Senior NLP Analyst

#ONSITE

We are looking for a highly experienced NLP Analyst with deep expertise in linguistic data analysis, annotation design, and production-scale NLP model evaluation. This role requires a blend of linguistic acumen, analytical rigor, and real-world application experience. You will drive the design and execution of NLP initiatives across diverse domains and guide cross-functional teams on best practices in language data handling and annotation quality.

 

Key Responsibilities

• Manage large-scale text annotation and labeling pipelines for supervised and semi-supervised learning.
• Conduct advanced linguistic analysis of unstructured content (e.g., clinical notes, legal contracts, customer communications, claim documents) to identify patterns, gaps, and modeling opportunities.
• Define and enforce annotation schemas and QA protocols for complex NLP tasks (e.g., NER, relation extraction, coreference resolution, sentiment/intent classification).
• Evaluate and improve the performance of NLP models through rigorous error analysis and metric-driven feedback loops.
• Collaborate with ML/NLP engineers, data scientists, and domain experts to build robust NLP pipelines that scale across use cases.
• Lead internal research efforts on emerging NLP methodologies, including LLM prompt engineering, hybrid rule-learning approaches, and few-shot learning.
• Provide mentorship to junior analysts and contribute to developing internal NLP knowledge repositories and annotation standards.

 

Required Qualifications

• Master’s in computational Linguistics, NLP, Data Science, Computer Science, or a related field.
• 5+ years of professional experience in NLP, with a strong track record of hands-on work in data annotation, language model evaluation, and NLP pipeline development.
• Expertise in Python and key NLP libraries (spaCy, NLTK, Scikit-learn, Hugging Face Transformers, etc.).
• Advanced proficiency in building and managing annotation workflows using tools like Prodigy, doccano, Brat, or in-house platforms.
• Deep understanding of linguistic structures (syntax, semantics, pragmatics) and their application to real-world NLP challenges.
• Experience evaluating ML/NLP models using metrics like F1, ROUGE, BLEU, precision/recall, and embedding-based similarity.
• Solid grasp of vectorization methods (TF-IDF, embeddings, transformer-based encodings) and modern language models (e.g., BERT, GPT, LLaMA).

 

Preferred Qualifications

• Experience with domain-specific NLP (e.g., clinical/biomedical, legal, fintech).
• Knowledge of knowledge graph construction, relation extraction, and entity linking.
• Experience integrating structured/unstructured data for downstream AI/ML applications.
• Familiarity with prompt engineering for LLMs and tuning foundation models.
• Strong data querying and visualization skills (SQL, pandas, seaborn, Power BI/Tableau).

Key Responsibilities

• Preprocess and clean raw text data for downstream NLP applications (e.g., tokenization, normalization, entity recognition).
• Annotate and label datasets for supervised learning tasks (e.g., intent classification, sentiment analysis, NER).
• Analyze and visualize linguistic patterns and insights from textual data.
• Work with data scientists to evaluate and improve model performance.
• Support the development of rule-based and machine learning-based NLP pipelines.
• Document and maintain guidelines for annotation and linguistic QA.
• Collaborate with stakeholders to understand domain-specific language challenges and requirements

 

Required Qualifications

• Bachelor’s degree in Linguistics, Computer Science, Data Science, or a related field.
• 3+ years of hands-on experience with text analysis or NLP tasks.
• Proficiency in Python and common NLP libraries (e.g., spaCy, NLTK, pandas).
• Experience working with annotation tools (e.g., Prodigy, Labelbox, doccano).
• Strong understanding of language structure and linguistic features.
• Ability to apply regular expressions and text parsing techniques effectively.
• Familiarity with data visualization tools and basic statistics.

 

Preferred Qualifications

• Experience in domain-specific NLP (e.g., clinical/biomedical, legal, financial).
• Knowledge of vectorization methods (TF-IDF, word2vec, BERT embeddings).
• Exposure to ML model evaluation metrics (e.g., precision, recall, F1 score).
• Experience with SQL and working with large datasets.
• Familiarity with LLMs (e.g., OpenAI, Hugging Face Transformers).
