竞赛编程专家 - 自由AI训练师
Competitive Programming Expert - Freelance AI Trainer
请提交你的英文简历，并注明你的英语水平。
Mindrift将专家与面向领先科技公司的基于项目的AI机会连接起来，专注于测试、评估和改进AI系统。参与方式为项目制，不是正式雇佣。
此机会涉及的内容
我们正在构建用于训练高级AI编码模型的竞赛编程问题及其自动评分系统（测试用例+检查器）。你将创建问题，编写正确和故意错误的解决方案，并设计能捕捉细微错误代码的测试用例。你的工作使训练信号变得可信。
申请时请提供：你的竞赛编程账号+当前/最高评级，任何出题经验，以及IOI/ICPC/奥赛经历。
你将负责
- 编写原创算法问题——清晰的问题描述，合理的约束条件，以及预期的解决方案；
- 用C++和Python编写正确的解决方案；
- 编写真实的错误解决方案（常见错误）以进行测试；
- 构建并强化测试用例：生成器、边界情况、压力测试和“黑客”测试；
- 为有多个正确答案的问题编写检查器/交互器（testlib）；
- 确保质量标准：正确的解决方案通过，错误的方案失败，在时间限制内完成。
我们寻找的人选
- 强大的竞赛编程背景，通过公开资料展示——Codeforces评级（见下文等级），或IOI/ICPC/国家奥赛记录；
- 流利的竞赛C++（STL、复杂度）；熟悉编写Python；
- 能解释为什么一个解决方案是错误的，并构造一个能破坏它的输入；
- 强大的书面英语能力（C1+）。
等级（根据Codeforces评级或同等奥赛成就）：
- 助理级 — 1700–2100（专家/候选大师）：较容易的问题；
- 专家级 — 2200–2600（大师/大师）：较难的问题；
- 高级/评审级 — 2600+（国际大师）或IOI/ICPC奖牌获得者：最难的问题+质量评审。
加分项
- IOI/ICPC校友及顶尖竞赛程序员特别鼓励申请；
- 具有为真实比赛（Codeforces赛事、ICPC、国家奥赛、在线评测系统）出题或测试的经验；
- 有Testlib经验（检查器、验证器、生成器）；
- 有为LLM代码基准或类似RL/评估数据集创建数据的经验。

Mindrift connects specialists with project-based AI opportunities for leading tech companies, focused on testing, evaluating, and improving AI systems. Participation is project-based, not permanent employment.
What this opportunity involves
We're building competitive-programming problems and their automatic graders (test cases + checkers) used to train advanced AI coding models. You'll create problems, write both correct and deliberately-wrong solutions, and design the tough test cases that catch subtly-broken code. Your work is what makes the training signal trustworthy.
To apply, share: your competitive-programming handle(s) + current/peak rating, any problem-setting experience, and IOI/ICPC/olympiad history.
What you'll do
- Write original algorithmic problems — clear statement, sound constraints, an intended solution;
- Write correct solutions in C++ and Python;
- Write realistic wrong solutions (common mistakes) to test against;
- Build and harden test cases: generators, edge cases, stress and "hacking" tests;
- Write checkers/interactors (testlib) for problems with more than one valid answer;
- Confirm the quality bar: correct solutions pass, wrong ones fail, within time limits.
What we look for
- Strong competitive programming background, shown by a public profile — a Codeforces rating (see levels below), OR an IOI / ICPC / national-olympiad record;
- Fluent contest C++ (STL, complexity); comfortable writing Python;
- Can explain why a solution is wrong and build an input that breaks it;
- Strong written English (C1+).
Levels (by Codeforces rating, or equivalent olympiad achievement):
- Associate — 1700–2100 (Expert / Candidate Master): easier problems;
- Expert — 2200–2600 (Master / Grandmaster): harder problems
- Senior / Reviewer — 2600+ (Int'l Grandmaster) or IOI/ICPC medalist: hardest problems + quality review.
Nice to have
- IOI / ICPC alumni and top competitive programmers especially encouraged to apply;
- Experience setting or testing problems for real contests (Codeforces rounds, ICPC, national olympiads, online judges);
- Testlib experience (checkers, validators, generators);
- Experience creating data for LLM code benchmarks or similar RL / evaluation datasets.
How it works
Apply → Pass qualification(s) → Join a project → Complete tasks → Get paid
Project time expectations
For this project, tasks are estimated to require around 10-20 hours per week during active phases, based on project requirements. This is an estimate, not a guaranteed workload, and applies only while the project is active. Tasks must be submitted by the deadline and meet the listed acceptance criteria to be accepted.
Compensation
Paid per accepted task. Your rate depends on the qualification tier you reach and how efficiently you complete tasks — up to the equivalent of $90/hr. Because payment is per task, a faster pace raises your effective hourly rate.
