Job Description

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.

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 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
