OneScreen is seeking a detail-oriented, analytical and proactive Software Quality Assurance Engineer to join our team in Pakistan. The ideal candidate will take ownership of the quality assurance process, going beyond standard testing procedures to help us deliver exceptional, reliable solutions to our customers.

The Role: What You'll Do

You will be responsible for the quality assurance of a dynamic web application whose core functionality relies on a chain of API calls to various AI services (ML, LLM, VLM). Your primary focus will be on API testing, load testing, and validating the correctness of AI model outputs.

• API Testing & Automation: Execute and automate testing for complex, multi-step API requests that feed into and retrieve results from our ML/LLM/VLM models.
• Performance & Load Testing: Assist in designing and executing load and stress tests to ensure the AI pipeline is fast, scalable, and stable under peak usage.
• AI Output Validation: Develop test cases focused on the quality, relevance, and accuracy of AI-generated content (e.g., checking for LLM hallucinations, VLM misclassification, and general bias).
• Functional Testing: Design and execute detailed test plans, test cases, and test scripts for the web application's user interface (UI) and end-to-end functionality.
• Bug Management: Identify, document, and track defects using a modern bug tracking system, working closely with the development team to ensure timely resolution.
• CI/CD Integration: Integrate automated test scripts into the continuous integration/continuous deployment (CI/CD) pipeline.
