custom swim caps New ways into the lucrative world of data science

November 05, 2021

What is a data scientist? The job title sprang out of nowhere as technology firms have scrambled to find people to perform sophisticated analytical tasks over the last decade.

Reports of six-figure salaries abounded as businesses competed for staff to slice and dice data in pursuit of business lessons and emerging trends.

Recruitment firm PageGroup cites annual salaries for data science work of between £60,000-150,000, while cautioning that the job title covers a huge range of disciplines and responsibilities.

The line has become blurred between data science and other tasks such as data analysis. James Hobson, a technology specialist at PageGroup notes that "there are different interpretations of what constitutes a data scientist".

Whatever the title, demand for staff has outstripped the supply of those traditionally considered suitable to the work, usually candidates with doctorates in computer science.

A 2020 report into emerging jobs in the US by LinkedIn estimated that data science vacancies were growing at 37% a year.

So new entrants are coming into the field from unorthodox routes, aided by new software packages. Edward Green and Balraj Oates are two of those, although they both hesitate over the data scientist label.

For Mr Green, his data science journey began at 15 when he embarked on series of extended stays in London's Great Ormond Street Hospital while being treated for a complex medical problem that required three bouts of surgery over two and a half years.

Most of us would prefer to forget such an ordeal. But Mr Green remembers it as his gateway to a career working with technology. "The day I had my first surgery was the day the iPad was released," he says.

He joined the hospital's patient council and began capturing medical data on an iPad so it could be displayed to patients. This experiment saw him head straight into IT from school.

His surgeon had worked with McLaren, studying the application of F1 pit stop techniques to the movement of patients in and out of intensive care. So motor racing - and work at McLaren's technology centre just outside London where data from cars are analysed - was his next step.

At McLaren he uses data science software from US firm Alteryx that has developed its own self-service tool which can help people to become data experts.

For Mr Green, it trained him to juggle vast quantities of data. In McLaren's case that means 1.5 terabytes worth collected from every race. "Sometimes the drivers feel they don't need this data, but they do," he says.
