Remote Code Review Engineer — AI Model QA & Debugging

AI Trainer Jobs; United States; Remote; USD 124,000 - 220,000; Full time

Benefits offered by this job

Remote work

Job summary

AI Trainer Jobs is seeking a Mechanical Engineer for a remote engineering review track focused on evaluating production code, debugging traces, and developer-facing AI outputs against real-world correctness standards. Reviewers reproduce failures, write the unit tests the model should have written, and explain the fix to help the modeling team target the gap.

Engineering model quality hinges on whether generated code compiles, passes tests, and handles edge cases.

Qualifications

• Strong day-job engineering experience with ability to read, run, and debug unfamiliar code.
• Ability to write concise unit tests that capture a single failure mode.
• Experience with a testing framework such as pytest, Jest, or JUnit.
• Clear written reasoning to convincingly present reviewer notes to a senior engineer.

Responsibilities

• Run and reproduce candidate code outputs in a sandboxed environment for Mechanical Engineer assignments.
• Grade mechanical engineer engineering review 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.
