Remote Code Review Engineer for AI Outputs & Tests

AI Trainer Jobs; United States; Remote; USD 160,000 - 190,000; Part time

Job summary

AI Trainer Jobs is seeking a Project Engineer for a remote contractor role focused on evaluating production code, debugging traces, and developer-facing AI outputs to ensure real-world correctness. Reviewers reproduce failures, write the unit test the model should have written, and explain the fix so the modeling team can target the gap.

Engineering model quality hinges on code compiling, tests passing, and proper edge-case handling.

Qualifications

• Strong day-job engineering experience — you can read, run, and debug unfamiliar code for Project Engineer work.
• Comfort writing concise unit tests that capture a single failure mode.
• Familiarity with a testing framework (pytest, Jest, JUnit, Go test, RSpec).
• Clear written reasoning — your review note must convince a senior engineer.
• Reliable async availability for at least 10 hours per week.

Responsibilities

• Run and reproduce candidate code outputs in a sandboxed environment for Project Engineer assignments.
• Grade project engineer 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 rubric-based rationale.
• Tag failure modes with severity scores.
