When people say “big data,” they aren’t kidding.
Every day, the human race creates 2.5 quintillion bytes of data. More data has been generated in the last 10 years alone than in the entirety of human history.
From world-changing arenas like healthcare and human rights to more day-to-day functions like sales and marketing, that data can inform our decisions and guide our actions, but only if we’re able to effectively manage it.
That’s where Data Scientists come in.
Companies around the world are hiring Data Scientists in droves, but there aren’t many candidates to go around so competition is fierce. The first step to hiring a great Data Scientist is writing a great Data Scientist job description, which brings us here today. We’ll walk you through what it is a Data Scientist does, provide some sample job descriptions and a template and even cover some salary information.

What Does A Data Scientist Do?
You can’t write a Data Scientist job description if you don’t know what they do, so let’s cover the basics before we go any further.
At the highest level, Data Scientists employ a mix of statistical and technical methodologies to extract meaning from the unbelievable volume of data we create every day. These insights are typically used to inform models and algorithms that power everything from sales pipelines to new product development.
Imagine you have a database that contains the purchasing behavior of every customer that’s done business with your company over the past 10 years. This information is a potential goldmine of insight. It can tell you what products to advertise to specific customers. It can tell you how to manage your inventory. It can even identify products you need to add to or drop from your shelves. The thing is, this database contains millions of individual data points, and gleaning meaningful insights from this information is impossible without a highly structured and automated process. This is why Data Scientists make the big bucks.
Data Scientists blend a mastery of statistics and mathematics with a host of highly technical skills. While requirements vary, most companies expect Data Scientists to bring experience in several key areas to the table:
- Machine Learning - “A field of artificial intelligence that uses statistical techniques to give computer systems the ability to ‘learn’ from data, without being explicitly programmed.”
- Natural Language Processing - “A subfield of computer science, information engineering, and artificial intelligence concerned with the interactions between computers and human (natural) languages; in particular how to program computers to process and analyze large amounts of natural language data.”
- Data Mining - “The process of discovering patterns in large data sets involving methods at the intersection of machine learning, statistics, and database systems.”
- Data Visualization - “To communicate information clearly and efficiently, data visualization uses statistical graphics, plots, information graphics and other tools.”
Data Scientists utilize many different programming languages, but some are more prevalent than others. You should be at least somewhat familiar with the following languages before attempting to write a job description.
- R - R is an open source language for statistical computing and data visualization. Its roots go back to 1976, and it remains one of the most utilized languages in data science.
- Python - Python is a general-purpose programming language popular with Data Scientists thanks to its simplicity and efficiency.
- SQL - SQL, short for Structured Query Language, allows programmers to access and manipulate databases.
While the work of a Data Scientist is highly technical, there are also a host of softer skills that are important for success.
Data Scientists are often handed messy, unstructured data sets and asked to derive insights, so look for candidates with a tenacious attitude and plenty of patience. Data Scientists are also tasked with presenting highly technical information to a non-technical audience (often at the senior level), so the ability to communicate clearly and speak with confidence is paramount.
Five Data Scientist Job Description Examples
Let’s take a look at a few real examples of Data Scientist job descriptions that we sourced from our seven online communities. Though these are real job descriptions, we have redacted some information to protect the privacy of the companies that originally posted them.

Data Scientist Job Description: Example 4
Data science is the core around which [Redacted] is built. The central value proposition of our product is that we provide e-commerce businesses the ability to:
- organize the overwhelming amount of data they deal with
- analyze it for patterns and predictions
- deliver these insights in a readily accessible, freely explorable way
- and do it again, repeatedly and reliably, as more data comes in the door
The data science team at [Redacted] can be found hard at work at each step above. Our projects range from the development and refinement of statistical models, to the design and implementation of scalable back-end infrastructure that powers our analyses, to collaboration with other teams at [Redacted] to make sure customers get the most out of our analyses.
We place particular emphasis on providing a robust system of statistical insights. Our goal is not to deliver a single paper or presentation’s worth of material, but to give our customers a powerful analytical toolbox. We can help them use it, but we also want them to be able to take it and run with it, exploring their data on their own and finding uses for our models that we hadn’t even thought of.
On top of that, we have an expanding customer base and a growing interest in developing analyses and statistical modeling pipelines that extend beyond e-commerce. With more customers, richer data sets, and new domains of exploration, we’ll face bigger and bigger challenges, but we think we’re up for it, and we are looking for people who want to join us for the ride.
Specifically, we are looking for:
- A solid foundation in statistics, either demonstrated through academic study or work experience.
- Experience with at least two programming languages and one general-purpose statistical package or programming library. The data science team mainly uses R, Scala, and Ruby, but that’s not set in stone, and we value the ability to learn new libraries and ecosystems.
- Friendly and ready to work with others, both technical and non-technical. We don’t work in isolation and regularly interact with each other and members of other teams.
- At least some familiarity with: Unix-like operating systems, SQL databases, and web application programming. Strong experience in any is a plus.
- Other pluses: experience with distributed-computing ecosystems like Spark; experience with Amazon Web Services; experience teaching statistics or programming
Data Scientist Job Description: Example 5
We are looking for a teammate that is excited to take ownership of our data infrastructure and put us on a path where we are iterating quickly and using data to solve some of the biggest problems facing our industry. You will have a seat at the table in making technology decisions and in helping determine what and how we build things as opposed to just getting handed specifications to implement.
We’re looking for someone who is eager to disrupt an extremely archaic industry, but also enjoys startup perks, happy hours, and afternoon ping pong showdowns. We’re a small but quickly growing organization, so every single person here has a mission critical impact on our business.
- Take ownership and lead product development for our internal data processing pipeline
- Perform analysis and generate models to improve our automated data extraction capabilities
- Prototype, test and build models that will be adapted for use in our production data pipeline
- Work closely with the engineering team to advise on system architecture and help guide engineering priorities
- Build and lead a team of analysts and data scientists
- Deepen our culture of data driven decision making
- 18+ months of NLP, Data Science, ML professional work
- Experience specifying and building clean and functional data pipelines
- Comfort manipulating and analyzing complex, unstructured, data from various sources
- Ability to communicate complex quantitative analysis and approaches clearly
Experience with the following would be awesome
- Named Entity Recognition
- Dependency Parsing
- Semantic Role Labeling
- Probabilistic String Matching
- Elasticsearch, Apache Spark
