A data quality engineers job is to ensure that the data used in an organization or business is accurate, reliable, and up-to-date. They are responsible for maintaining the integrity of data systems and optimizing them for maximum efficiency. Data quality engineers leverage a range of technologies to carry out their duties—from software such as SQL and R to other tools like automation scripting. Data quality engineers must have a strong command of both analytical skills and technical knowledge in order to identify problems with existing datasets as well as design effective strategies for improving accuracy, reliability, timeliness, validity and completeness of structured/unstructured datasets.

A data quality engineer can give back by volunteering in many different ways. Some examples of how a data quality engineer could volunteer include: 1. Participate in open source projects related to data quality and analytics. Contributing code, bug fixes, feature suggestions or even just providing feedback can make a big difference for existing open source initiatives. 2. Join initiatives that work on improving the availability and accuracy of public datasets, such as OpenStreetMap or other civic-oriented open datasets. This type of effort requires strong technical skills but also offers great potential for the betterment of society at large since these types of efforts directly benefit everyone who uses those datasets (think navigation apps). 3.
