Applications developer

Applications developers make computers perform specific tasks, based on their client's specifications

As an applications developer, you'll translate software requirements into workable programming code and maintain and develop programs for use in business.

You'll usually work within a specific development field, such as mobile phone applications, accounting software, office suites or graphics software, and will have expert knowledge of at least one programming language.

The work of an applications developer differs from that of a systems developer, in that systems software enables the computer to operate, whereas users interface with the applications software that runs on top of it.

In this role, you may also be known as an app developer or mobile app developer.

Types of applications developer

You might write applications, or apps, for either:

• a particular system, such as Windows or Android
• across multiple platforms, including desktop and mobile devices.

These may be developed as commercial products or tailored solutions for individual clients.

Responsibilities

As an applications developer, you'll need to:

• establish a detailed program specification through discussion with clients
• clarify the actions the program is intended to perform
• write the program by breaking down program specification into its simplest elements and translating this logic into a programming language
• work as part of a team, which may be formed specifically for a project to develop a particular part of the program
• test sample datasets to check that program outputs function as intended
• install the program into production, once testing is complete
• devise possible solutions to anticipated problems
• respond to problems and make necessary corrections
• evaluate and enhance the program's effectiveness
• adapt the program to meet changing requirements
• conduct user acceptance testing, to ensure the program is intuitive, efficient and accurate
• write detailed documentation for the operation of the program by users and computer operators
• consult manuals, periodicals and technical reports to learn new ways to develop programs and maintain existing skills and knowledge
• update, repair, modify and develop existing software and generic applications.

Salary

• Graduate salaries for applications developers start at around £25,000.
• Once established, you can expect to earn in the region of £35,000 to £40,000.
• Senior applications developer salaries range from £45,000 to £70,000.

Salaries vary according to the type of application developed, the location, size, and nature of the employer's business and the sector. Top-range salaries are mostly found in the finance and consultancy sectors based in London and the South East.

Contracting rates of pay are around double the rates permanent staff receive.

Income figures are intended as a guide only.

Working hours

Working hours are typically 9am to 5pm, but overtime, including evenings and weekends, is common when meeting deadlines.

Career breaks and part-time work are possible, and some IT employers offer flexible working hours.

What to expect

• Most applications developers work in an office environment in one location, although remote working is also common.
• You'll spend long periods in front of a computer terminal.
• Self-employment through contracting is possible with experience.
• At present, men considerably outnumber women in the IT workforce, but steps are being taken to redress the balance, with initiatives such as Code First: Girls, Rails Girls, GeekGirlMeetup and the Women in IT Awards.
• Travel within a working day, absence from home overnight and overseas travel may be occasionally required. There's more travel involved in installation and implementation work.

Qualifications

You'll be expected to have a good level of technical knowledge and many employers, particularly software houses, will want you to have a degree in a relevant subject, such as:

• business and management
• computer science or software engineering
• information systems
• mathematics
• physical, mathematical or applied science.

If you don't have a related degree, you could complete an IT conversion course to build up evidence of technical ability.

In some instances, there may be opportunities to enter this career without a relevant degree or diploma, but you'll need to demonstrate your commitment and interest to IT applications and be able to show that you have technical skills.

Search postgraduate courses in computer science and IT.

Skills

You'll need to have:

• a strong maths ability for understanding and writing programs
• high-level programming and related technical skills
• ingenuity and creativity
• a logical approach to problem solving
• analytical capabilities
• the ability to work well under pressure
• experience of development methodologies, such as the Waterfall model and Agile
• attention to detail
• tenacity and patience
• communication skills, including the ability to convey information to non-technical colleagues concisely
• an understanding of business processes and constraints.

Work experience

Familiarity with computers and standard software is essential and relevant work experience is desirable. This could be in the form of a placement year as part of your degree, or part-time work within an IT field.

You could also try to get involved in projects at university or with local businesses or charities, which will require you to develop programs and code and have knowledge of computer language.

Employers

Opportunities exist for new graduates in all employment sectors, including:

• financial services
• health
• retail
• travel and tourism.

Many financial institutions, management consultancies and major retailers offer specific IT graduate-training programmes.

IT companies themselves have large IT departments to manage their own systems, and they also run IT systems for other companies on a consultancy basis. Employers can be large multinational corporations, medium-sized companies or small software consultancies employing only a few staff.

Employment can be found across a range of business sectors, including finance, the public sector and education sector. You'll often work as part of a team with other IT professionals, such as software engineers and testers and systems analysts, and write programs according to their specifications.

Look for job vacancies at:

• Contractor UK
• CWJobs
• Technojobs
• Unicorn Hunt
• Women in Tech

There's a high demand for talented candidates and strong competition for highly sought-after posts. The selection process is frequently made up of presentations, group exercises, psychometric tests and in-tray exercises.

You may be asked to submit a demo, particularly for entry into the games industry.

Many organisations advertise their vacancies on their own websites and welcome speculative applications.

Professional development

Since there are continual developments in the IT industry, it's important that you update your knowledge and skills regularly. One way to do this is by taking courses sponsored by your employer or provided by software vendors.

Some larger employers offer structured graduate programmes where you'll gain experience in several team-related projects in different work areas.

Most companies offer ongoing training, either in-house or via external courses, but if you're self-employed, or employed by a smaller employer, you may need to consider the cost and time implications of taking responsibility for your own training.

When recruiting, employers often ask for vendor certification, as this provides confirmation that someone is competent in specific skills. Certification is awarded by product vendors and software firms in recognition that an individual has obtained the relevant skills and knowledge to work with particular languages, applications and operating systems.

Other professional qualifications are available through BCS - The Chartered Institute for IT. The institute also provides information and guidance about career planning and developing expertise.

You can find further information about relevant qualifications, and the identification of skills, from the Institution of Analysts and Programmers (IAP) and the SFIA Foundation.

Career prospects

Many graduates start with programming roles, which provide a strong foundation for careers in systems analysis or systems design.

In large organisations, you may progress to a senior applications developer role with supervisory responsibilities. With more business experience, you could move into systems analysis or an applications manager position. You might also specialise in either management or contracting. Alternatively, you could develop your expertise in a particular application area, such as databases, or a programming language like Java or C++. While specialisation can be limiting, it may suit you if you want to become an expert in a niche area.

You could also move into project management, taking on a broader role overseeing teams of developers and the overall design and implementation of software projects.

Another option is to work as a self-employed contractor, acting as a systems developer -discussing user needs, analysing requirements, and writing and implementing programs.
