Backend Engineer (Coding Agent Experience)

AuraOne; United States; On-site; USD 97,000 - 138,000; Full time

Job summary

AI Trainer Jobs is seeking a Backend Engineer (Coding Agent Experience) to remotely review production code, debugging traces and AI outputs for correctness. You will reproduce failures, write unit tests, and explain fixes for the modeling team, focusing on code that compiles and passes tests.

Ideal candidates have strong programming experience, can write concise tests, and communicate their debugging reasoning clearly.

Qualifications

• Strong day-job engineering experience — you can read, run, and debug unfamiliar code for Backend Engineer (Coding Agent Experience) 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 equivalents.
• 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 candidate code outputs in a sandboxed environment for Backend Engineer (Coding Agent Experience) assignments.
• Grade backend 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

About the role

Backend Engineer (Coding Agent Experience) 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 Backend Engineer (Coding Agent Experience) assignments.
• Grade backend 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.

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.
