What data scientists do
Data scientists are reasonably new kids on the block, taking huge sets of data, which can be both sorted and unsorted, and analyzing it for trends and meaning. Their role involves converting this data into comprehensive reports for organizations, which they can then utilize and implement within their strategy.
Data scientists draw upon different skills to perform this complex role. They need to use mathematics, information technology, statistics, industry knowledge and socio-economic theory to make sense of complex information and influence leaders in developing meaningful business solutions.
The role of data scientists might look different across separate organizations and industries, but the following is a list of what the job generally involves:
- Developing systems and algorithms to efficiently export data and present it to stakeholders
- Develop statistical techniques and use machine learning to develop solutions to problems
- Communicate data, results, and analytics clearly to facilitate people’s understanding of complex information
- Create detailed, logical, and engaging reports that will bring data and findings to life
- Work with areas which don’t effectively use data, developing ways to analyze information
- Research different ways to collect data, determining which are best for your needs
- Staying on top of data science trends and techniques
- Influence and negotiate with organisational leadership
- Recruit, train, and motivate a team of junior scientists
What the job is like
Data science is typically an office job, so you can expect a reasonably normal work-life balance. Nevertheless, there are some nuances to the role you should be aware of before embarking on this career.
Work environment
Data scientists are often office-based but may also work from home or undertake hybrid working. As the role involves delivering and interpreting complicated data to organisational leaders, there might be a need for frequent face-to-face meetings. Therefore, a reasonably high degree of presence will also be needed.
Unless the specific data science role is field based (e.g., working for some governmental organizations, law enforcement or roles requiring overseas deployment), your place of work will be an office.
You might need to spend long hours in server rooms, which are kept cold. Therefore, there might be a small risk of exposure to low temperatures. The role can be influential and reasonably senior, so there will be associated stressors which come with operating at this level.
Work hours
Data scientists can have a good work-life balance, beginning work around 8am and finishing around 6pm, Monday to Friday. There might be extended hours from time to time, and ad-hoc project work requiring longer shifts, but most data scientists can expect to receive this back as overtime or time in lieu. More senior data scientist roles might have to work longer, in line with other members of leadership. In these cases, there might be an expectation to stay as long as is needed to get the work done.
Job satisfaction
Data science offers high job satisfaction levels compared to other related fields, and ranked second in Glassdoor’s list of top jobs in the US for 2021, only behind Java developer. The reasons for this are a happy mix of factors, including decent work-life balance, high earning potential, high engagement and influence at work, and better socialization opportunities compared to other technology jobs.
Job market
The combination of rising salaries and a popular profession often leads to an oversaturated job market. Data science certainly fits this bill, but the immediate term outlook is positive for jobseekers. Burtch Works research shows that 81% of data science teams were recruiting for roles at the end of 2021.
The world is using more and more data. As different industries and companies undergo greater, and more urgent, change to adapt, data science continues to be in more demand than ever before. Companies which have never hired data scientists are starting to create job openings and even kickstart whole new divisions to benefit from their expertise.
Like many technology jobs, the data science market is becoming international, not just local. Firms wanting to hire top talent can now recruit data scientists from anywhere in the world, thanks to the ease of remote working.
Another consideration is that whereas data science is a popular, and dare we say it, ‘trendy’ field, the initial glut of people trained and ready to take jobs has passed. Organizations are competing heavily for a finite supply of qualified data scientists. This not only creates earning power for employee, but also means that data scientists can be lured by a competitor for more money.
