Data Quality / Data QA Engineer Job Summary We are looking for a detail-oriented Data Quality Engineer / Data QA to ensure the accuracy, completeness, and reliability of our modern AWS-based data platform. You will act as the gatekeeper of data trust, bringing a deep understanding of financial data domains (spending, lending, deposits) to define comprehensive data quality rules from every angle. You will work closely with Data Architects, Data Engineers, Business Analysts, Data Governance, source-system teams, and business users to define data-quality requirements, rules, processes, and operational workflows. A strong understanding of data and business context is important, as the candidate will be responsible for defining and maintaining data-quality rules that cover different dimensions such as completeness, accuracy, consistency, uniqueness, validity, integrity, and timeliness. Key Responsibilities · Define and execute data-quality and data-validation checks across source systems, data pipelines, and target datasets. · Validate data completeness, accuracy, consistency, uniqueness, timeliness, and business-rule compliance. · Perform source-to-target reconciliation, record-count validation, duplicate checks, null checks, and transformation-rule validation. · Design and execute test scenarios for ETL/ELT pipelines across SIT, UAT, production deployment, and data backfill activities. · Investigate data discrepancies, work with Data Engineers and source-system teams to identify root causes, and track issues through resolution. · Develop reusable SQL-based or automated data-quality checks to improve testing efficiency and reduce manual validation. · Support production monitoring, incident investigation, data-quality reporting, and continuous improvement of data-quality controls. Qualifications · At least 2–4 years of experience in Data Quality, Data QA, ETL Testing, Data Testing, Business Intelligence Testing, or a related role. · Strong SQL skills for querying, validation, reconciliation, aggregation, and data analysis. · Experience with data-quality checks such as completeness, accuracy, uniqueness, consistency, validity, and timeliness. · Experience preparing test scenarios, test cases, expected results, and defect reports for data-related projects. · Ability to investigate data discrepancies and identify potential root causes. · Good communication and collaboration skills when working with Data Engineers, Business Analysts, source-system teams, and business users. Nice-to-Have · Experience working in banking, financial services, or another regulated industry. · Familiarity with AWS data services (e.g., S3, Athena, Glue, Redshift) and querying data directly from cloud storage. · Practical understanding of databases, data warehouses, data lakehouse, ETL/ELT pipelines, and data models. · Experience with data-quality frameworks, automated testing tools, or data-observability platforms. · Basic understanding of data governance, metadata, data lineage, data classification, and sensitive-data handling.

Here's how to pick the right one and stand out in your application.
144.883Jobs
31.687IN

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
