Competitive Coder

$45–$65/h

Remote

Role overview

Job Title: Competitive Coder

Job Type: Contractor (15hrs+ a week)

Location: Remote


Job Summary: In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.


As an expert you will be creating Reinforcement Learning Environments which test an AI model’s ability to solve complex competitive programming problems. You will be tasked with creating a unique custom problem absent from all existing online judges, creating a reference solution and creating a robust test suite.


Key Responsibilities:

  1. Design and implement checkers for competitive programming problems with multiple valid outputs, ensuring accuracy and robustness.
  2. Evaluate and validate participant submissions against complex problem statements sourced from platforms like Codeforces.
  3. Collaborate with the customer's team to fine-tune problem requirements and clarify ambiguous scenarios.
  4. Develop clear, maintainable code in C++ to assess diverse outputs and edge cases efficiently.
  5. Document checker logic and communicate intricacies or edge cases in both written and verbal form.
  6. Provide feedback to problem setters and reviewers on potential improvements to test cases and checkers.
  7. Stay updated with evolving competitive programming standards and incorporate best practices into checker development.


Required Skills and Qualifications:

  1. Expertise in competitive programming and coding problem analysis.
  2. Advanced proficiency in C++ for implementing robust checker solutions.
  3. Strong analytical abilities to interpret complex problem constraints and multiple solution paths.
  4. Exceptional written and verbal communication skills; ability to articulate technical details clearly.
  5. Meticulous attention to detail in code validation and output consistency.
  6. Experience working independently in a remote, collaborative environment.
  7. Commitment to producing high-quality, well-documented code under tight deadlines.


Preferred Qualifications:

  1. Prior experience as a problem setter, tester, or checker on major competitive programming platforms.



Compensation Structure

Compensation is output-based; experts are paid per task that meets the project specifications. The time required to complete work may vary depending on the expert’s experience and workflow. Minimum submission requirements apply. Experts must submit a minimum of tasks per week.


Start Timeline & Availability

We typically fill roles within 48 hours and are looking for experts ready to jump in right away. If selected, we expect you to start your first tasks within 24–48 hours of completing onboarding.

How big is the remote / hybrid opportunity?

Remote work is already huge — but the bigger story may be the hundreds of millions of jobs that could still move beyond geography.

Global remote and hybrid work opportunity infographic

Remote work already connects millions of people with companies they would never have been able to work for a decade ago. But compared with the size of the global labour market, it may still be early.

The interesting number is not only how many people work remotely today — it is how many roles could plausibly become remote or hybrid next.

The chart above starts with roughly 3.3 billion people employed worldwide. Around 300 million jobs are already remote or hybrid, while an additional pool of roughly 250 million roles could potentially move in that direction as technology, workflows and company culture continue to change.

Skills are becoming more portable

This matters because more work can increasingly be matched to expertise rather than location. AI training and evaluation are a good example: companies need lawyers, engineers, designers, editors, researchers, finance professionals and many other specialists to help improve AI systems.

For workers, that creates access to projects outside their local market. For companies, it expands the talent pool from one city or country to the world.
