You will design, build, and maintain robust data pipelines and information extraction workflows, directly impacting strategic analytics and decision-making processes. This is a chance to apply your expertise in large language models and data engineering to solve real-world challenges, delivering verifiable answers and actionable intelligence that will shape the company’s future direction.

What You’ll Do

• Architect, build, and refine retrieval-grounded LLM systems, including advanced RAG patterns, to deliver grounded, verifiable answers and insights.
• Design robust pipelines for ingestion, transformation, and normalization of public and internal data, including ETL, incremental processing, and data quality checks.
• Build and maintain document processing workflows across various formats like PDFs, HTML, and scanned content, incorporating OCR, layout-aware parsing, table extraction, metadata enrichment, and document versioning.
• Develop information extraction pipelines using LLM methods and best practices, including schema design, structured outputs, validation, error handling, and accuracy evaluation.
• Own the retrieval stack end-to-end, encompassing chunking strategies, embeddings, indexing, hybrid retrieval, reranking, filtering, and relevance tuning across vector databases or search platforms.
• Implement web data acquisition where necessary, including scraping, change detection, source quality checks, and operational safeguards like retries and rate limiting.
• Establish evaluation and monitoring practices for retrieval and extraction quality, including golden datasets, regression testing, groundedness checks, and production observability.
• Collaborate with subject matter experts to translate business needs into practical retrieval and extraction workflows and measurable success criteria.
• Communicate complex findings, tradeoffs, and recommendations to technical and business stakeholders, supporting data-driven forecasting and strategy.
• Ensure compliance with data governance and security standards when handling sensitive data and deploying systems to production environments.

Required Skills & Experience

• Advanced degree in Computer Science, Data Science, Statistics, Engineering, or a related quantitative field.
• Minimum of 4 years of experience in data science or applied ML/NLP with a strong focus on NLP & Generative AI.
• Proficiency in Python and SQL, coupled with strong engineering practices for building maintainable, testable pipelines.
• Strong experience with Databricks for data processing and pipeline development, including Spark and common lakehouse patterns.
• Demonstrated experience building retrieval-grounded LLM systems or LLM-based information extraction solutions for real-world use cases.
• Experience with document ingestion and parsing, including OCR and handling messy, semi-structured content such as PDFs, tables, forms, and web pages.
• Familiarity with vector databases and retrieval concepts, including indexing, embeddings, hybrid retrieval, reranking, and performance and cost tuning.
• Strong understanding of best practices for reasoning models and techniques that improve reliability and reduce hallucinations, including grounding and attribution.
• Excellent communication skills, with a proven track record of partnering with stakeholders and transforming ambiguous requests into adopted solutions.
• Proficiency with LLM and orchestration libraries such as openai, google-genai, langgraph, and langchain.
• Experience with supporting tooling commonly used in production LLM systems, for example: pydantic for schema validation, tenacity for retries, beautifulsoup4 for HTML data extraction, and standard Python data tooling such as pandas and numpy.
• Experience with retrieval and vector tooling, such as FAISS, Elasticsearch or OpenSearch, and vector database platforms (e.g., Pinecone, Weaviate, Milvus, Chroma).

Preferred Skills

• Exposure to agentic patterns and tool-calling for workflow automation.
• Experience working in regulated environments and implementing governance controls such as access control, auditability, and retention.

The target hiring compensation range for this role is $57.83 to $64.26 an hour. Compensation is based on several factors including, but not limited to education, relevant work experience, relevant certifications, and location.
