A software developer job description can vary depending on the organisation, technology and level of seniority, but most roles share some common requirements. Developers use code to create, test and maintain programs, systems and applications, working throughout the software development life cycle (SDLC).

Typical job descriptions will outline day-to-day software developer roles and responsibilities, the programming languages and technical skills required and any qualifications or experience employers expect. For security cleared software developer jobs, it may also specify the level of clearance required to work with sensitive systems or information.

What is a software developer?

A software developer is an expert in computer infrastructure and code. These experts utilise their proficiencies to create programs, systems and websites. In this position, you could work for a business, as an independent contractor or even in a research and development role, creating new code and fostering prospects in the industry.

What does a software developer do?

Software developers design, create, test and maintain software that enables people and organisations to perform tasks and deliver services. Their work can vary depending on the type of development they specialise in.

Front-end developers focus on the parts of websites or applications that users see and interact with, while back-end developers work on the underlying servers, databases and application logic. Full-stack developers operate across both areas.

The kinds of sectors software developers typically work in include:

  • Computer systems design
  • Manufacturing
  • Finance and insurance
  • Software publishing
  • Engineering
  • Aerospace and defence

Software developer and software engineer are sometimes used interchangeably, although engineering roles can place greater emphasis on the architecture and design of complete systems. Read our software engineer job description guide for a closer look at the role.

What skills should a software developer have?

If you’re looking for security cleared software developer roles, you’ll stand out as a strong candidate by demonstrating skills such as:

  • Coding and computer programming
  • Languages such as Java, Python, JavaScript or C#
  • Software testing
  • Software development
  • Object-oriented design (OOD)
  • Version control and source code management using tools such as Git
  • An understanding of the software development life cycle
  • Familiarity with Agile or Scrum development practices

Soft skills are equally important. Software developers usually work as part of a wider technical team, making communication, collaboration and problem-solving valuable attributes.

It’s also a career that demands strong attention to detail. Developers must be precise when writing and testing code, particularly when working on highly classified systems and information where mistakes or inappropriate handling of data could have security implications.

What is it like to be a software developer?

The day-to-day work of a software developer varies according to the project and organisation, but coding is only one part of the role. According to the National Careers Service, typical software developer job duties can include:

  • Discussing requirements and development ideas with clients or stakeholders
  • Working with technical teams to create plans and timescales
  • Writing and updating code
  • Testing software at different stages to identify and fix bugs
  • Checking that software meets relevant quality standards
  • Recording and documenting changes throughout development
  • Completing checks before releasing software
  • Maintaining and supporting live systems

Developers may also participate in team meetings, code reviews and planning sessions and work alongside testers, designers, engineers and other technical specialists.

What are the career development opportunities for a software developer?

A software developer career path can take several directions depending on your skills and interests. At junior or entry level, you’ll typically work under supervision while developing your coding skills and gaining experience of real projects.

With experience, you can progress into a senior software developer position, where you may lead a team, mentor junior colleagues and take greater responsibility for technical decisions.

Further progression can lead to positions such as technical architect, with responsibility for the design of complex systems. Developers can also specialise in related areas such as systems design, IT architecture or business systems analysis.

Other routes include moving into development or project management, setting up your own company or working independently as a consultant. At larger organisations, experienced technology professionals may eventually progress into director or chief technology officer positions.

Working hours and environment

Software developers typically work around 37 to 40 hours a week, although occasional evening or weekend work may be necessary. Developers can work in offices, remotely, from home or at client premises, making hybrid and remote arrangements possible for many roles.

However, security cleared software developer jobs can operate differently. Projects involving classified information or sensitive systems may require developers to work on secure sites or within restricted environments where systems cannot be accessed remotely. Some development environments may also be isolated or air-gapped from public networks. Always check the individual vacancy for working-location and security requirements.

How do you become a software developer?

A university degree is one route into software development, but it isn’t the only option. Practical coding ability and demonstrable experience can also be valuable to employers.

Building a portfolio is a useful way to showcase your skills. Personal projects, open-source contributions and hackathons can demonstrate how you apply your technical knowledge to real problems.

There are also several formal non-degree or work-based routes. These options include:

  • T Level in Digital Software Development
  • Software Development Technician Level 3 Advanced Apprenticeship
  • Software Developer Level 4 Higher Apprenticeship
  • DevOps Engineer Level 4 Higher Apprenticeship
  • Digital and Technology Solutions Professional Level 6 Degree Apprenticeship

Starting in a junior position can also give you the opportunity to build software developer skills through practical experience while learning from more senior colleagues. Resources and professional development from organisations such as BCS, The Chartered Institute for IT, can help you continue developing your technical knowledge throughout your career.

What is a software developer’s salary?

A software developer salary in the UK varies according to experience, location, technical specialism and employer. The National Careers Service currently gives a broad pay scale of approximately £30,000 for starters to £75,000 for experienced software developers.

Within that overall range, salaries generally increase as developers gain experience and take on greater responsibility:

  • Junior and entry-level developers: salaries commonly begin around the £30,000 mark, although individual vacancies may pay less or more.
  • Mid-level developers: earnings typically rise as developers become able to deliver projects more independently and develop specialist technical skills.
  • Senior software developers: salaries can move towards the upper end of the £75,000 National Careers Service range and may exceed it for highly specialised or leadership positions.

Security clearance, specialist programming knowledge and experience working on sensitive or complex projects can also affect individual offers.

Do you need a degree to be a software developer?

Although a degree in computer science, software development or another related subject remains a common route into the profession, it isn’t an essential requirement for every software developer job.

The National Careers Service lists college courses, apprenticeships and graduate training schemes alongside university study as routes into the profession. It also notes that developers can build their knowledge through online resources covering programming languages, project management and software development methods.

Whichever route you choose, being able to demonstrate your software developer skills through practical work, projects or a portfolio can help strengthen your application.
