Job summary

AI Trainer Jobs is seeking a Staff Ruby Engineer for a remote engineering review track. You will evaluate Ruby code, reproduce failures, write unit tests, and explain fixes so the modeling team can close gaps.

The role emphasizes code quality, test coverage, and clear reasoning for senior engineers. Responsibilities include running Ruby outputs in a sandbox, grading solutions for correctness and edge cases, and writing minimal failing tests.

Qualifications

• Strong day-job Ruby experience; ability to read, run, and debug unfamiliar Ruby code.
• Experience writing concise unit tests that reveal a single failure mode.
• Familiarity with testing frameworks (RSpec, pytest, Jest, JUnit, Go test).

Responsibilities

• Run and reproduce Ruby outputs in a sandboxed environment for assignments.
• Grade Ruby engineering solutions for correctness, style, and edge cases.
• Write minimal failing tests that demonstrate bugs a model produced.
• Compare paired solutions and provide written rationale tied to rubric.
• Tag failure modes with severity and document patches.

Job description

Role details

Staff Ruby Engineer is a remote engineering review track for evaluating Ruby 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.

Staff Ruby Engineer is a remote engineering review track for evaluating Ruby code, debugging traces, and developer-facing AI outputs against real-world correctness standards.

About the role

Staff Ruby Engineer is a remote engineering review track for evaluating Ruby 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.
Ruby 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 Ruby code outputs in a sandboxed environment for Staff Ruby Engineer assignments.
• Grade ruby 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.Track Code review & evaluation Work model Remote Independent specialist contractor Compensation Hourly rate confirmed after the interview process. Eligible from US

What you should bring

• Strong day-job Ruby experience — you can read, run, and debug unfamiliar code for Staff Ruby 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.

Role signals

Example tasks

• Reproduce a generated Ruby 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 Ruby's standard tooling, linters, and idiomatic style guides.
• Familiarity with security-review checklists (OWASP, CWE) and AppSec patterns.

Compensation and schedule

Hourly rate confirmed after the interview process.
Expected arrangement: contractor , with program-defined task volume and review pacing. Placement depends on current program demand and reviewer confirmation.
