What does a Data Scientist do? 

Fuelled by a growing amount of data availability and the progression of artificial intelligence, the demand for data science skills is rising exponentially.  A Data Scientist uses available data and develops complex models or Machine Learning algorithms to help businesses solve current and even future problems through data insights. 
They combine computer science, mathematics and business acumen to uncover results that are used to make objective business decisions. 

What skills does a Data Scientist need to have? 

The knowledge and skillset of a Data Scientist exceed data analyst skills because they are required to develop complex models to predict market trends and future behaviours. Therefore, the need to be able to develop and write code using a language such as R, Python or SAS is a must have. 
Data visualisation is the ability to present data driven insight in a user-friendly format that can be accessed by a variety of business stakeholders. An important asset for any Data Scientist, visual representations make it easier to identify patterns and trends. We recommend that candidates become familiar with interactive software such as Tableau, Pandas, MatplotLib, D3.js to succeed in this field. 
Machine learning is continuously evolving, and basic levels of the concept are quickly becoming a standard requirement for Data Science jobs. This is an extension of mathematics as linear algebra is the backbone of machine learning. 
A Data Scientist should be able to develop complex financial or operational models. This includes proficiency in algorithms such as regression, scenario analysis, modelling, simulation, clustering, neural networks, decision trees and beyond. 

What job description and responsibilities does a Data Scientist have? 

  • Collect, gather, analyse, and then visualise information to create insights that will drive business solutions 

  • Source additional information through the creation of new data and utilisation of any and all relevant statistical techniques, software packages, program languages and data infrastructure to resolve specific business issues 

  • Use predictive modelling to optimise business goals and outcomes 

  • Collaborate with other departments to develop and implement custom data models and algorithms 

  • Extract insights from data and communicate these effectively using appropriate technologies to stakeholders and other relevant parties 

  • Streamline and automate processes using artificial intelligence and machine learning 

What skills and experience do employers look for in Data Scientists? 

Degrees in computer science and mathematics are the most common among data scientists. Advanced computer science skills are essential as employers are leaning on data scientists to be both problem solvers and developers. In the rapidly developing discipline of machine learning, sophisticated algorithms are created to learn from the data. Applicants with comprehensive computer science skills will be looked at favourably by employers.
Mathematics is a significant component in any data science job as concepts within mathematics are critical in identifying patterns and creating algorithms. Calculus, linear algebra, and statistics are three topics that are regularly used in Data Scientist jobs. It is important to understand principles of calculus and how they might impact your modelling. 
Candidates who possess a genuine strength in probabilities and statistics will be in an advantageous position. Calculating the likelihood of an event is an intuitive concept that Data Scientists use daily when employing methods such as scenario analysis. In relation to statistics, you should be familiar with tree-based methods and competent in the application of validation techniques.
Business acumen relates to the knowledge and understanding of a particular field. Every industry has its own intricacies, and this should be recognised as an opportunity for you to gain a deep understanding of a particular field in order to stand out.  Learning industry intricacies is a gradual process that will be made easier if you can display strength in other fundamental areas such as computer science and mathematics. 
The value of communication as a Data Science skill should not be underestimated. These skills are important during the discovery and goal phase but are more prevalent in the presentation of results. Data Scientists are typically required to communicate their results to key stakeholders, including executives.
The ability to deliver results in a manner that is easy to understand, yet insightful and compelling, is where the value of a Data Scientist is exhibited. Employers are looking for Data Scientists who can tell them how the analysed data will impact their business.  


Data Science is an expanding field that is constantly evolving to meet technological advances and changing demands. The general route to a Data Scientist is to progress from a BI Analyst or Data Analyst Role with academic understanding of Data Science concepts.
Applicants with a background in computer science or mathematics can explore entry-level data analytics, business intelligence and data science jobs before progressing to a senior Data Scientist position. 

What qualifications do I need to apply for a Data Scientist job? 

Whilst you can get a Bachelor’s or Master’s degree in Data Science, a common academic path is qualifications in Computer Science, Maths, or Statistics. However proven relevant experience and a commitment to ongoing learning are essential.
