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

Job summary

AuraOne is seeking a Cross-Platform Engine Developer (Cocos2d-x) for a remote contractor role. You will evaluate production code, debug traces, and AI outputs, reproducing failures and explaining fixes to guide the modeling team.

Responsibilities include running candidate code in a sandbox, grading for correctness and style, and drafting minimal failing tests with clear rationale. Strong testing framework familiarity is essential.

Qualifications

• Strong day-job engineering experience; you can read, run, and debug unfamiliar code.
• Comfort writing concise unit tests that capture a single failure mode.
• Familiarity with testing frameworks: pytest, Jest, JUnit; Go test, RSpec, etc.
• Clear written reasoning that convincingly explains reviews to 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 candidate code outputs in a sandboxed environment for Cross-Platform Engine Developer (Cocos2d-x) assignments.
• Grade cloud & platform 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.

Job description

Cross-Platform Engine Developer (Cocos2d-x) is a remote engineering review track for evaluating production 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.

Category: Coding, SWE & Agent Evaluation · Pay: $50–$120 / hr · Location: Remote — US-eligible · Contractor

About the role

Cross-Platform Engine Developer (Cocos2d-x) is a remote engineering review track for evaluating production 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.
Engineering model quality lives or dies on whether the generated code actually compiles, passes tests, and handles edge cases. AuraOne pairs experienced engineers with the modeling team to grade outputs the way a code reviewer would.
Judge generated code and software engineering agents. Read their debugging traces.

Responsibilities

• Run and reproduce candidate code outputs in a sandboxed environment for Cross-Platform Engine Developer (Cocos2d-x) assignments.
• Grade cloud & platform 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.

What you should bring

• Strong day-job engineering experience — you can read, run, and debug unfamiliar code for Cross-Platform Engine Developer (Cocos2d-x) work.
• Comfort writing concise unit tests that capture a single failure mode.
• Familiarity with a testing framework. pytest, Jest, or JUnit. Go test, RSpec, or whatever you use.
• Clear written reasoning — your review note has 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.

Role signals

Example tasks

• Reproduce a generated engineering solution to a coding task, run the test suite, and grade it.
• Write the smallest failing test that demonstrates a model's edge-case bug.
• Compare two paired solutions and rank them with a written rationale tied to the rubric.
• Triage a security issue surfaced by a model and document the patch the model should have produced.

Useful experience

• Open-source contributions or a public portfolio that demonstrates production-quality code.
• Experience with the target language's standard tooling, linters, and idiomatic style guides.
• Familiarity with security-review checklists (OWASP, CWE) and AppSec patterns.

Compensation and schedule

$50–$120 / hr
Expected arrangement: contractor , with program-defined task volume and review pacing. Placement depends on current program demand and reviewer confirmation.
