What Is a Knowledge Engineer? Wage, Duties, & Roadmap

Knowledge is the brand new oil. However who extracts and refines this oil? Knowledge engineers! Knowledge engineers design and develop techniques to transform uncooked knowledge to high-quality knowledge that can be utilized for evaluation and modeling.

Step one of any data-centric group is to collect knowledge from disparate sources. The information is then remodeled into the required format and loaded into the information infrastructure. Knowledge scientists and analysts can then entry the information to extract insights and clear up enterprise issues. The information engineer leads this entire course of. With out knowledge engineers, organizations shall be unable to make use of their knowledge successfully, which may result in a lack of enterprise alternatives.

Knowledge engineering is a high-paying profession as effectively. As per Glassdoor’s estimate, the median knowledge engineer wage is $113,784 per 12 months in the US.

On this weblog, we’ll focus on causes, obligations, and the roadmap to changing into a extremely expert knowledge engineer, and the way an information engineer differs from an information scientist.

Why Change into a Knowledge Engineer?

Knowledge engineers are the necessity of the hour. They’re an integral a part of an organization’s knowledge technique as a result of the rate, quantity, and selection with which we’re producing knowledge are growing quickly.

By the top of 2025, greater than 180 zettabytes of information shall be created, captured, and consumed. We want knowledge engineers to deal with such an enormous quantity of uncooked knowledge. With such excessive demand, it presents a promising profession within the knowledge ecosystem.

Duties of a Knowledge Engineer

An information engineer’s job is to know the group’s knowledge necessities and construct techniques to supply clear, accessible knowledge. On a day-to-day foundation, they carry out the next duties:

  • Designing, constructing, and sustaining the information pipelines
  • Working with knowledge analysts and scientists to raised perceive the information necessities
  • Validating knowledge sources and specializing in knowledge high quality
  • Making certain compliance with knowledge rules

How you can Change into a Knowledge Engineer?

The roadmap to changing into an information engineer is as follows:

1) Buying Related Knowledge Engineering Expertise

a) Coding

In accordance with an evaluation of 17,000 knowledge engineer job postings, greater than 70% of recruiters search candidates proficient in Python and SQL. Therefore, studying Python and SQL ought to be step one to changing into an information engineer. Furthermore, familiarity with different programming languages, reminiscent of Scala and Java, may give you a aggressive benefit.

b) ETL (Extract, Rework, Load)

ETL means extracting knowledge from varied sources to single storage, remodeling it right into a kind supposed for evaluation, and loading it into an information warehouse. Creating and sustaining ETL pipelines is an information engineer’s duty. Therefore, studying ETL instruments reminiscent of Combine and Talend is important for knowledge engineering.

c) Knowledge Storage Methods

Databases are used to retailer the gathered knowledge. Familiarity with relational, NoSQL, and knowledge lakes as totally different knowledge storage sorts is important.

d) Massive Knowledge Instruments

Understanding large knowledge instruments reminiscent of Apache Spark, Apache Hadoop, and Apache Hive is important for changing into an information engineer. These instruments are used for processing, storing, and querying giant volumes of information.

e) Cloud Computing

Cloud suppliers reminiscent of AWS (Amazon Net Companies) and Microsoft Azure present scalable computational assets for knowledge storage and processing. Cloud computing certifications can assist you study and apply the elemental and superior ideas of assorted cloud platforms.

f) Delicate Expertise

An information engineer ought to have good communication abilities to collaborate with different crew members, together with knowledge scientists and knowledge analysts. Creativity and problem-solving can assist clear up challenges within the knowledge engineering lifecycle.

2) Getting Certification

Certifications improve credibility and acquire your employer’s belief. Knowledge engineering certifications may be acquired from credible instructional platforms like Coursera and Udemy. They’ve a high-quality sensible curriculum taught by expert educators. However, learn course and teacher evaluations earlier than registering your self. You may also go to the LinkedIn profiles {of professional} knowledge engineers to seek out out which certifications they’ve acquired. It will provide you with a greater understanding of which instruments or platforms are presently trending within the business.

3) Constructing Your Knowledge Engineering Portfolio

A portfolio is among the finest metrics to evaluate a candidate’s understanding of the topic. Creating a number of initiatives associated to database design and improvement can distinguish you from different candidates. Importing your knowledge engineering challenge on GitHub and sharing a walkthrough weblog publish on platforms reminiscent of LinkedIn or Medium is a vital step to showcasing your knowledge abilities.

4) Securing an Entry-Stage Knowledge Engineering Job

Usually, knowledge engineering is just not an entry-level place. Getting an entry-level job as an information analyst is usually a good begin. As you acquire extra expertise and abilities, you possibly can work up to an information engineer place.

Main Variations Between a Knowledge Engineer & a Knowledge Scientist

Though there are some similarities between the abilities and instruments utilized by knowledge scientists and knowledge engineers, there are some distinct variations between them that are as follows:

Parameter Knowledge Engineer Knowledge Scientist
Duties Making knowledge infrastructures (knowledge warehouses, knowledge lakes, and many others.) for knowledge evaluation is the important thing duty of an information engineer An information scientist is chargeable for discovering hidden patterns, constructing fashions, and making predictions on unseen knowledge
Experience Experience in database design and ETL processes utilizing Python, SQL, and Java Proficient in knowledge visualization, statistical evaluation, and machine studying utilizing Python or R
Instruments SQL Databases, MongoDB, Apache Spark, Apache Hadoop, and Cloud Platforms (AWS, GCP, and many others.) Pandas, Scikit-Study, Tableau, PyTorch/TensorFlow, and Cloud Platforms
Finish Aim To supply high-quality, accessible knowledge Resolve complicated enterprise issues and assist corporations make data-driven selections


Knowledge engineer comes seventh in Glassdoor’s 50 Finest Jobs in America for 2022. As large knowledge roles within the data-centric group get clearer, the demand for knowledge engineers will proceed to extend.
