Position Summary

We are seeking a specialist with experience designing, training, and operationalizing intelligent document-processing solutions. The ideal candidate combines applied AI and machine learning expertise with cloud data engineering, secure information handling, and configurable business-rule automation. This role focuses on turning unstructured and semi-structured documents into accurate, auditable, and actionable data products.

Core Technical Skills

Intelligent Document Processing (IDP), optical character recognition (OCR), and document classification

Training, evaluating, and tuning document extraction models for structured, semi-structured, and handwritten content

Entity and field extraction, confidence scoring, quality metrics, and model accuracy assessment

Document preprocessing, page-level validation, exception detection, and human-in-the-loop review patterns

Python development for data processing, automation, model integration, and reusable components

Cloud-native data pipelines using object storage, analytical databases, batch processing, and job orchestration

Configuration-driven validation using YAML or similar formats to separate business rules from application code

Data normalization, reconciliation, tolerance handling, and comparison against authoritative data sources

Encryption, decryption, sensitive-data controls, auditability, and secure cloud processing

API and system integration for ingesting documents, publishing results, and supporting downstream workflows

Applied AI and Machine Learning

Practical experience with document AI platforms or comparable machine learning services

Understanding of supervised model training, labeling strategies, evaluation datasets, confidence thresholds, and error analysis

Ability to identify when OCR, rules-based logic, machine learning, or generative AI is the appropriate solution

Experience applying large language models to document understanding, unstructured content analysis, summarization, or reasoning use cases

Knowledge of responsible AI practices, including explainability, traceability, quality controls, and review escalation

Data and Platform Engineering

Experience with cloud object storage, SQL-based analytical platforms, and production data pipelines

Batch and event-driven processing patterns, workflow orchestration, retries, monitoring, and operational support

Data modeling for extracted values, confidence scores, validation results, and processing history

CI/CD, source control, automated testing, environment promotion, and infrastructure-as-code practices

Observability and troubleshooting across model, application, data, and integration layers

Business and Delivery Capabilities

Ability to translate document-review procedures into clear technical requirements and configurable validation rules

Collaboration with business subject-matter experts to define fields, thresholds, exceptions, and acceptance criteria

Clear documentation of model behavior, processing logic, decision outcomes, and operational procedures

Ability to communicate complex AI and data-processing concepts to technical and non-technical stakeholders

Focus on scalable, reusable solutions rather than one-off document automations

Required Qualifications

Bachelor's Degree in Information Systems, Computer Science, Data Analytics, or related technical field

Hands-on experience delivering document-processing or information-extraction solutions in a regulated industry

Experience with sensitive or confidential information and enterprise security controls

Familiarity with cloud-based machine learning and data platforms

Knowledge of financial-services, legal, healthcare, insurance, or other document-intensive workflows

Experience designing exception-based workflows that reduce manual review while preserving quality and control
