AI Trainer Jobs; United States; Remote; USD 165,000 - 193,000; Full time

Job summary

AI Trainer Jobs is seeking a Front-end Developer (TypeScript) for a remote, contractor track that evaluates TypeScript code, debugs traces, and reviews 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. Deep TypeScript experience and ability to read, run, and debug unfamiliar code are essential.

Qualifications

• Strong day-job TypeScript experience with ability to read, run, and debug unfamiliar code.
• Ability to write concise unit tests capturing a single failure mode.
• Familiarity with a testing framework (pytest, Jest, or JUnit).
• Clear written reasoning to convince a senior engineer.
• Reliable async availability for at least 10 hours per week.
• Prior code-review or technical-interview-grading experience is a plus.

Responsibilities

• Run and reproduce TypeScript code outputs in a sandboxed environment.
• Grade TypeScript 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.
