Core Responsibilities

Primary Functions

Lead end-to-end document ingestion and normalization pipelines: design workflows to collect PDFs, scanned images, emails, contracts, spreadsheets and other file types, orchestrate OCR, convert to canonical text, and produce validated, structured outputs for downstream systems.
Build and maintain high-accuracy OCR and layout extraction solutions using tools like Tesseract, ABBYY, Google Vision, or AWS Textract, including pre- and post-processing to handle variable scan quality, languages, fonts and document templates.
Implement and tune NLP models for document classification, named entity recognition (NER), relation extraction, and slot-filling to convert unstructured text into structured entities and events for business consumption.
Design and execute annotation programs, labeling schemas and quality assurance processes for human-in-the-loop training data; manage annotation vendors and internal annotators to reach label consistency and high inter-annotator agreement.
Develop and maintain semantic search and vector similarity pipelines (e.g., Elasticsearch, OpenSearch, Vespa, Pinecone, Milvus) to enable fast, relevant retrieval of document passages for search and RAG applications.
Integrate document pipelines with LLMs and retrieval-augmented generation flows, including prompt design for contextual grounding, chunking strategies, and hallucination mitigation to produce reliable answers surfaced by chatbots and virtual agents.
Create and maintain metadata schemas, taxonomy and canonical field definitions to ensure consistent document indexing, lineage tracking and discoverability across enterprise systems.
Author and maintain transformation scripts, parsers and mapping logic to extract tables, forms, invoices, purchase orders and structured records from heterogeneous document formats.
Monitor and troubleshoot production document pipelines, including latency, error rates, model drift, throughput, and model performance regressions; implement alerting, logging and automated remediation where possible.
Establish and measure KPIs for document quality (precision/recall/F1), pipeline SLA, annotation throughput, extraction accuracy by document type, and end-user satisfaction; deliver regular reporting to stakeholders.
Enforce data governance, compliance and security practices for document storage, access controls, redaction and PII handling to meet regulatory and internal policy requirements.
Collaborate with product managers, legal, compliance and customer support to prioritize document types, business rules, and accuracy thresholds based on downstream impact and ROI.
Prototype and evaluate new document understanding techniques (layoutLM, Donut, OCR+LLM hybrids, sequence labeling ensembles) and productionize the most effective approaches while maintaining reproducibility and model versioning.
Implement continuous evaluation and A/B testing frameworks to compare extraction models, search ranking changes, and conversational grounding strategies in real usage scenarios.
Create and maintain APIs, microservices and ingestion endpoints for downstream consumers to query extracted entities, document metadata, and passage-level retrieval results.
Optimize document chunking, indexing and retrieval strategies to balance response time, token usage for LLM calls, and retrieval relevance for conversational agents and knowledge search.
Drive cross-functional knowledge transfer by writing runbooks, system designs, onboarding guides and contributing to data dictionaries to increase organizational adoption and reduce single points of knowledge.
Collaborate with engineering teams to containerize, deploy and scale document processing components using Docker, Kubernetes and cloud-native services on AWS/GCP/Azure.
Manage vendor relationships and evaluate SaaS/ML platforms for document processing, OCR, and annotation to complement in-house capabilities and reduce time-to-value.
Lead incident response for document pipeline outages or critical extraction failures, coordinate mitigation steps, communicate status to stakeholders, and implement post-mortems with actionable improvements.
Tailor document processing solutions for domain-specific content (legal contracts, healthcare records, financial statements) including custom ontologies, domain adaptation, and expert review loops.
Develop data pipelines that integrate extracted document data with data warehouses, knowledge graphs, or feature stores for analytics, reporting and ML model training.
Provide hands-on support for customer-facing pilots and proofs-of-concept, including scoping, data onboarding, success metrics, and transition plans for production deployment.
Maintain continuous improvement cycles: run retrospectives, prioritize backlog items, and implement automation to lower manual triage and increase throughput and accuracy of document operations.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis from cross-functional teams to identify document-related opportunities and pain points.
Contribute to the organization's data strategy and roadmap by recommending investments in tooling, models and annotation scale that unlock business value from documents.
Collaborate with business units to translate data needs into engineering requirements, prioritizing document sources and fields that impact KPIs.
Participate in sprint planning and agile ceremonies within the data engineering team.
Conduct training sessions and workshops for product teams and support agents on how to query and leverage the document knowledge base and retrieval tools.
Maintain and update glossaries and taxonomies based on feedback loops from subject-matter experts and production usage patterns.
Support sales engineering and customer success teams with sample outputs, demos, and technical documentation to accelerate customer onboarding.
Assist legal and security teams in data retention, redaction workflows and audit requests related to scanned or digitized documents.
Contribute to open-source projects or internal libraries that improve document parsing, OCR cleaning and evaluation tooling.
Help design incentives and QA programs for annotation contributors to improve label speed and accuracy over time.
