How to Get a Job in Data Science: Required Education and Skills

To get a job in data science, you’ll need to learn statistics, mathematics, machine learning, deep learning, and artificial intelligence. Learning data science takes time and effort, but a data scientist’s salary and job security can make it worthwhile.

This data science career guide breaks down how to get a job in data science, including the job outlook, necessary skills, available education pathways, and tips to help you nail your job interviews. Let’s dive in.

What Is Data Science?

Data science is a multidisciplinary field in which statistics, probability, algorithms, and scientific methods are used to extract insights from structured and unstructured data. The technical skills you need include knowledge of mathematics, machine learning, deep learning, business intelligence, and computer science, to name a few.

When you’re in a data science role, you’ll handle every aspect of the data lifecycle, including data mining, cleaning, organizing, manipulating, and interpreting. The data science field has ample opportunities for career development, but you’ll need strong analytical skills to succeed.

Data Science Job Outlook

While the Bureau of Labor Statistics (BLS) doesn’t report on data scientists specifically, we can refer to computer and information research scientists for the job outlook. BLS predicts a growth rate of 22 percent in the supply of computer and information science jobs between 2020 and 2030. The median salary is $126,830 per annum.

What Education Do I Need to Become a Data Scientist?

The possible education pathways for data science include coding bootcamps, online data science courses, and bachelor’s and master’s degree programs. Regardless of the education you choose, hands-on experience is what really matters.

Can I Get a Data Science Job Without a Degree?

Yes, you don’t need an advanced degree to get a data science job. You might find the odd job description requiring a degree in data science. However, most potential employers value refined technical skills, real-life experience, and strong business acumen more than a degree.

Can a Coding Bootcamp Help Me Get a Job in Data Science?

Data science bootcamps are popular in the data science community because they equip students with all the necessary skills they need to start a career in the field. Coding bootcamps are much cheaper and quicker than degree programs and offer the chance to gain hands-on experience.

Like a degree program, coding bootcamps offer knowledge about machine learning, linear algebra, artificial intelligence, and related fields. Many bootcamps also expand your career opportunities by providing career support, including interview preparation, resume building, and soft skills.

How Long Does It Take to Get a Job in Data Science?

Depending on your previous experience and chosen education pathway, it can take from two to five years to break into data science. With a combination of job experience in data science and a coding bootcamp or associate degree, it can take you from two to three years.

Without previous experience or qualifications, you can opt for a bachelor’s degree, which means you’ll need about four to five years to gain the necessary data science skillset and be able to secure a job. Regardless of the path you choose, keep in mind that recruiters and interviewers seek out candidates with a combination of job experience and high-quality skills.

Common Data Science Education Paths

To launch a successful career in data science, you can join coding bootcamps, a community college, or a four-year degree program. Each learning pathway has its own set of pros and cons. Below are the most common education routes to get a job in data science. 

Data Science Bootcamps

In the data science field, employers are highly fond of coding bootcamps. Data science bootcamps offer short-term, intensive programs to help you become a successful data scientist through hands-on experience.

Coding bootcamps can be pricey for some aspiring data scientists, but many bootcamps offer financial aid and flexible payment options. Some job listings for data science might even include coding bootcamps as an education requirement. Plus, this option is cheaper than degree programs.

Community College

Many entry-level data scientists have chosen community college because it’s much cheaper than four-year degrees, and they only take two years to complete. You can find an online community college, and they may offer accelerated degree options as well. Data science employers will accept an associate degree if you have extensive real-world experience.

Although community college is cheaper than four-year degrees, these colleges are still much more expensive than coding bootcamps. Community colleges are also more expensive for out-of-state students. Fortunately, as an aspiring data scientist, you only need a high school diploma or GED to study.

Data Science Degrees

Data science degrees are common among senior data scientists. Degree programs offer skills as well as networking opportunities. A bachelor’s degree requires four years of studying, and a master’s degree requires two additional years of study.

Securing an entry-level job after graduation is easier with a college degree, but these programs are also more expensive. Many students have to opt for student loans to fund their studies, which can hinder your career in the long run.

Key Data Science Skills to List on Your Resume

If you want to win over the hiring manager with your resume, make sure you personalize it for the specific job posting and highlight essential data science skills. These include statistics skills, knowledge of a few programming languages, and machine learning skills. Below are some vital data science skills for your resume.

Statistics Skills

Statistical analysis and mathematical skills are pivotal for data science resumes. To work with data samples, predictive analytics, and business analytics, and to draw accurate conclusions from data, you need to learn statistics.

Without statistical skills, you won’t be able to land a data scientist job. If your skills in this area are lacking, consider online tutorials and short courses to master them.

Programming Languages 

Although you don’t need to know every programming language, you should know coding languages relevant to data science. These include Python, R, Java, Scala, JavaScript, and SQL. Experienced data scientists need to know several programming languages to provide optimal services.

There are many practical applications for data science programming languages. For example, JavaScript is used for data visualization techniques, Python is used for data manipulation, and R has a handy range of coding libraries for data science. 

Machine Learning Skills

Almost every company requires a data scientist with advanced machine learning skills. This is because data scientists use machine learning to analyze data and automate data modeling processes. To accomplish business goals, you need to work as efficiently and effectively as possible, and machine learning makes this possible. 

To build a successful data science career, you’ll need to learn machine learning and add this to your resume so employers know you can get the job done. Most if not all data science projects require this skill.
