Job summary

Executive Staff Recruiters / ESR Healthcare seeks highly skilled coding puzzle solvers for a global remote AI training project. You will tackle self-contained coding and reasoning tasks, exploring unfamiliar codebases, selecting algorithms, and delivering reproducible solutions in a suitable language.

The role emphasizes independent work in terminal environments, rigorous testing, and clear communication of decisions and trade-offs. Flexible hours and weekend work optional.

Qualifications

• Strong algorithmic problem-solving ability.
• Proficient in at least one general-purpose language such as C++, Python, Java, Rust, Go, C#, JavaScript, or TypeScript.
• Solid understanding of data structures and algorithms.
• Ability to reason 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.

Responsibilities

• 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

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 skilledcoding puzzle solversto 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

1. Solve self-contained coding, logic, debugging, and technical reasoning challenges.
2. Analyze unfamiliar problems and translate their requirements into implementable solutions.
3. Select appropriate algorithms, data structures, and problem-solving strategies.
4. Work inside terminal-based development environments and existing codebases.
5. Implement correct and efficient solutions using an appropriate programming language.
6. Identify ambiguous requirements, edge cases, hidden assumptions, and failure conditions.
7. Debug incorrect behavior across code, tests, dependencies, and environment configuration.
8. Develop tests and verification methods that distinguish genuinely correct solutions from superficially plausible ones.
9. Review AI-generated solutions and identify logic errors, incomplete reasoning, and constraint violations.
10. Produce clear, reproducible solutions that can be executed and evaluated automatically.
11. Explain reasoning, implementation decisions, and trade-offs clearly

Required Qualifications

1. Strong algorithmic problem-solving ability.
2. Proficiency in at least one general-purpose programming language, such asC++, Python, Java, Rust, Go, C#, JavaScript, or TypeScript.
3. Strong understanding of common data structures and algorithms.
4. Ability to reason carefully about constraints, complexity, edge cases, and correctness.
5. Experience debugging unfamiliar code or solving technically ambiguous problems.
6. Ability to work independently in terminal-based development environments.
7. Ability to produce reproducible, testable software solutions.
8. Clear written and verbal technical communication.
