1. What is a QA Engineer at First Source?

A QA Engineer at First Source plays a pivotal role in maintaining the integrity, accuracy, and efficiency of the company’s business process outsourcing operations. Unlike traditional software-only quality assurance, a QA Engineer here is often deeply embedded in domain-specific workflows—such as U.S. Mortgage processing, healthcare insurance claims (BCBS), and revenue cycle management. Your work ensures that the services delivered to clients meet rigorous performance standards and regulatory requirements.

You will be the gatekeeper of operational excellence, monitoring key performance indicators to ensure that every process remains compliant and optimized. The position requires a blend of technical testing acumen and a keen understanding of business metrics like DSAT (Dissatisfaction Score), CSAT (Customer Satisfaction), and SLAs (Service Level Agreements). It is a role that demands high attention to detail and the ability to bridge the gap between technical data analysis and real-world business outcomes.
