What is Big Data?
Voluminous and complicated data sets that cannot be processed by traditional data processing application software is popularly known as Big Data. Let’s learn about the Big data jobs around us.
Due to its size, some of the challenges in handling Big Data include capturing, storage, analysis, search, transfer, querying, visualization updating and maintaining information privacy.
The three main dimensions of Big Data are Volume, Variety, and Velocity. Now it is also being used to refer user behavior analytics, predictive analytics, and certain other types of advanced data analytics methods through which value is extracted from data. Effective analyses of extensive data sets help find newer correlations of business trends, disease prevention and also fight crime. Big Data is now becoming particularly useful for medical practitioners, entrepreneurs and scientists alike for meeting daily challenges with humungous data sets in the realm of Internet search, fintech, urban informatics, business informatics, e-Science work, like meteorology, genomics, physics simulations, biology connectomics, and environmental research. The multi-faceted nature of Big Data has led to innumerable career opportunities that any aspiring individual can grab for a lucrative future and bright prospect.

Big Data jobs have been created in almost all industries like marketing, banking/investment banking, finance, games, etc. as per employment statistics. Some of the biggest names in the industry where one can tap for lucrative opportunities are IBM, Dunnhumby, SAS, Amazon, Google, Price Waterhouse Coopers, SAP, Accenture, Sopra Group, British Airways, Barclays, Amadeus Software, Aviva, Base 3 Systems Ltd, CSP, Capital One, Department for Work and Pensions etc.
Types of Big Data jobs
A number of roles are available in the Big Data industry and it can be put into two major categories:
- Big Data Engineering jobs revolve around designing data, deployment, maintenance and acquiring a huge amount of data. Big Data engineers need to design and make data available to consumers and internal applications.
- Big Data Analytics profiles include analyses of trends and patterns, prediction, classification, and forecasting form the duties in Big Data Analytics jobs. As per Forbes, Big Data analytics market will cross the $200 billion level soon.
Therefore, Big Data Analytics is computations on data while Big Data Engineering is the designing, deployment, and structuring of systems.
A senior executive at Accenture Institute for High Performance, Jeanne Harris spoke about the importance of analytics professionals and mentioned, “…data is useless without the skill to analyze it.” Big Data Engineering and Analytics today has more job opportunities when compared to last year and to get there, many IT professionals are willing to invest both money and time in receiving relevant training.
Qualifications for landing up with data analysis jobs
Here are some of the skills that would give you good Big Data jobs:
- Apache Hadoop- Big Data Hadoop jobs are positioned for a leap since software vendors are increasingly targeting processing architecture and distributed storage. Hadoop can be difficult but those who are in Hadoop developer jobs and are proficient technicians will know how to deal with core components of the Hadoop stack like HDFS, Flume, MapReduce, Hive, Oozie, Pig, YARN, and HBase. There are Hadoop jobs for freshers are also quite available for those who might know the advanced concepts but know Java, as Hadoop is written in Java.
- Machine Learning and Data Mining- The ability to train and build predictive analytic apps like the recommendation, classification, and personalization systems are in high demand and can fetch a high paying job.
- Statistical and Quantitative Analysis- If you are proficient in quantitative reasoning, statistics or mathematics, and have expertise in a statistical tool like Stata, Matlab, SAS, SPSS or R, getting Big Data jobs would be a breeze.
- General Purpose Programming Languages- If you have any prior experience of programming applications in general-purpose languages like Python, C, Java, or Scala, you would definitely have an edge over the other candidates whose skills are not beyond that of only analytics. As per Wanted Analytics, there was an increase of 337% in job postings for “computer programmers” requiring a background in data analytics. Aspiring candidates who are comfortable with the development of traditional applications and the emergence of analytics would be able to get high paying jobs with ease.
- SQL- This data-centric language is quite old but still has enough potential in this age of bog data. Though it is not used for handling the Big Data challenges, the simplified Structure Query Language turns out to be a no-brainer for most. Due to initiatives like Cloudera‘s Impala, SQL is being revived and becoming popular for the next-generation of Hadoop-scale data warehouses.
- Hadoop Spark- Hadoop Spark has risen rapidly in-memory stack and is being considered to be much simpler and faster when compared to MapReduce-style analytics- this could be inside or outside a Hadoop framework. Hadoop Spark is one of the major components in a Big Data pipeline and a lot of technical knowledge and know-how is required to program and run it. This by itself opens up a number of job opportunities for those who have sound knowledge and a certain amount of expertise.
