Building a data science career as a beginner. How can you do it?

The data landscape has changed over the years, increasing opportunities for people seeking data-related jobs in companies. Among the careers that one can work in is the data science field which uses algorithms to generate insights and help companies make better use of their data.

Even though the data science field is constantly changing, there are a few constant aspects that you must be aware of to succeed in the field. In this article, we will look into some insights on how you can build a successful data science career with a focus on education, skill development and job searching approaches.

Educational requirements

The debate on whether one needs a degree to be a data scientist or not has been ongoing for some time now. While education has always been touted as the best way to enter the data science field, many professionals became data scientists without undertaking a relevant degree like data science or computer science. Typically, data scientists are expected to have a bachelor’s degree in data science, mathematics, computer science or statistics among other related fields. Some employers might prefer people with master's or doctoral degrees in data science depending on the nature of the job. It is generally expected that with the relevant education, one can perform their duties optimally.

Data science as a field borrows heavily from computer science, statistics and mathematics. This means that a solid understanding of these three areas is key to deriving insights from the data, developing well-functioning models and analyzing data. Some courses that can greatly improve your performance as a data scientist are linear algebra, probability, statistics and calculus.

Apart from the formal education approach which entails getting a relevant bachelor’s and graduate degrees, one can also transition to data science through boot camps and online courses. Data science boot camps are very intensive programs that allow you to prepare for the data science field within a few months. These boot camps and courses like Coursera teach you the data science skills that you will need to succeed as a data scientist. With many boot camps and online courses coming up, you have to carefully choose your preferred course to align with your career goals.

The skills to master

A data scientist must possess both hard and soft skills to excel in their job. The hard skills that one must develop to become a better data scientist include mastering Python, R, SQL, statistics, data visualization, deep learning, machine learning, cloud computing, natural language processing and big data.

Soft skills are human skills that allow a person to work properly with their colleagues and clients, and they are not job-specific. Soft skills that one must possess include communication, critical thinking, problem-solving, storytelling and teamwork.

As an entry-level professional, mastering hard and soft skills may not be enough to get your first job. You will need a strong portfolio that shows your mastery of the hard and soft skills that you possess. As a data scientist, a good portfolio should focus on your abilities in handling real-world data problems, starting with acquiring the data, cleaning, analysis, model building and deployment of the model. A platform like GitHub is a good place to showcase your portfolio as you build your online presence.

Navigating the job market for data science roles

Some of the roles within the data science field are:

  • A data scientist focuses solely on building predictive models and deriving insights from data.
  • A data engineer is responsible for developing and maintaining the infrastructure for generating, storing and retrieving data.
  • A machine learning engineer is responsible for designing, implementing, and deploying machine learning models.

Securing a data science position involves using online job boards, networking and using direct applications. Sites like LinkedIn, Glassdoor, Fuzu or Brighter Monday can serve as a place for finding relevant job opportunities. Networking can also help a person get valuable job leads that can translate to jobs. After finding the relevant job opportunities, the next stage is to craft a compelling cover letter and resume that captures technical skills, the experience and also aligns it with the job requirements.

Career growth as a data scientist

As a practicing data scientist, there are various activities that you can engage in to further grow as a data scientist. Some of these activities include networking, seeking new mentors, joining a data science community and keeping updated on new developments in the data science field.

Networking is key for a data scientist’s career growth. Avenues for networking include attending industry events, engaging data science communities on platforms like X or LinkedIn and joining professional groups. Networking with peers and mentors offers professional opportunities for career growth.

As an increasingly changing field, keeping abreast of new changes by continuing education or reading research papers will keep you informed of new techniques, tools and best practices that will make you competitive in your field.

Conclusion

A career in the data science field requires a good educational foundation, mastery of specific soft and technical skills and also continuous professional development to remain competitive in the dynamic field. This article has looked at some of the important aspects that aspiring data scientists can do to position themselves for success in the field. As stated in this article, the data science field is dynamic and therefore you should do more research and reading to understand
