You’ll collaborate daily with US-based engineers and product stakeholders as an individual contributor.

Key Responsibilities:

• Design, train, and deploy ML models for text classification, entity extraction, clustering, and narrative and topic detection

• Build and improve LLM-powered features, including prompt design, retrieval-augmented generation (RAG), and agentic workflows

• Develop embedding and semantic-search pipelines to group related content and surface emerging threats

• Productionize models as scalable, monitored services with clear latency, cost, and accuracy targets

• Build evaluation frameworks and datasets to measure model quality, bias, and drift over time

• Work with data engineering to improve ingestion, labeling, and feature pipelines for high-volume, noisy, multilingual text data

• Monitor and retrain models in production, and debug quality issues end to end

• Join daily standups and technical discussions with the US-based
