Java Quality Assurance Lead

The work

As a Java Quality Assurance Lead, you will review AI-generated Java code and trainer QA work across Java AI training projects. You will judge work against project guidelines, write clear feedback, monitor contributor quality, and help maintain consistent standards.

You will also support Java review workflows, documentation, onboarding materials, and quality improvements for remote technical teams.

• Review Java code, Spring backend snippets, debugging answers, tests, architecture explanations, and step-by-step reasoning.
• Check compile-time validity, runtime behavior, object-oriented design, API use, debugging accuracy, readability, performance, security, and formatting.
• Review test coverage and assess whether technical explanations are correct and clear.
• Spot-check contributor work, escalate repeated issues, and help keep review guidelines consistent.
• Maintain Java style guides, FAQs, examples, calibration tasks, honeypots, trackers, and onboarding materials.
• Support onboarding, training, and quality communication for remote Java contributors.

About AI training work

AI training is the human work behind systems that generate and understand code, text, images, and other content. Reviewers assess examples and give precise feedback so models become more accurate, useful, and reliable; people with strong technical expertise are needed for specialist work such as Java code evaluation.
