In a world where ever-growing sources of business data become increasingly critical to maintaining competitive advantage, organisations are relying heavily on data to make decisions. There are now numerous data-specific roles across industries, but many people have misconceptions about them, particularly when it comes to understanding the differences between similar sounding roles like Data Analyst and Data Engineer, for example.
For senior leaders tasked with the digital transformation of their organisation, understanding what these roles do and having clarity of the skills required for each role is key to hiring success.
Here we’ll consider the difference between Data Analysts and Data Engineers. The two roles work on different business priorities and require distinct skillsets. In this article, we’ll look at the job descriptions, organisational roles, required skill sets, and salary expectations for each of these exciting data careers.
In simple terms, a Data Analyst's mission is to comb through data and make it understandable. They transform what appears to be an incomprehensible tangled mess of numbers into actionable insights, in order for teams and organisations to reach decisions.
A Data Analyst holds an entry-level position on a data analytics team. Data Analysts need to be skilled at converting numerical data into a format that everyone in an organisation can understand. They must be proficient in a variety of areas, including programming languages such as Python, tools such as Power BI, and the fundamentals of data processing, reporting, and modelling. With enough experience, a Data Analyst can gradually advance to become a Data Scientist.

The backgrounds of Data Analysts vary greatly. A Data Analyst would traditionally have been someone with a bachelor's or master's degree in maths or computer science. The contemporary Data Analyst, can have a background from almost any field, however they still tend to come from a role which involves some quantitative element. The education needed to become a Data Analyst isn’t stringent, as the capacity to work with and understand data is much more important.

A Data Engineer’s job is to build and maintain data architecture which ensures the creation of good quality data that can be used by the rest of the organisation. They are experts in the preparation of large datasets for use by Data Analysts. Where a Data Analyst must interpret data, an engineer must create programmes that can generate data into a meaningful configuration, such as making sure the format of the data is what the Analytics team requires. Data Engineers build the data warehouses, data pipelines, and databases that Data Analysts and data scientists use to access and manipulate data.
If we consider data as a tool, imagine that a Data Engineer is the person in charge of the factory, ensuring that all of the equipment is neatly organised so that everyone can locate the specific tool they require.
Working with both structured and unstructured data is essential for a Data Engineer. As a result, SQL expertise is a critical requirement. A Data Engineer must also perform tasks such as data deduplication, data management, and data cleaning. Like Data Analysts, Data Engineers need to have strong programming skills and an understanding of algorithms. Creating an API, for example, or building a cloud infrastructure could be among their responsibilities. Where a Data Analyst’s role is primarily analytical, a Data Engineer’s role is a highly technical function that necessitates extensive knowledge of engineering and testing tools.

If you've made it this far, you're probably wondering which role commands the highest salary. As with any job, a variety of factors such as geographical location, level of experience, company, and job role influence how much a Data Analyst or Data Engineer can expect to earn.
At the time of writing, according to Indeed.co.uk, the average base salary for a Data Engineer is £60,084 per year in the United Kingdom. Comparatively, the average base salary for a Data Analyst is £34,100 per year.
But keep in mind that these are merely averages, and factors such as breadth of knowledge, brand name, company size, profile, and location can cause a significant difference in salary between a Data Analyst and a Data Engineer.
If poor data quality is a current pain point in your organisation, it might be caused by a lack of data engineering talent to build and maintain the data pipelines.
If your organisation has lots of data being produced but is struggling to inform decision-making with that data, then data analysts can solve this gap.
However, it’s important to note that any data-driven organisation will need both roles - the success of the analytics team is dependent on data engineering. The work of the data engineering team to produce quality data is maximised by a strong analytics team.
