Software Test & Validation Engineer (SQL / Database Testing)

Hemisphere Talent Solutions is seeking Software Test & Validation Engineers for its talent pool supporting US-based technology, engineering and enterprise clients. You will verify that full-stack applications work correctly, securely and in line with required standards.

You will work remotely as part of US project teams, reporting to the client's manager and working in the client's systems. You will combine white-box testing of the code with black-box testing from the user's perspective, and test against compliance and regulatory requirements.

• Design and execute test plans, test cases and test scenarios for full-stack web and mobile applications, covering the user interface, APIs and back-end services.
• Perform white-box testing: review code, write and run unit and integration tests, and test internal logic, code paths and error handling alongside developers.
• Perform black-box testing: functional, regression, integration, end-to-end, exploratory, boundary and negative testing from the user's perspective.
• Carry out compliance testing against client, industry and regulatory requirements, such as accessibility, security, data privacy and audit standards.
• Validate that software meets documented requirements, and maintain traceability from requirements to test cases and results.
• Build and maintain automated UI and API test suites, and integrate them into CI/CD pipelines.
• Test REST and SOAP APIs and the integrations between systems.
• Log, track and retest defects, and produce clear test reports and validation evidence for release sign-off.
• Collaborate with US developers, product owners and QA teams in Agile sprints.

• Degree or diploma in Computer Science, Information Technology or a related field, or equivalent professional experience.
• 3–7 years of software testing experience on web or full-stack applications.
• White-box testing: able to read code and write unit or integration tests in at least one of Java, C#, Python or JavaScript/TypeScript.
• Black-box testing: strong test design, plus regression and end-to-end testing.
• Hands-on test automation with Selenium, Playwright or Cypress.
• API testing with Postman, REST Assured or similar.
• Experience of compliance or standards-based testing, including producing test evidence and documentation.
• Familiarity with Jira or Azure DevOps, Git and CI/CD pipelines.
• Understanding of Agile/Scrum and the software development lifecycle.
• Strong attention to detail and professional English communication.
• Willingness to work overlapping US business hours.

• You will be a fixed-term employee of Hemisphere Talent Solutions' South African entity, with your contract matched to the client project.
• You will work remotely from a checked home setup or from our Johannesburg office, using client-managed devices and secure access. Hemisphere does not hold client data.
• The selection process includes a practical SQL and test-design assessment, followed by client interviews.
