A Career in big data

The DASCA view of the rapidly changing and expanding big data career landscape serves as clear loud hints on how professionals, employers, and educators should prepare themselves for leveraging the phenomenal big data promise.

HOME Career in Big Data

A range of Big Data professions has emerged in the last ten years to help global data factories rebuild themselves into producers of Business Intelligence for corporations, government agencies, and other organizations. Though at their core, all technical Big Data professions still retain their traditional flavor, the methods and the tools of managing data have changed dramatically – as the scale, complexity, volume, velocity, and variety of data keep exploding through the roof – both, confounding, and exciting decision-makers at the same time.

  • The global big data analytics market size was valued at USD 307.51 billion in 2023 & is projected to grow from USD 348.21 billion in 2024 to USD 924.39 billion by 2032.
  • Over 53% of organizations are into big data, and 95% of those businesses need systems to evaluate unrecognized data.

The transformation of data into Big Data has not only added to the complexity of conventional data jobs, but it has also generated new categories of interdisciplinary roles – and created an era of several new Big Data career tracks – many of these demand multidimensional skills and competencies.

The following are the most important Big Data careers to have emerged in the last decade:

Data Science

Data Science

A career in data science is rewarding and lucrative since the demand for and availability of individuals with data-driven decision-making and data science skills has skyrocketed. It is an interdisciplinary field that uses scientific algorithms, processes, methods, and systems to extract insights from a broad range of AppDomains. Since 2012, the data science industry has witnessed a massive hike of 650 % far outpacing other industries.

Data science professionals require essential technical and non-technical skills such as evaluation of data, understanding the data structure, analyzing and visualizing data, writing concise codes, and most importantly work as part of a team.

These professionals also architect the analytics ecosystem required to convert petabytes of Big Data into solid chunks of Business Intelligence for corporations and governments.

The top job roles in data science are:

  • Data Scientist
  • Computer Vision (CV) Engineer
  • MLOps Engineer
  • Machine Learning Scientist

The demand for data science professionals is expected to increase by 28% by 2026.

Big Data Engineering

A career in Big Data Engineering is one of the most talked-about in the technology industry as this field deals with storing big data correctly and safely, thereby interacting with massive databases and data processing systems in large-scale computing environments.

Organizations facing a data deluge, with large data lying around in multiple formats require data engineering professionals to build big data reservoirs and fault-tolerant distributed systems to process and store rapidly changing data streams.

Professionals in this field require Hadoop, Machine Learning, NoSQL, NLP, Statistical Modeling, and Python development skills to design, code, program, and build specialist software applications used in handling and managing Big Data.

Furthermore, these professionals work with IT teams and big data architects on formulating project goals along with designing predictive models, top-tier algorithms, and prototypes.

The top job roles in this field are:

  • Statisticians
  • Computer Programmers
  • Computer and Information Research Scientists
  • Big Data Engineers

Over 70% of companies globally will be hiring big data engineering professionals to handle massive data as they will shift from big to wide data by 2025

Big Data Architecture

Big data architecture is a foundation for big data analytics. It is an overarching system used to handle large amounts of data so that it can be evaluated for steer data analytics, business purposes, and provide an environment in which data analytics tools can extract important business information from ambiguous data.

Big data architecture is designed to manage the processing, ingestion, and evaluation of data that is complex for traditional database systems.

Professionals in this field are responsible to provide the framework that replicates the needs of big data of an organization using skills to operate data, software, and hardware, cloud services such as Hadoop, MapReduce, oozie, MongoDB, and several other IT infrastructures to align the IT assets of a company with its business goals. Furthermore, these professionals work with domain experts to stay on track and put together a delivery plan.

The top job roles in big data architecting are:

  • Full-Stack Data Engineer
  • Python Developer
  • SQL Developer
  • Hadoop Architect

The demand for big data architecting professionals is expected to increase by 9% than the average of all other occupations in big data between 2018 –2028

Big Data Architecting
Big Data Administration

Big Data Administration

A career in Big Data Administration is high in demand as businesses require professionals to take care of the entire infrastructure and manage all the tools related to the big data ecosystem.

Professionals in this field are responsible for erecting, managing, and maintaining the infrastructure and ecosystem of a Big Data management setup. They blend their networking, Linux OS, Unix knowledge and skills in server administration, security, network planning with their exposure to data management processes to also handle clustering, segregation, distribution, mobility, and transfer of inbound and throughput data to ensure data keeps reaching intended points without disruption, contamination, and risk.

The top job roles in big data administration are:

  • Database Administrator
  • Hadoop Administrator
  • SAP HANA Administrator
  • DevOps Administrator

Approximately 700k Big Data Administrators are required worldwide in 2026 if we are to leverage the Big Data promise to its fullest.
