Backend Engineer | $100/hr | Remote

Backend Engineers, API Developers & Secure Systems Specialists. Remote AI Project

We are seeking experienced Backend Engineers, API Developers, Distributed Systems Engineers, Platform Engineers, and Security-Focused Software Engineers to create realistic, challenging coding tasks that evaluate how advanced AI systems solve real software engineering problems.

What You’ll Do

• Create realistic backend software engineering tasks for AI systems to solve

• Design feature implementation challenges based on production-style services

• Create debugging and bug-fixing tasks

• Develop API-focused engineering scenarios

• Build tasks involving service logic, databases, concurrency, networking, and distributed systems

• Design security-focused backend tasks where relevant

• Implement deterministic verifiers and automated graders

• Ensure verifiers accept multiple reasonable correct implementations

• Ensure incorrect, partial, brittle, or shortcut solutions fail verification

• Create hidden test cases and edge cases

• Build golden reference solutions

• Review task difficulty, realism, and technical correctness

• Identify unintended shortcuts or exploitable grader behavior

• Debug test failures and environment issues

• Refactor task environments for reliability and reproducibility

• Review AI-generated code for correctness, maintainability, performance, and security

• Document task expectations and verification logic clearly
