What is data engineering?
Data engineering is a crucial field that involves data analysis, computer science, and software engineering. Data engineers create, implement, and maintain the infrastructure, systems, and pipelines necessary to process and transform large sets of data. Think of a data engineer as the architect and builder behind the scenes, ensuring that data is captured, stored, and accessible for analysis and insights.
What does a data engineer do?
Data engineers work closely with data scientists and data analysts to understand their requirements and translate them into scalable data solutions. They are responsible for building data pipelines, integrating various data sources, cleaning and transforming raw data, and optimising the data warehousing and retrieval processes. In essence, they create the framework that enables organisations to derive valuable insights from their data.
The role of a data engineer can vary depending on the organisation and industry they work in. However, some common responsibilities include:
Building and maintaining data pipelines
Data engineers are experts at designing and implementing data pipelines that efficiently process and transform data, using tools and technologies such as Apache Spark and SQL to ensure smooth data flow.
Integrating data sources
A skilled data engineer is an expert at integrating different data sources, including data warehouses, APIs, and data streaming systems to ensure the integrity and reliability of the data being collected.
Cleaning and transforming data
Data engineers are responsible for cleaning and transforming raw data into a usable format. They apply techniques like data normalisation, aggregation, and quality control to ensure data accuracy.
Data storage and retrieval
Data engineers optimise data storage and retrieval processes so that analysts and data scientists can efficiently access and retrieve the required information. They often implement database management through data warehouses and cloud storage solutions.
Troubleshooting and performance tuning
Troubleshooting and performance tuning are key responsibilities of a data engineer as it ensures smooth data operations, empowers timely and reliable data analysis, and supports organisations in making informed decisions based on high-quality data.
Collaboration with data teams
Data engineers collaborate closely with data scientists, data analysts, and other specialists to provide them with the infrastructure and tools they need to analyse data. This collaboration drives data-informed decision-making in organisations.
How to become a data engineer
If you're interested in a career in data engineering, here are the steps you can take to get started:
1. Education and qualifications
A strong foundation in computer science, information systems, or a related field is beneficial if you're looking to pursue a future career as a data engineer.
Most employers typically look for role candidates who are educated to a degree-level, as it shows that you have a strong foundation in data engineering skills and data tools.
2. Gain technical skills
Data engineering requires a strong knowledge of programming languages such as Python, Java, or Scala. You'll also want to familiarise yourself with database systems, SQL, big data processing frameworks, and cloud computing platforms like AWS or Azure.
If you're looking for a degree to develop your data engineer skills, explore the modules on offer to make sure you can develop proficiency in these systems and platforms.
3. Hands-on experience
Build your portfolio by working on practical projects that involve data management, integration, and analysis. Open-source projects are often available online and are an invaluable way to get practical experience while also giving you the opportunity to network with other data engineers.
If you want more structure than an open-source project provides, internships and placements are a great way to get a feel of what it's like to be in a data engineering job. At LIBF, all our degrees come with optional internship modules, so you can put your learning to practice while being part of a team.
4. Continuous learning
In a rapidly evolving field, it's important stay up-to-date with the latest technologies, tools, and data trends. Many data engineers follow industry publications, blogs, and websites to stay informed about the latest advancements and best practices in the field.
By embracing continuous learning, aspiring data engineers can expand their expertise, enhance their problem-solving abilities, and remain competitive in the job market.
5. Professional networking
Connect with professionals in the data engineering field through networking events, industry conferences, or online communities. Joining professional associations or LinkedIn groups can also provide opportunities to connect with experts and senior data engineers to learn from their experiences.
Networking can open doors to mentorships, job opportunities, and valuable insights about the industry. Engaging with professionals already working as data engineers can provide you with guidance, advice, and access to resources that can accelerate your career in data engineering.
