Why this grade This listing scored 70/100, which is a B. It lost the most ground on pay transparency. See the breakdown
- Description depth 20 / 20 How much the posting actually says about the work, measured in characters of real text.
- Remote clarity 15 / 15 Whether "remote" means anywhere, or is quietly restricted to one country.
- Freshness 12 / 15 How recently it was posted. Older postings are likelier to be filled or abandoned.
- Pay transparency 12 / 25 A published salary range, worth more than any other single factor because it is what a candidate cannot find out without applying.
- Role specificity 6 / 10 Whether the listing is tagged well enough to tell what the role actually is.
- Corroboration 5 / 10 Whether more than one source carries this listing.
Every figure above is arithmetic over the posting itself — its salary field, its text, its age, its tags and how many sources carry it. How the grades work →
Mid level Contractor
Puzzle Solver (Coding)
Pay: $50–$80/hour
Location: Global, fully remote
Job Type: Contractor (~15 hours per week)
Schedule: Flexible—you choose the hours and days you work, including weekends if desired
We are looking for highly skilled coding puzzle solvers to contribute to an AI training project involving algorithmic reasoning, debugging, constrained technical problems, and reproducible software solutions.
The work involves solving self-contained coding and technical challenges designed to test the capabilities of advanced AI models. A representative task may require exploring an unfamiliar codebase or terminal environment, understanding a precise objective, implementing a solution, testing it against hidden or explicit constraints, and producing a reproducible final result.
What You’ll Work On
- Solve self-contained coding, logic, debugging, and technical reasoning challenges.
- Analyze unfamiliar problems and translate their requirements into implementable solutions.
- Select appropriate algorithms, data structures, and problem-solving strategies.
- Work inside terminal-based development environments and existing codebases.
- Implement correct and efficient solutions using an appropriate programming language.
- Identify ambiguous requirements, edge cases, hidden assumptions, and failure conditions.
- Debug incorrect behavior across code, tests, dependencies, and environment configuration.
- Develop tests and verification methods that distinguish genuinely correct solutions from superficially plausible ones.
- Review AI-generated solutions and identify logic errors, incomplete reasoning, and constraint violations.
- Produce clear, reproducible solutions that can be executed and evaluated automatically.
- Explain reasoning, implementation decisions, and trade-offs clearly
Required Qualifications
- Strong algorithmic problem-solving ability.
- Proficiency in at least one general-purpose programming language, such as C++, Python, Java, Rust, Go, C#, JavaScript, or TypeScript.
- Strong understanding of common data structures and algorithms.
- Ability to reason carefully about constraints, complexity, edge cases, and correctness.
- Experience debugging unfamiliar code or solving technically ambiguous problems.
- Ability to work independently in terminal-based development environments.
- Ability to produce reproducible, testable software solutions.
- Clear written and verbal technical communication.
A public or otherwise verifiable Codeforces profile demonstrating meaningful competitive-programming experience is nice to have.
Process
- Apply to the role and complete the screening questions.
- Complete an AI interview of approximately 30 minutes.
- Complete a technical assessment, if required.
- Complete the hiring manager review.
Compensation Structure
Compensation is output-based. Experts are paid per task that meets the project specifications. The time required to complete each task may vary depending on the expert’s experience and workflow.
Minimum submission requirements apply.
Start Timeline & Availability
- We typically fill roles within 48 hours and are looking for experts who are ready to begin immediately. If selected, you will be expected to start your first task within 24–48 hours of completing onboarding.
