If you’re looking to pursue a career in IT as a software engineer, understanding what the role involves is an important place to start.

A typical software engineer job description will outline the key responsibilities, required technical and soft skills, qualifications and experience. While exact requirements vary between employers, knowing what companies commonly look for can help you decide whether this career is right for you and prepare for your software engineer job search.

What does a software engineer do?

A software engineer develops and maintains software and applications. They use programming languages, platforms and architectures to build, test and improve computer software.

These professionals are highly analytical and apply their knowledge of engineering principles and programming languages throughout the software development life cycle (SDLC) to improve software and increase productivity.

Alternatively, a software engineer may work as a consultant or independent contractor, while some take on research-based roles in which they develop new code and help train more junior employees.

The terms software engineer and software developer are sometimes used interchangeably. However, software engineering can place greater emphasis on applying engineering principles to the design and development of complete systems, while a software developer may focus more specifically on creating software and applications.

What is typical of a software engineer job description?

Software engineer jobs look different depending on the organisation, but it’s worth understanding what a typical job description will look like. This includes software engineer duties and responsibilities, your ability to work at problem solving and the qualifications that tend to be expected.

Roles and responsibilities

As a software engineer, there are many roles and responsibilities that almost any organisation will expect and include in their job description. These could be:

  • Developing software and implementing scalable solutions
  • Taking responsibility for the SDLC, including designing, testing and upgrading software
  • Writing and testing code
  • Meeting user requirements
  • Creating scripts that transform data to meet business objectives
  • Writing scripts to support the automation of processes
  • Using version control and source code management systems to manage, integrate and merge code from multiple contributors
  • Maintaining and monitoring live systems and implementing software updates and patches to resolve issues
  • Writing technical specifications and documentation, often in collaboration with other technical specialists
  • Keeping up to date with the latest technologies
  • Constantly seeking out new learning opportunities

The exact responsibilities will depend on the employer, project and level of seniority. An entry-level software engineer job description, for example, is likely to involve more supervised development and testing, while a senior software engineer job description may include architectural decisions, mentoring and responsibility for larger projects or teams.

Skills expected from a software engineer

Additionally, certain soft and hard skills facilitate the role of a software engineer. You can expect a typical job description to demand evidence of the following capabilities:

  • Proficiency in several programming languages, such as Java, C++, C# or Python
  • Analyse large volumes of data and complex technical information
  • Building software applications
  • Experience working with version control repositories and source code management
  • Manage several projects simultaneously
  • Excellent problem-solving skills
  • Explain complex technical issues clearly to non-technical colleagues, clients and stakeholders
  • A meticulous and organised approach to work
  • Work effectively both independently and as part of a wider development team

Software engineer requirements can differ slightly in security cleared environments. Engineers working on sensitive or classified projects may have restrictions on the systems, information and external resources they can access. This can mean they cannot rely on public forums, code repositories or open collaboration in the same way as engineers working on unrestricted commercial projects. Being able to solve problems independently and work within strict security procedures can therefore be particularly valuable for security cleared software engineer roles.

Qualifications and training

The software engineer job description will also outline the qualifications you’ll be expected to have in order to apply. Common requirements include:

  • A degree in a science, technology, engineering or mathematics (STEM) subject
  • A master’s-level qualification for some senior software engineer jobs
  • Applicants with degrees in non-STEM subjects of at least 2:2 may sometimes be accepted, particularly where the rest of their CV demonstrates strong technical skills and relevant experience
  • Training in common programming languages such as Java, C++, C# and Python

However, a university degree isn’t the only route into software engineering. College courses, apprenticeships and graduate training schemes are all potential ways to get a career in software development.

A foundation degree or Higher National Diploma (HND) in an area such as computer science, IT or software development can also help you enter the profession. Software engineering degree apprenticeships allow candidates to combine academic study with practical workplace experience.

It may also be possible to progress into software engineering from related technical positions, particularly if you can demonstrate coding ability and practical project experience.

Once you’re working in the industry, ongoing professional development is important. The British Computer Society, The Chartered Institute for IT, offers professional certifications across areas including solution development, architecture, software testing and DevOps that can support continued career development.

Which sectors employ software engineers?

Many sectors require software engineers, not just software development companies. Choosing one where you also need security clearance can help narrow down the field, meaning your security credentials could improve your chances of being offered an interview.

Sectors to look into include:

  • Technology consultancies
  • Telecommunications firms
  • Banks and financial services businesses
  • Public sector organisations

These industries often deal with sensitive information and confidential projects that require a high level of discretion. They do still need the skills and experience of a software engineer who can carry out their duties and responsibilities professionally.

Starting your software engineer job search in areas where you can put your security clearance to good use could make all the difference to your career. Combine this with your technical and soft skills and you’ll be a well-rounded candidate

Working hours and environment

Software engineers commonly work standard office hours, at around 37 to 40 hours per week, although occasional evening or weekend work may be required. Hours can increase around important project deadlines, software releases or when urgent problems need to be resolved.

Because much of the job is computer-based, software development can lend itself to remote and hybrid working. However, this may not always be possible for software engineers working in security cleared roles. Some sensitive projects require engineers to work from secure sites or use restricted systems and networks that cannot be accessed remotely. 

Career progression for software engineers

A typical software engineer career path begins in an entry-level or junior position, where you’ll usually work under the supervision of more experienced engineers while developing your technical skills.

With around three years of experience, you may progress into a mid-level position with greater responsibility for developing solutions and producing detailed specifications independently. After five or more years, opportunities can include senior software engineer positions where you may supervise team members, mentor junior engineers and take greater ownership of technical decisions.

From there, progression can take several forms. You could move into engineering or development management, become a technical architect or consultant or specialise in a particular programming language, technology or platform.

Experience requirements differ considerably between employers, so these timeframes should be treated as general guidance rather than fixed milestones. If you’re looking to progress your career, explore the latest senior software engineer jobs on SecurityClearedJobs.com.

How much can you earn as a software engineer?

How much a software engineer earns depends on factors including experience, employer, technical specialism and location. The National Careers Service currently puts the broad salary range for software developers at approximately £30,000 for starters to £100,000 for experienced professionals.

Within the wider software engineering market, salary bands can extend beyond this range, particularly for senior and highly specialised positions. As a general guide, current UK market data suggests:

  • Entry-level and junior software engineers: around £30,000 to £45,000
  • Mid-level engineers with around three to five years’ experience: approximately £50,000 to £70,000
  • Senior software engineers with five or more years’ experience: around £60,000 to £95,000
  • Lead, staff and principal engineers: salaries can rise beyond £85,000, with some specialist and London-based positions exceeding £100,000

These figures should be treated as broad market ranges rather than guaranteed salaries. Location can have a significant effect on pay, especially for software engineers in London. Security clearance, specialist technical skills and experience working on sensitive projects may also influence the salary offered for individual vacancies.
