Professions
A person with a profession in computer engineering is called a computer engineer.
Applications and practice
There are two major focuses in computer engineering: hardware and software.
Computer hardware engineering
According to the United States
BLS, job outlook employment for computer hardware engineers, the expected ten-year growth from 2019 to 2029 for computer hardware engineering was an estimated 2% and a total of 71,100 jobs. ("''Slower than average''" in their own words when compared to other occupations)".
This is a decrease from the 2014 to 2024 BLS computer hardware engineering estimate of 3% and a total of 77,700 jobs; "''and is down from 7% for the 2012 to 2022 BLS estimate and is further down from 9% in the BLS 2010 to 2020 estimate.''"
Today, computer hardware is somewhat equal to electronic and computer engineering (ECE) and has been divided into many subcategories, the most significant being
embedded system design.
Computer software engineering
According to the U.S.
Bureau of Labor Statistics
The Bureau of Labor Statistics (BLS) is a unit of the United States Department of Labor. It is the principal fact-finding agency for the government of the United States, U.S. government in the broad field of labor economics, labor economics and ...
(BLS), "''computer applications software engineers and computer systems software engineers are projected to be among the faster than average growing occupations''" The expected ten-year growth for computer software engineering was an estimated seventeen percent and there was a total of 1,114,000 jobs that same year.
This is down from the 2012 to 2022 BLS estimate of 22% for software developers.
And, further down from the 30% 2010 to 2020 BLS estimate.
In addition, growing concerns over cybersecurity add up to put computer software engineering high above the average rate of increase for all fields. However, some of the work will be outsourced in foreign countries. Due to this, job growth will not be as fast as during the last decade, as jobs that would have gone to computer software engineers in the United States would instead go to computer software engineers in countries such as India.
In addition, the BLS job outlook for Computer Programmers, 2014–24 has an −8% (a decline, in their words),
then a job outlook, 2019-29 of -9% (Decline),
then a 10% decline for 2021-2031
and now an 11% decline for 2022-2032
for those who program computers (i.e. embedded systems) who are not computer application developers. Furthermore, women in software fields has been declining over the years even faster than other engineering fields.

Integrated circuits, VLSI design, testing and CAD
This specialty of computer engineering requires adequate knowledge of electronics and electrical systems. Engineers working in this area work on enhancing the speed, reliability, and energy efficiency of next-generation very-large-scale integrated (
VLSI) circuits and microsystems. An example of this specialty is work done on reducing the power consumption of VLSI algorithms and architecture.
Signal, image and speech processing
Computer engineers in this area develop improvements in human–computer interaction, including
speech recognition
Speech recognition is an interdisciplinary subfield of computer science and computational linguistics that develops methodologies and technologies that enable the recognition and translation of spoken language into text by computers. It is also ...

recognition of human facial features.
Quantum computing
This area integrates the
quantum
In physics, a quantum (: quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. The fundamental notion that a property can be "quantized" is referred to as "the hypothesis of quantization". This me ...
behaviour of small particles such as
superposition
In mathematics, a linear combination or superposition is an expression constructed from a set of terms by multiplying each term by a constant and adding the results (e.g. a linear combination of ''x'' and ''y'' would be any expression of the form ...

Benefits of Engineering in Society
An accessible avenue for obtaining information and opportunities in technology, especially for young students, is through digital platforms, enabling learning, exploration, and potential income generation at minimal cost and in regional languages, none of which would be possible without engineers. Computer engineering is important in the changes involved in industry 4.0, with engineers responsible for designing and optimizing the technology that surrounds our lives, from
big data
Big data primarily refers to data sets that are too large or complex to be dealt with by traditional data processing, data-processing application software, software. Data with many entries (rows) offer greater statistical power, while data with ...
