What do software engineers do?
Successful engineers know how to use the right 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.
“I get excited about anything that involves solving problems, whether it be figuring out how to optimize a certain part of an existing application or entirely coming up with new applications to solve certain needs,” says Murtadha Al-Tameemi, a software engineer at meta “Problems in general stimulate my brain and give me a great sense of satisfaction.”
In this role, your day-to-day tasks might include:
- Designing and maintaining software systems
- Evaluating and testing new software programs
- Optimizing software for speed and scalability
- Writing and testing code
- Consulting with clients, engineers, security specialists, and other stakeholders
- Presenting new features to stakeholders and internal customers
Systems developer vs. application developer
Software engineers will usually fall into one of two categories,system engineers or application developers.
As a systems engineer, you’ll focus on things like software architecture and networks that applications need to function. You can do this by:
- Ensuring that different types of software programs communicate with each other on one platform
- Creating and enforcing IT infrastructure standards
- Maintaining documentation of IT systems
- Updating to new technologies as needed
- Collaborating with development teams, senior systems architects, and data science professionals
Working as an application developer is more client-focused. You may work on either the front or back end of the system, designing software that the end user will interact with. Tasks might include:
- Developing applications for iOS, Android, Windows, or other operating systems
- Conducting an analysis of requirements and tweaking software as needed
- Releasing software updates
- Working with graphic designers, customer service staff, project managers, and other customer-facing departments
If you’re interested in a more administrative software engineering position, learning technical project management strategies like dev ops is an excellent place to start. You can familiarize yourself with DevOps and the software development life cycle while earning a Professional Certificate for your resume by enrolling in the following online program:
Is software engineering a good career?
If you enjoy solving problems and have strong analytical skills, a career as a software engineer can be both fun and challenging. As technology continues to evolve, job growth for software developers continues to be much faster than the national average for all occupations [1].
Choosing a career as a software engineer gives you opportunities to work in many different industries and fields, as nearly all businesses use software. Whether you enjoy finances, entertainment, sports, real estate, or some other industry, there’s a good chance there are jobs for software engineers.
It’s also a career that allows flexibility in where you work. You may be able to work from home for companies in other states or even other countries. The important thing is that you’re able to meet deadlines and deliver a project on time.
How much do software engineers make?
Working as a software engineer can be challenging and engaging, and it also tends to pay well. The annual median software engineer salary in 2023 was $130,160, according to the US Bureau of Labor Statistics (BLS) [1]. Jobs in software publishing tend to draw the biggest salaries.
Career paths in software engineering
Once you become a software engineer, you can choose which path you want to take (applications or systems) and how far you want to progress with it.
