Software engineers design and create computer systems and applications to solve real-world problems.
Software engineers design, develop, and test software applications and computer systems. If you’re an analytical thinker who enjoys solving problems and making technology easier to use, you may find a career as a software engineer rewarding.
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.
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
You can learn software engineering from Meta in just 7 months by enrolling in the Meta Front-End Developer Professional Certificate program:
Systems developer vs. application developer
Software engineers will usually fall into one of two categories, systems engineers or application developers.
As a systems engineer, you’ll build things like computer systems 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 standards within an infrastructure
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 DevOps is an excellent place to start. You can familiarize yourself with DevOps and the software engineering 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, the need for software developers continues to grow much faster than the national average [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 2022 was $124,200, 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. You can decide to advance toward a role as a senior software engineer, or you can continue gaining certifications and experience to advance to roles like IT project manager or systems manager. As a software engineer, you have both flexibility and mobility to create the career experience that is most appealing to you.
Aspiring software engineers who haven't yet chosen a specialization can benefit from foundational training. You can master the basics in just two months by enrolling in IBM's flexible online program:
How to become a software engineer
Getting a job as a software engineer typically involves building the right technical and workplace skills. Some jobs might also require a certain degree or certification to validate your skills. However, there are many ways to enhance your skill set.
"Although I did have a formal education, taking online classes on how to build mobile apps, doing internships where I work on projects at a company, and trying to build my own side projects was the most helpful," says Laila Rizvi, a software engineer at Meta.
Let’s take a closer look at some of the requirements for becoming a software engineer.
Software engineering skills
As a software developer, you’ll be designing software to help solve problems that real people face. This requires a combination of technical know-how and solid communication skills. If you’re considering this as a career, here are some skills you should focus on building:
Coding languages like Python, Java, C, C++, or Scala
Object-oriented programming
Database architecture
Agile and Scrum project management
Operating systems
Cloud computing
Version control
Design testing and debugging
Attention to detail

Software engineering certifications
By earning a certification, you can build new skills and validate those skills to potential employers. Some jobs might require a specific certification, so it’s a good idea to research some job listings of roles you’re interested in before preparing for a certification exam. Here are some common options:
Certified Software Development Professional (CSDP)
Certified Software Engineer
C Certified Professional Programmer (CLP)
C++ Certified Professional Programmer (CPP)
AWS Certified Developer
Microsoft Certified: Azure Fundamentals
Do I need a degree to be a software engineer?
A bachelor’s degree in computer science or a related degree program is a common entry-level requirement for software engineers. However, a degree isn’t the only path toward a development job. Some employers accept alternative credentials such as certifications and equivalent experience in lieu of a degree. Research job postings for positions you're interested in to determine whether or not a degree is essential for your career path.
