If you’re fluent in Java and you can explain why something works, not just that it compiles, this role puts you in the driver’s seat. You’ll challenge advanced AI models with real engineering problems, then document every failure mode so the model learns to reason cleaner, code safer, and debug smarter.
About Invisible
Invisible supports AI development by producing high-quality training data and expert evaluation workflows. They partner with technical specialists to validate outputs, identify failure patterns, and improve model reasoning for real-world software engineering use.
Schedule
Contract, freelance, remote (U.S. listed).
Hours vary based on your availability and project demand.
You provide a secure computer and high-speed internet connection.
What You’ll Do
⦁ Converse with AI models on software engineering tasks and technical scenarios using Java
⦁ Verify logical accuracy, Java fluency, and completeness of solutions
⦁ Assess code quality for clarity, maintainability, and secure coding practices
⦁ Capture reproducible error traces and document recurring failure patterns
⦁ Challenge the model on complex topics (async concepts, RESTful APIs, OOP design, debugging distributed systems)
⦁ Suggest improvements to prompts, evaluation criteria, and quality metrics based on what you observe
What You Need
⦁ Strong, practical Java experience in real-world environments
⦁ Solid CS fundamentals (algorithms, data structures, software architecture)
⦁ Comfort debugging and reasoning through complex system behavior
⦁ Ability to clearly explain reasoning and “show your work” in writing
⦁ High attention to detail and consistency when evaluating technical outputs
⦁ Degree in CS/Software Engineering (BS/MS/PhD) is ideal; open-source work, technical writing, or equivalent experience valued
Benefits
⦁ Flexible, remote contract work
⦁ Pay range of $8–$65/hour (rate based on experience, expertise, and location)
⦁ Hands-on work with cutting-edge AI tools and evaluation pipelines
⦁ Direct impact on model reliability, safety, and usefulness
⦁ Project-based opportunities that can expand with performance and availability
These roles reward people who are precise, consistent, and can write clean explanations without getting cute.
