AI Localization Prompt Engineer

Marcus Sokolov

Full-time · Job · Madrid

About the role

The prompts you write will run in front of 40,000 daily translation requests across 22 languages. That's the honest scale of the AI Localization Prompt Engineer role, and it's why we care so much about getting prompt structure and fallback handling right. You'll design and version prompt templates for our translation and cultural-adaptation pipeline, test them against native-speaker review panels, and iterate based on real production feedback rather than guesswork. This role sits at the intersection of linguistics and engineering, and you'll work closely with our localization QA team on every release.

Responsibilities

  • Design and version prompt templates for translation workflows
  • Run evaluation cycles with native-speaker review panels
  • Debug prompt failures across low-resource language pairs
  • Maintain a prompt changelog for the localization pipeline

Requirements

  • 2-4 years of experience with LLM prompt engineering
  • Familiarity with Hugging Face models and APIs
  • Interest in linguistics or multilingual NLP
  • Experience with AWS-hosted inference endpoints

Benefits

  • Fully remote position
  • Competitive salary
  • Health coverage
  • Language-learning stipend
