According to LinkedIn, data engineering jobs are on the rise at around 50% YoY and for good reason. As companies rely on data more than ever before, they need data engineers to manage and process it effectively. This trend is expected to continue as more devices and applications become connected and generate more data.
Despite the growth of the field, businesses face significant challenges when it comes to recruiting top-notch data engineers. There is a shortage of data engineers with the right combination of technical and soft skills. With the role in high demand, businesses often compete with other companies to hire the best candidates.
Using some of the top sites to hire can eliminate these problems for you. For instance, when you work with Toptal, everyone has been vetted before you ever log on. There is no work for you to do to find the next member of your team.
Working with freelancers and remote workers offers a lot of perks. A freelance data engineer can be more cost-effective than hiring a full-time employee, especially for short-term projects. It's also easy to find and hire a data engineer who has a very special skill set.
What Does a Data Engineer Do?
What does a data engineer do, and why is it even necessary to hire data engineers? It really depends on where your business is when it comes to growth. Once you have several data scientists and analysts generating information, it's time to bring in a data engineer to support them. Data engineers can take care of many things, including:
- Designing and implementing a robust data architecture that can support your business's data needs, including building data pipelines, data warehouses, and data lakes that can store and process data effectively
- Integrating data from various sources, including databases, APIs and third-party services, into a single system
- Building efficient ETL (extract, transform, and load) processes that can transform data from raw format to a format that is easy to work with
- Ensuring that the data your business works with is of high quality by implementing data validation and cleansing processes
- Designing a scalable data infrastructure that can grow with your business's needs
- Implementing analytics and reporting tools that allow businesses to make data-driven decisions
Each of these processes will enable your business to operate more efficiently and put you in a better position for growth in the future.

Hiring a Freelance Data Engineer
If you need to add one or more data engineers to your team, you must decide if you’ll use part-time, full-time, or freelance engineers. Each has advantages, but freelancers are often your best bet. Why?
- You won’t have additional expenses such as overhead costs, payroll taxes, and benefits.
- Some skill sets are rare and difficult to source from local talent pools. With a broader search area, such as Toptal’s global platform, there’s a much greater chance of finding engineers with those skills quickly.
- When you utilize freelancers, you agree to by-the-hour or other project-based pricing and hiring structures. When the project is finished, so is your contract with the freelancer. Hiring employees is a more permanent, committed step; if you terminate them when your project is completed, you’ll likely pay unemployment and a severance package.
- Many freelance sites offer risk-free trial periods that allow you to assess an engineer’s performance and fit.
- You can often hire qualified freelancers in days, as opposed to weeks or months with employees.
Hiring freelancers provides cost savings and invaluable flexibility.

Tips for Writing a Data Engineer Job Description
Your first step in the hiring process is to define your project parameters:
- Budget
- Desired start time and project duration
- Detailed project description, specifying its nature and scope
- The number and types of hires you’ll make
You need to describe your position in an appealing way. Highlight your company’s successes and culture, along with how you envision the data project helping your company. Include role-specific details such as duties, qualifications, and requirements.
Before you begin interviewing applicants, compose a standard set of questions and create a consistent scoring model. That way, your results are inclusive and unbiased.
Common Interview Questions To Ask When You Are Looking To Hire a Data Engineer
Applicants who make it to your interviewing step have technical skills that qualify them as top candidates. Data engineers have more responsibilities than most, so you should require each one to complete identical technical projects to:
- Learn how they approach and resolve problems
- Gauge how well they work under pressure
- See how quickly they complete the project
- Identify the steps they take to ensure accuracy
Having impressive qualifications got them to the interview, but seeing each candidate in action and comparing your observations is priceless.
Interviews are your chance to gauge soft skills. Develop a situational scenario, but omit some pertinent details. A good engineer will ask for additional information before answering the question. You’ll gain invaluable insights into the candidate’s thought processes and communication skills.
Other interview questions should include:
- How did you contribute to past projects and what did it achieve? You’ll obtain data about problem solving, competence, quantifiable results, and the engineer’s level of confidence.
- Do you work well with teams? or How would you manage a team? Depending on the role, you’ll learn about work habits, collaboration abilities, and leadership skills.
It’s often difficult to decide between top candidates. When you hire a freelance data engineer through sites like Toptal, you have the opportunity to see if you made the right choice during a risk-free trial period.
