Welocalize • Brazil
Welocalize is seeking a Portuguese (BR) Culture and Language Expert to evaluate AI-generated responses and improve language models. This freelance role requires strong writing skills and cultural knowledge of Portuguese.
You have a strong background in the Portuguese language, with excellent written communication skills and a keen eye for grammatical accuracy. Your familiarity with cultural nuances in Portuguese allows you to evaluate language effectively and provide high-quality feedback. While a background in teaching is preferred, it is not a strict requirement; your experience in writing or teaching Portuguese will be valuable in this role. You are comfortable with structured tasks, including preference ranking and prompt-response writing, which are essential for improving AI language models.
In this role, you will evaluate AI-generated responses for accuracy, grammar, and cultural relevance, ensuring that the language produced meets high standards. You will identify issues in the responses and provide refined, high-quality rewritten versions to enhance the overall quality of the AI's output. Additionally, you will create natural prompts and responses in Portuguese to improve conversational datasets, contributing to the training of AI systems. Collaboration with global teams will be a key aspect of your work, as you help improve AI language models through structured evaluation and writing tasks.
This freelance contract offers a flexible schedule, allowing you to work from the comfort of your home in Brazil. The project is set to start on January 16, 2026, and will last for four weeks, with a commitment of approximately 20 hours per week. You will be compensated at a rate of $20 USD per hour, providing a competitive pay structure for your expertise in the Portuguese language. We encourage you to apply even if your experience doesn't match every requirement, as we value diverse backgrounds and perspectives.
