Portuguese (Portugal) Data Labeling Associate - WA based

Welo Data • Redmond, WA

About The Position

Welo Data is seeking Data Labeling Associates for Project Perseus. This role is not a traditional annotation position; instead, it involves working at the intersection of human judgment and machine learning. The associate will evaluate how cutting-edge AI systems handle Portuguese (Portugal) language nuances, cultural context, and safety boundaries. The mission is to achieve human-in-the-loop excellence by critiquing AI outputs for accuracy, fluency, and tone, identifying bias, risks, and failure modes in datasets, and refining evaluation frameworks. Associates will also provide strategic insights into model performance and participate in collaborative calibration to ensure consistent quality across global AI workstreams. This is an opportunity to play a direct role in how AI systems are evaluated and improved, in a fast-moving and collaborative environment.

• AI Safety Expertise: 2+ years of experience focusing on Safety & Trust in Generative AI data delivery.
• Critical Thinking: The ability to make sound judgment calls in ambiguous "grey area" scenarios.
• Technical Agility: A natural curiosity about LLMs and the confidence to flag issues when a model's behavior feels "off."

Responsibilities

• Model Evaluation: Critique Arabic AI outputs for accuracy, fluency, and tone, providing structured feedback to drive model improvement.
• Safety Engineering: Use your 2+ years of GenAI safety experience to identify bias, risks, and failure modes in Arabic datasets.
