UK Based Software Engineers (COBOL)

AI Trainer Jobs; United States; Remote; USD 179,000 - 234,000; Part time

Job summary

AI Trainer Jobs is seeking contributors to join a remote engineering review track for UK COBOL tasks. You will reproduce candidate code outputs in a sandbox, grade solutions for correctness, and write minimal failing tests to demonstrate defects.

This is a contractor-level, remote position with US eligibility and compensation of $130-$170 per hour. Successful reviewers bring strong debugging and unit-testing skills, plus clear written reasoning.

Qualifications

• Read, run, and debug unfamiliar code for COBOL tasks.
• Write concise unit tests that capture a single failure mode.
• Familiarity with a testing framework (pytest/Jest/JUnit, etc.).
• Clear written reasoning to convince a senior engineer.
• Reliable 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.
• Grade UK-based software engineers' review 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.
• Triage a security issue surfaced by a model and document the patch the model should have produced.

Job description

About the role

UK Based Software Engineers (COBOL) 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.

What you should bring

• Strong day-job engineering experience - you can read, run, and debug unfamiliar code for UK Based Software Engineers (COBOL) 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 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.

Compensation and schedule

$130-$170 / hr
Expected arrangement: contractor , with program-defined task volume and review pacing. Placement depends on current program demand and reviewer confirmation.
