What to consider when hiring a Python Developer?
Definition of Python
Why is Python one of the greatest programming languages out there?
You nearly have an endless way to shape the results like building websites and diverse software, automate tasks, and conduct data analysis.
Python is known as an interpreted, object-oriented, high-level programming language. People use it for Rapid Application Development based on the great amount of modules and packages that lead to increased productivity.

Types of Python Developers
Reading through this chapter will help you to identify the most important skills when creating a Python Developer job description going forward or to scan through CVs of possible candidates.
Python Back End Development
Backend Python Developers are responsible for developing and maintaining the components on the server-side of web apps to support the Frontend to function optimally. They are working with several frameworks, databases, and APIs, though these tools and technologies may vary greatly depending on the project requirements.
Object-Relational Mapping (ORM) refers to a method of retrieving and modifying data from a database using an object-oriented approach. Typically, when discussing ORM, people are referring to a specific library that implements this technique, which is commonly referred to as “an ORM”.
Python Data Engineer
A Python Data Engineer builds, maintains, and optimizes data streams and infrastructure. Core tasks are to extract, transform data from several sources into storages, like data warehouses or data lakes. Data quality and consistency plays an important role, additionally to shaping the right workflows to process data. In collaboration with data analysts and data scientists they aim to develop solutions that enable effective data analysis and reporting.
- NumPy, Pandas as data manipulation libraries
- Knowledge and experience in working with databases like MySQL, Oracle and PostgreSQL
- A deeper understanding of Data Warehouses using technologies like Apache Hadoop or Apache Spark
- Apache NiFi, Talend, and Apache Kafka and experience in designing and implementing ETL (Extract, Transform, and Load) pipelines
- Understanding of cloud infrastructure like AWS, Azure, or Google Cloud including Services like S3, EC2, and EMR
Python AI Engineer
A Python AI Engineer is responsible for developing and implementing artificial intelligence (AI) and machine learning (ML) solutions. They deploy AI models in popular libraries and the tasks include optimizing algorithms to solve complex business problems and training and testing models to ensure accuracy and reliability. Teaming up with data engineers and data scientists they ensure the quality of data for AI models.
- language and libraries such as NumPy, Pandas, TensorFlow, Keras, and PyTorch.
- machine learning algorithms and deep learning frameworks and data preprocessing
- statistical analysis and techniques for data analysis, such as regression analysis, hypothesis testing
- Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), and their machine learning services.
- SQL and NoSQL databases, and data warehousing concepts.
Python Quality Assurance Engineer
Python Quality Assurance Engineers make sure that the quality and reliability of software applications developed is in the expected range. While they are supporting other Developers to identify and fix bugs and defects in the code, they as well design and execute test plans to validate the functionality and performance of the product shipped. Doing this they rely on various automation and testing tools and frameworks.
What to consider when you hire a Python Developer
Focus on Communication
Python Developers should have excellent communication skills, as they will need to collaborate with other Developers, Project Managers, and other stakeholders to ensure that the testing process is effective and efficient.
Academic Credentials over everything?
A degree in computer science can be a sign, but it is not always an accurate indicator of a developer’s skills or ability to work on a team and deliver. Some of our best developers are career changers with several years of experience on complex projects.
Soft Skills, anyone?
Next to the discussed communication skills we see a strong benefit in candidates that offer adaptability in an ever changing environment, good problem solving skills, creativity and a good amount of emotional intelligence, to make the most out of social interactions with the team.
