Remote PHP Back-End Reviewer: Code Quality & Tests

AI Trainer Jobs; United States; Remote; USD 148,000 - 210,000; Part time

Job summary

AI Trainer Jobs is seeking a PHP Back End Developer for a remote contractor role to evaluate PHP code, debug traces, and assess 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.

PHP model quality lives or dies on whether the generated code actually compiles, passes tests, and handles edge cases.

Qualifications

• Strong day-job PHP experience, able to read, run, and debug unfamiliar code.
• Comfort writing concise unit tests that capture a single failure mode.
• Familiarity with a testing framework (pytest, Jest, JUnit, Go test, RSpec or equivalents).
• Clear written reasoning to convince another 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 PHP code outputs in a sandboxed environment for assignments.
• Grade PHP engineering solutions for correctness, style, and edge-case handling.
• Write minimal failing tests that demonstrate the bug an 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.
