NLP Engineer

Role Description

This role involves building language pipelines for classification, retrieval-augmented generation (RAG), and tokenization. You’ll design robust text analytics and evaluation frameworks that scale across multilingual corpora, powering advanced AI-driven systems.

• Build NLP pipelines for classification, tokenization, and RAG tasks
• Design scalable text analytics workflows that support multilingual datasets
• Implement and fine-tune models with Hugging Face Transformers, PyTorch, and fastText
• Develop evaluation frameworks for model performance across diverse corpora
• Integrate NLP solutions into broader AI pipelines, including search and retrieval systems
• Collaborate with AI researchers and engineers to ship robust, production-grade NLP systems

Qualifications

• Have a background in computer science, computational linguistics, or related fields
• Proficient with Hugging Face Transformers, spaCy, tokenizers, and PyTorch
• Experience working with text formats like JSON/JSONL and building scalable data pipelines
• Understand NLP tasks such as classification, entity recognition, tokenization, and retrieval
• Comfortable working with multilingual corpora and designing evaluation benchmarks
• Strong experience with text preprocessing, embedding generation, and model fine-tuning
• Curious about building RAG systems and neural search pipelines that combine IR and NLP

Requirements

• Design and ship NLP pipelines for classification, tokenization, and RAG that can handle large-scale, multilingual corpora

Benefits

• Classified as an hourly contractor to Mercor
• Paid weekly via Stripe Connect, based on hours logged
