What is Software Engineering?

Software engineering is the branch of computer science that deals with

the design, development, testing, and maintenance of software
applications. Software engineers apply engineering principles and knowledge
of programming languages to build software solutions for end users.
Software engineers design and develop computer games, business
applications, operating systems, network control systems, and middleware—to
name just a few of the many career paths available.
A career as a software engineer can be both fun and challenging with
opportunities to work in almost any industry, including large and small
businesses, government agencies, nonprofit organizations, healthcare facilities,
and more. And as technology continues to evolve, the need for software
developers continues to grow. Many companies are also shifting towards hiring
software engineers who work from home, allowing for increased flexibility
and more opportunities to enter the field.
What Careers Are There in Software Engineering?
Career opportunities in software engineering are driven by new technologies in
automobiles, aviation, data management, telecommunications, factory control,
robotics, defense, and security. Software engineers may develop computer
games, business applications, operating systems, network control systems, and
more. A bachelor's degree or higher is often required to work as a software
engineer.
Two common jobs within software engineering are applications developers and
systems developers.
Applications developers design computer applications, such as games, for
consumers. They may create custom software for a specific customer or
commercial software to be sold to the general public. Some applications
developers create databases or programs for use internally or online.
Systems developers create operating systems, either for the public or for an
organization. These operating systems keep computers functioning and control
most of the consumer electronics in use today, including those in cell phones
and cars. Often, systems developers also build the interface that allows users
to interact with the computer.
Of course, applications and systems developer jobs are not the only two
positions available in the field of software engineering. Other common roles
include mobile developers, applications architects, quality assurance analysts,
and database administrators.
Some common job titles for software engineers include:
 Applications Architect
 Applications Developer
  Computer Applications Engineer
 Database Administrator
 Mobile Developer
 Program Manager
 Programmer
 Project Leader
 Quality Assurance Analyst
 Software Engineer
 Software Quality Engineer
 Systems Analyst

What Tasks do Software Engineers do?
Successful software engineers use programming languages, platforms, and
architectures to develop everything from computer games to network control
systems. In addition to building their own systems, software engineers also
test, improve, and maintain software built by other engineers.

Day-to-day tasks for a software engineer might include:

 Designing and maintaining software systems or applications
 Evaluating and testing new software programs
 Optimizing software for speed and scalability
 Writing and testing code
 Ensuring platform compatibility
 Creating and enforcing IT standards within an infrastructure
 Maintaining documentation of IT systems
 Releasing software updates
 Collaborating with development teams, senior systems architects, and
data science professionals
 Consulting with clients, engineers, security specialists, and other
stakeholders
 Recommending software upgrades for existing programs and systems
 Presenting new features to stakeholders and internal customers
WHAT IS A SOFTWARE ENGINEER?
A software engineer is a type of computer scientist who uses their expertise in
this specific branch of the discipline to design programs, applications and of
course, software. Their role involves creating, improving and maintaining
software so that it performs certain functions or meets specific requirements.
In software engineering, principles from science, mathematics and general
engineering are all combined to devise software solutions and new processes
to solve problems in a range of industries. Software engineers might work in
general roles where they develop new programs or contribute to the
development of software packages, or they might specialise in a particular
industry and just design software for specific devices or machinery. Embedded
systems and electronics software engineers are an example of this specialised
role.
Many people think that a software developer has the same role as a software
engineer, but whilst some of the responsibilities of the jobs are the same, they
approach projects from totally different perspectives. Software engineers tend
to take a broader view of creating or updating software and will be more likely
to work as a consultant or a project manager, ensuring that requirements are
fulfilled, deadlines are met and efficiency is maximised.
Every role will be different depending on the industry and the level of
responsibility you have, but typical tasks involved in a software engineer’s day-
to-day work include designing and creating plans for new software, program or
application development, evaluating and improving existing systems, writing
up technical specifications, establishing test procedures and monitoring
software performance.
6 OF THE BEST SOFTWARE ENGINEER SKILLS
A software engineer needs to have a good range of technical and practical
skills in order to competently carry out all that is required of them. The role has
its roots in maths and computer science as well as engineering, which means
that most jobs require a wide range of different hard skills.
Programming and Coding
Programming and coding are perhaps the most wanted software engineering
skills. Without the ability to write code and create programs and applications
from scratch, you won’t be able to perform the majority of software
engineering tasks.
Most software engineers are competent in several different programming
languages, such as Python, Java, TypeScript and C++. Some roles may require
you to learn specific coding languages to work on certain kinds of programs or
projects, but these will be easier to pick up if you already have a background in
learning code.
A lot of the information you need to build all kinds of software can be found
online, and as a software engineer you’ll be working as part of a team who can
share their ideas and experience when it comes to solving problems and
starting projects from scratch. However, it will benefit you to have
programming experience and the ability to write basic functions without any
assistance, especially if you’re starting at a junior level.
Object-Oriented Design (OOD)
Object-orientated design is a software engineer skill that has become more
sought after in the past decade or so. It refers to an approach to software
development that involves thinking about a program through the lens of object-
oriented design guidelines like abstraction and decomposition so that it is more
flexible and can be easily reused.
Understanding OOD will make you very desirable as a software engineering
candidate, and it is a skill that can be self-taught through various online
courses and training resources.
Testing
Designing new software is only a small part of what a software engineer is
responsible for. Every new program or system will have to be tested, refined
and then tested again until it is decided that it meets certain requirements and
standards, and understanding this test process is an important skill needed for
software engineering.
You may need to design tests for the software you work with, as well as running
them and identifying any errors or bugs that are uncovered. Whilst more and
more companies are starting to use automation and AI software to carry out
software tests, software engineers will still benefit from an understanding of
these processes and some practical experience running them.
Debugging
After the testing stage, any issues or bugs that have been identified will need
to be resolved. Debugging is a software engineering skill that requires
analytical and lateral thinking to identify where a problem is coming from and
how to remove it, followed by setting up protections that will minimise the
chances of it happening again.
Debugging skills tend to come from experience, as each scenario is different
and there is no single solution to fixing a problem in code.
Database Administration
Databases are a key part of the software and application development process.
Almost every kind of software engineering project will involve some kind of
interaction with a database, and being comfortable with navigating records and
updating or modifying these will make the majority of jobs much easier.
Employers are also likely to be looking for candidates who exhibit database
administration skills, particularly those who can use SQL.
Software Development
This might seem like an obvious suggestion for essential skills needed for
software engineering, but experience and understanding of software
development and the software development lifecycle is an important part of
the role. Knowing the correct procedures to follow and the stages required to
conceptualise a piece of software from ideation to release is particularly
important in more senior roles, which plenty of software engineering
opportunities are.
