Data science is a multidisciplinary field combining math, statistics, and computer science with business insights. The term was coined in finance, so naturally, it has been associated with this field for a long time. Today, it has spread everywhere. But thanks to its broad scope, you can apply data science to almost all industries.
While this creates more opportunities for data scientists and businesses, it also increases the scope of knowledge and capabilities specialists need to succeed. Apart from analytical and technical skills, you need a good understanding of the chosen industry for your data career – from basic terminology to the latest developments.
So, although it isn’t necessary to know which field you want to work in at the beginning of your career, it’s helpful to narrow down your choices.

Data Science in Healthcare
Data is an integral part of all areas of medicine. In fact, the healthcare sector accounts for over 30% of the global data volume. Just imagine the amount and variety of information available from clinical trials, electronic health records, disease registries, etc.
This creates many opportunities. Data science applications in healthcare are numerous – from predictive testing to creating wearables and detecting anomalies in patient data.
Do data science jobs in healthcare sound exciting?
You can learn how to acquire such employment in our detailed guide on How to Become a Data Scientist in Healthcare.
Now, let’s look at the next sector.
Data Science in the Oil and Gas Industry
With a staggering profit of nearly $3 billion daily, the oil and gas sector is one of the world’s most significant—making it the perfect arena for data scientists.
Using insights from big data, data scientists can help optimize operations, reduce errors, and bring maintenance costs down. But this involves working with certain sources and types of information you won’t encounter elsewhere, such as drilling data and well logs.
So, to become a data scientist in the oil and gas industry, you must have a good grasp of the basic operations in this sector. You’ll also need a specific set of technical skills and knowledge to run experiments and simulations.
Data Science in Big Tech Companies
The Big Five tech giants (FAANG) are arguably the top companies for a data scientist.
Amazon, Netflix, Google, Meta, and Apple use data science to improve user experience, build personalized recommendation systems, create innovative solutions, etc.
Becoming a data scientist in a Big Tech firm requires a lot of hard work, but it’s well worth it in the end. There’s a reason why they are considered the top data scientist companies. Not only do they offer big salaries, but they’re also at the forefront of innovation.
Data Science in Telecom
The telecommunication industry generates massive amounts of data types every minute, including customer information, call details, network data. As a data scientist in this sector, you must be able to manage all of it.
For that purpose, you’ll need a firm grasp of the different areas of data science and solid domain knowledge, which slightly differs depending on the company you work for—e.g., satellite, telephone, internet service provider.
Still, the basic skills and knowledge you need to become a data scientist in the telecom industry fall within the same scope.
Data Science in Agriculture
Agriculture may not be the most obvious choice for a data science job, but there are many applications for such employment. A company, for example, could hire a data scientist to analyze soil, yield, and weather data to help improve production.
A data scientist’s role in agriculture companies could also involve developing data pipelines for automation and scalability, building machine learning models to predict weather conditions and plant diseases, etc. Again, domain knowledge and analytics skills are essential to becoming a data scientist in agriculture.
Now, let’s continue with a few more typical industries looking for data science specialists.
Data Science in the Insurance Industry
Insurance companies are just one example of the application of data science in finance.
Data scientists working in the insurance sector must be familiar with the basic terminology and recent developments, which will aid them when performing tasks like risk modeling, customer segmentation, lifetime value prediction, etc.
This aligns with the traditional perception of data science specialists, like in the tech sector.

Data Science in Cybersecurity
Cybersecurity deals with preventing global cybercrime. Data scientists can aid those efforts by creating models to understand the patterns of malicious activities and eventually predict them.
One thing is for sure – if you follow this career path, you won’t be left without your bread and butter. The demand for data scientists in this field is huge. The number of attacks and breaches has increased by 15% from 2020 to 2021 – and they’re getting harder to detect.
To catch up with cybercriminals, employers in the cybersecurity sector are looking to hire more data scientists. If you become a data scientist in cybersecurity, you won’t be disappointed.
Data Science in Retail
The role of a data scientist in retail can give companies a competitive advantage—helping to understand, for example, customers’ needs and wants.
Retailers all over the world are hiring data scientists to improve customer service, optimize production, and reduce losses. To succeed in this field, you need business knowledge and technical skills, such as how to build customer churn prediction models.
