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

Job summary

AuraOne, Inc. seeks a Rust Architect / Backend Developer for AI code evaluation. You will reproduce Rust solutions, run tests, and assess correctness, style, and edge cases. You’ll draft minimal failing tests and provide written rationales to guide improvements. This is a remote contractor role with US eligibility.

You will collaborate with the modeling team to target gaps and ensure high-quality code evaluation workflows. Strong Rust skills and test-focused mindset are essential.

Qualifications

• Strong day-job Rust experience; read, run, and debug unfamiliar Rust code.
• Ability to write concise unit tests capturing a single failure mode.
• Familiarity with a testing framework (pytest, Jest, JUnit, Go test, RSpec, or equivalent).
• Clear written reasoning; should convince a senior engineer.
• Available for at least 10 hours per week (remote contractor).

Responsibilities

• Reproduce Rust code outputs in a sandboxed environment for AI code evaluation tasks.
• Grade Rust solutions for correctness, style, and edge-case handling.
• Write minimal failing tests that demonstrate bugs.
• Compare paired solutions with a rubric-based written rationale.
• Tag failure modes with severity scores and document recurring issues.
• Calibrate reviews against gold standards to maintain consistency.

Job description

Rust Architect / Backend Developer — AI Code Evaluation is a remote engineering review track for evaluating Rust 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

Rust 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 Rust code outputs in a sandboxed environment for Rust Architect / Backend Developer — AI Code Evaluation assignments.
• Grade rust 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 Rust experience — you can read, run, and debug unfamiliar code for Rust Architect / Backend Developer — AI Code Evaluation 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 Rust 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 Rust's standard tooling, linters, and idiomatic style guides.
• Familiarity with security-review checklists (OWASP, CWE) and AppSec patterns.
