IsoData; United States; Remoto; USD 152.000 - 303.000; Tempo pieno

Descrizione del lavoro

IsoData is seeking mathematicians and statisticians to craft problems with verified solutions and to grade proofs and statistical reasoning. This remote, United States–based role is project-based with hourly pay from $110 to $220 per hour, paid per accepted task.

Applicants must reside in the US and be authorized to work in the United States. You would write original problems with a single checkable answer, grade proofs step by step, review statistical claims, and design rubrics that reward

Competenze

• Study at or graduated from a college or university in mathematics, statistics or related field.
• Proof, analysis or modeling work you did yourself and can explain step by step.
• You write clear proofs and can find the gap in someone else’s argument.
• Care with assumptions, edge cases and notation.

Mansioni

• Write original problems with a single checkable answer and a full worked solution, such as a counting problem whose answer is one exact integer.
• Grade model proofs step by step and mark the first wrong step, such as an inequality applied in the wrong direction.
• Review statistical claims for invalid inference, such as stopping a test early or running many comparisons without a correction.
• Check model derivations numerically, for example by testing a closed form against a quick simulation.
• Write rubrics that give credit for a correct method, not just a matching final answer.

Descrizione del lavoro

Remote, United States. Project-based.

For mathematicians and statisticians who can write a problem with one right answer, and show why it is right. Write hard problems with verified answers, and grade proofs and statistical reasoning.

Pay: $110 to $220 an hour, paid per accepted task. There is no guaranteed project, task volume, hours or pay.

You must live in the US, be at least 18 and be authorized to work in the United States. We accept applications on an ongoing basis.

What you would do

• Write original problems with a single checkable answer and a full worked solution, such as a counting problem whose answer is one exact integer.
• Grade model proofs step by step and mark the first wrong step, such as an inequality applied in the wrong direction.
• Review statistical claims for invalid inference, such as stopping a test early or running many comparisons without a correction.
• Check model derivations numerically, for example by testing a closed form against a quick simulation.
• Write rubrics that give credit for a correct method, not just a matching final answer.

The minimum

• You study at or graduated from a college or university in mathematics, statistics or a related field.
• Proof, analysis or modeling work you did yourself and can explain step by step, such as a thesis, a research project or a hard problem you solved and wrote up.
• You write clear proofs and can find the gap in someone else’s argument.
• Care with assumptions, edge cases and notation.

Ideal

• A degree in mathematics or statistics; a master’s or PhD is even better.
• Research, teaching at university level or professional quantitative work, especially at an AI lab or AI company.
• Publications, or national or international competition results such as the Putnam or an olympiad.
• Fluency in LaTeX and in a computing tool such as Python, R or Mathematica.

This position covers

Pure mathematics, Applied mathematics, Statistics and probability, Experiment design, Competition mathematics, Operations research.
