Data Engineer Skills: 10+ Most Essential

What Is Data Engineering?

Your business most likely creates data from internal systems or services, interfaces with third-party apps and providers, and must offer data in a certain format for various users and use cases.

Data generated and gathered by your company is likely subject to compliance standards, which you must preserve under the law. When this is the situation, your data’s security becomes a primary responsibility, posing new technical hurdles for data in transit or at rest.

Not only should your data be safe, but it must also be accessible to your end-users, function well enough to meet your business needs, and be accurate. Your data cannot bring value to your firm if it is secure but unused. Many parts of a data governance approach necessitate specialist knowledge. Data engineering is used in such situations.

What Is a Data Engineer?

Data engineers design systems that gather, handle, and transform raw data into useful information for data analysts and industry experts to comprehend in a range of scenarios. Their main goal is to make the data more available so that businesses may assess and improve their performance.

Performing in a generalist capacity in a smaller company frequently entails taking on a broader variety of data-related activities. Data engineers are dedicated to developing data pipelines at larger companies, while others are focused on maintaining database systems.

Top 10 Skills for Data Engineer

If you are keen to make a career as a data engineer, below are a few of the key skills that you must master.

Top Courses To Become A Data Engineer In 2022

1. Understanding of Database Management Systems

The SQL programming language is the industry standard for organizing and maintaining relational database applications. NoSQL databases come in a number of shapes and sizes, based on their data model, including a graph or text. It is a required knowledge for data engineers.

2. Python

Python is a popular programming language that continues to grow in popularity. To be able to develop manageable, reusable, and complicated functions, data engineers must be proficient in Python. This language is fast, flexible, and ideal for text analytics. It also provides a solid basis for big data support.

3. Data Warehouse Solutions

For inquiry and research, data warehouses hold massive amounts of new and historical data. This information comes from a variety of places, including CRM systems, accounting systems, and ERP software.

The data is then used for monitoring, analysis, and data mining by the organization. Most employers require entry-level engineers to be conversant with Amazon Web Services (AWS), a cloud computing platform that includes a diverse set of data storage technologies.

4. Writing That Is Clear and Concise

Many ambitious data engineers overlook soft skills, putting themselves at a disadvantage in terms of job chances. The following are the most significant advantages of writing for data engineers:

  • Consolidate your understanding: Writing blogs helps to process and strengthen your understanding of complicated professional concepts.
  • Others will be able to understand complex facts: You may be responsible for communicating data and results to supervisors, team members, and third parties, which necessitates the ability to write effectively and concisely.

5. Communication With People

Sorry, but it’s necessary 🙂

A data engineer works with a variety of stakeholders, including data scientists, chief technology officers, programmers, designers, customers, machine learning engineers, and many others. 

According to LinkedIn research, communication – especially interpersonal communication – is the most desired soft skill by employers. You must improve your interpersonal communication abilities.

6. ETL (Extract, Transfer, and Load) Tools

ETL is the process of extracting data from a source, converting it into a structure that can be analyzed and storing it in a data warehouse. This procedure uses batch processing to assist users in analyzing data that is relevant to a particular business challenge. 

The ETL collects data from a variety of sources and implements business rules to the data, which is why knowing ETL tools will help you in getting a good job. You can use data monitoring tools to collect data from several sources. Some of the top data monitoring tools include:

  • DataDog: You can use Datadog’s maturity model to assess your DevSecOps skills and automate data.
  • Moogsoft: Moogsoft’s sophisticated correlation finds anomalies and links the tissue between all warnings, allowing you to find the root cause more quickly.
  • Splunk: Splunk creates web-based applications for finding, monitoring, and analyzing machine-generated data.
  • Resolve.io: Using SaaS, you may rapidly automate your common IT activities with unique accelerator packs in a no-code experience.
  • Acure: This AIOps platform helps you collect logs and monitor data by using a low-code automation engine.
  • PageDuty: PagerDuty can easily be integrated into and added to the arsenal of any team for AIOps.
  • ScienceLogic: Customers can manage IT environments with ScienceLogic and AIOps at speed, scalability, and in real-time.

7. Time Management

Every part of a data engineer’s job can be improved if they have strong time management abilities. In our line of business, there are a lot of things that might keep you up at night, so being able to organize your day and stick to it is a huge plus.

Time management improvements that contribute to happy data engineers include:

  • Less worry and stress;
  • A more favorable work-life balance;
  • On-time project completion;
  • More time to devote to own pursuits or leisure activities;
  • There will be less procrastinating.

8. API Data

An API is a data access interface for software applications. It enables two apps or devices to communicate with one another for the purpose of completing a certain job. Web apps, for example, employ API to interact between the user-facing front end and the back-end functions and data. In order for data analysts and business analysts to explore the data, data engineers create APIs in databases.

9. Learning the Fundamentals of Distributed Systems

One of the most valuable data engineer skills is to learn Hadoop fluency. The Apache Hadoop software is a system that utilizes basic programming principles to provide for the distributed processing of massive data volumes across clusters of machines. It’s built to expand from a single server to hundreds of devices, each with its own computation and storage capabilities.

10. Algorithm and Data Structure Knowledge

Although data engineers primarily focus on data filtering and refining, comprehending the large picture of the company’s overall data function, as well as defining milestones and ultimate goals for the business issue at hand, requires a fundamental understanding of algorithms.
