Junior data scientists work on volumes of raw data early on in the processes. Collecting, organizing, validating, cleaning, and structuring data using code to further pass on to senior data scientists in the organization. At this level, aspiring data scientists are exposed to most data job functions, while honing programming skills and applied mathematics knowledge.
Years of experience and continued learning enables you to branch out as senior data engineers, senior data architects, ML engineers, business analysts, or continue to progress the data scientist’s career path.
#3: Business Intelligence Developer and Market Analysts
Entry-level data professionals are also given the job titles of Business Intelligence (BI) developers and market analysts. At an entry-level, BI developers work actively with various departments on real-time industry and company data. They must identify problems, market trends, evaluate business processes, and uncover valuable business insights. Thus, they need to be experts at data modeling and visualization tools like advanced excel to report findings.
A graduate with a business administration degree and a penchant for data can easily start their careers in this profile. However, to branch out into data analytics, market analysts must learn database skills and have thorough knowledge of applied mathematics as well as statistics.
Mid-level Roles for Data Science (Experience: 4–8 years)
A minimum of three years of experience as junior data scientist enables you to choose the field to build your data science career in. Larger enterprises and tech-driven companies have robust data development teams that comprise senior data analysts, senior data scientists’, data engineers, data architects, as well as AI and ML engineers.
#1: Senior Data Engineers and Architects
Senior data engineers and senior data architects work together to build data infrastructure, software, and frameworks to collect and manage terabytes of raw data. This data could be coming from varying sources into a centralized location. They are key to ensuring flawless data flow, modeling, and architecture of how data is captured, database management, security of data, data integrity, and data governance based on business goals.
#2: Senior Data Analysts
Senior data analysts are also business and market analysts with advanced expertise and business acumen. Organizations across industries rely on data analysts to collaborate with various departments to analyze big data, historical data, running A/B testing, and working with data visualization tools such as Tableau. Their reports and data analysis help C-suite leaders drive more revenue, find growth opportunities, and solve business problems.
#3: Senior Data Scientists and Data Science Managers
A senior data scientist’s work involves:
- Identifying trends and patterns across big data
- Building ETL pipelines for logical flow of data
- Leveraging deep learning
- Using ML to forecast data
- Graphically representing trends to various stakeholders
- Driving actionable insights
Senior data scientists build frameworks, write codes for businesses to automate processes, and deliver enhanced consumer experiences.
Take, for example, Uber’s data science workbench (DSW). Uber’s data development team worked extensively on developing an all-in-one toolbox that is today accessed by data scientists, engineers, and operations teams across the organization. More than 4000 active users leverage DSW for complex applications, such as pricing, safety, fraud detection, and customer support, among other foundational elements of the trip experience. It centralized everything required to perform data preparation, ad-hoc analyses, model prototyping, workflow scheduling, dashboarding, and collaboration in a single-pane, web-based graphical user interface.
Directorial Roles in Data Science (Experience: 8 – 12 years)
To progress from a senior data scientist’s role to the next level, professionals need to add advanced data science certifications and data science programs to their skill sets. Moreover, the job titles available with close to 12 years of expertise are lead data scientists, principal data scientists, and data science directors. Expect the average base salary at this stage to rise up to US $155,166 per year.
Senior data analysts, however, switch roles laterally or move up to job roles such as senior business analytics managers, business insight and analytics managers, director of analytics product managers, and some even move into specific data scientist roles. So, much would depend on the industries one has worked in and the scope of the projects one has handled. Salaries for such roles range from US$102,000 to US$124,000 per year.
