AuraOne, Inc.; United States; Remote; USD 83,000 - 165,000; Part time

Job summary

AuraOne, Inc. is seeking a Senior Java Engineer for a remote contractor role in the United States. You will review Java code outputs, reproduce results in a sandbox, and write minimal failing tests to expose bugs for the modeling team.

You will grade solutions for correctness and style, document issues with clear rationales, and tag failure modes. Strong Java skills, familiarity with unit testing frameworks (JUnit or equivalents), and the ability to work asynchronously for at least 10 hours per

Qualifications

• Strong day-job Java experience — you can read, run, and debug unfamiliar code for Senior Java Engineer work.
• Comfort writing concise unit tests that capture a single failure mode.
• Familiarity with a testing framework (JUnit, pytest/Jest, or equivalent).
• 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.

Responsibilities

• Run and reproduce Java code outputs in a sandboxed environment for Senior Java Engineer 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.
• Document recurring code-generation failures so the modeling team can target them.
• Calibrate against gold-standard reviews to keep inter-rater agreement above target.

Job description

Senior Java Engineer 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.

Why this role matters

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.

Responsibilities

• Run and reproduce Java code outputs in a sandboxed environment for Senior Java Engineer 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.
• Document recurring code-generation failures so the modeling team can target them.
• Calibrate against gold-standard reviews to keep inter-rater agreement above target.

Qualifications

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

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.

Nice to have

• 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.
