13 Data Science Careers That Are Exploding Now

Data science is one of the fastest growing and most in-demand careers today. Learning skills in this area is an exciting way to grow or change your career.

Data scientists are needed across many industries. Job openings are surging because businesses are producing useful data in expanding volumes. Experts are hired to accomplish tasks such as to predict market trends, boost sales conversion rates and chart business development.

What exactly do data scientists do?

Data scientists analyse information. They take a multidisciplinary perspective, drawing from areas such as programming, machine learning, statistics, software engineering, human behaviour analysis, linear algebra, experimental science and data intuition. Data scientists solve problems and find new insights into how an objective can be achieved.

“Data is the new oil” said Clive Humby, a renowned mathematician. In a world where 2.5 quintillion bytes of data are created each day, it’s no surprise why data science jobs are in the new hot commodity.

After asking questions related to a fundamental problem, data scientists will work with raw data, collecting, organising and analysing it. They create and use algorithms for the identification of patterns and trends in the work of answering questions.

Then, after answering the questions at hand, data scientists use the analysed data to create visualisations. This is an important part of task of presenting data analysis and findings. Insights must be shown in a way that is accessible for colleagues who aren't trained or knowledgeable in technology.

Is data science right for you?

Successful data scientists have aptitude in the fields of maths, programming and statistics. Data scientists collect information and data, sorting and analysing it. They use different kinds of data sources when problem-solving and addressing questions. Heard of algorithms? You'd be creating these as a data scientist.

You’ll use statistics in your analysis and employ complex concepts, including data visualisation and machine learning. If you enjoy identifying patterns and trends, data science may well be the perfect field for you.

Combining computer science, modeling, statistics, analytics, and math skills—along with sound business sense—data scientists uncover the answers to major questions that help organizations make objective decisions.

Computer programming, AI, and even areas such as human behaviour are fields where proficiency will be key to your success as a data scientist. If you have a curious mind and are a keen problem-solver, data science is certainly a field you may want to train for.

Perhaps it will surprise you that creativity is also an important part of this scientific field. Keeping an open mind and being willing to follow your instincts (after education and training, of course) are key.

1. Data Scientist

Most highly trained data science professionals call themselves a data scientist or similar. The job is to take large amounts of data and transform that into insights on which a business or organisation can take useful action. A data scientist is an extremely important addition to a company. This professional provides the information needed for a business or organisation to make decisions.

Data scientists are employed across many industries, including large companies and government agencies. There is huge demand for these professionals. So you should find the job search process less challenging than in many other careers, especially if you are even more highly skilled than your competitors.

As a data scientist, you examine data to achieve insights and present these insights to other professionals. This must be done in a way that people without a technical background can understand. Data scientists need to have skills in areas such as computer science, analytics, statistics, modelling and maths. Depending on your organisation and its goals, you may also need a reasonable or high degree of business knowledge and sense.

The position of data scientist is usually ranked a bit higher than that of data analyst. For example, a data scientist may create a complex data model that a data analyst may then use on a daily basis to produce business reports. Data scientists are usually fluent in programming languages such as SQL, Python and R.

A data scientist designs processes for data modelling. These processes are needed to create predictive models and algorithms, as well as custom analysis. This professional must work with business stakeholders and reach conclusions about how data should be utilised to reach objectives and goals.
