What is software engineering? (original) (raw)

It involves applying engineering principles to the software development lifecycle and the use of various tools and techniques to create high-quality software products. This process is informed by engineering techniques, which help define, implement, assess, measure, manage, change, and improve the software over its lifetime.

Software encompasses a wide variety of applications, including operating systems, desktop programs, games, and mobile apps. Every industry uses software apps in some way—data management, customer interfacing, and operations can all be managed using software apps.

Engineering software requires not just the development of the application but also the maintenance as hardware, related software, and user needs evolve over time.

Types of software engineers

There are many different types of software engineering roles, each with its own set of responsibilities and requirements. Some of the most common types of software engineering roles include:

• Application developer: The person in this role creates software applications and programs using tools designed for development as well as programming languages—such as JavaScript, HTML/CSS, SQL, Python, and Java.
• Architect: The person in this role designs and develops software systems and applications at a high level. They determine project requirements and build technical standards for tools, platforms, or software coding. A development team then uses these designs and standards to develop software.
• Project manager: The person in this role handles the process of software development from start to finish by organizing workflows, assigning tasks, and monitoring progress to meet benchmarks or deadlines.
• System developer: The person in this role builds the operating system that underpins all backend computer functions. These systems are the foundation of not just desktop devices but also mobile devices, automobiles, IT networks—anything that relies on a computer to operate.
• Tester: The person in this role designs tests to help ensure that software applications meet certain standards of quality and performance. They also run these tests and analyze the results to make improvements or recommendations.

Software engineering roles and responsibilities

The roles and responsibilities of a software engineer can vary depending on the specific job, industry, and company. Some common day-to-day responsibilities include:

• Designing and developing software systems and apps: Designing and developing systems and apps involves writing code and debugging errors. Software engineers also design ways to test new code—either their own or code written for other programs that might be used with their systems—to ensure quality and performance control.
• Collaborating with other engineers and stakeholders: This type of collaboration includes working with other software engineers, project managers, and clients to ensure that software products meet their needs. Collaboration takes place throughout the project from the outset (when software requirements are defined) through completion (when the product is evaluated to make sure it meets its defined goals).
• Maintaining software systems applications: This involves fixing bugs, updating software, and ensuring that software products continue to function properly over time. The dynamic nature of evolving technology requires software engineers to continuously check on the health of systems and apps.

Popular software engineer skills

To become a software engineer, you need to have a combination of both technical and non-technical proficiencies. Some of the most important skills for software engineers include:
