Senior QA Engineer- ETL & API

As a Salesforce Summit Partner, we work in Healthcare, Life Sciences, Financial Services, Insurance, and Hi-Tech — industries where getting AI right matters and the tolerance for failure is low. Our delivery model is senior-heavy by design. The same team that scopes an engagement ships it to production. There are no junior shadow teams, no sub-contractors brought in when the problem gets hard, and no hand-off to a separate managed services vendor when the project closes.

We run an internal innovation practice that builds the reusable patterns, pre-tested architectures, and industry-specific frameworks that give every Teqfocus client a head start — and give every Teqfocus practitioner work that compounds over time.

We are a diverse, immigrant-entrepreneurial company. We were built on the conviction that the best outcomes come from people who take genuine ownership of what they build — and are trusted to do so.

Key Responsibilities

• Design and execute functional, integration, end-to-end, negative, boundary, and regression tests for RESTful APIs and associated business workflows.
• Build, enhance, and maintain reusable API test automation frameworks and regression suites using Java, JavaScript/TypeScript, or Python.
• Integrate automated testing into GitHub Actions, Jenkins, Azure DevOps, or equivalent CI/CD pipelines; investigate failures and improve test reliability.
• Validate microservices, asynchronous and event-driven integrations, listeners, message processing, data synchronization, and end-to-end data integrity.
• Verify JSON request/response payloads, schemas, field mappings, status codes, error handling, and backend records using SQL.
• Perform data and ETL testing, including source-to-target reconciliation, mappings, transformations, migrations, duplicate/missing record checks, and data-quality controls.
• Test MDM processes including matching and merging, survivorship rules, golden records, master data hierarchies, and duplicate detection.
• Prepare test strategies, scenarios, cases, test data, evidence, and requirements traceability; document defects, investigate root causes, and manage resolution in Jira or similar tools.
• Partner with developers, business analysts, and other stakeholders throughout Agile/Scrum delivery cycles.

Required Skills & Qualifications

• 5+ years of software quality engineering experience, with approximately 3–5 years of hands-on REST API testing across the test lifecycle.

• Hands-on experience designing and maintaining API automation frameworks and integrating regression tests with CI/CD.
• Strong SQL and backend data validation skills, including data comparison, reconciliation, duplicate detection, and source-to-target checks.
• Practical experience with functional, integration, regression, data/ETL, and end-to-end testing.
• Working understanding of MDM concepts: master records, hierarchies, match-and-merge, survivorship, golden records, and data quality.
• Experience testing microservices, asynchronous/event-driven systems, JSON payloads, schema validation, and error scenarios.
• Strong defect management, test documentation, analytical thinking, and communication skills within Agile teams
