Who is a Data Engineer?
Data engineers oversee the design, development, and management of database architecture and data processing systems. The most technical job descriptions in data science are data engineers, who play a vital role in bridging the gap between traditional data science professions and software and application developers.
Responsibilities
Data engineers are responsible for the following:
✔️The process of data collection, analysis, storage, and movement of data, which is the initial step in the conventional data science workflow, is handled by data engineers.
✔️Monitoring the flow and status of data within the systems.
✔️Data engineers must have advanced knowledge of both SQL and data modeling.
✔️The daily activities of a data engineer mostly revolve around two processes:
ETL (Extract, Transform, Load) procedures, which involve creating tasks for data extraction, transformation, and loading, as well as transporting data between various environments.
Data cleaning procedures ensure that information reaches analysts and data scientists in a standardized and structured state.
✔️They are responsible for creating and controlling the data pipelines and programs that move data.
✔️They collaborate closely with the organization's data scientists and other analytics experts.

Skills Required
The following section describes the skills and experience needed to be a data engineer.
✅Database management: Data engineers spend a significant portion of their day working with databases, whether to gather, store, transfer, clean, or consult data. Consequently, data engineers need to be knowledgeable about database management.
✅Programming languages: Coding is necessary for data engineers, just like other data science positions. Data engineers use different programming languages in addition to SQL for various jobs. They should be well-versed in programming languages like Python, Java, and C++. Python works well with essential data engineering tools and frameworks like Apache Airflow and Apache Spark.
✅Communication skills: Data engineers require strong communication abilities to collaborate with people from other departments and comprehend the demands of business executives, data scientists, and analysts. Data engineers may also need to know how to create dashboards, reports, and other visualizations to communicate with stakeholders, depending on the organization.
✅Distributed computing frameworks: A distributed system is a computing environment where different components are dispersed over several computers (sometimes referred to as a cluster) connected to a network. Massive volumes of data processing are the main focus of distributed computing frameworks like Apache Hadoop and Apache Spark, which serve as the building blocks for some of the most amazing big data applications. Any aspiring data engineer must possess some knowledge of one of these frameworks.
✅Tools and libraries: They should be knowledgeable in analytical tools (such as Power BI and Tableau), machine learning libraries (such as Tensorflow and PyTorch), and other technologies that assist with analytical projects (like ETL tools and big data systems)
✅Stream processing frameworks: Some of the most advanced applications in data science involve real-time data. For data engineers looking to advance their careers, one must understand how to use streaming processing tools like Flink, Kafka Streams, or Spark Streaming.
✅Cloud technology: The market is quickly evolving due to the desire for cloud-based solutions. As a result, a skilled data engineer needs to be knowledgeable about using cloud services and their integration with Big Data initiatives. One should at least be familiar with AWS or Azure.
Preparation Strategy
To start preparing to become a data engineer, first, you must fulfill the skills and experience required in the previous section. After acquiring the required skills, knowledge and experience, you should start building projects showcasing your data engineering skills. Once you have built a few projects, share your projects with others on GitHub.
Now comes the next phase, the selection process.
An interview for data engineering is typically divided into technical and non-technical parts. During the technical part, hiring managers will evaluate your technical skills for the position as well as your data engineering skills. Expect questions regarding:
▶️Your resume: Employers are interested in learning about your data engineering-related experiences. For recruiters to evaluate your technical, problem-solving, communication, and project management skills, make sure to highlight in your resume any previous data science positions and projects you have worked on. Additionally, be prepared to provide full details about these projects.
▶️Programming skills: Using Python or a data framework like Spark, you will be required to solve an issue in a short amount of time and with a few lines of code.
▶️SQL: In addition to the programming test, you can also be required to use SQL to solve a problem. Writing effective queries to perform data processing in databases is typically the exercise.
▶️System Design:System design is the technical interview's most complex and likely most challenging section. Data engineers' most important jobs include designing data architectures. You will be required to build a complete data solution in this section, which typically consists of three components: data storage, data processing, and data modelling.
Your potential team members will conduct a personal interview with you after you have finished the technical part of the data engineering interview.
Career Path of a Data Engineer
Junior Data Engineer
Junior data engineers generally take on little jobs supporting and maintaining existing systems when they begin their careers. This could involve anything from testing systems to finding and correcting flaws to enhancing an existing system with new features. The most crucial aspect of a junior data engineer's early years is learning and acquiring practical experience with the technologies they will use in the future of their careers. Additionally, they are learning how the many teams and departments collaborate to discover answers to problems and inquiries that arise.
Mid-Level Data Engineer
After one to three years, a data engineer can be promoted to the mid-level.
They are typically responsible for developing and designing the systems that support data scientists and other analytical team members. At this point, they might still be under the direction of a senior data engineer.
Senior Data Engineer
When data engineers advance to a senior position, they handle more managerial duties. They mentor and assign work to one or more data engineers who work under them. At this point, the data engineer has mastered the technical facets of their job and can create systems and find solutions with reasonable ease.
Senior Managerial Roles
Data engineers can opt to go into more managerial roles once they have at least six years of experience, such as:
Director of data engineering
Chief data officer
Data engineering manager
These roles require the data engineer to have robust data infrastructure and architecture skills and be highly proficient in the technical skills acquired during lower levels. They also demand the data engineer be able to lead and scale analytical teams. Additionally, they must be able to scope out new projects and specify the procedures for creating high-performance systems.
