation of integrated circuits.

Certification and Licensing

A Professional Engineer (PE) license, obtained after passing the FE and PE exams and gaining relevant work experience, is crucial for higher responsibility roles. Certifications like the Certified Hardware Engineer can also add value.

Core Skills and Technologies

• Technical Skills. Essential skills include circuit design, proficiency in CAD tools like Altium (used by over 35% of professional engineers), and a deep understanding of semiconductor devices.
