NLP Engineer (Natural Language Processing)
For those fascinated by the complexity of human language — NLP engineering turns the richness of text and speech into machine intelligence that powers the next generation of AI products.”
About This Role
Develops AI systems that can understand and process human language (voice/text).
A Day in the Life
NLP Engineers build systems that understand and generate human language — training language models, building text pipelines, developing chatbots, and deploying models to process millions of text documents or power conversational AI products.
- Design and train NLP models (text classification, NER, summarisation)
- Build and maintain text preprocessing pipelines
- Fine-tune pre-trained language models (BERT, GPT, LLaMA)
- Develop and deploy chatbot and conversational AI systems
- Evaluate model performance with NLP metrics (F1, BLEU, ROUGE)
- Integrate NLP APIs into product features
- Research and implement latest NLP techniques from papers
