What is Data Engineering?

Data Engineering refers to the building and maintenance of computer systems to collect, store and analyse data. The job description of a Data Engineer combines elements of both Software Engineering and Data Science.

Data Science vs Data Engineering

The roles of a Data Scientist and a Data Engineer are similar and there is an overlap in skills, however, the roles are not the same. Data Engineers build the programmes that process data and deliver this to the Data Scientists in the appropriate format, a Data Scientist will then clean and analyse the data.

Types of Data Engineers

1. Big Data Engineer – an IT professional who works with large data sets to build and maintain complex processing systems.
2. Data Architect – is responsible for dealing with the policies and procedures associated with data handling within an organisation.
3. Data Analyst – is tasked with analysing data to identify patterns and insights that will benefit the business.
4. Machine Learning Engineer – work as part of a team to design and build AI algorithms and programmes.
5. Data Scientist – is responsible for analysing data to draw actionable insights, identify opportunities and solve problems.
6. Software Engineer– an expert in programming languages whose role is to design and develop computer systems and applications.
7. Data Programmer – builds database programmes, carrying out troubleshooting and updating systems based on business and user requirements.
8. Data Warehousing Engineer – develops and manages data warehouse systems and strategies.
9. Cloud Engineer – designs and implements cloud-based systems, ensuing cloud systems meet organisational requirements,

Data Engineering job description

A Data Engineer is responsible for designing, building and maintaining systems for data collection, storage and analysis. Their main goal is to create data sets that are high-quality, reliable and can be interpreted; they do this using a combination of different raw data sets. The key roles and responsibilities of a data engineer include:

• Understanding business requirements and creating systems to meet business needs
• Analysing raw data and transforming it into efficient data systems
• Building and maintaining data systems and data pipelines
• Improving data quality and reliability
• Formatting data for prescriptive and predictive modelling
• Developing analytical tools and programmes
• Collaborating with Data Scientists to analyse data and identify trends

What skills do Data Engineers need?

The skills and knowledge required to work as a Data Engineer will vary depending on your company, but here is a breakdown of some of the essential skills required for a Data Engineer:
