Senior Backend Engineer (Python) [Remote]

AuraOne Human Data

Remote
  • Remote job

Senior Backend Engineer (Python) is a remote engineering review track for evaluating Python 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

Python 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 Python code outputs in a sandboxed environment for Senior Backend Engineer (Python) assignments.
  • Grade python 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 Python experience — you can read, run, and debug unfamiliar code for Senior Backend Engineer (Python) 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 Python 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 Python's standard tooling, linters, and idiomatic style guides.
  • Familiarity with security-review checklists (OWASP, CWE) and AppSec patterns.

Skills

  • Code review
  • Debugging
  • Unit testing
  • Software engineering judgment
  • Python engineering
  • Software engineering
