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 Type Script .

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 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.
