Competitive Programming Expert – Freelance AI Trainer

Responsibilities

We are representing a confidential AI research organization that is building competitive-programming problems and automatic graders to train advanced coding models. As a Competitive Programming Expert, you will:

• Write original algorithmic problems with clear statements, sound constraints, and intended solutions
• Develop correct solutions in C++ and Python
• Create realistic wrong solutions that represent common mistakes to test against
• Build and harden test cases including generators, edge cases, stress tests, and adversarial inputs
• Write checkers and interactors for problems with multiple valid answers
• Validate quality: ensure correct solutions pass, wrong solutions fail, and all run within time limits

What We're Looking For

Required:

• Strong competitive programming background demonstrated by a public profile (Codeforces rating, IOI, ICPC, or national olympiad record)
• Fluent in competitive C++ (STL, complexity analysis) and comfortable writing Python
• Ability to explain why a solution is incorrect and construct inputs that expose failures
• Strong written English (C1+ proficiency)

Experience Levels (by Codeforces rating or equivalent):

• Associate: 1700–2100 (Expert/Candidate Master) for easier problems
• Expert: 2200–2600 (Master/Grandmaster) for harder problems
• Senior/Reviewer: 2600+ (International Grandmaster) or IOI/ICPC medalist for hardest problems and quality review

Preferred:

• IOI or ICPC alumni and top competitive programmers
• Experience setting or testing problems for contests (Codeforces rounds, ICPC, national olympiads, online judges)
• Testlib experience (checkers, validators, generators)
• Experience creating data for LLM code benchmarks or evaluation datasets

How We Work With You

This is a project-based freelance opportunity. Candidates apply through Get A Job.ai, where our talent team will screen your competitive programming profile, handle(s), current or peak rating, problem-setting experience, and olympiad history. After qualification, we submit you to our client. Please do not contact the client directly.

Active project phases are estimated at 10–20 hours per week. This is not guaranteed workload and applies only while the project is active. Tasks must meet acceptance criteria and deadlines.

Pay

Compensation is paid per accepted task. Your rate depends on your qualification tier and task completion efficiency. This role can reach the equivalent of up to $90 USD per hour for those who complete tasks at a faster pace.

Get A Job.ai is an equal opportunity recruiter. We welcome applicants of all backgrounds and do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
