Bulgarian Trilingual Language Specialist - Freelance AI Trainer Project

Are you fluent in Bulgarian, English, and at least one additional language, and eager to apply your linguistic expertise to the future of AI? Large-scale language models are transforming how people communicate, learn, and access information across cultures. With high-quality multilingual training data, tomorrow’s AI can better serve global communities with accuracy, nuance, and inclusivity. That training data begins with you.

We’re looking for a Bulgarian Trilingual Language Specialist who can bring deep linguistic knowledge, cultural awareness, and multilingual proficiency to AI training. You’ll work with cutting-edge AI tools to evaluate, annotate, and refine model outputs in Bulgarian, English, and your third language, helping improve cross-lingual reasoning, translation quality, and naturalness.

On a typical day, you will review AI-generated text for grammatical accuracy, idiomatic expression, and cultural appropriateness; annotate and correct linguistic errors; assess multilingual translations for clarity and fidelity; and collaborate with our team to strengthen evaluation protocols and language-specific guidelines.

Fluency in Bulgarian and English, plus proficiency in at least one additional language, is required. Prior experience in translation, linguistics, content evaluation, or AI training is strongly preferred. Clear communication skills, attention to detail, and the ability to articulate linguistic nuances across languages are essential.

Ready to apply your multilingual expertise to shape the AI of tomorrow? Apply today and help build tools that will empower communication for people worldwide.

We offer a pay range of $6 to $65 per hour, with the exact rate determined after evaluating your experience, expertise, and geographic location.
