Software Engineers do the complex work so that we can enjoy efficient software solutions. They’re creating the systems behind the digital tools we use at work or in our personal life.
This takes strong logical thinking and problem-solving skills, as well as a deep knowledge of computer science and programming. It’s a challenging, but exciting career, and – as we’ll get into shortly – a highly profitable one.
If you’re technology-affine, have an analytical mind, and love to create slick solutions to people’s challenging problems, Software Engineer could be a fulfilling career for you.
What is Software Engineering, exactly?
Software Engineering is a discipline of Computer Science that’s dedicated to architecture, development, testing, deployment and maintenance of computer programs. It’s called Software Engineering because engineering concepts are used – together with computer coding – to create software that fulfills the needs of users.
What does a Software Engineer do?
Software Engineers are asked to carry out manifold tasks on the job. Not only do they design software – they create its code, test and debug it and deploy (release) the software. Ultimately, they need to keep monitoring and updating the “finished” product.
Tasks & responsibilities
- Software architecture / design. Software Engineers create the architecture of a software – the blueprint of how its different parts will work together to create the finished product. They also design each individual part of the software.
- Developing software. Using their deep knowledge of computer programming, Software Engineers also create the code that makes up a software program.
- Analyzing software solutions. They’re experts at analyzing their own software, or that created by others, using a high-level, engineer’s view.
- Code-testing. Engineers are known for leaving nothing to chance, and the same applies to the software field. Each step of the way, tests are written and executed to make sure each software feature is working as intended.
- Debugging software. Once an error is found in the code, the engineer will try to get to its “fix the bug” by addressing its root cause, in a way that avoids causing other problems down the road.
- Optimizing software. Many times, a software doesn’t run as fast as it could, or is generally designed in an inefficient way, with a bloated codebase. A Software Engineer’s task is to detect these inefficiencies and clean them up, optimizing the software for performance, scalability and maintainability.
- Monitoring a software’s performance. They have a responsibility to ensure a software is running optimally under real-world conditions. Performance has to be measured and tracked in both normal and system-stressing situations.
- Consulting with team members and clients. Counter to the cliché, Software Engineering isn’t a solitary affair. To work most productively as a company, and stay in line with client requirements, collaboration and communication are crucial parts of the job.
- Maintaining and updating software. After successfully deploying a new software product, the engineer’s work is not done. Most software has to constantly be adapted to new demands, be they additional features, compatibility changes, or emerging security threats.
Where do Software Engineers work?
- Tech companies. Software Engineers work at large companies like FAANG (Facebook, Amazon, Apple, Netflix, Google), but also medium-sized and small tech companies. These jobs come with a high level of responsibility, challenging and often cutting-edge work assignments, and
- Traditional companies. Nowadays even companies in traditional fields such as agriculture or construction have digitalized some of their operations. They’re using Software Engineers to create the software to handle various tasks inside their businesses.
- State institutions. Agencies like the IRS, DoD or NASA look to Software Engineers to build the most secure software for their needs.
- Startups. Tech startups employ Software Engineers to develop the new software they want to bring to market. These positions give you the opportunity to work in a fast-paced, creative environment, working on solutions that can change industries, or the world.
- Education. Engineers are needed to develop programs for research institutions or colleges. They can also become teachers or professors of Software Engineering or Computer Science.
Salaried employment vs freelancing
Working for a paycheck and benefits is not the only way for Software Engineers. A profitable career as a Software Engineering freelancer is also possible. Either way, the nature of the job means it lends itself well to remote work and setting your own hours.
The types of software created by Software Engineers
- Desktop software. These are PC programs that run on code and interact with the user by means of a graphical interface. This could be anything from calculator apps to music players.
- Web applications. Software Engineers also create online apps that can be accessed with a web browser. Online shops, e-banking or almost any software-as-a-service (SaaS) app fall under this category.
- Mobile apps. Apps for tablets and mobile phones have to be expertly engineered, too, so Software Engineers are called on to develop navigation apps, personal development apps, mobile games, and the like.
- Embedded systems. Embedded systems are microcontroller based systems such as alarms, household machines, or digital cameras.
- Operating systems. Systems Developers or Engineers work on the foundation for modern personal computing: The operating system.
- Management software. For larger companies, Software Engineers are creating software systems for the management of customer data, human resources, or company assets, for example.
Why Software Engineer?
One of the biggest perks of a Software Engineering job is the impressive salary it can generate for you. According to the Dice Tech Salary Report, the average US salary for a Software Engineer is $111,000.
The exact salary a Software Engineer will make depends on different factors:
- Location and size of the company
- Field of specialization/special skills
For example, as a QA Engineer with less than a year of experience, working for a company in Tennessee, you might make only around $50,000 per year.
As a Cloud Engineer with 5-10 years of experience, working in California, on the other hand, your yearly salary could be between $130,000 and $150,000.
According to conisar.org, Software Engineers rate how satisfied they are with their job at 3.69 / 5 on average.
Stack Overflow found that what they like most about their jobs are “salary (60 percent), work-life balance (58 percent), flexibility (52 percent), productivity (52 percent), and growth opportunities (49 percent)”.
70% of Software Engineers are happy about their work overall. This is 5% above the average job satisfaction rate in the US.
Remote work ability
Remote work makes Software Engineers more productive. And because all their tasks can be completed over the internet, it’s the perfect profession to go remote in. Around 80% of Software Developers and Engineers are working remotely or in a hybrid environment today.
According to the Bureau of Labor Statistics (BLS), jobs in software development will grow by 25% within the decade – in contrast to only 5% growth in all industries on average. With emerging fields like Blockchain, Cybersecurity and Machine Learning offering new opportunities for Software Engineers, job outlook continues to look positive in comparison to other fields.

Software Engineer vs Software Developer
The job description of a Software Developer is very close to that of Software Engineer. Both use programming languages to create the code necessary for a software project.
But where they differ is that a Software Engineer also takes on the larger-scale task of designing the architecture of the software – which is where the required engineering skills come to fruition.
How to become a Software Engineer
There are different paths to becoming a Software Engineer — getting a degree, taking courses, or going completely self-taught.
Regardless of which path you went with: To have a chance in the competitive Software Engineering job market, the result needs to be that you’ve mastered certain hard skills (including one or more programming languages) and soft skills.
Essential Software Engineer skills
To be a great Software Engineer requires you to develop a number of skills to a high level. There’s the technical, or “hard” skills on one side, and the more intangible, (inter-)personal “soft” skills on the other. Both are essential for a successful career in Software Engineering.
- Object-oriented programming.
