In today’s fast paced data-driven world, data engineering is the lifeblood for data science, machine learning, and business intelligence. The second is the heavy investments companies make in cloud infrastructure, big data, and real-time analytics labors that result in skyrocketing demand for certified data engineers through 2025. No matter if you recently graduated, you’re a self-taught coder or a professional seeking a new skill set, a data engineer certification in 2025 can speed up your career in this high-paid field.
In this guide, we will discuss everything from understanding the data engineering landscape to finishing the best course and earning the certification that gets you started on your career. Here’s what you’ll need to know if you’re looking to become a certified data engineer in the new year.
Why to Choose a Career in Data Engineering?
But before we dive into the termination process, our first question is, why data engineering in the first place? I know you may be thinking it anyway.
Data engineers build the back-end infrastructure that enables analytics to run. Their work includes:
- Building and designing data pipelines
- Managing ETL/ELT workflows
- Integrating structured and unstructured data
- Making the most of storage with data lakes and warehouses
- Enabling data scientists and analyst with clean and reliable data.
What with the amount of data every industry already generates, people who can get everything organized, transfer what must move and manage what’s already there have seen their desirability explode.
Job Growth: Data engineering jobs are expected to grow by 35% in 2028, industry reports say.
Salary Range (India): ₹10 LPA to ₹28 LPA (depending on experience and specialization).
Let’s set some context first before jumping into what makes a data engineer. Data engineers are not coders at all, but they are infrastructure architects.
Core Responsibilities:
- Building data pipelines using tools like Apache Airflow or AWS Glue.
- Developing SQL and NoSQL ETL queries
- Developing the new and existing ETL process flows by working with business/program analysts, technical architects and vendors
- Coordinating and performing extraction
- Experience working with Apache Kafka or Flink based, streaming/real-time systems.
- Utilizing the cloud (AWS, Azure, Google Cloud, etc.)
- Working with the data science team on putting production scalable ML pipelines into place
From a software or data science perspective: Transition should be pretty easy, especially if you’re mainly fluent in Python, SQL, and distributed systems.
CHOOSE WHICH DATA ENGINEERING CERTIFICATION TO PURSUE
Now that you have the data engineer’s role information, let’s explore what you need certification-wise? Looking for ideas for places to go for New Year’s?
Google Cloud Professional Data Engineer
Concentration: GCP for data, ML pipelines, security, and scalability
Best for: Cloud native data engineers and anybody working with BigQuery, Dataflow, etc.
Cost: $200 USD
Microsoft Azure Data Engineer Associate (DP-203)
Focus: Azure Data with Synapse Analytics, Data Factory etc.
Ideal for: Enterprise engineers, Azure focused folk.

Cost: $200–$300 USD
The best data engineer certifications compared to the top contenders for data engineer certifications are going to be influenced by the ecosystem in which you want to specialize (AWS, Azure, GCP), as well as what tools you expect to rely on in your work.
Build a Strong Base with the Right Courses
In order to pass these certifications and excel on the job, you’ve got to build a great base. If you’re fairly new to the field, start with beginning (to advanced beginner) data science courses that cover subjects such as:
- SQL and Python programming
- Data Modeling and Normalization
- Basics of cloud platforms
Structured Learning Paths
There are learning paths available on a number of popular platforms:
Coursera – Data Engineering with Google Cloud, Data Engineering on Google Cloud by Google Cloud/IBM/Coursera
edX – Microsoft and AWS courses paths
Udemy – Apache Spark with Scala – Learn Spark from a Big Data Guru
Simplilearn/UpGrad – Job-ready bootcamps in India with capstone projects Simplilearn and UpGrad, two Indian edtech providers, got on the capstone project bandwagon to deliver job-ready bootcamps designed for the future of work.
It “forces” you to actually learn some analytical thinking, which comes in handy as you’re building ETL logic and trying to understand data.
Know the important tools/procedures
Data engineering, and that’s not just theory. These tools are vital for applications in the real world and for certifying tests. Here’s what you need to know:
Programming Languages
Python – scripting, data wrangling, automation etc..
SQL – It’s the Bible for any data pipeline or transformation
Data Pipelines
Apache Airflow
Luigi
AWS Glue
Cloud Platforms
AWS (S3, Redshift, Glue)
Azure (Synapse, Data Factory)
GCP (BigQuery, Dataflow)
Data Storage
Data lakes (Amazon S3, Google Cloud Storage)
warehouses(Snowflake, Redshift, BigQuery)
Workflow Tools
Kafka for real-time data
Spark to crunch gargantuan amounts of data in shared mode.
If you want to automate your infrastructure use Terraform.
These tools can be a great addition to your portfolios, they can be useful while preparing for scenario based questions in certification exams too.
Choose a Learning Path with Projects
To Do episodes cover the essentials, but future spotlights will present curated content that’s organized around a learning path with hands-on projects.
While still important, real-world experience is often valued more highly than certifications by employers. Consider programs that offer:
- Business use cases (i.e., real-time dashboards, fraud detection pipelines)
- Cloud -based time projects on the cloud.
- GitHub portfolio integration
- Advice for Mentors + Mock Interviews
Here’s where blended data science classes can offer the complete learning ecosystem: theory + tool + project.
Look for:
- Placements in Bootcamps Data Engineering
- Blended classes with in-person class components and self-paced challenging portions
- Experience with Spark, Kafka or AWS/GCP
Prepare for Your Certification Exam
Then, once you’ve completed the course and the hands-on work, start getting serious about studying for the exam.
Study Resources:
AWS, Azure, or GCP re:Cloud official exam guides
Testing Source WhizLabs, TestPrep, Udemy You should follow the testing source as well, if there is any.
Whitepapers and Documentation (AWS particularly )
YouTube tutorial (for the last-minute crammer)
Study Tips:
Devote an hour to two each day for one month
So build a set of digital flashcards, (can store them with Anki or Notion) # 10.
Set up an example project, to be our “pipelining person in the wild”
Focus not only on theories, but also on case studies
Take the Exam; Become a Certified Masseuse
Book your exam using the certification provider’s website (Pearson VUE or PSI). The majority of the tests are proctored online, and you will need:
- A working webcam
- A clean room setup
- Valid government ID
You will earn a sharable digital badge upon passing the test. Add this to your:
- LinkedIn profile
- Resume
- GitHub repository
This is your gateway to the world of mid/senior data engineering positions.
