Java Developer

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

Job summary

AI Trainer Jobs seeks a Java Developer for a remote engineering review track evaluating Java 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. This is a remote role for US-eligible contractors with hourly compensation.

Qualifications

• Strong day-job Java experience — you can read, run, and debug unfamiliar code for Java Developer work.
• Comfort writing concise unit tests that capture a single failure mode.
• Familiarity with a testing framework (JUnit, pytest, Jest, etc.).
• Clear written reasoning — your review note has to convince another senior engineer.

Responsibilities

• Run and reproduce Java code outputs in a sandboxed environment for Java Developer assignments.
• Grade Java 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.

Role details

About the role

Java Developer is a remote engineering review track for evaluating Java 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.
Java 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 Java code outputs in a sandboxed environment for Java Developer assignments.
• Grade java 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.

What you should bring

• Strong day-job Java experience — you can read, run, and debug unfamiliar code for Java Developer 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 Java 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 Java'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.
