Quality Assurance Engineer

Paysign is seeking a QA Engineer to own the quality of our payment processing and healthcare platform releases through a combination of manual testing and test automation. This role builds and executes test plans across web, mobile, API, and data/back-end layers, integrates automated checks into CI/CD pipelines, and partners with developers, data engineers, and product stakeholders to catch defects before they reach production. The position operates within a Cardholder Data Environment (CDE) subject to PCI-DSS requirements, so test data handling, environment segregation, and audit-evidence practices are integral to the role.

Making sure you fit the guidelines as an applicant for this role is essential, please read the below carefully.

Key Responsibility Areas

Test Planning & Manual QA

• Analyze requirements, user stories, and acceptance criteria to design comprehensive test plans, test cases, and test data
• Execute manual functional, regression, exploratory, and UAT-support testing across web, mobile, and back-end systems
• Validate business logic for payment, cardholder, and copay/healthcare workflows including edge cases and negative scenarios
• Verify fixes and perform root-cause-aware retesting; maintain traceability between requirements, tests, and defects

Test Automation (API / UI / Regression)

• Build and maintain automated test suites for APIs (REST) and UI using frameworks such as Playwright, Cypress, Selenium, Postman/Newman, or equivalent
• Grow and maintain a reliable regression suite, keeping tests deterministic, well-factored, and low-maintenance
• Implement data-driven and contract tests that validate request/response schemas between services
• Manage test data setup/teardown and environment configuration for repeatable automated runs

Data & Back-End Testing

• Write SQL to validate data correctness across MariaDB/MySQL and analytics sources (Redshift/Athena), including reconciliation and transformation checks
• Test ETL/ELT pipeline outputs, file loaders, and batch jobs for completeness, accuracy, and idempotency
• Validate reports and dashboards (e.g., Tableau) against source-of-truth data

Release Testing & CI/CD Integration

• Integrate automated tests into GitLab CI/CD pipelines and gate deployments on test results
• Perform smoke and sanity testing across environments (dev, test, stage, prod) as part of release promotion
• Coordinate release/regression cycles with developers and DevOps, and support rollback verification

Compliance & CDE Testing

• Ensure test data in non-production environments contains no real cardholder or PHI data; use masked, tokenized, or synthetic data per PCI-DSS and CDE rules
• Support security, penetration, and access-control testing efforts and capture audit evidence for PCI-DSS and SOC 2
• Follow CDE change-management and separation-of-duties controls in all testing and sign-off activities

Defect Management & Reporting

• Log, prioritize, and track defects in Jira with clear reproduction steps, severity, and expected vs. actual results
• Report test coverage, pass/fail trends, and release-readiness status to engineering and stakeholders
• Contribute to continuous improvement of QA processes, standards, and test documentation

Required Qualifications

• 3+ years of experience in software quality assurance (manual and automation)
• Hands-on experience building automated tests xhqgsiq for APIs and/or UI (Playwright, Cypress, Selenium, Postman/Newman, or equivalent)
• Strong SQL skills for data validation against relational databases
• Experience testing REST APIs and web/mobile applications
• Solid understanding of the SDLC, test methodologies, and defect lifecycle
• Experience integrating automated tests into CI/CD pipelines (GitLab CI preferred)
• Proficiency with a defect/test management tool (Jira or equivalent)
• Strong analytical skills and attention to detail with clear written communication

Preferred Qualifications

• ISTQB or similar QA certification
• Experience testing in PCI-DSS Cardholder Data Environments (CDE) or other regulated industries
• Experience testing data pipelines, ETL/ELT, or BI/reporting outputs (e.g., Tableau)
• Scripting proficiency in Python or JavaScript/TypeScript
• Experience with performance/load testing (JMeter, k6, or equivalent)
• Familiarity with AWS services (ECS, Lambda, S3, RDS)
• Experience in fintech, payment processing, or healthcare software
• Knowledge of SOC 2 controls and audit evidence practices
