About the role

At Anyone AI, we create high-quality training and evaluation data for frontier AI models.

  • Assess accuracy, helpfulness, instruction-following, clarity, and overall response quality.

  • Follow detailed rating guidelines and multi-step evaluation workflows.

  • Write clear, well-reasoned explanations supporting your evaluation decisions.

  • Apply evaluation criteria consistently across tasks.

What we're looking for

  • Fluency in English, with strong reading comprehension and writing skills.

  • Extensive hands-on experience using LLMs and critically assessing their outputs.

  • Strong analytical judgment and the ability to weigh multiple dimensions of response quality.

  • Excellent attention to detail and the ability to follow complex instructions carefully.

  • Ability to explain evaluation decisions clearly and convincingly.

  • Comfort switching between AI models, tools, and multi-step workflows.

Nice to have

  • Previous experience in AI response evaluation, data annotation, or quality assurance.

  • Experience in editing, research, fact-checking, or analytical writing.

  • Familiarity with evaluation rubrics and side-by-side comparison tasks.

Good to know if you are moving

  • All Spain-based roles are fully remote, offering flexibility for international professionals.
  • The company hires domain experts (e.g., mathematics, physics, biology) to train AI models, making it a unique opportunity for academics and specialists.
  • As a US-based company, salaries and contracts may be structured under Spanish employment laws, but specifics should be confirmed during the hiring process.
  • The company is small, so employees may have a direct impact on AI training processes and product development.
  • Working with a US-based company from Spain may require managing time zone differences, though remote work mitigates this.
