Position: Software Engineer, TypeScript — Codebase Q&A
Type: Contract
Compensation: $130 per approved task
Location: Remote
Role Responsibilities
- 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
Must-Have
- 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.
Preferred
- Experience with developer tooling, compilers, test frameworks, GraphQL servers, or state machines.
Compensation & Legal
- Payment is per approved task; every task is reviewed by a second engineer and a super reviewer before acceptance.
