What is a career in data?

The data sector is extremely dynamic, quickly evolving, and impacting and shaping many aspects of the world we live in. Large datasets have become available in the last decade, enabling the development and growth of a wide range of uses and applications, for example in generative AI, cloud computing platforms, big data tools (such as Spark and Hadoop), IoT (Internet of Things), speech and face recognition, or autonomous vehicles.

  • Data analytics entails examining large data sets to discover meaningful patterns, extract insights and identify trends. Using specialised tools and techniques, data analysts transform raw data into visualisations like charts and dashboards. The goal is to present these findings through strong written and verbal communication, enabling businesses to make informed strategic decisions.
  • Data science is an interdisciplinary field focused on extracting knowledge and insights from structured and unstructured data. It involves the use of analytics, algorithms, machine learning and statistical tools to build predictive models. A data scientist combines technical, analytical and communication skills to make sense of data and help businesses make strategic decisions.
  • AI Development is the broad science of creating intelligent machines that can simulate human thinking and behaviour, such as learning and problem-solving. The field is typically divided into narrow AI, which performs a single task, and general AI, which is a theoretical concept of machines with human-like cognitive abilities. Careers in AI are diverse and often highly specialised, requiring a strong foundation in mathematics, computer science and statistics.
  • AI ethics and responsible AI encompasses topics like data privacy, algorithmic bias and the responsible development of AI systems. The increasing use of data and AI has brought ethical considerations to the fore, leading to a growing need for professionals who understand the social and ethical implications of AI-related work. 
  • Data governance and data security professionals ensure data quality, compliance with regulations like GDPR (General Data Protection Regulation), and the security of sensitive information. With the massive growth of data, organisations are placing a huge emphasis on how data is managed, stored and protected. 
  • Machine learning is a branch of artificial intelligence to create programmes and algorithms that enable computer systems to continue learning and improving on their own, based on data and experience, pattern identifications, and to taking actions without direct instruction. It utilises data to improve performance andor inform predictions.
  • Natural language processing (NLP) is a branch of AI that focuses on enabling computers to understand, interpret and generate human language. This skill is critical for developing chatbots, virtual assistants and sentiment analysis tools.

The data sector provides a range of dynamic and innovative working environments and the opportunity to develop sought-after skills and knowledge. It is a real asset to have some technical skills and a genuine interest in technology. However, employers also recruit graduates with no prior technology or coding skills or degree.

For technical roles, you would need to prove you are willing to learn quickly and take part in training and development (often comprising a combination of in-house provision, external certifications and online courses). More and more organisations are accepting applications from graduates across all academic disciplines for roles within data and IT, opening up new career paths for LSE students with a passion for technology and analytics.

The growing trend for both private and public sector organisations to apply data analytics to business decision making is also a key influencer on graduate labour market trends. With the adoption of new technologies, highly analytical graduates with strong quantitative skills, are actively sought by employers. Transferable skills and attributes such as problem solving, communication and teamwork, eagerness to learn, and business acumen are critical and will be assessed in the recruitment process.
