How to Get a Python Data Engineer Job

Data engineering is becoming a highly sought-after skill in the tech industry, with Python being one of the most popular programming languages used in this domain. As a Python programmer, the path to becoming a data engineer may seem daunting, but there are practical and actionable steps you can take to increase your chances of landing a Python data engineer job.

1. Basic Knowledge of Python

To begin with, you need a strong understanding of basic Python concepts, such as data types, loops, lists, and functions. Knowing a programming language is essential as data engineers use Python to clean and preprocess data, as well as to build required data pipelines.

In-depth knowledge of data structures and algorithms is also paramount. For instance, you should be familiar with various search algorithms, such as binary search and sorting algorithms, such as merge sort.

2. Develop Experience in Python Libraries Related to Data Science

There are a wealth of Python libraries to use with your coding projects. However, for data engineering, it is essential to have knowledge of certain libraries that are commonly used within the domain.

Some of the essential libraries you’d need to learn include:

  • Pandas: to read, modify, and extract data from various formats including CSV, Excel, and SQL databases.
  • Numpy: this is a library that helps in effectively managing large arrays of data.
  • Scikit-Learn: used in the creation of machine learning models along with deploying and training algorithms.
  • Matplotlib: helps create accurate visualizations that can easily aid in data story-telling.
  • SciPy: includes various routines to assist in data manipulation and signal/sound/image processing tasks.

3. Develop SQL and Relational Database Knowledge

In most organizations, data will be stored in structured storage. Therefore, you need to have knowledge of SQL databases to handle large volumes of data, and relational database concepts to understand how to manage and organize data into rows and columns.

4. Practice Building and Optimizing ETL Pipelines

Extract Transform Load (ETL) is a critical process in data engineering. Your role revolves around designing the right ETL pipelines that enable the organization to aggregate, transform, and store data within the database or data warehouse.

To succeed in this task, you need to practice creating ETL pipelines that can handle large volumes of data in varied formats. Ensure you follow the best practices in data management, which may include designing clear data transfer protocols as well as data pipelines that are built for reusability and scalability.

5. Participate in Data Science Projects

Getting involved in data science projects is a compelling way to enhance your data engineering skills. It not only boosts your knowledge, but it also helps you to gain hands-on experience in real-world data analysis scenarios. So start on your first data science projects by using publicly available data from sites like Kaggle.

6. Build a Strong Portfolio

To get your dream Python data engineering job, you need to have a strong portfolio that demonstrates your expertise and experience in the field. Your portfolio should include real-world projects that showcase your technical skills, problem-solving ability, and creativity.

7. Network with Data Experts

Networking with data science and data engineering experts in your domain can open new doors for you to get that dream Python data engineering job. It is essential to build relationships and attend data engineering meetups, allowing you to rub shoulders and learn new insights that can accelerate your knowledge in the field.


Although becoming a Python data engineer may seem daunting at first, taking small, actionable steps can propel you well on your journey. Broaden your knowledge in Python, acquire knowledge of core libraries commonly used in data engineering, gain hands-on experience by working through real-world data science projects, networking, and building a strong portfolio. These steps will set you apart from the pack and set you on the path to your dream Python data engineering job.
