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 ap
