A Software Engineer is a computer science professional who uses programming languages to build software products, develop applications and ultimately solve real world problems.
Software engineers are required to keep up to date as technologies evolve and to train their minds to respond to real-world problems. Their mathematical mind and understanding of algorithms provide them with both the technical and mental capabilities to perform complex tasks. One line of code at a time, capable software engineers walk their path as innovators within society, distinguishing themselves for their curiosity and ability to masterly pair hard with soft skills.
Software Engineesr are professionals in computer science. They leverage programming languages to create software products, design applications, and address real-world challenges.
Capable software engineers put effort into the creation of scalable, maintainable, efficient, secure apps, with a strong attention to user experience. They are expected to master programming languages, frameworks, databases, and APIs, alongside algorithms and data structures. They may need knowledge of pipelines and DevOps, and their code must not only be functional but also look neat.
A solid knowledge of software engineering fundamentals and logic is essential to a career in the sector. Additionally, software engineers should have the capability to think critically and analytically about problems they need to solve by identifying patterns and adopting the divide-and-conquer paradigm.
A Software Engineer will generally look forward to be employed by a company or an IT service provider. Large organisations may have an in-house IT team and department. The profession is suitable for remote work, as in many cases employees or freelancers can perform their job without needing to be on site or at the office.
There is a great demand for software engineers; nonetheless, this can prove to be a quite competitive market when taking your first career steps in the sector and aiming to attain a high level of technical proficiency in a specific skill set.
Responsibilities
Software engineers are responsible for translating business requirements into technical solutions by designing, developing and packaging softwares.
Their key responsibilities are as follows:
Designing & Developing Application Software.Designing and developing application softwares using programming languages like Java, C++, TypeScript. This entails considering aspects such as: efficiency, scalability, maintainability, security, and user experience.
Documentation and Deployment.Documentation ensures that the software is understandable, maintainable and can be easily transferred to other developers. Deployment is the process of making the software available to end-users - it involves executing the source code that you have written.
Testing and Debugging.Thorough testing and debugging of software to find any issues in the code, and eventually troubleshoot and fix any errors that may arise.
CollaborationSoftware engineers rarely work on their own, as they are always in contact with other professionals to ensure the software meets the requirements and is delivered on time.
Maintenance and Updates.Software is not static but must be kept up-to-date and functioning optimally. This involves: bug fixes, security patches, feature enhancements, technical debt reduction.
Key skills & traits
Software Engineer must be able to the develop efficient and user-friendly software applications. Their key skills are the following:
Programming Languages and Frameworks.
Advanced proficiency in one or multiple programming languages (e.g. Java, Python, C++, C#, TypeScript) and frameworks (e.g. ASP.NET, Ruby on Rails, React, Next.js) is essential for software development.
Curiosity and Lifelong Learning.
A curious mind is important to keep up to date with the latest technologies on the market. This not simply is a matter of predisposition - it requires engineers to actively invest a significant amount of time in self-learning and experimentation.
Communication and Interpersonal Skills.
Software engineers should be able to express complex technical concepts clearly and concisely to team members, clients, and stakeholders. Although typically thought of as an analytical role, interpersonal skills should not be undervalued.
Data Structures and Algorithms.
A strong understanding of data structures and algorithms is crucial for efficient code design, including components, modules, and their interactions.
Problem Solving
Software engineers must be able to solve issues - both at the time of designing technical solutions (depending on the business requirements), and in response to development problems that may arise along the way.
Adaptability
While flexibly collaborating with diverse teams, software engineers must be able to adapt to changing requirements, emerging technologies and unforeseen challenges. Most importantly, given often ambiguous requirements or technical challenges, they must be able to break down complex problems, identify potential solutions, and make informed decisions.
Development Methodologies / Version Control
Familiarity with various software development methodologies (e.g. Agile, Waterfall) helps software engineers streamline projects and deliver high-quality work. On the other hand, version control systems, like GitLab, allow different software engineers to collaborate and track changes to code.
Analytical / Critical Thinking
Analytical and critical thinking are important skills for software engineers - they underpin the ability to design, develop, debug, and optimise software effectively.
Education & qualifications
When looking for a job as a software engineer, a university degree in a related subject (for example, Information Technology, Computer Science, or Software Engineering) generally is required. Any additional certification in IT, apprenticeship or internship experience can be beneficial to show that you possess knowledge of specific technologies.
A strong GitHub repository usually is a great indicator of a good software engineer. Like for any role, requirements may slightly vary between employers.

Career path
The career path of a software developer is not as rigid as you might expect. Software engineers may come from a different field of IT, being able to contribute their unique experience to the industry. Alternatively, they can be self-taught.
Junior Software Engineer
Entry to a junior position is likely to be from a BSc in Information Technology or in Software Engineering. However, some employers may hire candidates who hold A-levels in Coding, Maths, or Physics. Even for a junior position, it is likely that you will need to prove your coding ability in the relevant language.
Senior Software Engineer
Promotions will involve more responsibilities — for example, having more decision-making authority on architecture design, and conducting code reviews. A Software Engineer may specialise in any one of various different languages or frameworks. As a more senior Software Engineer, they may be well positioned to pick up freelance work.
Lead Software Engineer
Some teams will have a Lead Software Engineer, who spearheads the development team. The Lead Engineer will likely be less involved with coding in favour of other responsibilities - for example, acting as a point of contact for external stakeholders, answering technical or architectural questions and unblocking software engineers in their team.
Despite more focus on 'big picture,' a Lead Software Engineer may continue to take on various coding tasks - with many Lead Engineers continuing to leverage their expertise and take on the most complex coding tasks.

History of the profession
Being a software engineer is a relatively recent specialism. Although we can trace the concept of software to the 1940s, it is only since the 1980s that the job entered the mainstream - and only since the turn of the 21st century that it has exploded in popularity.
1940s - 1950s
The Birth of Software
Technology rapidly evolved in the wake of World War II, with the development of the first programmable electronic computers in this decade. Programming was done in machine code, with programs inputted manually using switches, cables, or punch cards.In the 1950s, the first high-level programming languages were born (including FORTRAN in 1957 and COBOL in 1959), which began to make programming more accessible and laid the foundation for software development.
1960s
NATO Software Engineering Conference
The term "software engineering" was coined at the 1968 NATO Software Engineering Conference, addressing the growing "software crisis" caused by inefficient development practices and unreliable software.
1970s - 1980s
Personal Computing and OOP
During the 70s and 80s the first microcomputers (for example, IBM PC and Apple II) were introduced. That meant for the first time, computers and their software were available in peoples homes - and software development became accessible for hobbyists.
Code was beginning to evolve into the programming languages we see today. In particular, Object Oriented Programming (OOP) gained prominence with languages like SmallTalk and C++ revolutionising how software engineers would think about reusable code.
For the first time, software also became something you could buy - with companies like Microsoft marketing software to the masses.
1990s
Rise of the Internet
The internet opened the door to rapid developments in software, and with it new specialisms, roles and opportunities for software engineers. Web browsers required new programming languages such as Java, PHP and JavaScript, and software engineers began creating web applications alongside traditional desktop software.During this time, open-source software also gained momentum, with projects like Linux demonstrating the power of collaborative, community-driven development.
2000s - Present
The Modern Era
By the turn of the 20th century, the Software Engineer was an established role within many companies. Technology has moved at unbelievable speed, opening up avenues and specialisms that could not have been conceived of a mere ten years before. They include mobile software engineering, with the launch of smartphones that connected to the internet; cloud computing, with platforms like AWS and Azure revolutionising how software is deployed and scaled; DevOps, an emerging field that merges development with operations and; AI and machine learning - the incorporation of intelligent algorithms for tasks ranging from search recommendation engines to autonomous vehicles.
