History of Software Engineers
In 1963, Margaret Hamilton, coined the term software engineering while working on developing the software for the Apollo spacecraft. At this time, software development faced a crisis in trying to keep up with the progress in hardware development. This period led to the rise of software engineering by introducing new programs and languages.
In 1968 and 1969, the NATO Software Engineering Conference took place, giving the software engineering industry a much-needed boost. By the 1980s, software engineering secured its place alongside the computer science and traditional engineering professions.
What Is a Software Engineer?
Software engineers create web applications, mobile apps, robots, operating systems, and network systems. They develop software solutions that meet their companies' needs and expectations. Note that the terms "software engineer" and "software developer" are used interchangeably in the industry, but these positions' responsibilities vary slightly.
Software engineers design software solutions, while software developers build those solutions to make them ready for consumers. Depending on the type of company they work for, software engineers will create original code for software and applications. They also build reusable code for future use.
What Does a Software Engineer Do?
Computer software engineers develop programs and operating systems for computers. They work with system programmers, analysts, and other engineers to design systems, project capabilities, and determine performance interfaces.
Computer software engineers also analyze user needs, provide consultation services to discuss design elements, and coordinate software installation. Designing software systems requires engineers to consider mathematical models and scientific analysis to project outcomes.
The demand for skilled computer software engineers continues to grow. The Bureau of Labor Statistics (BLS) projects that software developer, analyst, and tester jobs will increase by 25% between 2021 and 2031, five times faster than the national average.
Computer software engineers can find employment in almost any industry since most companies use software. In fact, the BLS projects over 682,000 new computer and information technology jobs. As companies have more complex software needs, they need software engineers to create new programming applications and tools.

Main Duties of Software Engineers
- System Design: System design involves defining the outline for web applications and products efficiently and clearly. These designs provide information and data in the coding framework for the software developer to make the product.
- Establish New Documentation: All new technology requires documentation for people to understand its functionality. This might look like creating or updating products and supporting documentation. The software engineer writes this supporting documentation.
- Maintain Software Functionality: Software engineers maintain existing software and create new software. This includes making updates to align with the latest industry and company standards, troubleshooting problems, and brainstorming future improvements. Maintenance is equally as important as writing new code.
- Troubleshoot and Upgrade Existing Systems: Along with maintaining existing systems, software engineers also troubleshoot problems when they arise. Both internal company systems and clients may need help solving problems. Software engineers also make updates as needed to ensure existing systems remain usable.
- Comply with Company and Industry Standards: Technology is a rapidly changing field. Products and systems must keep up with these changes. Software engineers usually oversee these updates. They must match industry trends and ensure their systems align with industry standards.
Nonstandard Duties for Software Engineers
- Work with Clients: Many software engineers do not work directly with clients. However, working at a small company or startup can change this dynamic. If a software developer leads a project, they might regularly consult with the client to ensure the final product meets their expectations.
- Manage Internal Teams and Projects: Software engineers might manage internal teams and projects depending on the company and their roles. Experienced software engineers in a senior-level role at the company typically oversee teams.
- Interview and Hire for New Positions: If a new hire is being interviewed for their team, software engineers might speak with the job candidate to ensure a good fit. The final selection to fill roles usually falls on upper management. Still, a software engineer’s feedback is taken into consideration.
- Collaborate with Front-end Developers: Software engineers do not usually handle front-end development, but they might partner with front-end developers on some projects. In some cases, the front-end developer needs feedback from the software engineer to ensure they create a great product.
- Build Software with Code: A software engineer writes the code and creates the framework then a software developer executes the build. However, depending on the company and job description, software engineers might create new software with the developer.
Key Soft Skills for Software Engineers
Communication: Software engineers must be adept in communication, problem-solving, and teamwork. They may report progress to a supervisor, explain a product to a client, or coordinate with team members to work on the same product. Multitasking: Software development can require engineers to split attention across different modules of the same project, or switch easily between projects when working on a deadline or meeting team needs. Organization: To handle multiple projects through their various stages and keep track of details, software engineers must demonstrate a certain level of organization. Busy supervisors oversee entire teams and must access information efficiently at a client's request. Attention to Detail: Concentration plays a critical role for software engineers. They must troubleshoot coding issues and bugs as they arise, and keep track of various complex details surrounding multiple ongoing projects.
Key Hard Skills for Software Engineers
Data Structures: Programmers and software engineers use data structures and algorithms to build computer programs. Engineers' skills in data structures and algorithms help them create efficient and well-optimized code. Software Testing: Software engineers test new programs and applications to evaluate and verify features and functionality. This improves performances and fixes defects. They must also know the software development lifecycle to plan, test, and deploy systems. Programming Languages: Software engineers write code for computer programs and applications. Some popular languages include Python, C++, and Java. Core Computer Science Knowledge: Software engineers need a strong understanding of computer science concepts like databases, operating systems, and computer networking. Professionals use database management systems like SQL and must know various operating systems, including Linux.
A few of the most popular programming languages software engineers need to know include:
A Day in the Life of a Software Engineer
Software engineers' daily responsibilities can vary depending on their position. They may work with clients or executives to develop projects and design programs to meet those expectations. They also assemble charts and diagrams, write code, and supervise a team of programmers. Software engineers also run tests and fix issues that may occur with the programs.
Software Engineer Career and Salary Outlook
Salaries for software engineers can vary based on the industry, location, and the employee's years of experience. Payscale reports an average salary of $89,160 for software engineers as of September 2022. With experience, software engineer salaries can grow rapidly, with the average rising to $94,000 for those with 5-9 years of experience.
While the BLS does not distinguish between software engineers and developers, reports for these occupations highlight particularly lucrative industries and states in the field. Software developers earn a median annual wage of $109,020.
California ranks highest in the nation for software developer salaries, with an annual average salary of $146,770. Washington is next on the list, with an average salary of $145,150. Maryland ranks third, followed closely by New York and Rhode Island.
