Big data is the term used for the data, which is either too big, changes with a speed that is hard to keep track of, or the nature of which is just too complex to be handled by traditional data handling techniques. Big data is omnipresent, and every human on earth leaves a trail of data that encapsulates their online presence.

Due to the low computational power and the fear of missing out on some crucial insights, data generated was stored until the turn of this century, which is when this industry started gaining its footing in the world. The importance of the sheer volume of big data cannot be ignored. Google AI (which is found on every smartphone), advertisements that you see online, and all the various recommending engines (like Amazon and Netflix) are fueled by the big data you generate. 

Needless to say, Big data is transforming the world that we see and soon will take the driving seat in propelling the global economy. To suffice Big data’s growing nature, the need for trained personnel will only increase according to the U.S. Bureau of Labor Statistics (BLS). They estimate that career opportunities in big data will see a boom of about 12% by the end of the year 2028, creating more than 500,000 jobs.

Finding people with the right skill set is the real challenge due to the lack of people having the required expertise. Thus, increasing the pay of the people substantially who have the right skillset. Pursuing a big data career is a good option, especially if you possess the skills needed to be in the industry

Career in Big data: What career opportunities in big data are there, and what can you expect?

There is no denying the increase in the sheer strengths of the computers, and its presence, the data generated, has also increased. It is also estimated that almost 90% of the big data that we have has been generated in the past few years. To derive insights and use the data to our advantage, a number of job opportunities have opened in the big data sector.

So, listed below, you will find a few of the plethora of career opportunities in big data:

1. Big Data Engineer

Big data engineers are tasked with developing the solutions which the big data architect has designed for the company. They are supposed to be the backbone of the big data pipeline of any organization. They are the ones who maintain, create, develop, and simultaneously test the solutions that they build. A big data engineer’s toolkit must contain tools that are based on Hadoop technology like Hive MongoDB, MapReduce, or Cassandra.

Not only this, but a big data engineer should also have a profound knowledge of data warehousing solutions because they have to work in creating the required pipeline (from start to end), which is needed to process data on a large scale in any organization. They are generally also responsible for maintaining the hardware infrastructure, mainly ensuring that the team has enough processing power to tackle huge data volumes each day. If you think Big data engineering is your preferred career in big data, the money you would make would be in the range of 130K to 220K US dollars.

2. Data Architects

The main job of any data architect is to design and build intricate data frameworks like databases. They usually are a part of the team, which is called for whenever there is a need for databases. A data architect would look at the problem, the data that is available to them with its help they would create a blueprint. This blueprint which they have created would encapsulate all the phases that the database has to go through like, creation, testing, and how that database would be maintained.

The blueprint that these architects have created would then be passed onto the big data engineers who would do all the heavy lifting in implementing the architect’s vision. Data architects work with a variety of data, the data that they get can be personal records, the information which is used in marketing or financial records. They, however, also have to work alongside data administrators and data analysts to ensure that the architects are provided with all the data that they need. From this data, they would need to come up with the databases which would be used to store all the information in.

They also need to think in a way to make the stored data accessible based on the clearance that any user has, and create a fail-safe mechanism in case the company is attacked for ransomware or any natural calamity. All this information should be neatly presented in the blueprints that these data architects are responsible for. The big data architects make roughly in the range of 120K to 200K US dollars.

3. Data Warehouse Manager

The job of a data warehouse manager is to oversee the team, which is responsible for designing, maintaining, implementing, and supporting the systems designed for data warehousing.

A data warehouse manager can earn anywhere in the ballpark of 80-160K US dollars. 

4. Database Manager

A database manager is responsible for maintaining the database results by enforcing the standards, checks, and balances. They are the ones who prepare the database for expansion. They make sure that the database is ready for the development by studying the plans that there are and going through the requirements to ensure the process is as smooth as possible. They also advise the senior technical managers on the design and programming by coordinating with the technical management’s upper echelon.

Upgrading the piece of hardware and the software that the team has also falls under a database manager’s job category. They are supposed to devise policies, procedures, and controls that would ensure the databases’ safety and security. A good database manager would not only manage the databases but also would update his knowledge by continually participating in learning opportunities.

They should develop a habit of reading through tech publications and maintain an excellent professional circle. They should also have a keen eye on any new research in the field of data and think of the ways in which they can implement them at their workplace.
