English & Hausa NLU Annotator at Transsion Holdings

About the Role

• We are seeking a bilingual (English & Hausa) NLU Annotator to join our language AI team. You’ll support the development of robust Natural Language Understanding (NLU) systems by accurately annotating, labeling, and evaluating text data in both languages. A minimum of 1 year of NLU/data annotation experience is required.

Key Responsibilities

• Annotate and label text data in English and Hausa according to project-specific guidelines (e.g., intent classification, entity tagging, sentiment, slot filling, etc.)
• Review, validate, and refine AI-generated annotations to ensure high quality and consistency
• Coordinate with NLP engineers and linguists to resolve ambiguous or complex annotation cases
• Document annotation decisions, flag patterns or issues, and suggest improvements to guidelines
• Perform quality assurance checks to maintain high inter-annotator agreement

Qualifications

• Native or near-native fluency in both Hausa and English (written + spoken), with strong grammar and cultural nuance understanding
• At least 1 year of experience in NLU, NLP, or data annotation roles involving intents, entities, or conversational understanding
• Strong linguistic background: familiarity with syntax, semantic roles, NER, etc.
• Attention to detail, critical thinking, and ability to work with large datasets
• Experience with annotation tools/platforms (e.g., Labelbox, Prodigy, custom tools) is a plus
• Degree in Linguistics, Computational Linguistics, AI, or a related field is preferred but not mandatory

Nice-to-Have

• Experience integrating results into training pipelines for chatbots or voice assistants
• Familiarity with prompt engineering or generative AI contexts
• Past work on low-resource languages or Nigerian language NLU (e.g., Hausa)

What You’ll Gain

• Contribute directly to multilingual AI development and real-world NLU systems
• Collaborate with cross-functional teams (Linguists, Data Scientists, Engineers)
• Opportunity to influence annotation standards and help shape future guidelines
• Flexible and engaging work environment: remote/hybrid options available
