Full Stack Software Engineer | $70/hr | Remote

Full Stack Software Engineer, 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
