Remote Java Code Review & Debugging Specialist

AI Trainer Jobs; United States; Remote; USD 69,000 - 165,000; Full time

Job summary

AI Trainer Jobs seeks a Java Developer for a remote engineering review track evaluating Java code, debugging traces, and developer-facing AI outputs against real-world correctness standards.

Reviewers reproduce failures, write the unit test the model should have written, and explain the fix so the modeling team can target the gap. This is a remote role for US-eligible contractors with hourly compensation.

Qualifications

• Strong day-job Java experience — you can read, run, and debug unfamiliar code for Java Developer work.
• Comfort writing concise unit tests that capture a single failure mode.
• Familiarity with a testing framework (JUnit, pytest, Jest, etc.).
• Clear written reasoning — your review note has to convince another senior engineer.

Responsibilities

• Run and reproduce Java code outputs in a sandboxed environment for Java Developer assignments.
• Grade Java engineering solutions for correctness, style, and edge-case handling.
• Write minimal failing tests that demonstrate the bug a model output missed.
• Compare paired solutions and rank them with a written rationale tied to the rubric.
• Tag failure modes (compile error, runtime crash, off-by-one, security issue) with severity scores.
