Core Responsibilities

Primary Functions

Design and execute large-scale corpus analyses to measure word frequency, collocation strength, semantic drift, and lexical variation across domains and time, producing reproducible reports and dashboards for product and content teams.
Build, maintain, and curate production lexicons, gazetteers, stopword lists, and controlled vocabularies to support search relevance, tagging pipelines, and content classification systems.
Develop and maintain robust text preprocessing pipelines (tokenization, sentence segmentation, normalization, stemming/lemmatization) in Python using libraries such as spaCy, NLTK, Hugging Face Transformers, and custom regex rules.
Perform part-of-speech (POS) tagging, named entity recognition (NER), morphological analysis, and dependency parsing to extract structured linguistic features for downstream models and analytics.
Annotate, validate, and manage high-quality labeled training datasets for supervised NLP tasks (classification, sequence labeling), including creating annotation guidelines and performing inter-annotator agreement analysis.
Train, fine-tune, and evaluate language models and classification systems (classical ML and transformer-based models) to improve intent detection, sentiment analysis, and topic classification accuracy.
Design experiments and A/B tests to measure the impact of lexical or model changes on business metrics such as search CTR, query success rate, relevance, and conversion.
Create and maintain clear, versioned documentation for linguistic resources, processing pipelines, annotation schemas, and model evaluation protocols to ensure reproducibility and compliance.
Collaborate with product managers, UX researchers, content strategists, and data engineers to translate business requirements into NLP tasks and prioritized technical work.
Implement rigorous quality assurance and error analysis workflows: log error cases, cluster failure modes, propose fixes (rules or model updates), and track regression risks.
Build interactive dashboards and visualizations (e.g., wordclouds, co-occurrence graphs, frequency timelines) to communicate insights to stakeholders using tools such as Tableau, Looker, or D3.
Optimize and productionize text-processing services (APIs, microservices) and ensure low-latency, scalable deployments with containerization (Docker) and CI/CD practices.
Conduct lexical gap analysis for content strategy and SEO: identify underrepresented terms, synonyms, and regional variants to inform content creation and metadata enrichment.
Establish and monitor linguistic KPIs (vocabulary coverage, false positive/negative rates, annotation throughput) and present periodic reviews to leadership.
Integrate linguistic resources with search engines and information retrieval systems (Elasticsearch, Solr), tuning analyzers, token filters, and scoring functions to improve relevance.
Lead or contribute to cross-functional initiatives for multilingual support: designing language-agnostic pipelines, aligning tokenization and normalization strategies across locales, and coordinating localization priorities.
Evaluate external linguistic and NLP vendors, open-source models, and APIs (e.g., Hugging Face models) for feasibility, cost, and integration risk.
Conduct privacy-aware handling of text data: de-identification, PII detection, and adherence to legal/regulatory requirements in annotated corpora and production systems.
Mentor junior analysts and annotators, review code and annotation work, and support knowledge transfer to grow internal capabilities in text analytics and linguistics.
Stay current with advances in computational linguistics, transformer architectures, embeddings, and lexical resources; propose R&D experiments to pilot emerging techniques.
Translate complex linguistic analysis into executive-ready summaries and tactical recommendations that inform product roadmaps, search strategies, and content taxonomy improvements.
Create reusable tooling (CLI scripts, notebooks, validation suites) that accelerates linguistic analysis, dataset curation, and model evaluation across teams.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
Lead periodic training sessions for content, editorial, and product teams on linguistic conventions, keyword strategy, and how to interpret model outputs.
Support data governance by tagging datasets, labeling sensitive terms, and maintaining provenance for linguistic resources.
