Are you a person who is planning to switch into the field of Analytics but is confused about what roles you want to pursue your career in? Well, you are at the right place. This article is targeted at a newbie audience who is planning to make a move into this field. We have collated the different roles in Data science and analytics, the skill sets required for the role, and the nature of the respective role’s work. In the earlier article, we have explained the life cycle of data science and recommend reading it.

Before attempting some hard-and-fast role definitions of these data science careers, let us start by sketching out the different task sets you typically find on a data science team. The idea here is to scope the high-level competence areas that need to be covered on a data science team, regardless of who carries out which task.

The three main data science careers are:

Mathematics/Statistics
Computer Science
Business domain knowledge.

Competence areas are needed on a data science team.

The image above shows the easy part because there’s general agreement on which competencies are required for a successful and efficient data science career though you still need to define the roles and areas of responsibility for each team member. The definitions of the data science career that you find here aim to give you a general understanding of the most important roles you will need on your data science team. Remember that variants may apply depending on your specific setup and strategic focus.

Some companies require you to know all the skills of all these positions, but as your team grows at your company, you may find that certain people will focus on their strengths to ultimately solve the most problems with Data Science and therefore become specialized in one of the roles below.

Business Analyst
Database Administrator
Big Data Engineer/Data Architect
Data Analyst
ML Engineer
Business Intelligence (BI) Developer
Business Intelligence Analyst
Statistician
Data Scientist
Computer Vision(CV) Engineer
Natural Langauge Processing(NLP) Engineer
MLOps Engineer

Business Analyst

The role of business analysts is slightly different from other data science jobs. While they do have a good understanding of how data-oriented technologies work and how to handle large volumes of data, they also separate the high-value data from the low-value data. In other words, they identify how Big Data can be linked to actionable business insights for business growth.

Although many of their job tasks are similar to that of data analysts, business analysts are experts in the domain they work in. They try to narrow the gap between business and IT. Business analysts provide solutions that are often technology-based to enhance business processes, such as distribution or productivity.

Organizations need these “information conduits” for a plethora of things such as gap analysis, requirements gathering, knowledge transfer to developers, defining scope using optimal solutions, test preparation, and software documentation.

Roles & Responsibilities:

Business analysts identify business needs, crystallizing the data for easy understanding, manipulation, and analysis via clear and precise requirements documentation, process models, and wireframes. They identify key gaps, challenges, and potential impacts of a solution or strategy.
In a day, a business analyst could be doing anything from defining a business case or eliciting information from top management to validating solutions or conducting quality testing. Business analysts need to be effective communicators and active listeners, resilient and incisive, to translate tech-speak or statistical analysis into business intelligence.
They use predictive, prescriptive, and descriptive analyses to transform complex data into easily understood actionable insights for the users. A change manager, a process analyst, and a data analyst could be doing business analysis tasks in everyday work.

Skills Required:

Apart from a degree in business administration in the field of your choice, healthcare or finance, aspiring business analysts need to have knowledge of data visualization tools such as Tableau and requisite IT know-how, including database management and programming.
You could also major in computer science with additional statistics, organizational behavior, and quality management courses. Or you could get professional certifications such as the Certified Business Analysis Professional (CBAP®) or PMI Professional in Business Analysis (PBA). Many universities offer degrees in business intelligence, business analytics, and analytics. Check out the courses in the U.S/India.

How to Become a Business Analyst?

Business analysts act as a link between the data engineers and the management executives. So, they should understand business finances and business intelligence, and also the IT technologies like data modeling, data visualization tools, etc

Database Administrator

The job profile of a database administrator is pretty self-explanatory- they are responsible for the proper functioning of all the databases of an enterprise and grant or revoke its services to the company employees depending on their requirements. They are also responsible for database backups and recoveries

Roles & Responsibilities:

Build database systems of high availability and quality depending on each end user’s specialized role
Design and implement database in accordance to end users’ information needs and views
Define users and enable data distribution to the right user in the appropriate format and in a timely manner

How to Become a Database Administrator?

Some of a database administrator’s essential skills and talents include database backup and recovery, data security, data modeling, design, etc. If you are good at disaster management, it is certainly a bonus.

Big Data Engineer

Knowledge of different programming and scripting languages is a non-negotiable skill. Usually, people with 1 to 3 years of experience handling databases and software development are preferred for an entry-level position.

Roles & Responsibilities:

Big data engineers develop, maintain, test, and evaluate big data solutions within organizations.
They are also involved in the design of big data solutions because of their experience with Hadoop [-] based technologies such as MapReduce, Hive, MongoDB, or Cassandra.
Big data engineers configure, use, and program big data solutions to support big data analysts and meet business requirements via customization and optimization of features.
Using various open-source tools, they “architect highly scalable distributed systems.” They must integrate data processing infrastructure and data management.
It is a highly cross-functional role. With more years of experience, the responsibilities in development and operations; policies, standards, and procedures; communication; business continuity and disaster recovery; coaching and mentoring; and research and evaluation increase.

Skills Required:

Big data engineers, who have computer engineering or computer science degrees, need to know:

Basics of algorithms and data structures, distributed computing.
Hadoop cluster management, HDFS, MapReduce.
Stream-processing solutions such as Storm or Spark
Big data querying tools such as Pig, Impala, and Hive, data integration
NoSQL databases such as MongoDB, Cassandra, and Hbase
Frameworks such as Flume and ETL tools
Messaging systems such as Kafka and RabbitMQ
Big data toolkits such as H2O, SparkML, and Mahout.
They must have experience with Hortonworks, Cloudera, and MapR.

How to become Big Data Engineer?

Broadly speaking, there are three distinct skill sets that must be reconciled in the data Engineer role.

Algorithms: You understand the theory of data science, the statistics, modeling rules, and mathematics that are at the heart of any data problem. You understand how experiments are designed and measured. You understand the algorithms and theory behind data science.
Engineering: You understand the engineering required to source, process, and store data. You should be aware of programming languages and distributed computing schemes that will help you deal with massive amounts of data at scale. You should understand the programming that applies your theories to massive datasets.
Communication: You understand how to communicate your solutions and how to relate those solutions to business problems.

The career path would be Data Engineer → Senior Data Engineer → BI Architect → Data Architect

Data Analyst

Languages like R, Python, and SQL are part of the data analyst’s basic knowledge. Much like the data scientist role, a broad skill set is also required for the data analyst role, which combines technical and analytical knowledge with ingenuity.

Roles & Responsibilities:

Data analysts are responsible for various tasks, including visualization, munging, and processing massive amounts of data.
They also must perform queries on the databases from time to time, looking into the key metrics of a business. They oversee data that is scraped, assuring the quality and managing it. They must interpret data and effectively communicate the findings.
Designing and deploying algorithms, culling information and recognizing risk, extrapolating data using advanced computer modeling, triaging code problems, and pruning data are all in a day’s work for a data analyst.
They also do presentations and work with stakeholders or non-technical stakeholders. It will be your responsibility to promote data literacy and emphasize the importance of your findings. The quality of the analysis is always paramount, but you will be evaluated mostly on the impact you are driving. This means that you always must ask, “So what?” to every insight your analysis reveals and, above all, make sure to communicate clearly what your analysis means to the end-user and what are your recommended actions.
They also do AB testing and significance testing, where they analyze the model’s output and decide if there has been enough impact to continue the current model process, enhance it with new features or metrics and set up experiments. The goal of this role is to save the company money and time and make the business more competitive.

Unlike data scientists, data analysts are more generalists. Udacity calls them junior data scientists. They play a gamut of roles, from acquiring massive amounts of data to processing and summarizing it. This role can have a lot of freedom in the ways that you drive impact. Any trend or insight you identify and convince decision-makers to act upon is a win.

The potential downside of this freedom is that you will often not have a single clearly defined question to pursue, which can cause a lack of focus or frustration because you are not sure what to work on. Developing a sense of priorities and the ability to identify high-impact projects will be key skills.

The word “Analyst” tends to have a more junior connotation, and hence many companies (especially in the technology sector) instead use “Data Scientist”. My advice would be to not pay much attention to the word used and instead focus on the job description, team, company, and, of course, the potential salary

Skills Required:

Data analysts are expected to know R, SAS, Python, HTML, SQL, C++, and Javascript. certification in these can easily give a boost to your job applications. You should also have good problem-solving qualities.
They need to be more than a little familiar with data retrieval and storing systems, data visualization, and data warehousing using ETL tools, Hadoop-based analytics, and business intelligence concepts.
Product sense, cross-discipline collaboration, AB testing, metric definition, data visualization, and stakeholder communication.
These persistent and passionate data miners usually have strong math, statistics, machine learning, and programming background.

How to Become a Data Analyst?

SQL, R, SAS, and Python are some sought-after data analysis technologies. So, certification in these can easily give a boost to your job applications. You should also have good problem-solving qualities.

Machine learning engineers are in high demand today. However, the job profile comes with its challenges. Apart from having in-depth knowledge of some of the most powerful technologies such as SQL, REST APIs, etc., machine learning engineers are also expected to perform A/B testing, build data pipelines, and implement common machine learning algorithms such as classification, clustering, etc. This is a highly desired role and can be behind some of the most user-facing applications the internet has to offer today, such as recommendations systems or Spotify’s Discover Weekly playlist.

Roles & Responsibilities:

To address business challenges, machine learning engineers must design and implement machine learning applications/algorithms such as clustering, anomaly detection, classification, or prediction.
ML engineers build data pipelines, benchmark infrastructure, and do A/B testing.
They work collaboratively with product and development teams to improve data quality via tooling, optimization, and testing. ML engineers must monitor the performance and ensure the organization’s reliability of machine learning systems.

Skills Required:

Engineers should focus on Python, Java, Scala, C++, and Javascript.
To become a machine learning engineer, you need to know to build highly scalable distributed systems, be sure of the machine learning concepts, play around with big datasets, and work in teams that focus on personalization.
ML engineers are data- and metric-driven and have a strong foundation in mathematics and statistics. They are expected to have experience in Elasticsearch, SQL, Amazon Web Service, and REST APIs.
In this role, you will sit between the data science and engineering realms: you need to have a great understanding of statistical and machine learning models and be able to implement a scalable backend solution to ship your model into production.
This role is much more technical than the product data analyst and can be even more technical than the modeling analyst. Like the modeling analyst, this role is usually situated within a team of other technical roles such as other MLEs and data scientists. The main performance indicator will be the quality of your backend work and the ML models you ship.
Machine learning models, statistics, back end engineering, the above three job categories likely cover most “traditional” data science jobs, but I think there is a new category of hybrid data scientist positions that are being created in response to the demand for data scientists that have data engineering and data visualization skills.
As always, great communication skills are vital to interpreting complex ML concepts to non-experts.

How to Become a Machine Learning Engineer?

Firstly, you must have a sound knowledge of some of the technologies like Java, Python, JS, etc. Secondly, you should have a strong grasp of statistics and mathematics. Once you have mastered both, it is a lot easier to crack a job interview.

Knowledge of Tableau or Power BI preferred — Excel and SQL skills are great. However, knowledge of next-generation tools will ease the transition to BI analyst. With advanced business analytics capabilities, Tableau and Power BI are renowned for their ability to identify data insights and create actionable reports.

Statistician

A statistician, as the name suggests, has a sound understanding of statistical theories and data organization. Not only do they extract and offer valuable insights from the data clusters, but they also help create new methodologies for the engineers to apply.

Statisticians collect, organize, present, analyze, and interpret data to reach valid conclusions and make correct decisions. They are key players in ensuring the success of companies involved in market research, transportation, product development, finance, forensics, sport, quality control, environment, education, and governmental agencies. A lot of statisticians continue to enjoy their place in academia and research.

The field of statistics has always been about number crunching. A strong statistical base qualifies you to extrapolate your interest in several data scientist fields. Hypothesis testing, confidence intervals, Analysis of Variance (ANOVA), data visualization, and quantitative research are some of the core skills possessed by statisticians which can be extrapolated to gain expertise in specific data scientist fields explained in the following section of this article.

When clubbed with domain knowledge (such as marketing, risk, and actuarial science), statistics knowledge is the ideal combination to land a statistician’s work profile. They can develop statistical models from big data analysis, carry out experimental design, and apply theories of sampling, clustering, and predictive modeling to available data to determine future corporate actions.

Roles & Responsibilities:

Using statistical analysis software tools, statisticians analyze collected or extracted data, trying to identify patterns, relationships, or trends to answer data-related questions posed by administrators or managers. They interpret the results and strategic recommendations or incisive predictions using data visualization tools or reports.
Maintaining databases and statistical programs, ensuring data quality, and devising new programs, models, or tools if required also come under the purview of statisticians. Translating boring numbers into exciting stories is no easy task!

Also, there is an overlap between Data Scientists and MLOps Engineers. They often work closely together to achieve the company’s ultimate goal of running a beneficial Machine Learning algorithm or Data Science model.

What role is right for you?

The above roles can be distinguished by an impact vs. methods vs. platforms trichotomy. If you are a talented data scientist interested in driving insights and impact on a particular product or part of the business, with less focus on the methodology and techniques used, then you might be more suited for the product data analyst or business intelligence positions.

If you are interested in always being near the nexus of the latest machine learning models and methods and are excited to apply them to your company’s vast data sources, then you might be better suited to the modeling analyst and machine learning engineer positions.
Finally, if you’re motivated by taking a more horizontal role in your organization, to educate and enable other teams to do their work better, then you might be interested in the data-services-as-a-platform roles, such as the platforms & tools developer.
If a job listing caught your eye and you aim to understand better what type of data science role it is, read the job description and try to see if they emphasize impact, methods, or platforms. Also, ask the hiring manager who your stakeholders will be and how your performance will be evaluated.
