Remote iOS Engineer; Coding Agent - AI Trainer

About the Role

Mercor is partnering with a leading AI research lab to support a Frontier Code Agents project. Contributors help evaluate and improve frontier AI coding models through structured technical assessments. The work focuses on realistic mobile engineering workflows and model evaluation rather than traditional software development. Spots are limited and filling quickly on a first come, first serve basis.

• Use frontier AI coding agents to complete and evaluate complex engineering tasks.
• Review model-generated mobile application code for correctness, quality, maintainability, and performance.
• Identify bugs, edge cases, and failure modes in model outputs.
• Compare outputs from multiple frontier models and assess their strengths and weaknesses.
• Apply professional engineering judgment to realistic mobile engineering scenarios.

Sprint based project that runs in 12-24 hour stretches based on client requirement.

• $400 per accepted task.
• Typical tasks take approximately 2–3 hours after ramp-up.
• Compensation is tied to accepted work.

• 2+ years of professional iOS engineering experience.
• Experience building and maintaining production iOS applications using Swift and modern iOS frameworks.
• Regular use of AI coding agents such as Cursor, Claude Code, Codex, Windsurf, Gemini CLI, or similar tools.
• Ability to evaluate model-generated mobile implementations and architectural decisions.
• Experience shipping production mobile applications is preferred.
