4 Steps to Creating a Big Data Engineer Job Description That Fits Your Needs

With a big data engineer job description template in hand, it’s time to write that job post. Although you don’t need a complete job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project. Below are some factors to consider when writing your job description:

1. Determine What Type of Big Data Engineer You Need

The type of big data engineer you need will be determined by how you will use the data output. Some big data engineers work with business intelligence and machine learning platforms to create dashboards and reports for internal use.

Other big data engineers work in environments with data pipelines in order to develop and analyze data to create tools for external clients. Determining your need first will help in understanding the correct type of big data engineer you need.

2. Employee vs. Independent Contractor vs. Agency

A big data engineer can be hired in-house, contracted through an agency, or hired independently as a freelancer. A big data engineer might specialize in certain technologies, such as Hadoop, using programming languages like Java, NoSQL, Python, Hive, Spark, Apache, and Sqoop. In addition, a big data engineer might be well versed in SQL and shell scripting and have experience working in a cloud environment.

No matter which direction you go to fill your needs, an independent contractor might provide the most flexibility, as they can be deployed to any number of projects when needed at a competitive rate. Worker classification can be tricky, so check out our compliance services resources page for more information.

3. Experience

The more experienced a big data engineer is, the more complex tasks they’ll be able to perform for your business. An entry-level big data engineer might help your business with very straightforward projects such as sourcing and compiling data with easy-to-use tools. Alternatively, you might consult with a senior big data engineer to help with advanced projects that feature various platforms, multiple development languages, and a variety of reporting capabilities. Your project scope will determine the type of experience required for the job.

4. Industry

It’s possible a big data engineer can work in any industry. The nature of the work being done can be similar across multiple industries, therefore allowing engineers to have experience in more than one area. There are, however, some big data engineers who specialize in certain industries where analyzing a great deal of data is necessary. Such industries include insurance, banking, consumer goods, auto manufacturing, virtual reality development, and software development.

While you can hire a big data engineer with experience across multiple industries, identifying the right fit might mean finding one who has experience in your industry.

Next Steps

Now that you know how to write an effective big data engineer job description, you’re ready to check out our list of top big data engineers on Upwork. Their qualifications are listed along with their experience, giving you all the information you need to find the right fit for you.

Hi, I’m Anthony — a battle-tested AWS Certified Solutions Architect (Professional) with 23+ years of IT experience and a strong record of designing, building, and securing enterprise-grade cloud systems across industries. Think of me as your Swiss Army knife for all things cloud, with a specialty in AWS, security architecture, DevSecOps, and scaling operations without breaking the bank (or your infrastructure). I’ve been everything from a Principal Cloud Architect for Fortune 500s to the founding CTO of a tech startup — which means I don't just get the tech, I understand the business behind it. Whether you're launching a greenfield cloud environment, migrating legacy workloads, or building out secure, multi-account AWS orgs with Terraform and Control Tower, I can help you go from zero to scalable. Deep hands-on skills in AWS (Control Tower, IAM, Lambda, S3, RDS, etc.) Serious chops in cloud networking (Transit Gateway, Cloud WAN, BGP… you name it) Full-stack DevSecOps automation using Terraform, CI/CD pipelines, and GitHub Actions GenAI experience with SageMaker, Bedrock, and LLMs (yes, I play nice with robots) Also, I’ve been known to mentor teams, lead cloud centers of excellence, and — rumor has it — bring good vibes to meetings. Let’s simplify your cloud complexity and get stuff done. Efficiently. Securely. Elegantly.
