Role Overview
Design verifier-backed reasoning tasks for advanced STEM evaluation and post-training refinement of frontier models.
Karokan is working with AI labs and deployment teams across Europe to contract high-judgment specialists who can improve model quality through reliable human input. This role is designed for experts who can translate nuance into structured outputs, work with clear evaluation rules, and contribute directly to the performance of production AI systems.
You will operate in a fully remote setting, collaborate asynchronously, and help shape datasets, reviews, and decision layers that support the next generation of AI products. The work is intentionally rigorous: accuracy, consistency, and written reasoning matter more than generic throughput.
Key Responsibilities
- Author verifiable math and physics problems at PhD difficulty
- Evaluate model reasoning traces for correctness and logical validity
- Design automated verifiers for deterministic STEM benchmarks
Ideal Qualifications
- PhD in mathematics, physics, or related STEM field
- Experience writing competition-level math or proof-based problems
