[Hiring] TypeScript Developer @Mercor

Role Description

• Select tasks from a pre-validated pool of TypeScript repositories, each pinned to a specific git commit and arriving with an engineering question, positive and negative rubrics, foils, and a golden solution.
• Explore the repository until you genuinely understand the subsystem in question, including the relevant PR or issue history.
• Rewrite the task's question so it defeats frontier coding agents while remaining well-defined and fairly answerable.
• Adjust rubrics and foils to reward correct reasoning and reject plausible-but-wrong answers.
• Run the full validation loop in Studio — Check, Golden, Run, Analyze — and iterate until every stage passes.
• Document your work in the task README and submit for expert review, addressing reviewer feedback on returned tasks.

Qualifications

• 3+ years of professional software engineering experience, with substantial production TypeScript.
• Demonstrated ability to navigate a large, unfamiliar TypeScript monorepo and explain how it behaves at runtime.
• Fluency in the advanced type system, module resolution, bundlers and transpilers, and the Node and browser runtimes.
• Precise written English: the questions and rubrics you write are the product.
• Comfortable with git at commit level, containerized environments, and command-line tooling.

Requirements

• Experience with developer tooling, compilers, test frameworks, GraphQL servers, or state machines.

Benefits

• Payment is per approved task; every task is reviewed by a second engineer and a super reviewer before acceptance.

Application Process

• Submit your resume or relevant technical background to get started.
• Qualified applicants may be asked to complete a brief technical assessment or provide additional information.
