Here are the top skills for data engineers to build in 2025:
1. Master the Fundamentals of Programming and Data
A strong foundation in programming and databases is crucial. Data engineers primarily use languages like Python (for its rich ecosystem of data libraries) and SQL (for querying and manipulating data).
Make sure you’re comfortable writing scripts to process data, as well as writing efficient SQL queries for relational databases. It’s also helpful to understand fundamentals of computer science (data structures, algorithms) because efficiency matters when dealing with large data volumes.
If you’re just starting out, begin with courses that cover Python, SQL, and database design. For instance, our Data Analytics Program is a great entry point that covers these basics and gives you hands-on practice with data analysis and databases.
This can build a base from which you can advance into more specialized data engineering topics. Some data engineers start their careers as data analysts or software developers, where they cultivate a solid foundation before moving into pipeline development.
2. Learn Big Data Platforms and Cloud Services
Next, focus on the core tools of the data engineering trade. This means becoming familiar with big data frameworks like Apache Hadoop and Apache Spark for processing large datasets, and understanding distributed storage systems (e.g., HDFS or cloud-based storage like S3).
Since most data engineering is now cloud-based, learn the data services of at least one major cloud platform. AWS has services like S3, Redshift, Kinesis, EMR; Azure offers Azure Data Lake, Synapse Analytics; GCP has BigQuery, Dataflow, etc.
Learn how to load data into data lakes/warehouses, how to transform data at scale, and how to optimize cloud resources (for cost and speed). The Data Engineering Program we offer introduces learners to these big data and cloud technologies step by step.
You might work on projects using Spark to crunch data or design a pipeline that takes data from a source like Kafka into a cloud warehouse. Gaining certifications in cloud (like AWS Certified Data Analytics or Azure Data Engineer Associate) can also boost your resume at this stage.
3. Develop Pipeline Design and Data Architecture Skills
Data engineering is about building systems, so you need to think like an architect. Learn how to design ETL/ELT pipelines that reliably move data from sources (APIs, databases, logs) to destinations (data lakes, warehouses, analytical tools).
Key concepts include understanding different data storage formats (CSV, JSON, Parquet), data modeling for warehouses (star schema, snowflake schema), and tools for workflow orchestration (Apache Airflow, Luigi).
Practice by designing a simple data pipeline end-to-end: for example, ingest public data, clean and transform it, load it into a database, and schedule that pipeline to run automatically.
Also, familiarize yourself with concepts of data modeling and database design – a data engineer often decides how to structure tables or partitions for optimal use by others. Think about things like schema design, indexing, and query optimization.
In our program, you get to build mini-projects that simulate real business data scenarios (like constructing a data warehouse for sales data or setting up a streaming pipeline for clickstream data). This project-based learning cements your ability to design and implement pipelines, not just use tools in isolation.
4. Embrace Software Engineering and DataOps Practices
Modern data engineering teams expect you to apply good software engineering practices to data projects. This means using version control (Git) for your code, writing modular and reusable code (possibly turning repeated logic into functions or libraries), and documenting your work.
Learn the basics of DataOps and automation. For instance, how to containerize applications using Docker, and how to deploy them on platforms like Kubernetes for scalability. Infrastructure-as-code tools (Terraform or CloudFormation) can be used to script the setup of data environments.
Automated testing is another aspect: you might write tests to validate that your pipeline outputs correct data. CI/CD pipelines can automate the deployment of your data workflows.
While this might sound advanced, even a basic understanding of these principles will set you apart as a candidate. Many training programs now incorporate this practical know-how.
You'll be using Git and CI pipelines in your Refonte Learning’s projects, so that you get a feel for collaborative, production-like development. Essentially, treat data pipelines as production software: robust, tested, and maintainable.
5. Get Hands-On Experience through Projects or Internships
Experience is critical. Build a portfolio that showcases your data engineering capabilities. This could include personal projects.
For example, constructing a data pipeline that pulls data from a public API (like weather or stock data), stores it, and provides some analysis or visualization on top. Document these projects on GitHub.
Additionally, internships (even virtual ones) are invaluable because they expose you to real-world datasets, team workflows, and the end-to-end lifecycle of data in a company.
An internship might have you do things like optimize a slow SQL query, migrate a pipeline to the cloud, or set up dashboards for monitoring pipeline health. If you can’t find a formal internship, consider contributing to open-source projects or data engineering communities (some open source projects need help managing data or writing connectors).
Refonte Learning Data Engineering Program includes a virtual internship component where you work on live projects under mentorship. This means by the time you finish, you have tangible projects to discuss in interviews.
Aim to have a few solid examples you can talk about: times when you had to troubleshoot a broken pipeline, improve performance, or ensure data correctness.
6. Continue Learning and Networking
Data engineering is a fast-evolving field. New tools (like emerging data orchestration platforms or novel database technologies) continue to appear. Adopt a mindset of continuous learning.
Follow blogs, YouTube channels, or podcasts on data engineering to keep up with trends like data mesh, new open-source tools, and best practices.

Knowledge of DevOps/DataOps practices (Docker, Kubernetes, CI/CD) is increasingly valued to deploy and manage data infrastructure.
Problem-solving and communication: Beyond technical skills, a good data engineer needs strong problem-solving abilities (to troubleshoot pipeline issues, optimize performance) and communication skills. You’ll often work with data scientists, analysts, or other stakeholders, so being able to understand requirements and explain data pipeline designs is important.
The good news is that you can learn these skills through structured programs. Refonte Learning’s Data Engineering course, for example, covers many of these areas with hands-on projects – from Python/SQL basics to building cloud-based pipelines – so that you graduate with the practical abilities needed for entry-level roles.
Q: How is a data engineer different from a data scientist or data analyst?
A: While these roles all work with data, they focus on different parts of the data value chain:
Data Engineer: A data engineer’s primary focus is on building and maintaining the data infrastructure. They design pipelines, integrate data from various sources, ensure databases and data lakes are running smoothly, and optimize data storage for performance. In essence, data engineers make sure that clean, reliable data is available to others (like analysts and scientists). It’s a role that requires strong software engineering skills and knowledge of systems.
Data Scientist: A data scientist focuses on analyzing data and building models to derive insights or make predictions. They use statistical methods and machine learning algorithms on the data (often data that’s been prepared by data engineers). Data scientists are the ones who might build a predictive model to forecast sales or an AI algorithm to detect fraud. Their work is more exploratory and model-centric, and they typically use languages like Python or R with libraries for analysis. While a data scientist relies on having data, they typically are not the ones structuring the pipelines in production (though in smaller teams, the lines can blur).
Data Analyst: A data analyst is often concerned with interpreting data and producing reports. They use tools like SQL, Excel, or BI software (Tableau, Power BI) to answer business questions and generate dashboards or reports. Analysts might not build complex models like a data scientist, but they have deep knowledge of the business domain and provide insights into trends, summaries, and visualizations. They often work with the data that exists in data warehouses (which data engineers populate) to create weekly reports, KPIs, etc.
In summary, data engineers build the highways and pipelines for data, data scientists create the advanced algorithms and models that run on that data, and data analysts derive and communicate insights to inform business decisions. All three roles are complementary.
In many modern teams, there’s also an analytics engineer role emerging that sits between data engineering and analysis, focusing on transforming data in the warehouse for easier analysis (often using SQL and analytics tools).
If you’re unsure which path to choose, consider your interests: if you enjoy coding and building systems, data engineering is great. If you love statistics and machine learning, data science might suit you more.
And if you excel at interpreting data and supporting business decisions, data analysis could be the path. There are also opportunities to move between these roles as you gain experience, since they share overlapping skills.
Q: Will automation or AI replace data engineers in the future?
A: It’s unlikely that automation or AI will replace data engineers; instead, these advancements will augment the role.
We are seeing more automation in data engineering – for example, tools that can automatically adjust or generate pipeline code, manage schema changes, or even “auto-tune” databases. AI is being used to simplify some tasks, like identifying data anomalies or suggesting pipeline optimizations.
However, the expertise of a human data engineer is still crucial. Each organization’s data landscape is unique, with different sources, business rules, and constraints. Data engineers provide the critical thinking and contextual understanding to design the right architecture and fix issues when things break unexpectedly.
Automation can handle repetitive tasks (such as scheduled jobs, basic transformations, or monitoring), which actually frees up data engineers to focus on more complex aspects of the job.
Rather than writing boilerplate code, engineers can spend more time on high-level design, optimization, and new data initiatives. In 2025, what we anticipate is not the removal of data engineers, but a shift in their work: leveraging smarter tools to be more productive.
For example, a data engineer might use an AI-assisted mapping tool to quickly integrate a new data source, but they still need to validate that data and incorporate it correctly into the data model.
They might rely on automated alerts for pipeline failures, but when an alert triggers, it’s the engineer who must diagnose and resolve the root cause. So, much like how DevOps engineers still have jobs despite infrastructure automation, data engineers will continue to be in demand.
In fact, those who learn to use automation and AI tools effectively will be even more valuable, as they can accomplish more with the same time.
Refonte Learning’s curriculum touches on this by introducing students to modern data engineering platforms and showing how to work alongside automation tools. Embracing these technologies is part of the evolution of the role, but the need for creative, knowledgeable data engineers isn’t going away.
Q: How can I land my first job as a data engineer?
A: Breaking into your first data engineering role can be challenging, but here are some strategies to help you succeed:
Build a Portfolio of Projects: Since many entry-level candidates lack job experience, a project portfolio can set you apart. Create a few portfolio projects that demonstrate core data engineering skills. For example, build a data pipeline that gathers data from an API or public dataset, transforms it, and loads it into a database or data warehouse, then perhaps run a simple analysis or visualization on it. Document your project: use a GitHub repository to show your code, include a README that explains your design and results. A good project might involve technologies like Python, SQL, maybe a bit of Spark or Kafka if you’re comfortable, and a cloud service or two. Quality matters more than quantity – even 2-3 well-done projects can impress hiring managers.
Leverage Internships and Virtual Experience: If possible, get an internship in a data or engineering team. Even if the title isn’t “data engineer”, anything that lets you work with data pipelines or databases is valuable. Real-world experience teaches practical skills (like debugging pipelines, data documentation, teamwork on data issues) that you can discuss in interviews. If in-person internships are scarce, consider virtual internships or apprenticeship programs. As mentioned, Refonte Learning’s Data Engineering Program offers a virtual internship, which you can highlight as work experience since you collaborated on real projects. When applying to jobs, experience from these programs can often be presented just like a job, especially if you delivered concrete outcomes.
Target Entry Points: Sometimes, the first job might not be a pure “Data Engineer” title. Many people start as data analysts, business intelligence developers, or junior ETL developers and transition to data engineering. These roles still involve a lot of data work and can help you get into the company. Once you’re in, you can pivot internally or gain the experience to apply for a true data engineer position elsewhere. Another entry point is consulting firms or managed service providers – they often hire juniors to train on their data platforms, which gives broad exposure.
Prepare for Interviews: Data engineering interviews often cover SQL and programming questions, and sometimes design scenarios. Practice writing SQL queries (including complex joins and aggregations) and some basic Python scripts for data manipulation. You may be asked conceptual questions like how to design a pipeline for a given problem or how to model a database for a scenario. Be ready to explain your portfolio projects in detail – what challenges you faced, how you chose tools, what you’d improve. Also, review fundamentals like normalization, differences between batch vs streaming, and maybe basics of distributed systems (e.g., why Hadoop uses MapReduce, or how Spark improves on it) for technical conversations.
Network and Use Referrals: Networking can greatly increase your chances. Connect with data engineers or hiring managers on LinkedIn – sometimes politely asking for a informational interview or advice can lead to referrals if a position opens. Attend virtual meetups; even asking questions there can get you noticed. If you went through a program like Refonte Learning, use their career services and mentor connections – they might refer you to partner companies or guide you to job openings. Many jobs aren’t advertised widely, so having someone in the industry vouch for you can get your foot in the door.
Highlight Relevant Skills: Tailor your resume for each application. Emphasize projects and coursework that match the job’s requirements. If a job mentions Kafka or AWS and you’ve used them in a project, make sure that’s front and center. Even soft skills like “problem-solving” or “fast learner with strong analytical skills” are good to mention, as data engineering often requires troubleshooting abilities.
Landing the first job might take time – it’s not uncommon to apply to dozens of positions. Keep learning during the process (you can discuss in interviews how you’re currently learning X technology), and consider getting certified in a technology if you have downtime (for example, AWS or Azure data engineer certifications).
Each step you take improves your profile. With persistence and the right preparation, you will break into your first data engineering role. And once you have that first experience, subsequent opportunities will come more easily.
