About the role
We create high-quality STEM training data for frontier AI models. Our work improves model reasoning in advanced technical domains and is used directly in training and evaluation pipelines at leading AI labs.
We are looking for Computer Science experts to design difficult, deterministic problems with exactly one verifiable correct answer, along with complete, verified solutions.
What you’ll do
Design advanced problems in algorithms, systems, theory, machine learning, or computational methods
Create code-first and reasoning-heavy tasks that challenge state-of-the-art AI systems
Submit complete and verified solutions, including programmatic approaches when needed
Develop multi-part tasks that mirror real technical and research workflows
Ensure problems are deterministic, rigorous, and reproducible
Write clearly and precisely in English
What we’re looking for
Bachelor's, Master’s or PhD in Computer Science or a related field
Strong research or industry experience in computational problem-solving
Strong Python skills; experience with scientific or ML tooling is a plus
Excellent understanding of algorithms, complexity, numerical methods, and software-based workflows
Ability to create hard, original problems beyond standard interview-style questions
Strong written communication and attention to detail
Nice to have
Experience in machine learning, formal methods, distributed systems, optimization, or scientific computing
Experience with benchmarking, evaluations, or technical assessment creation
Familiarity with advanced libraries, solvers, or symbolic systems
