• Lead multilingual dataset curation, annotation, enrichment, and ground-truth creation to support AI model development and evaluation.

• You understand language quality, cultural relevance, content quality, and user experience across multiple languages and markets.
• You have experience designing or conducting structured evaluations using quality rubrics, audits, annotation projects, or review methodologies.
• You are comfortable using qualitative and quantitative data to identify trends, measure quality, and make recommendations.
• You are familiar with large language models (LLMs), generative AI evaluation, human‑in‑the‑loop workflows, or LLM‑as‑a‑judge methodologies.
• You enjoy working through ambiguity and turning complex quality challenges into practical evaluation strategies.
• You communicate effectively and thrive in highly cross‑functional environments, collaborating with technical and non‑technical partners alike.
• Experience with recommendation systems, personalization, search, ranking, machine translation, generative AI, dataset creation, annotation operations, evaluator calibration, prompt testing, model evaluation, SQL, Python, dashboards, or annotation platforms is a plus.

Where You’ll Be:

• This role is based in London or Stockholm.
• We offer you the flexibility to work where you work best! There will be some in person meetings, but still allows for flexibility to work from home.
